Study Notes
Functions of the Cardiovascular System
- Primary role is to transport oxygen, nutrients, hormones, and waste products throughout the body.
- Essential for maintaining homeostasis and regulating temperature.
Structure and Orientation of the Heart
- The apex of the heart is directed downward, forward, and to the left.
- The base of the heart is oriented upward and backward, facing the right shoulder.
Pericardium and Its Functions
- The fibrous pericardium provides protection and anchors the heart in place, serving as a tough outer layer.
- The visceral pericardium, also known as the epicardium, acts as an inner layer that directly covers the heart.
Serous Fluid and Heart Function
- Serous fluid within the pericardial cavity reduces friction during heartbeats, allowing smoother movements of the heart.
- It facilitates the heart's expansion and contraction, contributing to effective mechanical function.
