During filtration in the kidneys, components such as blood cells and large proteins remain in the blood, while smaller molecules like water, electrolytes, glucose, and waste products are filtered out into the urine. This selective filtration process helps maintain the proper balance of substances in the blood while removing excess waste. The retained components are crucial for various bodily functions and overall homeostasis.
What else can I help you with?
What products remain in the blood after filtration?
After filtration in the kidneys, waste products such as urea, creatinine, uric acid, and excess electrolytes (sodium, potassium) remain in the blood. The kidneys filter out these waste products and excess substances, which are then excreted in the urine.
Blood proteins and blood cells are too large to pass through the filtration membrane and should not be found in filtrate Question 12 answers?
Blood proteins and blood cells are indeed too large to pass through the filtration membrane in the kidneys. During the process of filtration in the kidneys, small molecules like water, electrolytes, and waste products are filtered into the urine, while larger molecules like blood proteins and cells remain in the blood. So, they should not normally be found in the filtrate that is eventually excreted as urine.
What are two substances that do not leave the glomerulus during filtration?
Substances like blood cells and large proteins do not normally leave the glomerulus during filtration in the kidneys. These large molecules are retained in the blood as they are too big to pass through the filtration barrier.
Does urea and glucose stay in the capillaries while blood cells and protein molecules move into the capsule of a nephron?
Yes, urea and glucose remain in the capillaries, while blood cells and protein molecules are filtered out and move into the capsule of a nephron during the process of renal filtration. This filtration is part of the first step in the formation of urine in the kidneys.
What would increase or decrease net filtration pressure?
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
What products remain in the blood after filtration?
After filtration in the kidneys, waste products such as urea, creatinine, uric acid, and excess electrolytes (sodium, potassium) remain in the blood. The kidneys filter out these waste products and excess substances, which are then excreted in the urine.

Is urine formed when absorption and reabsorption happen during blood filtration?
This is true.

Why increasing the size of the afferent arteriole increase volume of filtrate and rate filtration?
It increases the volume of blood at filtration site , increases the filtration gradient, and increases time of contact of blood with filtration site.
Are blood cells filtered out of the blood in the renal arterioles?
If the filtration slits of the filtration membrane are normal, then RBCs are not pushed out into the filtrate
What would increase or decrease net filtration pressure?
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
The process of the kidney taking out the impurities from the blood?
The kidney removes impurities from the blood in two ways. These processes are known as ultra filtration and selective reabsorption. The active component of the kidney involved with filtration is the nephron.
What is the arteriole that contains cleaner blood because it has been filtered by the glomerulus?
The efferent arteriole contains cleaner blood after filtration by the glomerulus because some waste products and excess substances have been removed during the process of blood filtration in the kidneys. This filtered blood then continues on to be circulated throughout the body.
Where filtration of blood takes place?
kidneys
What drives filtration at the glomerulus?
blood pressure
