Name the 2 layers of the fibrous pericardium:

  1. Fibrous 
  2. Parietal periocardium

 

2

A covering of the heart composed of dense connective tissue, composes the outermost layer of the fibrous pericardium, and attaches to the diaphragm?

Fibrous layer

3

A heart covering composed of a serous membrane and lines the fibrous sac?

Parietal pericardium

4

Name three layers of the heart:

  1. Epicardium (AKA visceral pericardium)
  2. Myocardium
  3. Endocardium

5

The ___________ is the serous membrain that covers the surface of the heart?

Epicardium

6

_________ is the thick cardia muscle?

Myocardium

7

__________ is the serous inner lining of the heart?

Endocardium

8

_______ are the upper recieving chambers of the heart?

Atria

9

_______ are the lower pumping chambers of the heart?

ventricles

10

What is the purpouse of valves in the heart?

To prevent backflow.

11

Name the 4 valves in the heart in the order in which blood flows through them:

  1. Right Atrioventricular (AV) valve
  2. Tricuspid valve
  3. Left Atrioventricular (AV) valve

12

___________ are fibrous cords that attach AV valves to papillary muscle.

Chordae Tendinae

13

The Chordae tendinae attach to what muscle?

papillary muscle

14

Name the 2 semilunar valves that seporate the ventricles from the arteries:

  1. Pulmonary Semilunar valve
