Heart Anatomy PART 1 Study Guide

front 1

What is the size, location and orientation of the heart?

3. Base is directed toward the right shoulder and the apex points towards the left hip.

What are the Coverings of the Heart?

back 2

1. THE HEART IS ENCLOSED IN A DOUBLED-WALLED SAC CALLED THE PERICARDIUM.

2. DEEP TO THE PERICARDIUM IS THE SEROUS PERICARDIUM.

3.THE PARIETAL PERICARDIUM LINES THE INSIDE OF THE PERICARDIUM.

4. THE VISCERAL PERICARDIUM, OR EPICARDIUM, COVERS THE SURFACE OF THE HEART.

HEART VALVES?

back 7

1. THE TRICUSPID AND MITRAL VALVES PREVENT BACKFLOW INTO THE ATRIA WHEN THE VENTRICLES CONTRACT.

2. WHEN THE HEART IS RELAXED THE AV VALVES ARE OPEN, AND WHEN THE HEART CONTRACTS THE AV VALVES CLOSE.

3. THE AORTIC AND PULMONARY VALVES ARE FOUND IN THE MAJOR ARTERIES LEAVING THE HEART. THEY PREVENT BACKFLOW OF BLOOD INTO THE VENTRICLES.

4. WHEN THE HEART IS RELAXED THE AORTIC AND PULMONARY VALVES ARE CLOSED, AND WHEN THE HEART CONTRACTS THEY ARE OPEN.
