Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

____ always returns blood to the heart.

A	Veins
B	Arteries
C	Capillaries
D	None of the above

Explanation:

Detailed explanation-1: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.

Detailed explanation-2: -Arteries transport blood from the heart to the body tissues. Veins carry blood back to the heart.

Detailed explanation-3: -Your aorta and pulmonary trunk (arteries) send blood out of your heart. Your pulmonary veins, superior vena cava and inferior vena cava (veins) carry blood into your heart.

Detailed explanation-4: -Blood flows through a network of vessels called the circulatory system. When blood returns to your heart, it flows to your lungs to receive oxygen. Then your heart pumps that blood out to the rest of your body, and the process begins again.
