Friedreich's ataxiais a disorder where there’s a buildup ofironthat damages various organ systems - in particular, the nervous system gets damaged which causes ataxia, which is when the muscles don’t move in a coordinated way. The disorder also affects some internal organs like the heart a...
though, is that thepodocytes, which are the cells that have these long tentacle-like projections, called foot processes, that wrap around the capillaries in the glomeruli, are damaged. These damaged podocytes allow some plasma proteins and lipids to s...
Osmosis involves molecules present in solutions with very little solute content and are involved with making those solutes travel towards another solution that contains higher number of solutes. Molecules travel through a cell membrane that allows only a few substances to pass through it (rather than...
membrane. ♦ The pressure exerted by the molecules of the solvent on the membrane they pass through is calledosmotic pressure. Osmotic pressure is the energy driving osmosis and is important for living organisms because it allows water and nutrients dissolved in water to pass through cell ...
How do osmosis exhibited in the cell membrane? Cell membranes allow water to move into and out of the cell.When water moves across a cell membrane in a particular direction(see Figure 3), it is called osmosis. The direction water moves across the membrane depends on the concentration of par...
Also, other conditions likekidney hyperperfusionor increased perfusion of blood, as well asincreased pressure in the glomerular capillarieshave been linked to FSGS as well. 与原发性FSGS不同,继发性FSGS有其明确的病因, 有几个病理过程可能与之有关。
Let's review. We've learned that osmosis is the flow of water down its concentration gradient across semi-permeable membranes, like our cells' plasma membranes. In hypotonic solutions, where the concentration of solutes is lower outside than inside the cell, water flows into cells and makes th...
Since water molecules arepolarmolecules, they need channel proteins to move down theirconcentration gradient. These channel proteins are embedded in the cell membrane and provide a hydrophilic passageway through which water can move across. What drives the water molecules to move is theosmotic (pressur...
diffusion.Osmosismoves from an area of low concentration to high concentration. Inosmosiswater moves in the opposite way. Water flow is determined by the concentration‚ not the nature of the solute. There are a couple of things to consider for diffusion to work. The size of the cell‚ ...
To solve the question regarding osmosis and its characteristics, we will analyze each statement provided in the question step by step.Step 1: Understand Osmosis Osmosis is defined as the movement of water across a semipermeable
