Explanation / Answer

Circulation and red blood cells

1.venous pump- (G) The leg muscle push the blood towards heart while walking.

2. Venous valves-(a) prevent blood from pooling under gravitational blood pressure.

3. Resistance- (e) increases with increased blood visvosity

5.systemic arteries-(D) transport blood under high pressure to tissues.

6. Hemoglobin-(F) composed of iron atoms that binds and carry molecular oxygen

7.Erthrocytes-(I) having a biconcave shape with reversible deformity.

8.Veins-(J) have muscular wall used to direct local blood flow

9.Laminar flow-(c) parabolic profile of blood flow

10 Distensibility-(H) ability of all blood vessel to expand under pressure

11. Reticulocytes-(K) form of red cells that enter circulation from bone marrow.

12. Spleen-(L) filter dying red blood cells from circulation and also blood reservoir
