Question

How many arteries are present in a human body?

Answer 1

Hint: Arteries are the blood vessels functioning within the cardiovascular system of the human body. It transports blood throughout the body, aiding to oxygenate and deoxygenate every cell with every heartbeat.

Complete answer:
The Blood vessels that carry the blood away from the heart are referred to as Arteries. The arteries are the blood vessels that deliver oxygen-rich blood (Oxygenated ) from the heart to the tissues and different parts of the body.

There are about 20 major arteries present throughout the human body. Arteries are tube-shaped and are divided into smaller branches called arterioles and capillaries. Aorta is the largest artery present in the left ventricle of the heart. Each artery is made up of muscular tissue and lined by Smooth tissue and

It consists of three distinct layers, which are rigid, thicker and highly muscular tissue. When the heart contraction occurs, arteries pump the blood into all parts of the body. Arteries are located deep into the body and red in colour. These blood vessels are with high blood pressure and move in a downward direction from the heart to the body tissues.

Arterioles are small diameter blood vessels that reach from an artery and lead towards capillaries. Capillaries are the smallest blood and form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The function of capillaries is the exchange of materials between the blood and tissue cells.

Note: Arteries carry oxygenated blood away from the heart to tissues except for pulmonary arteries, they carry blood to lungs for oxygenation.
