Myocardium
Epicardium

Question 8

The pulmonary circuit takes what kind of blood and carries it where?

Answer 8

Takes deoxygenated blood from the right side of the heart to lungs

Question 9

The systemic circuit?

Answer 9

takes oxygenated blood and pumps from left side of heart to everywhere in the body

Question 10

Where are arteries located?

Answer 10

In a position to avoid any damage due to the amount of blood contained

Continuous
fenestrated
sinusoidal

Question 13

3 ways to drain

deep veins
superficial veins
lymphatics

Question 14

Deep sit next to?

Answer 14

Supply arterial path and will typically have the same name as the supply artery

Question 15

Features of superficial veins?

Answer 15

Low pressure and low velocity so it is easy for blood to clot and seal itself
