QUESTION 13

1. The DIAMETER OF THE LUMEN of a blood vessel affects the flow rate of blood passing through it.

   True

   False

Answer 1

7-1)Elastic arteries

2)muscular arteries

3)arterioles

Elastic arteries is the largest one which is near the heart. It is subdivided into smaller branches called muscular arteries. Muscular arteries are eventually divided into arterioles.

8-1)Elastic arteries

2)Muscular arteries

3)Aterioles

4)Capillary

5)Venules

6)Veins

Blood travels from heart through elastic arteries then enters into muscular arteries. Then blood is carried to arterioles which divides into fine capillaries. Here exchange of blood takes place through vessels and then blood enters into venule and then into veins. This blood enters into heart.

9)True. In this system the blood does not enter the heart and it is directly passed on from artery to vein.

10-D)Colloid osmotic pressure

11-True

12-True. If the blood vessel thickness increses, the blood pressure increases and blood flow is reduced because of vasoconstriction.

13-True. If diameter of lumen decreases the flow rate of blood is reduced and pressure is increased.
