GENERAL HISTOLOGY

Detailed explanation-1: -The glomerulus filters water and small solutes out of the bloodstream. The resulting filtrate contains waste, but also other substances the body needs: essential ions, glucose, amino acids, and smaller proteins. When the filtrate exits the glomerulus, it flows into a duct in the nephron called the renal tubule.

Detailed explanation-2: -Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.

Detailed explanation-3: -Tubular secretion: ("selectively adding to the waste container") is the process of selectively moving substances from the blood into the filtrate. Like tubular reabsorption, it occurs along the length of the tubule and collecting duct.

Detailed explanation-4: -Key Points. The glomerulus is the site in the nephron where fluid and solutes are filtered out of the blood to form a glomerular filtrate.
