Question

Arteries are best defined as the vessels which
(a) Carry blood from one visceral organ to another visceral organ.
(b) Supply blood to the different organs.
(c) Break up into capillaries that reunite to form a vein.
(d) Both (a) and (c)
(e) none

Answer 1

Hint: Blood vessels are part of the circulatory system and they help in the transport of blood throughout the body. There exist three types of blood vessels: arteries, veins, and capillaries.

Complete answer:
The arteries are the blood vessels that transport oxygenated blood from the left ventricle to the organs. It also transports deoxygenated blood from the right ventricle to the lungs.
 When an artery reaches a particular tissue or organ it divides into thinner capillaries to distribute its content through diffusion across the thin wall.
After diffusion, they carry away carbon dioxide and other nitrogenous waste from the tissue and merge to form veins.

Presentation of transport and exchange of oxygen and carbon dioxide

So, the correct answer is arteries are best defined as the vessel which carries blood from one visceral organ to another visceral organ and breaks into capillaries which reunite to form a vein.

Note:
1. Capillaries are a thin network of blood vessels that are just one-celled thick and semipermeable.
2. Visceral organs: These are soft organs located within the three central cavities of the body: the chest, the abdomen, and the pelvis. e.g., heart, lungs, stomach, liver, etc.
3. Arterioles are the smallest arteries and venules are the smallest veins.
4. The capillaries connect the arterioles and venules.
5. Capillaries allow for exchanges between the blood and body cells, and also between the blood and air in the lung tissues.
