1. The lining of a capillary is called: ______

2. Arteries are more ______have than veins, and veins __________which arteries do not.
3. Special capillaries that supply nutrients to the walls of arteries and veins are called:___
4. The deposition of plaques in artery walls is called _______
5. Renal arteries supply blood to the ________
6. The longest vein in the body is __________
7. If someone's blood pressure is 120/80 which is the diastolic number?
8. If someone has a blood pressure reading of 110/70 mm Hg, their pulse pressure would be __________-
9. The viscosity of blood is influenced largely by , __________which is the percentage of the total blood volume composed of red blood cells.

Answer 1

The lining of a capillary is called endothelium. Arteries are more muscular and elastic than veins, and veins have valves which arteries do not. Special capillaries that supply nutrients to the walls of arteries and veins are called vasa vasorum.

Step-by-step explanation:

1. The lining of a capillary is called endothelium.

2. Arteries are more muscular and elastic than veins, and veins have valves which arteries do not.

3. Special capillaries that supply nutrients to the walls of arteries and veins are called vasa vasorum.

4. The deposition of plaques in artery walls is called atherosclerosis.

5. Renal arteries supply blood to the kidneys.

6. The longest vein in the body is the great saphenous vein.

7. If someone's blood pressure is 120/80, the diastolic number is 80.

8. If someone has a blood pressure reading of 110/70 mm Hg, their pulse pressure would be 40 mm Hg.

9. The viscosity of blood is influenced largely by hematocrit, which is the percentage of the total blood volume composed of red blood cells.

The lining of a capillary is called the endothelium. Arteries are more thick-walled than veins, and veins have valves which arteries do not. Special capillaries that supply nutrients to the walls of arteries and veins are called vasa vasorum. The deposition of plaques in artery walls is called atherosclerosis. Renal arteries supply blood to the kidneys. The longest vein in the body is the great saphenous vein. If someone's blood pressure is 120/80, the diastolic number is 80. If someone has a blood pressure reading of 110/70 mm Hg, their pulse pressure would be 40 mm Hg (110 - 70). The viscosity of blood is influenced largely by hematocrit, which is the percentage of the total blood volume composed of red blood cells.
