What is the term for the escape of blood from the vascular system?

The term that describes the escape of blood from the vascular system is "hemorrhage." This occurs when blood vessels are damaged, leading to blood leaking into surrounding tissues or outside the body. Hemorrhages can be categorized as either external, where blood flows out of the body, or internal, where it collects within the body cavities or tissues.

Understanding hemorrhage is crucial in funeral service education as it often has implications for the embalming process and the aesthetic presentation of the deceased. Managing visible signs of blood loss and understanding the nature of such injuries aids in providing a respectful and dignified preparation of the body.

Thrombosis refers to the formation of a blood clot within a blood vessel, which is quite different as it does not imply the escape of blood but rather a blockage in the flow. Ischemia involves a reduction in blood supply to tissues, leading to potential tissue damage, while hyperemia refers to an increase in blood flow to an area, often associated with inflammation or injury. Each of these terms relates to blood flow but captures different physiological processes unrelated to the initial escape of blood from vessels.
