That's what I want to know.
Capillary. The thin walls allow diffusion of materials to pass from the blood flow into the nephron.
Glomerulus
The glomerulus is the cluster of capillaries that branch off the renal artery in the kidneys. It is here that filtrationtakes place - small molecules such as glucose, water, ions and amino acids diffuse through the narrow capillary walls and into the nephron.
nephron
the substance might you expect to is dead blood cells
Blood is filtered through the glomerulus of the nephron in the kidney. The glomerulus acts as a specialized cluster of blood capillaries that allows small molecules such as water, salts, and waste products to pass into the nephron for urine formation.
The glomerulus is a cluster of capillaries that can be found in the kidney. Each cluster is next to a Bowman's capsule, which is the "filter unit" of the nephron. Blood passes from the renal artery into the glomerulus at high pressure, allowing small substances to diffuse into the nephron, via the Bowman's capsule.
exchage of materials between blood and tissues occur in cappilaries.
The capillary might burst (bruising) or, if it is the kidneys, the subject might pee blood.
There's the afferent arteriole which goes to the glomerulus and the efferent arterioles which comes out of the glomerulus. These arterioles then branch out surrounding the nephron, these are called peritubular capillaries and they allow for selective reabsorption of substances as well as secretion.
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 glomerulus of the nephron contains unfiltered blood, where blood is initially filtered to form the primary filtrate.
