Study Notes
Pericardium and Heart Structure
- The pericardium is a double-layered membrane that covers the heart, consisting of a fibrous outer layer and a serous inner layer.
- The fibrous pericardium is a tough, outer layer that protects the heart and anchors it to surrounding structures.
- The serous pericardium is a thin, inner layer that secretes pericardial fluid to reduce friction between the heart and surrounding tissues.
Functions of the Cardiovascular System
- The cardiovascular system plays a crucial role in transporting oxygen and nutrients from the lungs and digestive system to the body's cells.
- It also removes waste products, such as carbon dioxide, from the body's cells.
- The cardiovascular system regulates body temperature, maintains pH balance, and provides immune function.
Heart Location and Structure
- The apex of the heart is located at the bottom of the heart, pointing downwards towards the left lung.
- The adult heart is approximately 250-300 grams in weight, which is about the size of a fist.
- The heart is a cone-shaped, muscular organ that pumps blood throughout the body.
