A blood clot is formed when blood platelets, proteins, and cells stick together. A thrombus is a blood clot that attaches to the walls of a blood vessel. It is called an embolus if it moves through the bloodstream and blocks the flow of blood in another area of the body.
#13 ven/o, ven/i, phleb/o
ven/o, ven/i or phleb/o is a combining form that pertains to "vein".
A vein is a blood vessel that carries deoxygenated blood from the tissues back to the heart. The pulmonary vein and umbilical vein, which carry oxygenated blood to the heart, are exceptions. Compared to arteries, veins are less muscular and are often located closer to the skin.
#14 valv/o, valvul/o
valv/o or valvul/o is a combining form that pertains to "valve".
A heart valve is a flap that prevents blood from flowing backwards. The four heart valves that ensure blood flows in the right direction are the mitral, tricuspid, pulmonary, and aortic valves. During each heartbeat, the flaps (leaflets) of the valve open and close.
#15 ventricul/o
ventricul/o is a combining form that pertains to "ventricle".
A ventricle can pertain to a chamber of the heart or a section of the brain. The heart ventricle is one of two large chambers near the bottom of the heart where blood collects and travels to the lungs and other parts of the body.
