General circulatory system anatomy

The high carbonic blood will gather into the arterioles and then into the larger veins, eventually, to the right atrium of the heart by the two upper and lower-aorta.

The circulatory system consists of the heart, which acts as a pump to push blood into the arteries and suck blood from the provinces. If the starting point of circulation is the left ventricle of the heart, blood is introduced into the aorta from which oxygen-rich blood is transported to the smaller arteries to reach the tissues of the organs. In organs, there is metabolism and air. The high carbonic blood will gather into the arterioles and then into the larger veins, eventually, to the right atrium of the heart by the two upper and lower- aorta. From the right atrium, blood descends to the right ventricle. It is the system cycle or the great cycle. Blood from the right ventricle containing carbon dioxide is pushed out into the pulmonary artery into the lungs. the lung gas exchange becomes oxygenated blood and leads to the left atrium, by the pulmonary veins, from the left atrium the blood flows to the left ventricle and the circulation continues. Blood from the heart to the lungs and back to the heart is called pulmonary circulation or small circulation.

There is also a portal system that receives blood from the gastrointestinal tract to the liver before it is poured into the lower aorta, which is discussed in the chapter of the digestive system.

Lymphatic circulation consists of lymph nodes and lymphatic vessels, which lead the lymphocytes as well as cell-produced protides, eventually flowing into the left- and right-hand veins.
