Which chambers of the heart receive oxygenated blood?

Right atrium and right ventricle
Right atrium and left ventricle
Left atrium and left ventricle
Both atriums

The correct answer is: Left atrium and left ventricle

The chambers of the heart that receive oxygenated blood are the left atrium and the left ventricle. The left atrium receives oxygen-rich blood from the lungs through the pulmonary veins. Once this oxygenated blood fills the left atrium, it flows into the left ventricle, which is responsible for pumping it out to the rest of the body through the aorta. This process is crucial for supplying oxygen to the body’s tissues, supporting metabolic functions and overall health. The other chambers, namely the right atrium and right ventricle, handle deoxygenated blood. The right atrium collects blood returning from the body that lacks oxygen, and the right ventricle pumps this blood to the lungs for oxygenation. Understanding the flow of oxygenated and deoxygenated blood through the heart is vital for recognizing the cardiovascular system's function in maintaining physiological homeostasis.
