Which blood vessels have the smallest diameter?

  1. Capillaries

  2. Arterioles

  3. Venules

  4. Lymphatic

Correct Option: A

A vein differ from an artery in having

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. Strong muscular walls

  2. Narrow lumen

  3. Valves that control direction of blood flow opposite to heart

  4. Valves that control direction of blood flow towards heart

Show answer
Correct Option: C
Explanation:

Veins drain capillaries in the tissues and organs and return the blood to the heart. Veins have a unique structural feature which is not present in arteries. They are equipped with one way valves, that prevent the back flow of blood.

In which of the following character a vein differs from an artery?

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. Having valves to control flow of blood

  2. Having narrow lumen

  3. Having muscular wall

  4. Having pigmented wall to give dark look

Show answer
Correct Option: A
Explanation:

Arteries carry blood from the ventricles (pumping chambers) of the heart out to the capillaries in organs and tissue. The smallest arteries are called arterioles.Veins drain capillaries in the tissues and organs and return the blood to the heart. The smallest veins are the venules.
Veins have a unique structural feature not present in arteries. They are equipped with one-way valves that prevent the backflow of blood.

So, the correct answer is option A.

An artery can be distinguished from a vein in having

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. Thicker wall

  2. Oxygenated blood

  3. More haemoglobin

  4. Both A and B

Show answer
Correct Option: D
Explanation:
  • An artery carries oxygenated blood from the heart to different parts of the body. It has thick walls that allow it to withstand the high pressure of the blood.
  • Veins carry the deoxygenated blood from the different parts of the body to the heart which is further carried by the pulmonary artery for oxygenation. The veins have thin and elastic walls.
So, the correct answer is option D.

Arteries are the

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. Blood vessels which carry only oxygenated blood

  2. Blood vessels which carry only deoxygenated blood

  3. Blood vessels which carry blood from the heart to different organs of the body

  4. Blood vessels which carry blood from different organs of the body to the heart

Show answer
Correct Option: C
Explanation:
Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well.
So, the correct option is 'Blood vessels which carry blood from the heart to different organs of the body'.
