Understanding the Human Cardiovascular System and Blood
The Cardiovascular System: Heart and Blood
The heart is the pump that moves blood through the cardiovascular system. It consists of two halves separated by a muscular wall.
Structure of the Heart
Each half of the heart is divided into an upper and lower cavity. The heart is enclosed in the pericardium, a double sac that provides a fluid-filled space for it to beat freely.
- Myocardium: Muscle tissue that forms the heart wall.
- Atria: The upper chambers of the heart.
- Ventricles: The heart’s lower chambers.
