Answer:
It has 3 main functions
1.Sensory. The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions.
2.Integration. The process of integration is the processing of the many sensory signals that are passed into the central nervous system at any given time. These signals are evaluated, compared, used for decision making, discarded or committed to memory as deemed appropriate.
3.Motor. Sends a signal to the Corresponding effector then releases a hormone or moves a part of the body to respond to the stimulus.

ii) It carries blood from the heart to different parts of the body.
iii) On regulatory demand of the body it can dilate or constrict.
iv) It doesn't contain any valve.
v) All arteries carry oxygenated blood except the pulmonary artery.
2)Vein ---
i) It is a blood vessel having a thin wall.
ii) It brings blood from different parts to the heart.
iii) It can't dilate or constrict under normal conditions.
iv) It contains valves that allow the blood to flow in one direction towards the heart.
v) All veins carry deoxygenated blood except the pulmonary vein.
3)Capillary ---
i) It is a very narrow blood vessel that has very thin walls.
ii) It forms a network throughout the body in all living cells connecting arteries to veins.
iii) It can dilate or constrict according to the requirement of tissue.
iv) It doesn't have any valve.
v) It contains mixed blood as it connects arteries and veins
