Solution
The correct option is C Heart → Artery → Arteriole → Capillary → Venule → Vein
Heart is a pumping organ which pumps blood throughout the body via a circulatory system supplying oxygen and nutrients to the tissues.
Arteries are the blood vessels which carry blood away from the heart to various tissues or organs of the body.
On reaching an tissue or organ, the artery divides into smaller and smaller vessels called arterioles and further branches to form capillaries to bring the blood in contact with all the individual cells.
Exchange of substances between blood and the surrounding cells takes place across the thin wall of capillaries.
The capillaries join together to form venules which further join to form veins.
Veins collect the blood from different organs and bring it back to the heart.
