|
filtrate is transported into interstitual fluid
|
|
|
filtrates are reabsorbed into the blood
|
|
|
water and solutes are driven across the wall of glomular capillaries
|
|
|
H+, K+, and urea are transported into the filtrate
|
Detailed explanation-1: -Filtrate is produced by the glomerulus when the hydrostatic pressure produced by the heart pushes water and solutes through the filtration membrane. Glomerular filtration is a passive process as cellular energy is not used at the filtration membrane to produce filtrate.
Detailed explanation-2: -The glomerulus filters your blood As blood flows into each nephron, it enters a cluster of tiny blood vessels-the glomerulus. The thin walls of the glomerulus allow smaller molecules, wastes, and fluid-mostly water-to pass into the tubule. Larger molecules, such as proteins and blood cells, stay in the blood vessel.
Detailed explanation-3: -Which process occurs across the walls of the glomerular capillaries? filtration.
Detailed explanation-4: -The process by which glomerular filtration occurs is called renal ultrafiltration. The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron.
Detailed explanation-5: -The glomerular capillaries are the barrier to distribution of large plasma proteins into urine. Large proteins such as albumin and IgM are impeded by the capillaries whereas smaller proteins pass through the filtration barrier into the tubular fluid.
