Answer 1

Answer:

1.The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

2.The atrium (Latin ātrium, “entry hall”) is the upper chamber through which blood enters the ventricles of the heart. There are two atria in the human heart – the left atrium receives blood from the pulmonary (lung) circulation, and the right atrium receives blood from the venae cavae (venous circulation). The atria receive blood while relaxed (diastole), then contract (systole) to move blood to the ventricles. All animals with a closed circulatory system have at least one atrium. Humans have two atria.

3.The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs for oxygenation. The pulmonary veins carry oxygenated blood from the lungs into the left atrium where it is returned to systemic circulation. The aorta is the largest artery in the body.

4.One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas, veins carry the deoxygenated blood to the heart.

Difference Between Arteries and Veins.

ARTERIES VEINS

Arteries are red in colour. Veins are blue in colour.

5.Tricuspid valve is located between the right auricle and the right ventricle. ... Aortic valve is located between the left ventricle and the aorta. So, the correct answer is 'Mitral valve'.

6.Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale.

7.The aorta is the largest artery in the body. It carries oxygenated blood from the left ventricle of the heart into systemic circulation.

8.The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.
