filters the blood to prevent blood cells and proteins from entering into the filtrate and to allow the passage of blood plasma.
The two stages of filtration in the nephrons are glomerular filtration and tubular reabsorption. Glomerular filtration occurs in the glomerulus where blood is filtered to form a filtrate. Tubular reabsorption involves the reabsorption of essential substances such as water, glucose, and ions back into the bloodstream from the filtrate in the renal tubules.
Large proteins are typically found in plasma due to their size and charge, which prevents them from passing through the glomerular filtration barrier into the tubular fluid. The glomerular filtration barrier only allows small molecules and ions to pass through, while larger proteins are retained in the bloodstream.
Glomerular hydrostatic pressure is the pressure exerted by the blood within the glomerular capillaries of the kidney. It is a driving force for the filtration of blood to form urine. An appropriate balance of glomerular hydrostatic pressure is important for proper kidney function.
No, the body does not adjust its pH through glomerular filtration. The kidneys play a role in maintaining pH balance through multiple processes such as reabsorption and secretion of ions, and the excretion of acid or base in the urine.
Total glomerular filtration would decrease due to the blockage of the collecting ducts, leading to reduced urine production. This blockage would prevent the reabsorption of water and solutes from the tubular fluid, resulting in a higher concentration of solutes in the urine that is formed.

Tubular reabsorption is the movement of filtrate from renal tubules back into blood in response to the body's specific needs.
The mechanism of urine formation takes place by three steps. they are glomerular filtration, tubular reabsorption and tubular secretion.
No, glomerular filtration is not an ATP-driven process. It occurs passively based on the pressure gradient across the glomerular capillaries and the filtration barrier. ATP is mainly required for active processes in the kidney such as tubular reabsorption and secretion.
The two stages of filtration in the nephrons are glomerular filtration and tubular reabsorption. Glomerular filtration occurs in the glomerulus where blood is filtered to form a filtrate. Tubular reabsorption involves the reabsorption of essential substances such as water, glucose, and ions back into the bloodstream from the filtrate in the renal tubules.
Tubular secretion is a part of urine formation occurring within the nephrons of the kidneys. After glomerular filtration, in which fluids from the blood pass into the glomerular capsule of the renal tubule, the filtrate is subject to tubular reabsorption and tubular secretion within the convoluted tubules and collecting ducts of the nephrons.

These are 1. Glomerular filtration, 2. Selective re-absorption and 3. Tubular secretion. All these three steps are performed in kidney nephrons.
