Answer
1. **Unwanted or Inappropriate Clotting in a Vessel:**
- **Thrombosis:** Thrombosis refers to the formation of a blood clot (thrombus) within a blood vessel. It can occur within arteries or veins and may lead to partial or complete blockage of blood flow.
2. **The Clot Itself:**
- **Thrombus:** A thrombus is a stationary blood clot that forms within a blood vessel. It can obstruct blood flow, leading to various complications depending on its location and size.
3. **A Clot That Breaks Free and Travels in the Bloodstream:**
- **Embolus:** An embolus is a detached, often dislodged fragment of a blood clot, fatty plaque, air bubble, or other material that travels through the bloodstream. When an embolus lodges in a smaller blood vessel and obstructs blood flow, it's referred to as an embolism.
- **Embolism:** An embolism occurs when an embolus, which is a dislodged fragment or material, becomes lodged in a blood vessel, obstructing blood flow. The term is often used in the context of a clot or other material causing blockage in a vessel distant from its site of origin.
These terms are essential in describing the various scenarios involving abnormal clotting and their potential consequences for the circulatory system.
