3/11/2008 #33 19_2 Blood Types Notes p.553 (2 columns) 1. If blood of the wrong types is mixed, it will clot and can block blood flow to any part of the body. 2. Blood type is determined, in part, by the ABO blood group antigens present on red blood cells. 3. The antigens and antibodies in blood is what determines a blood type. Antibodies react in response to antigens and clots form. 4. Copy Table 1 on page 533 in the left column. Copy Table 2 on page 533 in the right column. 5. Different blood types have different chemical tags called antigens. 6. Different blood types also have different antibodies. 7. Antibodies are proteins that destroy or neutralize substances that are not part of your body. 8. Antibodies are what cause transfused blood to clot. 9. Rh is another chemical blood tag. Rh+ has the Rh factor or tag, while Rh – doesn't. 10. When an Rh – mother is pregnant with an Rh + baby, the mother might make antibodies to the child's Rh factor. 11. Just before birth, the mothers antibodies can get into the child and destroy the baby's RBCs or red blood cells. 12. Injections that keep the mother from making these antibodies are given to these mothers to protect the babies blood cells. 13. With anemia, bodies tissues don't get enough oxygen from the blood. 14. Blood loss or lack of iron in the diet can cause anemia. 15. In sickle-cell disease, blood cells are misshapened, so they clog the capillaries. 16. Sickle-cell disease is inherited and results in poor oxygen and carbon dioxide exchange between the blood and tissue cells. 17. In Leukemia, many immature and none functioning white blood cells are produced.

3/10/2008 #32 19_2 Blood Notes (2 Columns) 1. Four Functions of Blood: Delivers oxygen to and removes Carbon dioxide from body cells Carries waste from body cells to the kidneys Transports nutrients to the body cells Fights infections and helps heal wounds 2. Diseases that disrupt the four functions of blood, can affect all the cells of your body 3. Blood tissue consists of plasma, platelets, red cells, and white cells. 4. An adults blood would fill five 1-L Bottles 5. Plasma is mostly water and is the liquid part of the blood. 6. Plasma is half of the bloods volume. 7. Nutrients, minerals and wastes are dissolved in and transported by plasma. 8. Red Blood Cells: (RBCs) are disk shaped, have no nuclei, contain hemoglobin 5,000,000 in each mm3 of blood 9. Hemoglobin carries oxygen to cells from the lungs and carbon dioxide away from cells to the lungs. Why do we breath in oxygen? Our cells combine oxygen with food to make ATP for energy. Where does the carbon dioxide that we breath out come from? Carbon in food is combine with oxygen to make carbon dioxide. 10. RBCs live about 120 days. About 2.5 million RBCs are produced each second and are destroyed at the same rate. (2,000,000 to 3,000,000) 11. RBCs are produced in the marrow of long bones. 12. White blood cells (WBCs) fight bacteria, viruses and other invaders of the body. Some WBCs engulf invaders, while other WBCs release antibodies that disable invaders. 13. There are five major kinds of WBCs. Some WBCs break down body cells that die as well as fighting infections. 1 Lymphocytes 2 Monocytes 3 Neutrophils 4 Basophils 5 Eosinophils 14. There are about 1 or 2 WBCs for every 1000 RBCs and they live from a few days to a few months. (5,000 to 10,000 WBCs in each mm3 of blood) 15. Platelets: are irregular shaped cell fragments, help clot blood, last five to nine days, stick to damaged cells, and release chemicals called clotting factors 16. Blood Clotting: platelets stick to wounded cells, clotting factors from platelets cause fibers called fibrin to form, fibrin blocks blood cells like a net, and then fibrin and blood cells harden forming a scab. 17. A person with a low number of platelets can bleed without it stopping 18. Hemophilia is a genetic condition where plasma lacks a clotting factor, so minor wounds can cause one to bleed to death.

Assignment #28 Participation grade for 2/25 to 2/29. Students have to be present and following classroom norms to earn these points..

2/28/08 and 3/3/08 #27 19-1 Circulatory System Notes Two Columns p. 540 1. Blood moves oxygen and nutrients to every cell in your body and carries away carbon dioxide and other wastes. 2. The movement of substance between blood and cells occurs by diffusion and active transport. 3. Diffusion is the spreading out of a substance from an area of high concentration to an area of low concentration. (Diffusion is when a material moves from where there is more of it to where there is less of it.) 4. The two upper chambers of the heart are called right and left atriums and the two lower chambers are called right and left ventricles 5. Both atriums contract together and then both ventricles contract together to make the lub-dub sound. 6. Coronary circulation consist of the coronary arteries and coronary veins. 7. Path of blood through the heart: a. Blood returns to the heart through the vena cavas from the body. b. Right atrium receives blood from the vena cavas. c. The right atruim loads the right ventricle with blood. d. The right ventricle pumps blood into the pulmonary arteries. e. Pulmonary circulation starts with the pulmonary arteries, goes to the lungs, and finishes with the pulmonary veins. f. Oxygen is picked up and carbon dioxide is dropped off in the lungs. G. Oxygenated blood enters the left atrium from the pulmonary vein. H. The left atrium loads the blood into the left ventricle. I. The left ventricle pumps blood to the body through the aorta. J. The Aorta starts systemic circulation, goes to the capillaries, and finishes with the vena cava. K. Oxygen-rich blood enters the aorta and oxygen-poor blood leaves the vena cava. 8. Arteries carry blood away from the heart. 9. Arteries and veins have thick elastic walls made of connective tissue and smooth muscle. 10. Each ventricle is connected to an artery. Right ventricle- Pulmonary artery/Left ventricle- Aorta 11. The smooth muscle in arteries is thicker than in veins, so they can handle the high pressure. 12. Veins carry blood back to the heart. 13. Veins have one-way valves that keep blood moving back towards the heart. 14. The superior vena cava returns blood from the head and neck, while the inferior vena cava returns blood back from the abdomen and legs. 15. Capillaries connect arteries to veins. 16. Capillaries are only one cell thick, so oxygen and nutrients can diffuse out to the cells and carbon dioxide and wastes can diffuse in. 17. Blood pressure is the force of pumped blood on the walls of blood vessels. 18. Blood pressure is higher in arteries than in veins. 20. Blood pressure is controlled by the speed of the heart and the squeezing of smooth muscles in the arteries and veins. 21. Cardiovascular diseases or diseases of the heart, blood vessel, and blood are the leading cause of death in the US. (1. for teens is accidents and injury) 22. Atherosclerosis is when fatty deposits build up on the walls of arteries. 23. Eating foods high in cholesterol and saturated fats can cause fatty deposits to build up on artery walls. 24. Fatty deposits in coronary arteries cause heart attacks. 25. Hypertension or high blood pressure can be caused by atherosclerosis 26. Clogged arteries lose their elasticity and no longer dilate or contract easily, causing high blood pressure. 27. Hypertension can cause the heart to weaken (heart failure) and damage the kidneys. (dialysis) 28. Heat failure results when the heart cannot pump blood efficiently 29. Heat failure is caused by weak heart muscle tissue or damaged heart valves 30. In heart failure people are short of breath and fluid collects in their arms, legs, and lungs 31. Healthy diet and exercise choices greatly reduces the chances of cardiovascular disease and cancer. 32. Many people get cardiovascular by eating diets high in saturated fats, cholesterol, and sugar. (Eating too much sugar causes diabetes which causes heart disease.) 33. Large amounts of body fat force the heart to pump faster and is associated with cardiovascular disease. 34. Regular exercise helps to prevent tension, control cholesterol, lower blood pressure, reduce body fat, and strengthens the heart and lungs. 35. Smoking causes the blood vessels to contract causing the heart to beat faster and harder. 36. Smoking causes cardiovascular disease and lung cancer.

2/19/08 and 2/20/08 #20 18_2 Notes / 2 Column Write the following as two column notes. Remember, the more thinking you do in creating your second column, the better you will do on the test. 1. To process food, the body must ingest, digest, absorb and eliminate it. 2. The breaking down of food for absorption is called digestion. 3. The chewing, mixing and churning of food is mechanical digestion. 4. The chemical reactions that break large molecules into smaller ones is chemical digestion. 5. The chemical reactions that break large molecules into smaller ones require enzymes. 6. The proteins that speed up chemical reactions are called enzymes. 7. While speeding up reactions, enzymes work without being changed. 8. The teeth and tongue in the mouth start mechanical digestion. 9. Glands in the mouth secrete saliva which contains water, mucus, and amylase. 10. The enzyme that breaks starches into sugars is called amylase. 11. The bodies main source of energy are carbohydrates. 12. Food is made more slippery by mucus to protect the digestive tract.. 13. The structure that covers the windpipe when food is swallowed is called the epiglottis. 14. The esophagus is a muscular tube between the mouth and stomach. 15. The waves of muscular contractions that push food through the digestive tract is peristalsis. 16. The churning, expandable, muscular bag that holds food is the stomach. 17. Hydrochloric acid is added to food in the stomach. 18. HCL acid and the enzyme pepsin break down proteins in the stomach. 19. Acid in the stomach also kills most bacteria found in food. 20. Food liquidized for and by digestion is called chyme. 21. Nutrient absorption is the main function of the small intestine. 22. The liver makes bile which is held in the gall bladder. 23. The gall bladder releases bile into the small intestine. 24.Bile emulsifies fats and oils breaking them into smaller droplets. 25.The pancreas put enzymes into the duodenum or first part of the small intestine. 26. Most digestion takes place in the duodenum. 27. The pancreas produces enzymes that break down carbohydrates, proteins, and fats. 28. The pancreas also produces bicarbonate ions that neutralize stomach acid in the chyme. 29. The surface area of the small intestine is increased by structures called villi. 30. Nutrients move into the blood vessels within the villi. 31. Proteins are broken down into their building blocks called amino acids. 32. Starches are broken down into sugars from which they are composed. 33. Fats are broken down into glycerides and fatty acids. 34. The main job of the large intestine is to absorb water from the undigested mass. 35. The large intestine helps maintain homeostasis by keeping large amounts of water in the body. 36. The last eight inches of the large intestine is the rectum. 37. The rectum holds and then muscles in it help void the waste. 38. Muscles in the anus control the release of semisolid wastes called feces. 39. Beneficial bacteria live in the large intestine also called the colon. 40. Bacteria produce vitamin K and two b vitamins. 41. Vitamin K is important for blood clotting. 42. The two B vitamins, niacin and thiamine are important to the nervous system. 43. Less helpful bacteria breakdown meat and fat wastes into carcinogens. 44. The breakdown of intestinal material by bacteria produces gas. 45. The tongue, teeth, salivary glands, liver, gall bladder and pancreas are called accessory organs because food doesn't pass through them. 46. List all the digestive organs that food passes through:

2/14/08 #19 Digestive Organs Activity (Make-up: Write information on three of the following topics.) Research three topics as a group and then creatively organize the information as a poster.

Bones can change shape when the attached muscles are used. 6. Bones have bumps and pits to which muscles and ligaments attach. 7. Blood vessels and nerves enter and exit through holes in bones 8. Periosteum Tough, attached membrane covering Contains small blood vessels that bring nutrients into the bone. Involved in growth and repair 9. Compact Bone Hard layer under the periosteum Gives bones strength Framework contain calcium and phosphate Contains a network of cells and blood vessels 10. Spongy bone located near the ends of long bones Contains numerous open spaces Gives strength without weight Spaces contain marrow 11. Marrow Yellow marrow consist of fat cells Red marrow cells produce blood cells 12. Cartilage Thick, smooth, and slippery Lacks blood vessels and minerals Near by blood vessels supply nutrients Flexible and acts as shock absorbers Reduces friction between bones Damage causes pain 13. Bone Cells Called osteoblast Deposit calcium and phosphorous Osteoblast build and breakdown the hard part of bones Release calcium and phosphorous into the blood when needed by muscles and nerves
