Final answer:
a) Thrombus A blood clot that forms within the vascular system is known as a thrombus. It is an aggregation of blood components, which can adhere to the vessel wall or occlude the vessel, potentially leading to complications such as deep vein thrombosis.
Step-by-step explanation:
A blood clot that forms within the vascular system is a thrombus. A thrombus is a collection of blood components, including platelets, erythrocytes, and white blood cells, which may become entangled in a network of fibrin strands. This can occur within an intact or slightly damaged blood vessel. A thrombus may adhere to the vessel wall and reduce blood flow, or in more severe cases, block it entirely, leading to conditions like deep vein thrombosis (DVT) or other complications.
When part of a thrombus detaches and moves within the bloodstream, it becomes an embolus, which is different from a thrombus. A thrombus can lead to increased blood pressure in the affected region and requires the heart to work harder to maintain blood flow.A blood clot that forms within the vascular system is a thrombus. A thrombus is an aggregation of platelets, erythrocytes, and even WBCs trapped within a mass of fibrin strands. It can form within an intact or slightly damaged blood vessel and can impede blood flow. When a portion of a thrombus breaks free from the vessel wall and enters the circulation, it is referred to as an embolus.
