The blood from the heart is transported to all parts of the body by the

Answer 1

The heart is the circulatory organ which helps to pump the blood to the various parts of the body. In humans, it is four chambered. It consists of auricles and ventricles. The auricles carry the oxygenated blood and the veins carry the deoxygenated blood.

Complete answer:
Arteries are the solid walled tubes by which the oxygenated blood is transported from the heart to all parts of the body. Arteries start with the aorta and this aorta is the biggest blood capillaries in the body. The aorta starts at the head of the left ventricle. Arteries divert oxygen-rich blood from the heart to the entirety of the body's tissues in all the parts of the body. They branch into many small and small blood capillaries when they move from the heart to all the organs in the body. Arteries have a pulse higher than other different parts of the circulatory framework.
The pressure in arteries changes during the cardiovascular cycle. It is most elevated when the heart contracts and least when the heart unwinds. The variation in pressure delivers a pulse, which can be felt in different regions of the body. Consequently, the blood from the heart is moved to all pieces of the body by the "arteries".

Note: All the arteries carry the oxygenated blood. But the pulmonary artery carries the deoxygenated blood from the heart and delivers it to the lungs for the purpose of oxygenation of the blood. And after adding oxygen to the blood, it was carried by the pulmonary veins to the heart.
