Efferent arterioles
Efferent arterioles (pronunciation: /ɪˈfɛrənt ɑːrˈtɪəriːoʊlz/) are small blood vessels that carry blood away from the glomeruli of the kidneys.
Etymology
The term "Efferent arterioles" comes from the Latin word "efferens", which means "carrying away". This is in reference to the function of these arterioles, which carry blood away from the glomeruli.
Function
Efferent arterioles play a crucial role in the renal physiology. They carry blood away from the glomeruli, which are a network of tiny blood vessels in the kidneys where waste products are filtered from the blood. The efferent arterioles then lead to a network of peritubular capillaries and vasa recta, which further process the filtrate into urine.
Related Terms
- Afferent arterioles: These are the arterioles that carry blood to the glomeruli. They work in conjunction with efferent arterioles to maintain proper blood flow and filtration in the kidneys.
- Glomerular filtration rate: This is the rate at which blood is filtered in the glomeruli. The balance between afferent and efferent arterioles helps regulate this rate.
- Renal corpuscle: This is the part of the kidney that includes the glomerulus and the surrounding Bowman's capsule. The efferent arterioles carry blood away from the renal corpuscle.
