Answer 1

<60mmHg

Question 2

What is degree of vascularization?

Answer 2

Extent of vessels in a tissue

Question 3

What is angiogenesis?

Answer 3

Formation of new vessels

Question 4

What is regression?

Answer 4

Return to previous state of blood vessels

Question 5

What is myogenic response?

Answer 5

Smooth muscle in blood vessel wall keeps local flow relatively constant

Question 6

If systemic blood pressure rise and more blood enters an arteriole it will?

Answer 6

Stretch and contract to return to original levels

Question 7

If systemic blood pressure decreases and amount of blood decreases, there will be?

Answer 7

Less stretch and relax to return to original levels

Question 8

What is vasoactive chemicals?

Answer 8

Alter blood flow through vessels

Question 9

What is autoregulation?

Answer 9

Changing metabolic activity by which tissue controls local blood flow

Question 10

What is inflammation?

Answer 10

Damaged tissue, leukocytes, and platelets release vasoactive chemicals

80 mmHg and relaxed

Question 13

What is blood pressure?

Answer 13

Force of blood against vessel wall

Question 14

What is blood pressure gradient?

Answer 14

Change in pressure from one end of vessel to other

Question 15

Pulse pressure reflects

Answer 15

The elasticity and recoil of arteries
