Capillary (noun) – Meaning, Examples & Etymology

noun

IPA:

/kəˈpɪl(ə)ri/

What does capillary mean?

A tiny blood vessel that connects the arterioles (small arteries) and venules (small veins) in the body's circulatory system.
"Capillary function is essential for oxygen delivery to tissues."

Detailed Meaning of Capillary

Capillaries are only one cell thick, which allows for the exchange of nutrients, gases, and waste products between the blood and the body's tissues. This exchange process is known as capillary exchange or microcirculation. Capillaries are found throughout the body, but are most densely located in organs such as the lungs, liver, and kidneys. They play a critical role in maintaining proper blood flow and oxygenation to these organs, as well as in regulating blood pressure and body temperature. Certain medical conditions can affect the function of capillaries, such as diabetes, which can cause damage to the capillaries in the eyes and kidneys. In short, capillaries are important structures that enable the exchange of materials between the blood and the body's tissues, and are essential for maintaining proper organ function.

Example Sentences for Capillary

6. The capillary can be affected by diseases like diabetes.

Origin and Etymology of Capillary

The noun 'capillary' finds its etymological roots in Latin. It is derived from the Latin word 'capillaris,' which means 'pertaining to hair' or 'hairlike.' This term was chosen because capillaries, the tiny blood vessels that form an intricate network throughout the body, are so narrow and thin that they resemble fine hairs. Capillaries play a crucial role in the circulatory system, facilitating the exchange of oxygen, nutrients, and waste products between blood and body tissues. The etymology of 'capillary' underscores the visual similarity between these slender vessels and hair, highlighting their delicate and intricate
