What is the name of the lower, thick-walled chamber of the heart?

• A. Atrium
• B. Ventricle
• C. Aorta
• D. Vein

Answer: (B)

The lower, thick-walled chamber of the heart is known as the ventricle. The heart comprises four chambers: two atria (upper chambers) and two ventricles (lower chambers). Ventricles have thicker walls compared to atria because they are responsible for pumping blood out of the heart to the lungs and the rest of the body, which requires more force. The left ventricle, in particular, has the thickest wall as it pumps oxygenated blood to the entire body. Understanding the structure and function of the heart's chambers is crucial for recognizing how blood circulation operates in the human body.
