What is a clot or piece of tissue circulating in the blood?

A thrombus is a blood clot in the circulatory system. It attaches to the site at which it formed and remains there, hindering blood flow. Doctors describe the development of a thrombus as thrombosis.

What fibrillation does the heart muscle quivers ineffectively?

Ventricular fibrillation is a type of abnormal heart rhythm (arrhythmia). During ventricular fibrillation, disorganized heart signals cause the lower heart chambers (ventricles) to twitch (quiver) uselessly. As a result, the heart doesn’t pump blood to the rest of the body.

Is the resection and removal of the lining of an artery?

Carotid endarterectomy is an operation during which your vascular surgeon removes the inner lining of your carotid artery if it has become thickened or damaged. This procedure eliminates a substance called plaque from your artery and can restore blood flow. As you age, plaque can build up in the walls of your arteries.

What is the abnormal protrusion of a heart valve that results in the inability of the valve to close?

Mitral valve prolapse (MVP) is the bulging (prolapse) of 1 or both of the mitral valve flaps (leaflets) into the left atrium when the heart contracts. When the flaps don’t close properly, blood leaks backward. This is called regurgitation.

Is plasma fluid after the blood cells and clotting proteins have been removed?

Plasma is the liquid component of blood after all of the cells and platelets are removed; serum is plasma after coagulation factors have been removed.

What’s another name for blood clot?

A blood clot that forms inside one of your veins or arteries is called a thrombus. A thrombus may also form in your heart. A thrombus that breaks loose and travels from one location in the body to another is called an embolus.

Is the surgical removal of the lining of a portion of a clogged carotid artery leading to the brain?

Carotid endarterectomy (CEA) is surgery to treat carotid artery disease. The carotid arteries are the main blood vessels that carry oxygen and blood to the brain. In carotid artery disease, these arteries become narrowed. This reduces blood flow to the brain and could cause a stroke.

Which term describes a fatty deposit on an artery wall?

Atherosclerosis, sometimes called “hardening of the arteries,” occurs when fat, cholesterol, and other substances build up in the walls of arteries. These deposits are called plaques. Over time, these plaques can narrow or completely block the arteries and cause problems throughout the body.

What reduces the workload of the heart by slowing the rate of the heartbeat?

Beta Blockers. Beta Blockers block the effect of adrenaline (the hormone norepinephrine) on the body’s beta receptors. This slows down the nerve impulses that travel through the heart. As a result, the resting heart rate is lower, the heart does not have to work as hard and the heart requires less blood and oxygen.

What is the surgical removal of a portion of a blood vessel called?

During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow.

Which term means surgical removal of plaque?

atherectomy. The surgical removal of plaque buildup from the interior of an artery.

Which term means the surgical removal of the lining of the portion of a clogged artery?

11/04/2014. Carotid endarterectomy is a surgical procedure to restore blood flow through a narrowed or blocked carotid artery. The carotid arteries are the blood vessels in the neck that carry blood to the brain.

What is the other name of mitral valve?

The mitral valve is also known as the bicuspid valve. This is one of the heart’s four valves that help prevent blood from flowing backward as it moves through the heart.

What is the mitral valve also known as?

The mitral valve also called bicuspid valve, is located between the left atrium and left ventricle and is composed of the mitral annulus, papillary muscles, anterior leaflet, and posterior leaflet and chordae tendinae, all these components form the valve apparatus which prevents the blood backflow from the left

What does pulmonic regurgitation mean?

Pulmonary regurgitation is a condition where the pulmonary valve, which regulates blood flow from the right side of the heart to the lungs, doesn’t close properly and a portion of it leaks back to the right side of the heart.

What does a Thrombocyte do?

Platelets (thrombocytes) are colorless blood cells that help blood clot. Platelets stop bleeding by clumping and forming plugs in blood vessel injuries. Thrombocytopenia might occur as a result of a bone marrow disorder such as leukemia or an immune system problem.

What name is given to the fluid component of blood?

Plasma. The liquid component of blood is called plasma, a mixture of water, sugar, fat, protein, and salts.

What is the function of plasma?

The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body. Blood plasma also carries all parts of the blood through your circulatory system.
