What are the parts of pulmonary circulation?
The pulmonary circulation includes the pulmonary trunk (also called the “right ventricular outflow tract”), 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.
What general body parts does the pulmonary circulatory system serve?
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.
What are the 4 main parts of the circulatory system?
The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
What are the 5 major parts of the circulatory system?

What is the largest artery in the body?
Aorta Anatomy The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What is a blocked artery called?
Atherosclerosis, otherwise known as hardening of the arteries, clogged arteries, or blocked arteries, is a buildup of plaque in the blood vessels. Plaque is a waxy, sticky substance made up of cholesterol, fat, calcium, and other matter that is found in the blood.
What is the correct flow of blood?
Blood flows through your heart and lungs in four steps: The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
What is the correct route for blood flow in a human?
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
What is the correct route for blood flow in a woman?
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
What is the main organ of the circulatory system?
The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.
What is oxygenated blood called?
Oxygenated blood is also called arterial blood. After the respiration in the lung, the blood has plenty of oxygen, and its color is bright red. Oxygenated blood flows in the pulmonary vein and in the arteries.
Is oxygenated blood good?
A healthy, normal blood oxygen level remains around 95 percent to 100 percent. You can monitor your blood oxygen level at home with a pulse oximeter. Values below 90 percent are considered low.
Which blood is oxygenated and deoxygenated?
Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.
What does oxygenated blood look like?
Blood that has been oxygenated (mostly flowing through the arteries) is bright red and blood that has lost its oxygen (mostly flowing through the veins) is dark red. Anyone who has donated blood or had their blood drawn by a nurse can attest that deoxygenated blood is dark red and not blue.
