Question
Chapter 21.5, Problem 20BYGO
Summary Introduction
To analyze:
The two changes that occur in the blood vessels in old age, other than specific vascular diseases.
Introduction:
Our arteries become less distensible as we get older and absorb lea systolic strength. This growing rigidity is referred to as arteriosclerosis. The primary cause of this is a lifeline of free radicals damage that causes the elastic and other tissues of the arterial walls to deteriorate gradually. Another contributing factor is atherosclerosis, the growth of lipid deposits in the arterial walls. The most common vascular disease, atherosclerosis, can lead to stroke, kidney failure, or heart failure.

This is Anatomy and Physiology II related questions. More specifically on blood vessels. Please help me answer these questions, thank you :)
List all the blood vessels a blood cell from the left fibula vein would have to go through to arrive in the right ulnar artery. There is no left brachiocephalic artery. How does the anatomy of the left side of the body differ from the right in this region? What type of tissue creates a valve? A piece of the great saphenous vein is removed from the leg and used to bypass clots that form in the arteries that supply the heart muscle. Why doesn't the leg suffer from the removal of a piece of this vein?

Illuminate the Truth Capillaries
Highlight the word or phrase that makes cach of the following statements true.
1. Capillaries (are)(are not) evenly distributed throughout the body.
2. The majority of the capillaries in skeletal muscles are (constantly filled with blood)(shut down during periods
of rest).
3. Capillaries (take up)(release) wastes, such as carbon dioxide and ammonia.
4. Water (flows into)(moves into and out of) capillaries.
5. In diffusion, substances move from areas of (greater)(lesser) to (greater)(lesser) concentration.
6. The concentration of oxygen within capillaries is (greater than)(less than) the concentration of oxygen in the
surrounding tissue fluid; therefore, oxygen diffuses (into)(out of) the capillaries.
7. (Osmosis) (Filtration) occurs close to the arterial side of the capillary bed, while (colloid osmotic
pressure)(diffusion) operates toward the venous side.
8. Of all the fluid filtered at the arterial end of the capillary bed. about (85%)(15%) is…
