  2. 1. The two upper chambers of the heart.2. The two lower chambers of the heart.3. Blood vessels that move blood away from the heart.4. Blood vessels that move blood toward the heart A. Arteries B. Atriums K. Veins L. Ventricles

  3. 5. Microscopic blood vessels connecting larger vessels.6. Moves blood to all tissues except lungs and heart.7. Collects fluid from body tissue spaces and returns it to the blood.8. The liquid part of the blood, consisting mostly of water.9. A chemical that can carry oxygen and carbon dioxide C. Capillaries E. Hemoglobin G. Lymphatic System H. Plasma J. Systemic Circulation

  4. Another name for high blood pressure is _____. Atherosclerosis Hypertension Leukemia Thrombosis

  5. Blood in veins is ________. High in oxygen High in nutrients Low in wastes Low in oxygen

  6. In pulmonary circulation, blood flows through two organs, the ______. • Brain and heart • Heart and kidneys • Heart and liver • Lungs and heart

  7. In systemic circulation, blood returns from your abdomen through the inferior vena cava to the _______. • Left atrium • Left ventricle • Right atrium • Right ventricle

  8. Coronary circulation is the flow of blood to the tissues of the ________. • Brain • Heart • Kidneys • Lungs

  9. A heart attack can occur if an artery in the ______ is clogged. • Brain • Heart • Liver • Lungs

  10. When blood moves from an atruim to a ventricle, it must pass through a ________. • One-way alive • Murmur • Semilunar valve • Lymph node

  11. ______, the liquid part of blood, is mostly made of water. • Hemoglobin • Lymph • Plasma • Platelets

  12. Hemoglobin picks up ________. • Carbon Dioxide and oxygen • Carbon dioxide and wastes • Nutrients and carbon dioxide • Oxygen and wastes

  13. _______ help clot blood. • Lymph nodes • Platelets • Red blood cells • White blood cells

  14. _______ is the water and dissolved substances not taken in by cells that remains between the cells. • Hemoglobin • Lymph • Plasma • Thymus

  15. Red blood cells are formed in _______. • Bone marrow • The liver • Muscle • The atria

  16. Anemia is a disorder where there are too few _____ in the blood. • Lymphocytes • Platelets • Red blood cells • White blood cells

  17. Leukemia is a disease in which ____ are produced in great numbers. • Lymphocytes • Platelets • Red blood cells • White blood cells

  18. The _____ fight bacteria and viruses. • Platelets • Hemoglobin molecules • Red blood cells • White blood cells

  19. Which student just ran to class? Students’ Pulse Rates Sue 59 Sally 64 Tom 81 Larry 89 Marge 106 Marge

  20. Which students just woke up? Students’ Pulse Rates Sue 59 Sally 64 Tom 81 Larry 89 Marge 106 Sue and Sally

  21. What do Tom and Larry have in common? Students’ Pulse Rates Sue 59 Sally 64 Tom 81 Larry 89 Marge 106 They both have normal rates

  22. Types of Blood Cells 1. ___________=5 million per 1 mm ; live 120 days; contain hemoglobin 2. ___________=5-10 thousand per 1 mm ; live 30 days; ingest dead cells 3. ___________=400 thousand per 1 mm ; live 5-9 days; odd-shaped fragments 3 3 3 1. Red Blood Cells 2. White blood cells 3. Platelets

  23. In pulmonary circulation, blood from body cells enter the right atrium of the heart through a large vein called the _______________. Vena cava

  24. When the right atrium contracts and blood is forced into the ventricle. The walls of the right ventricle contract and blood leaves the heart through the ___________ to the lungs. Pulmonary artery

  25. As blood circulates through the lungs, __________ is exchanged for oxygen. Carbon Dioxide

  26. This blood then moves to the left atrium and then to the left ventricle. The final step occurs when the left ventricle contracts and blood is forced up and out of the heart into the largest artery of the body, called the __________, and then on to many smaller arteries. aorta

  27. Place in order beginning where blood oxygen is highest. 3 ____ Food and oxygen diffuse from the capillaries to body tissues. ____ Blood enters the heart through the inferior vena cava to the right atrium. ____ Blood leaves the left ventricle through the aorta. ____ Blood travels to smaller arteries and capillaries in the abdomen. 4 1 2

  28. List the four major functions of blood. • It carries oxygen from your lungs to all body cells and removes carbon dioxide from your body cells and carries it to the lungs to be exhaled. • It carries waste products of cell activity to your kidneys to be removed. • It transports nutrients from the digestive system to body cells. • Materials in blood fight infections and help heal wounds.
