Problem #1

_____(1)_______ occurs when the blood pressure remains consistently high. This condition can occur without any specific known cause, in which case it is referred to as _____(2)______. This condition can also be the side effect of another, known condition, in which case it is referred to as _______(3)__________.

(1) choices:

a. Hypertension

b. Hypotension

(2) choices:

a. primary hypotension

b. secondary hypertension

c. primary hypertension

d. secondary hypotension

(3) choices:

a. primary hypotension

b. secondary hypotension

c. primary hypertension

d. secondary hypertension

Problem #2

If the body is normally able to regulate MAP in the body, then why does consistent high blood pressure occur?

A. Over time, the baroreceptors deactivate completely after exposure to continuous high pressure, which means the body must rely on slower, long-term control mechanisms.

B. Over time, the baroreceptors that monitor pressure become desensitized from continuous high pressure, which reduces their regulating activity.

C. Over time, the baroreceptors that monitor pressure become oversensitized from continuous high pressure, which increases their regulating activity.

Question: Which of the following statements describe ways that materials pass between the blood and the tissues of the body through capillaries? Check all that apply.

A. Passing directly through the endothelial cells of the capillary walls through diffusion.

B. Passing directly through the endothelial cells of the capillary walls through active transport

C. Passing through pores between the endothelial cells of the capillary walls.

a) Areas B and A have roughly equivalent flow velocities, but Area C has a lower flow velocity.

b) Flow velocity decreases steadily as the blood moves from Area B to Area C to Area A.

c) Areas B and A have roughly equivalent flow velocities, but Area C has a higher flow velocity.

d) Flow velocity increases steadily as the blood moves from Area B to Area C to Area A.

Lymph vessels are vessels that are separate from the circulatory system but are closely associated with capillary beds. Which one of the following statements correctly describes the role that lymph vessels play in bulk flow?

a) Lymph vessels actively pump proteins into the interstitial fluid to create the diffusion gradients that power bulk flow.

b) Lymph vessels absorb extra fluid from the interstitial fluid that is not returned to the blood through the capillaries via bulk flow.

c) Lymph vessels secrete extra fluid into the interstitial fluid to encourage the pressure gradients that power bulk flow.

Explanation / Answer

__HYPERTENSION__ occurs when the blood pressure remains consistently high. This condition can occur without any specific known cause, in which case it is referred to as ___primary hypertension___. This condition can also be the side effect of another, known condition, in which case it is referred to as __secondary hypertension___.

PROBLEM #2

B. Over time, the baroreceptors that monitor pressure become desensitized to continuous high pressure, which reduces their regulating activity.

PROBLEM #3

Question: Which of the following statements describe ways that materials pass between the blood and the tissues of the body through capillaries? Check all that apply.

ANSWER:

A. Passing directly through the endothelial cells of the capillary walls through diffusion.

C. Passing through pores between the endothelial cells of the capillary walls.

PROBLEM #4

In the preceding diagram, three areas of the vessels system are highlighted by boxes labelled A, B, and C.Which one of the following statements correctly describes how flow velocity differs among these three areas?

ANSWER:

a) Areas B and A have roughly equivalent flow velocities, but Area C has a lower flow velocity.

b) Flow velocity decreases steadily as the blood moves from Area B to Area C to Area A.

PROBLEM #5

Lymph vessels are vessels that are separate from the circulatory system but are closely associated with capillary beds. Which one of the following statements correctly describes the role that lymph vessels play in bulk flow?

b) Lymph vessels absorb extra fluid from the interstitial fluid that is not returned to the blood through the capillaries via bulk flow.

c) Lymph vessels secrete extra fluid into the interstitial fluid to encourage the pressure gradients that power bulk flow.
