Deoxygenated blood that has been returned to the body enters the circuit in the right atrium of the heart, where the right ventricle pumps it to the lungs. Blood is oxygenated in the lungs and then returned to the left atrium to complete the circuit.
<h3>What is the primary purpose of pulmonary circulation?</h3>
The right ventricle's oxygen-poor blood is transported to the lungs through pulmonary circulation, where it receives a fresh blood supply. The oxygenated blood is then returned to the left atrium.
<h3>Where does the pulmonary blood flow start and stop?</h3>
The pulmonary circulation facilitates the exchange of gases between the pulmonary capillaries and alveoli. All of the cardiac output travels through this circuit, which stretches from the heart to the lungs and back to the heart.
<h3>What components make up the pulmonary circulation?</h3>
The right and left main pulmonary arteries and their lobar branches, intrapulmonary arteries, large elastic arteries, small muscular arteries, arterioles, capillaries, venules, and large pulmonary veins are all part of the pulmonary circulation. The pulmonary trunk, also known as the "right ventricular outflow tract," is another name for this system.
