Correct Answer
A. ValveExplanation
A small door-like flap in the heart that regulates blood flow is called a valve. Valves are essential components of the heart that ensure blood flows in the correct direction through the heart's chambers and to the rest of the body. There are four main valves in the heart: the aortic valve, the mitral valve, the pulmonary valve, and the tricuspid valve. These valves open and close in response to pressure changes within the heart, preventing the backflow of blood and maintaining efficient circulation.Rate this question:

What are the two large veins that enter the heart?
- A.
Pulmonary veins and Pulmonary artery
- B.
Superior vena cava and Inferior vena cava
- C.
Aorta and Superior vena cava
- D.
Inferior vena cava and Coronary sinus
Correct Answer
B. Superior vena cava and Inferior vena cavaExplanation
The two large veins that enter the heart, the superior vena cava and the inferior vena cava, are essential for returning deoxygenated blood to the right atrium. The superior vena cava carries blood from the upper body, including the head, neck, arms, and upper torso, while the inferior vena cava carries blood from the lower body, including the legs, abdomen, and pelvis. Once the deoxygenated blood reaches the right atrium, it is pumped into the right ventricle and then sent to the lungs for reoxygenation via the pulmonary arteries. The oxygenated blood then returns to the left atrium and is circulated throughout the body, ensuring the delivery of oxygen and nutrients to tissues and the removal of metabolic waste.Rate this question:
