Blood flow
horrorfan [7]

Answer:

D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation

Explanation:

The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.

The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).

The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).

From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.

Thus, Option-D is correct.

These frogs are most easily recognized by their feet, which have claw-shaped toe bones as their last bone. They can also climb trees thanks to toe pads with small suction cups and extraskeletal structures on their toes. They are available in a number of hues, the most popular being green, gray, or brown.
