Circulatory System Review

Which part of the human blood: 1.carries carbon dioxide, nutrients, wastes, vitamins, minerals, hormones and enzymes? 2.carries oxygen and carbon dioxide? 3.is involved in blood clotting? 4.helps fight disease? 5.contains hemoglobin? 6.is the liquid portion of the blood? plasma rbc’s platelets wbc’s rbc’s plasma

Which part of the human blood: 1.is the most numerous? 2.contains a nucleus? 3.is biconcave? 4.is produced in the bone marrow? 5.consists mainly of water? wbc’s rbc’s rbc’s, wbc’s, platelets rbc’s plasma

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

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.

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

Identify the part of the heart being described. 1.Receives oxygenated blood. 2.Wall that separates the right and left side of the heart. 3.Large artery that carries oxygenated blood to the rest of the body. 4.Veins that carry oxygenated blood from the lungs back to the heart. 5.Pumps out deoxygenated blood. Left atrium Septum Aorta Pulmonary veins Right ventricle

6. Receives deoxygenated blood. 7. Prevents the backflow of blood between atria and ventricles. 8. Pulps out oxygenated blood. 9. Veins that carry deoxygenated blood back to the heart. 10. Arteries that carry oxygenated blood to the lungs. Right atrium Valves Left ventricle Vena cava Pulmonary arteries

Blood TypeAntigensAntibodies A B AB O Fill in the table below with the correct antigens and antibodies for each blood type. antigen A antigen B antigen A and antigen B none anti-B antibodies anti-A antibodies none Both anti-A and anti-B antibodies

What makes blood type O the universal donor? Type O blood does not have any antigens, so they can be given to any blood type.

What makes blood type AB the universal recipient? Type AB blood has both A and B antigens, so they can receive any blood type.

Which of the blood types in the ABO system may safely be given to a person with AB blood? 1.O or AB, only 2.A or B, only 3.B or AB, only 4.A, B, AB, or O
