Pronunciation: [ˈɛkstɹəvˌase͡ɪt] (IPA) 
The word "extravasate" is spelled with an "x" and a "v," which can be tricky for some. The IPA phonetic transcription of this word is /ɛkstrəˈvəseɪt/. The "x" is pronounced as a combination of /ks/ and the "v" as /v/. The stress is on the second syllable, which has the "e" and "a" forming the /seɪt/ sound. This word means "to force out of a vessel and into surrounding tissue," and is commonly used in the medical field.
Extravasate is a verb that refers to the process of a fluid, usually blood or lymph, escaping from its normal vessels or channels and accumulating in surrounding tissues. This leakage can be caused by damage or rupture of blood vessels, leading to the fluid spilling out into areas where it shouldn't be.
The term is commonly used in medical and biological contexts to describe the escape of fluids from their intended pathways, resulting in swelling, bruising, or other abnormal accumulations. For instance, when blood escapes from a damaged blood vessel, it may extravasate into the surrounding tissues, causing a hematoma or localized area of bleeding. Similarly, in the case of lymphatic vessels, if lymph leaks from its channels, it can extravasate and create lymphedema or a buildup of lymph fluid.
Extravasation can be a result of various factors, including trauma, infection, vascular diseases, or medical procedures. It often requires prompt medical attention to address the underlying cause and prevent further complications.
In summary, extravasate is a term used to describe the escape or leakage of fluids, particularly blood or lymph, from their normal vessels or channels into surrounding tissues. It is commonly seen in instances of vessel damage, leading to swelling or localized bleeding, and requires appropriate medical management.

The word "extravasate" has Latin origins. It is derived from the Latin word "extravasatus", which means "forced out of the usual course" or "spilled out". The Latin term is a composite of two elements: "extra" meaning "beyond" or "out of" and "vas", which translates to "vessel" or "container". In medical terminology, "extravasate" refers to the process of a fluid, such as blood, seeping or escaping from its usual vessels or channels to accumulates in surrounding tissues.
