Big and Small Circulatory Order – Circulation of blood is an important process in meeting the body’s oxygen needs. Through blood circulation, the body gets the substances it needs, and can get rid of the substances the body needs, so as not to threaten the health of the body. Circulation also helps in regulating body temperature, and distributing hormones to the organs that need them.
Blood circulation can run well, can not be separated from the help of the heart. The heart beats to pump blood to all parts of the body. The normal adult heart rate is around 72 beats per minute. This pulse weakens with age and when a person is asleep. The blood circulation consists of blood vessels, a number of muscles that help the blood flow, the heart and the blood itself. Blood flows away from the heart to all parts of the body. Read: Circulatory function
Blood flows from the left side of the heart to the arteries, the arteries will drain oxygenated blood to the arteries from the arteries, the blood will pass through the arterioles, which are the smallest arteries. Blood that carries oxygen will release oxygen throughout the body to help the body’s metabolic processes. Circulation of blood in humans rotates twice through the heart, this is because human blood circulation is a double circulation, consisting of large and small blood circulations. The following is an explanation of the order of the small and large blood circulation:
1. Order of major blood circulation
The major blood vessels are complex blood vessels. This circulation starts from the left ventricle which drains blood to the oarta, the oarta receives blood containing oxygen and drains it in the arteries which will drain it throughout the body, until the blood enters the veins and transports blood containing carbon dioxide. Blood containing carbon dioxide is flowed into the veins, which will pass through the remur vein, renal vein, and hepatic portal vein which penetrates to the liver. From the liver the blood will flow to the hepatic vein, this vein is a vein that carries carbon dioxide blood from the lower part of the human body, for the upper part, the blood will be carried by the subclavical vein and the jaglum vein. the two veins. The lower and upper veins will meet in one vein, the vena cava and begin to enter the right side of the heart, namely the right atrium and right ventricle.
2. Order of small blood circulation
Minor circulation is the circulation of blood that routes from the lungs to the heart. So blood containing carbon dioxide will be released by the right heart, namely the right ventricle in the pulmonary artery, blood containing carbon dioxide will flow in these vessels until it reaches the lungs, then the lungs will release carbon dioxide and breathe in air containing oxygen. Oxygen will be inhaled by the lungs to the brim, after that the oxygen-containing blood will be bound by blood and brought back to the heart through the pulmonary veins entering the left atrium to the left ventricle. Minor circulation is blood circulation in a short route. But this process is an important process for the body. Read: The circulatory system of large and small in humans
