Question

Which of the following statements is true?

Blood in the heart only flows one-way.
The heart is the largest organ in the body.
The ventricles receive blood from the body.
The atria pump oxygen-rich blood to the body.

Answer 1

Answer is D

Step-by-step explanation:

As the heart pumps blood, a series of valves open and close tightly. These valves ensure that blood flows in only one direction, preventing backflow. The tricuspid valve is situated between the right atrium and right ventricle. The pulmonary valve is between the right ventricle and the pulmonary artery.
