  1. Circulatory System Review

  2. plasma Which part of the human blood: • carries carbon dioxide, nutrients, wastes, vitamins, minerals, hormones and enzymes? • carries oxygen and carbon dioxide? • is involved in blood clotting? • helps fight disease? • contains hemoglobin? • is the liquid portion of the blood? rbc’s platelets wbc’s rbc’s plasma

  3. rbc’s wbc’s Which part of the human blood: • is the most numerous? • contains a nucleus? • is biconcave? • is produced in the bone marrow? • consists mainly of water? rbc’s rbc’s, wbc’s, platelets plasma

  4. white blood cell Y Z red blood cell platelet Identify structures X, Y, and Z.

  5. Which activity is NOT a function of white blood cells in response to an invasion of the body by bacteria? engulfing these bacteria producing antibodies to act against this type of bacteria preparing for future invasions of this type of bacteria speeding transmissions of nerve impulses to detect these bacteria

  6. Which part of the human blood transports hormones and nutrients? plasma platelets red blood cells white blood cells

  7. The breaking apart of platelets in the blood helps in the synthesis of hemoglobin formation of a clot release of antibodies deamination of amino acids

  8. Cardiovascular diseases interfere most directly with the normal functioning of system?

  9. Explain the difference between arteries and veins. • Arteries carry blood AWAY from heart. Veins carry blood to the heart. • Arteries are larger, more muscular and elastic than veins. • Arteries carry blood under higher pressure than veins. • Veins have valves to prevent the backflow of blood. Arteries do not have valves.

  10. The exchange or diffusion of substances into or out of the capillary. Explain what occurs in capillaries and why. Capillaries are extremely small and have a VERY thin lining that allows for diffusion to occur.

  11. glucose O2 CO2 O2 glucose glucose O2 CO2 The diagram represents a capillary near some cells. 1. Identify the substances diffusing out of the capillary and into cells. 2. Identify the substances diffusing out of cells into the capillary. CO2 O2 glucose

  12. Blood normally flows from the capillaries directly into small arteries small veins 3. lymph vessels 4. heart atria

  13. The movement of blood from the legs toward the heart is hindered by gravity. The effect of gravity is counteracted by smooth muscle in the capillaries cilia lining the blood vessels valves in the veins lymph nodes near major vessels

  14. Which statement best describes arteries? They have thick walls and transport blood away from the heart. They have thick walls and transport blood toward the heart. They have thin walls and transport blood away from the heart. They have thin walls and transport blood toward the heart.

  15. Identify the upper chambers of the heart. Identify the lower chambers of the heart. Identify the structures that separate the upper and lower chambers. Identify the wall that separates the right and left side of the heart. Right and left atria Right and left ventricles valves septum

  16. Identify structures B, D, E, F and H. aorta left atrium right atrium left ventricle right ventricle

  17. valve When blood passes through the heart from the left atrium (D) to the left ventricle (E), it must first pass through a

  18. Identify the part of the heart being described. • Chamber that receives oxygenated blood. • Wall that separates the right and left side of the heart. • Large artery that carries oxygenated blood to the rest of the body. • Chamber that pumps out deoxygenated blood. Left atrium Septum Aorta Right ventricle

  19. Right atrium 5. Chamber that receives deoxygenated blood. 6. Prevents the backflow of blood between atria and ventricles. 7. Chamber that pumps out oxygenated blood. Valves Left ventricle

  20. For blood to pass through the heart from the left atrium to the left ventricle, it must first pass through an artery a valve a vein a capillary

  21. Blood in the right ventricle will be pumped to the brain small intestine kidneys lungs

  22. Blood in the left atrium will move to the brain Lungs left ventricle right ventricle

  23. What is a major difference between red blood cells and white blood cells? Red blood cells contain hemoglobin, but white blood cells do not. Red blood cells can move, but white blood cells cannot. Red blood cells contain nuclei, but white blood cells do not. Red blood cells engulf foreign bacteria, but white blood cells do not.

  24. What component of blood is important in healing wounds on the skin?   red blood cells   urea   platelets   white blood cells

  25. Where are red and white blood cells made in the body? in lymph nodes   in bone marrow   at the sinoatrial node   in the heart

  26. What component of blood plays a role in protection against disease?   white blood cells   platelets   urea   red blood cells

  27. Which blood component is a liquid?    platelets   white blood cells   plasma   red blood cells
