The most selective pores in the filtration membrane are located in the?
lamina densa
Which structures form the filtration membrane in the nephron?
glomerulus and glomeral capsule
In m Endo Agar 'm' Stands for?
m-Endo agar is a microbial growth medium used for aqueous cultivation of coliforms by membrane filtration. The 'm' presumably refers to the process of membrane filtration.
Why are useful molecules like glucose and other nutrients found in the filtrate along with urea and other wastes?
because glucose and other nutrients are small to filtrate through the filtration membrane and glucose is essential to be in the filtration membrane.
What chief force pushing water and solutes out of the blood across the filtration membrane is?
True.
What are the three capillaries?
Continuous-Fenestrated-Sinusoids Capillaries D.
Starlings Law of Capillaries states that?
Starling's law of the capillaries states that the net filtration = forces favouring filtration vs. forces opposing filtration. These forces include: Tonicity, Blod Hydrostatic Pressure (BHP), Blood Colloid Osmotic Pressure (BCOP), Interstitial Fluid Hydrostatic Pressure (IFHP), Interstitial Fluid Colloidal Pressure (IFCOP) and membrane permeability. Therefore effective filtration pressure (and the application of Starling's Law of the Capillaries) is defined as such: EFP=(BHP + IFCOP) - (IFHP + BCOP) Therefore: BHP + IFCOP moves fluid out of the capillaries and IFHP + BCOP moves fluid into capillaries
What visceral membrane forms part of the filtration membrane?
glomerular capsule
The filtration membrane includes all except?
The filtration membrane includes the glomerular endothelium, podocytes, and basement membrane. The only thing it doesn't include is the renal fascia.
What membrane is the extremely thin barrier between the alveoli and the capillaries?
respiratory membrane
What is different about the capillary exchanges seen in a capillary with fenestrations and intercellular clefts and the exchanges seen in a capillary lacking those modifications?
Capillaries with fenestrations and intercellular clefts allow for different diffusion of substances depending on structural characteristics (and permeability) of the capillary. Fenestrated capillaries are found where absorption are a priority, such as the intestines or endocrine glands, or where filtration occurs, such as the kidneys. A fenestra is an oval pore covered (usually) by a delicate membrane, and is much more permeable than a plain plasma membrane. Intercellular clefts are gaps in the plasma membrane, or areas not joined tightly, and are another way substances can enter the cell. Almost all capillaries have these. Substances can diffuse directly through the plasma membranes of cells only if the substances are lipid-soluble (like the respiratory gases), and certain lipid-insoluble substances can enter or leave the blood by passing through the plasma membranes of endothelial cells within vesicles, by endo or exocytosis.
Do filtration requires a membrane-bound carrier for transport?
no
In terms of filtration define selectivity?
In terms of filtration, selectivity is a parameter. It is 1 of 2 factors that determines how successful the membrane filtration process was.
Its Inner visceral membrane forms part of the filtration membrane?
visceral layer of glumerular capsule
The capillaries in the hepatic sinusoids are somewhat unique in that there is an excessively thick basement membrane associated with these capillaries?
False
What is the movement of water and solutes through a membrane because of hydrostatic pressure called?
osmosis
Where materials move out of a cell by the fusion of vesicles with membrane?
filtration
