Small molecules such as water, ions, glucose, amino acids, and nitrogenous wastes like urea and creatinine leave the glomerulus and enter the glomerular capsule through a process called filtration. Large proteins and cells are typically too large to pass through and are retained in the bloodstream.

What all leaves the glomerulus and goes to the glomerular capsule?

Water, ions, nutrients, and waste products like urea and creatinine leave the glomerulus and enter the glomerular capsule through the process of ultrafiltration in the initial stages of urine formation in the kidney.


Why is there no protein in the glomerular filtrate or unine?

Protein is typically absent in glomerular filtrate and urine due to the selective permeability of the glomerular filtration barrier, which consists of endothelial cells, a basement membrane, and podocytes. These structures prevent large molecules like proteins from passing through while allowing smaller molecules and water to filter through. Additionally, any small amounts of protein that may enter the filtrate are usually reabsorbed by renal tubules before urine formation. Therefore, healthy kidneys maintain minimal to no protein levels in urine.


Which body part filters blood and wastes from entering the kidney?

The body part that filters blood and wastes before they enter the kidney is the nephron. Each kidney contains approximately one million nephrons, which consist of a glomerulus that filters blood and a tubule that processes the filtrate to reabsorb necessary substances and excrete waste. The glomerulus acts as the initial filtration unit, allowing water, ions, and small molecules to pass while retaining larger molecules like proteins and blood cells.


Does blood enter the nephron first or second?

Blood enters the nephron first. It enters through the afferent arteriole into the glomerulus, where filtration takes place to form the initial filtrate.


What type of molecules cannot enter the cell?

polar molecules are repelled by the cells electrical charge.

What are the layers in the renal corpuscle through which filtrate must pass to enter the capsular space?

The renal corpuscle filtration barrier is composed of: the fenestrated endothelium of glomerular capillaries, the fused basal lamina of endothelial cells and podocytes, and the filtration slits of the podocytes.


Where does blood plasma enter the nephron and what ultimately does this plasma turn into?

Blood plasma enters the nephron through the glomerulus in the Bowman's capsule. This plasma is filtered through the nephron's tubules, where water and small molecules are selectively reabsorbed, while waste products and excess substances are excreted as urine.

Why was john glenn's capsule on fire during entry?

When the capsule begins to enter the atmosphere, the friction of the air on the bottom, or heat sheild, of the capsule creates so much heat that it looks like it is on fire.


When a space capsule returns to earth after a mission it glows red hot as it enter atmosphere because of?
