Circulatory system of man is made up of which muscle
a)smooth
b)cardiac
c)skeletal

In the human body, the circulatory systems are made up of smooth muscle.

Option (a);

EXPLANATION:

The circulatory system of a body helps to transfer nutrients and oxygen from the small intestine and the lungs respectively to the cells of the body.

This reduces the waste content from the human body.

The blood vessels of the circulatory system are made up of smooth muscle tissue.

The smooth muscle cells around the blood vessels help to regulate the blood flow to the different segments of the body.

It helps to change the diameter of the arteries.

When the arteries constrict, it reduces the space for blood to flow increasing the blood pressure.

typically, most spiders possess eight eyes. however, others have as many as 12, and some don't have any. these eyes are for detecting light from dark, deciphering shapes and for gathering their prey.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
