Description: The proximal tubule is the initial portion of the renal tubule in the
nephron, the functional unit of the kidney. It reabsorbs water, salts,
glucose, and amino acids from the fluid filtered out of the blood by the
renal corpuscle.
Description: The loop of Henle is a part of the renal tubule that passes through the
medulla of the kidney. The tubule turns to pass back into the cortex. This
portion of the tubule concentrates salts from the urine in the
interstitium, the tissue space around the loop.
Description: The distal convoluted tubule is the distal portion of the renal tubule in
the nephron of the kidney. It has cells specialized in active transport and
is involved in maintaining pH of the urine and blood. The distal tubule is
heavily regulated by the endocrine system.
