The kidney works by filtering out the small molecules and initially retaining the larger red blood cells then actively transporting ions like sodium, calcium and potassium, and retrieving proteins and sugars back into the blood stream. This is advantageous because the blood levels set the amount of each of the smaller compounds that are returned until the blood reaches the right concentration for each molecule.

Where is the site of the filtrate formation?
Glomerulus is the filter that makes the filtrate.
What is the role of glomerulus in excretion?
It is the capillary tuft in the kidney that is involved in the first step of filtering the blood to form urine.
Filtration occurs at the -------- part of the nephron?
In the Glomerules
The renal corpuscle includes which parts of the nephron?
Bowman's capsule and glomerulus (capillary tuft).
What process occurs in the Bowman's capsule?
Bowmans capsule is part of the functioanl unit of the kidney called the nephron. The kidney job in the body is to filter blood and remove wastes via the urine. At the very start of each nephron is a very smalle blood network called the glomerulus. The diameter pf the vessel leaving the glomerulus (the efferent vessel) is smaller than that coming to the glomerulus (the afferent vessel) and so a large pressure occurs. This helps push the wastes as well as some nutrients and a lot of water out of the glomerulus. To stop if all just floating of into the body a a structue surround the glomerulus and takes up all the thing the glomerulus lets out. This is the glomerulus and it passes what it gets on through the vessels of the nephron where much is reabsorbed and the rest is excreted as urine.
What are filter sacs in the kidneys called?
Glomerulus
What structures filter blood in the kidneys?
The structures are the glomerulus and tubules.
What structures filter blood in a kidney?
Renal corpuscle
Where is the site of the filtrate formation?
Glomerulus is the filter that makes the filtrate.
What is a specialized capillary bed designed to function as a mechanical filter Answer?
Glomerulus in the bow man's capsule
What is the C-shaped structure surrounding the glomerulus that acts as a filter in the formation of urine?
Bowmans capsule
What is the structure of glomerulus?
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.
Is the glomerulus thought of as the filter of the kidney since it forms a fluid called filtrate or ultrafiltrate from the blood?
true
What is surrounded by the Bowman's Capsule?
the glomerulus
What is the role of glomerulus in excretion?
It is the capillary tuft in the kidney that is involved in the first step of filtering the blood to form urine.
What are the tiny structures in the kidneys where the blood is actually filtered and urine is formed?
Glomerulus are tufts of capillaries in the kidney nephrons that filter blood.
Filtration occurs at the -------- part of the nephron?
In the Glomerules
