What segment of the nephron loop participates in active transport of salts?
thick
In which segment of the nephron does tubular fluid have the highest osmolality?
Henles loop
What portion of the nephron does not absorb water passively by osmomis?
The Ascending potion of the henle's loop. Since it it is impermeable to water but permeable to electrolytes.
In which segment of the nephron would you find cuboidal cells with many microvilli and mitochondria?
The Proximal Convoluted Tubule
What controls urine volume?
Anti-diuretic hormone (ADH) is the hormone that regulates how much water is reabsorbed from the nephron into the bloodstream. It is called vasopressin in the US - ADH tends to be the British term, but they mean the same thing.
The U-shaped segment of the nephron is the?
The most distal portion of the nephron is the
What is the portion of the nephron that empties into the collecting duct?
The distal convoluted tubule is the portion of the nephron that empties into the collecting ducts. It is the last segment of the nephron.
What is the horse shaped segment of the nephron?
loop of Henle
In which segment of the nephron does tubular fluid have the highest osmolality?
Henles loop

Which part of a kidney dialysis apparatus actually takes the place of the nephron?
tubing made of selectively permeable membrane

What is the function of Vasopressin?
Arginine vasopressin (AVP), also known as vasopressin, argipressin or antidiuretic hormone (ADH), is a neurohypophysial hormone found in most mammals. Its two primary functions are to retain water in the body and to constrict blood vessels. Vasopressin regulates the body's retention of water by acting to increase water absorption in the collecting ducts of the kidney nephron. Vasopressin increases water permeability of the kidney's collecting duct and distal convoluted tubule by inducing translocation of aquaporin-CD water channels in the kidney nephron collecting duct plasma membrane. Vasopressin is a peptide hormone that controls the reabsorption of molecules in the tubules of the kidneys by affecting the tissue's permeability. It also increases peripheral vascular resistance, which in turn increases arterial blood pressure. It plays a key role in homeostasis, by the regulation of water, glucose, and salts in the blood. It is derived from a preprohormone precursor that is synthesized in the hypothalamus and stored in vesicles at the posterior pituitary. Most of it is stored in the posterior pituitary to be released into the bloodstream. However, some AVP may also be released directly into the brain, and accumulating evidence suggests it plays an important role in social behavior, bonding, and maternal responses to stress.
