Answer 1

Answer:

1,

Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

2,

Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.

Veins are vessels of the circulatory system that support circulation by conveying blood to the heart. Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body.

Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.

Answer 2

Answer :-

1. What is pulmonary circulation ?

Ans. Pulmonary circulation, system of blood vessels that forms a closed circuit between the heart and the lungs, as distinguished from the systemic circulation between the heart and all other body tissues. ... In the capillaries the blood takes up oxygen from the air breathed into the air sacs and releases carbon dioxide.

2. Explain the functions of artery, vein and capillaries.

Ans. Arteries :-

• Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs.
• Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.

Veins :-

• Veins are a type of blood vessel that return deoxygenated blood from your organs back to your heart.
• These are different from your arteries, which deliver oxygenated blood from your heart to the rest of your body.
• Deoxygenated blood that flows into your veins is collected within tiny blood vessels called capillaries.

Capillaries :-

• Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
• The primary function of capillaries is the exchange of materials between the blood and tissue cells.
