What system is responsible for blood cell formation?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
What is called blood?
Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets. Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs.
What is thrombus formation?
In short, thrombus formation is a dynamic process in which some platelets adhere to and others separate from the developing thrombus, and in which shear, flow, turbulence, and the number of platelets in the circulation greatly influence the architecture of the clot.

What is the name of the heartbeat that causes a clot to form?
Atrial fibrillation - An irregular and often rapid heartbeat that can lead to clot formation in a chamber of the heart. In atrial fibrillation , the heart's upper chambers called the atria beat irregularly and out of synch with the lower chambers. Atrial fibrillation can cause a stroke if the clot breaks free and travels to the brain.
What is a DVT?
Deep vein thrombosis (DVT) - A blood clot that forms in the veins located deep within a limb, usually the lower leg or thigh. By blocking the flow of blood back to the heart, these clots are often characterized by pain and swelling of the leg. Clots in the leg can break off, travel to the lungs and lodge there as pulmonary embolism (PE). These can be fatal because they block the flow of blood from the lungs back into the heart.
