capillary vein
A capillary vein carries blood from the body's tissues back toward the heart.
Noun: A very small vein that directly connects to and continues from a blood capillary. It is part of the microcirculatory system where blood begins its return journey to the heart after exchanging gases and nutrients with tissues.
The term "capillary vein" is a precise anatomical term. It is used to describe the specific type of venule (small vein) that collects blood from capillaries. * In medical and biological contexts, it is often synonymous with "postcapillary venule" or simply "venule." * It is a technical term and is not typically used in everyday conversation.
