What is the function of bowman's capsule , glomerulus, pct ,DCT and other part of nephron

Solution

1)

The Bowman's capsule is an expansion at the closed end of a renal tubule. A kidney's renal corpuscle is composed of tangled clusters of blood capillaries, called a glomerulus, and a thin-walled, saclike structure called the Bowman's capsule, which surrounds the glomerulus. The Bowman's capsule is composed of two layers of cells: an inner layer that closely covers the glomerulus, and an outer layer that is continuous with the inner layer and with the wall of the renal tubule.

The function of the kidney involves removing waste and harmful products from the blood, while conserving useful substances and water. In order to achieve this, different parts of the kidney act together to filter out and then reabsorb different factors from the blood.

Bowman's capsule and the glomerulus form a unit called the renal corpuscle, in which the initial process of filtration occurs

2)

A glomerulus is a network of capillaries located at the beginning of a nephron in the kidney. It serves as the first stage in the filtering process of the blood carried out by the nephron in its formation of urine.

The filtrate then enters the renal tubule, of the nephron. The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation. ... The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall renal function, is the glomerular filtration rate (GFR).

3)reabsorbs: all of the organic nutrients, plasma protein, 60% of the sodium and chloride ions and water, and calcium/potassium/magnesium/bicarbonate/phosphate/sulfate ions

4)active secretion of ions and acids, selective reabsorption of sodium and calcium ions, very little reabsorption of water

5)
A nephron is responsible for removing waste products, stray ions, and excess water from the blood. The blood travels through the glomerulus, which is surrounded by the glomerular capsule. As the heart pumps the blood, the pressure created pushes small molecules through the capillaries and into the glomerular capsule. This is the, more physical function of the nephron. Next, the ultrafiltrate must travel through a winding series of tubules. The cells in each part of the tube have different molecules that they like to absorb. Molecules to be excreted remain in the tubule, while water, glucose and other beneficial molecules work their way back into the bloodstream. As the ultrafiltrate travels down the tubules, the cells become more and more hypertonic compared to the ultrafiltrate. This causes a maximum amount of water to be extracted from the ultrafiltrate before it exits the nephron. The blood surrounding the nephron returns to the body via the interlobular vein, free of toxins and excess substances. The ultrafiltrate is now urine, and moves via the collecting duct to the bladder, where it will be stored.
