They are involved in the flow of water and urea from the inside of the collecting duct cell into the extracellular renal medullary space. Mice made genetically deficient in aquaporin-4 demonstrate a mild urinary concentrating defect,111 whereas those with deficiency of aquaporin-3 alone, or ...
In contrast, adults with hydronephrosis usually develop it as a result of an acquired disease, likekidney stones, which is the most common cause, as well as prostatic hyperplasia, or enlarged prostate, which blocks the flow of urine out of the bladder. 对比之下,成年人发生肾积水更多见于后天性...
aThis movement is called osmosis: osmotic pressure is the force that causes water to flow across a membrane to the side with a higher concentration of ions. 这运动称渗透作用: 渗透压是造成水横跨膜流动对边以离子的更高的浓度的力量。[translate]...
The meaning of OSMOSIS is movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane. Ho
Ultimately, this is how nutrients, like O2 get pushed out to the organs and tissues that need it; and how wastes, like CO2 (main by-product of cellular respiration) gets removed. 循环系统,也称作心血管系统,由2个关键部分构成:心脏(泵血)、血管(把血液输送到身体各处,再将其送回心脏)。在此...
英语翻译 Water gets into a fish's body through osmosis.For example,if there is more water outside of a cell than inside,water will try to flow into the cell until there is the same concentration of water on either side of the cell's membrane.The body of a fish acts the same way,...
model. diffusion is the flow of a chemical from where it's more concentrated to where it's less concentrated. think of a drop of dye spreading throughout a glass of water, or the smell of garlic wafting out of a kitchen. it keeps moving toward equilibrium until its concentration is the...
Two effects give rise to osmosis in a permeable membrane: the coupling effect between the ion streams and water, demonstrated by binary isotonic osmosis, and the osmotic difference between the outside solutions. But, in contrast to a semipermeable membrane, it is not the difference in the outsi...
Osmosis is defined as the movement of solvent molecules, such as water, across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration, in order to equalize the solute concentrations on both sides of the membrane. ...
A self-contained, transportable reverse osmosis water purification unit has a limited throughput of no more than about 20 gpm of permeate in a single pass operation with reverse osmosis ( RO ) modules which can be cleaned in place. When raw water is particularly fouled, the unit is operated ...
