A loop of blood vessels that circles between your heart and lungs. The heart pumps blood to the lungs to pick up oxygen, and the oxygen-rich blood is returned to the heart to be distributed to the body.
fluid buildup in the lungs that causes difficulty breathing, and sometimes coughing up blood, sweating, anxiety, and pale skin
a blood clot that formed in the veins and traveled through the bloodstream to block a lung artery; a potentially deadly complication of deep vein thrombosis
Scarring in the lungs.
Abnormally high blood pressure occurring in the arteries that supply blood to the lungs.
|Pulmonary regurgitation (insufficiency)||
Failure of the pulmonary valve to close properly, allowing blood to flow backwards into the right ventricle.
The narrowing or obstruction of the pulmonary artery or valve, which hinders the flow of blood to the lungs.
One of four heart valves, it maintains the one-way flow of blood from the heart to the lungs, opening when blood is ejected from the right ventricle and shutting as blood pressure falls.
The expansion and contraction of a blood vessel, especially an artery.
|pulse volume recording (PVR)||
a diagnostic test for peripheral artery disease that uses pressurized cuffs to measure blood flow in the leg arteries
Conduction fibers forming a network in the lower chambers of the heart that carry electrical impulses to the ventricle walls.
