MV Human Heart Medical Cardiovascular 3D Model
The human heart is a vital organ that functions as the central component of the circulatory system. Here are some key aspects:
Anatomy
- Size and Location: The heart is roughly the size of a closed fist and is located between the lungs in the mediastinum, slightly to the left.
- Chambers: It consists of four chambers:
- Atria: Two upper chambers (left atrium and right atrium) that receive blood.
- Ventricles: Two lower chambers (left ventricle and right ventricle) that pump blood out of the heart.
- Valves: The heart has four main valves (tricuspid, pulmonary, mitral, and aortic) that ensure unidirectional blood flow.
Function
- Pumping Blood: The heart pumps oxygenated blood to the body and receives deoxygenated blood from the body.
- Circulation: Blood circulates through two main pathways:
- Systemic Circulation: Oxygen-rich blood is distributed to the body.
- Pulmonary Circulation: Deoxygenated blood is sent to the lungs for oxygenation.
Importance
- The heart is essential for delivering oxygen and nutrients to tissues and removing carbon dioxide and waste products.
