Match the heart chamber with the type of blood it handles: (A) Right atrium (B) Left ventricle (C) Left atrium (D) Right ventricle
A-De-oxygenated, B-Oxygen-rich, C-Oxygen-rich, D-De-oxygenated
In the normal double circulation of blood, the right atrium receives de-oxygenated blood from the body via the venae cavae; the right ventricle pumps this de-oxygenated blood to the lungs via the pulmonary artery.
The left atrium receives oxygen-rich blood returning from the lungs via the pulmonary veins, and the left ventricle pumps this oxygen-rich blood into the aorta for systemic circulation.
So A-De-oxygenated, B-Oxygen-rich, C-Oxygen-rich, D-De-oxygenated is the correct match.
Hence, A-De-oxygenated, B-Oxygen-rich, C-Oxygen-rich, D-De-oxygenated.
