Study Notes
Cardiovascular System
- The system consists of the heart and blood vessels.
Components of the Cardiovascular System
- Blood vessels: arteries, veins, capillaries.
- Arteries carry blood away from the heart.
- Veins return blood to the heart.
- Capillaries connect arteries and veins.
Role of the Heart
- The heart pumps blood throughout the body.
- It facilitates blood flow through a network of blood vessels.
The Structure of the Heart
- The heart has four chambers.
- Right atrium: Receives blood from the body except the lungs.
- Right ventricle: Receives blood from the right atrium and pumps it to the lungs.
- Left atrium: Receives oxygen-rich blood from the lungs.
- Left ventricle: Pumps blood out to the body via the aorta.
Apex of the Heart
- The lower tip of the heart.
Heart Septum
- Interatrial septum: Separates the right and left atria.
- Interventricular septum: Separates the right and left ventricles.
The Heart Layers
- Endocardium: The innermost layer.
- Myocardium: The middle and thickest layer, composed of muscle tissue.
- Epicardium: The outermost layer.
- Pericardium: A sac that surrounds the heart.
Blood Flow and Circuits
- Pulmonary Circuit: Blood movement from the right ventricle to the lungs via pulmonary arteries and back to the left atrium through pulmonary veins.
- Systemic Circuit: Circulation of blood through the arteries, capillaries, and veins of the body.
