Tunica adventitia (externa)

Question 16

What layer is usually much thinner in veins?

Answer 16

tunica media

Question 17

Answer 17

valves

Question 18

The tunica media is the layer that contains _______ muscle.

Answer 18

smooth

Question 19

What has more collagen, veins or arteries?

Answer 19

arteries (a lot more)

Question 20

Are the blood vessels on the surface of the body veins or arteries?

Answer 20

veins

*arteries are deep

Question 21

The arteries lead blood to the smallest _________, which lead to _________.

Answer 21

arterioles

capillaries

Question 22

How does gas transfer happen?

Answer 22

The RBCs have to march “single file” which makes their surfaces RIGHT UP against the wall of the vessel; so close to the tissue, the oxygen diffuses from the hemoglobin off the RBC to the tissue.

Question 23

After gas exchange in the capillaries, the blood goes to the smallest ________.

Answer 23

venules

Answer 24

RBCs and blood vessels

Question 25

RBCs come from the bone, but when don’t they?

Answer 25

in the embryo when they form the angiogenetic cell clusters

Answer 26

above the head

Distinction of the foregut and midgut
Heart placement on ventral part of body
The vagus nerve direction change

Question 28

What is responsible for the distinction of the midgut and hindgut?

Answer 28

Tail fold

Question 29

The “tube” leading out of the heart is called the

Answer 29

ventral aorta
