The lower chambers of the heart are called ventricles.
The ventricles are the two lower chambers of the heart that are responsible for pumping blood to the rest of the body. They are larger and more muscular than the upper chambers of the heart, known as the atria.
Here are some key points about the ventricles:
- Location: The ventricles are located in the lower part of the heart, below the atria.
- Function: They receive blood from the atria and pump it out to the lungs and the rest of the body.
- Left Ventricle: The left ventricle is responsible for pumping oxygenated blood to the body's organs and tissues.
- Right Ventricle: The right ventricle pumps deoxygenated blood to the lungs to pick up oxygen.
- Valves: The ventricles are separated from the atria by valves, which ensure that blood flows in one direction.
- Contractions: The ventricles contract forcefully to pump blood out of the heart, creating the pulse.
- Blood Supply: The ventricles receive blood supply from the coronary arteries, which provide oxygen and nutrients to the heart muscle.
Overall, the ventricles play a crucial role in the circulatory system by pumping blood efficiently to meet the body's oxygen and nutrient needs.
