Firlakuza [10]

Answer:

The oxygenated blood enters into the heart by pulmonary veins into the left auricle, then the left ventricle. Then this RBC enters the aortic valve and moves upward.

It enters the aorta and from the aorta to aortic vessels. From aortic vessels, the blood goes to descending aorta. This supplies RBC to different tissue parts.

From descending aorta the blood flows to iliac arteries which are further branched into several arteries, which supply blood to lower part of the body i.e. legs, pelvis.

The subclavian artery provides blood to hands and shoulders, hands. Left and right carotid arteries supply blood to the brain from the heart.
