Summary Introduction
To analyze:
Tubular reabsorption and secreation of nephrons.
Introduction:
Nephrons are the structural and functional unit of urinary system. The process that decides which blood solutes are retained in the body and which ones are eliminated in the urin are called tubular reabsorption and tubular secretion. The proximal convoluted tubule carries out both tubular reabsorption and tubular secretion.In cortical nephrons, peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole. They travel adjacent to nephrons and helps in reabsorption and secretion between blood and the proximal convoluted tubule.

Students have asked these similar questions
the fine network of blood vessels which surrounds all of the tubules of the nephron is called the __________.
The cells lining the nephron component marked by the black asterisk
1. bind the 'parathyroid hormone' to increase the reabsorption of calcium ions from the filtrate into peritubular capillary blood
2. Function to regulate pH of the blood by secreting bicarbonate ions and reabsorbing hydrogen ions
3. bind the hormone 'aldosterone' to increase sodium reabsorption from the filtrate (with passive reabsorption of water)
Choose from the following:
(A) 1
(B) 2
(C) 3
(D) 1 and 2
(E) 2 and 3
(F) 1, 2, and 3
To say that your body has somatic control over your external urethral sphincter that means you can ________ control that sphincter.
