The pressure of the blood forces water and other small molecules through a capillary wall into the start of a kidney tubule, forming filtrate.

blood pressure
glomerulus
Filtration occurs at the glomerulus, which is the initial part of the nephron where blood is filtered to form the filtrate that will eventually become urine.
glomerulus
Filtration in the nephron occurs in the glomerulus. Blood pressure forces small molecules like water, ions, and waste products to pass through the filtration membrane into the renal tubule. This initial filtrate is then processed through reabsorption and secretion in different parts of the nephron to form urine.
Filtration of blood occurs in the kidneys, specifically in the glomerulus within the nephron. The glomerulus filters waste and excess substances from the blood into the renal tubules for further processing and excretion as urine.
The cluster of capillaries in the kidney where filtration occurs is called the glomerulus. The glomerulus is part of the nephron, which is the functional unit of the kidney responsible for filtering blood to form urine.

The afferent arteriole directly feeds into the glomerulus, carrying blood into the renal corpuscle for filtration.
