Circulatory System Part - 1 Video Lecture | Biology Class 11 - NEET

1. What are the main components of the circulatory system?$#

Ans. The main components of the circulatory system include the heart, blood vessels (arteries, veins, and capillaries), and blood.

2. How does the circulatory system function in the human body?$#

Ans. The circulatory system functions by pumping oxygen-rich blood from the heart to the rest of the body through arteries, exchanging gases and nutrients in capillaries, and returning deoxygenated blood back to the heart through veins.

3. What is the role of red blood cells in the circulatory system?$#

Ans. Red blood cells, or erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues and organs, while also transporting carbon dioxide back to the lungs to be exhaled.

4. How does the circulatory system help regulate body temperature?$#

Ans. The circulatory system helps regulate body temperature by redistributing heat throughout the body. Blood vessels near the skin can dilate to release heat, or constrict to conserve heat, depending on the body's needs.

5. What are some common circulatory system disorders?$#

Ans. Common circulatory system disorders include hypertension (high blood pressure), atherosclerosis (hardening of the arteries), and peripheral artery disease (reduced blood flow to the limbs).
