Question

In the circulatory system, which pathway accurately represents the route of deoxygenated blood and its return after picking up oxygen?

A) Right Ventricle (RV) to lungs, then Left Atrium (LA)
B) Left Ventricle (LV) to lungs, then Right Atrium (RA)
C) Right Atrium (RA) to body, then Left Ventricle (LV)
D) Left Atrium (LA) to body, then Right Ventricle (RV)

Answer 1

Deoxygenated blood travels from the Right Atrium to the Right Ventricle, to the lungs for oxygenation, and then oxygen-rich blood returns to the Left Atrium followed by the Left Ventricle.

Step-by-step explanation:

The Pathway of Deoxygenated Blood in the Circulatory System

The correct pathway for the circulation of deoxygenated blood picking up oxygen and returning it to the circulatory system is from the Right Atrium (RA) to the Right Ventricle (RV), then to the lungs for oxygenation. After gathering oxygen in the lungs and releasing carbon dioxide, the now oxygen-rich blood is transported to the Left Atrium (LA) and then moves into the Left Ventricle (LV), where it is pumped into the systemic circulation to supply the body with oxygenated blood. Therefore, the correct pathway is represented in option A) Right Ventricle (RV) to lungs, then Left Atrium (LA).
