The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
Video explanation. Author: Tanner Marshall, MS Editor: Rishi Desai, MD, MPH, Tanner Marshall, MS So when we talk about ischemia, we’re usually talking about this lack of blood flow to a specific area of tissue, so maybe like with a heart attack, a coronary artery in the heart gets blocked that supplies the left ventricle with blood...so that localized area of heart tissue doesn’t get ...
Under hypertonic conditions - conditions of high concentrations of either salts, substrates or any solute in the supernatant - water is drawn out of the cells through osmosis. This also inhibits the transport of substrates and cofactors into the cell thus “shocking” the cell.
Video explanation. Author: Tanner Marshall, MS Editor: Rishi Desai, MD, MPH, Tanner Marshall, MS Wolff-parkinson-white pattern, or WPW, is a type of heart arrhythmia caused by an accessory pathway, or an “extra” electrical conduction pathway connecting the atria and ventricles, or upper and lower chambers of the heart.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Video explanation. Author: Tanner Marshall, MS Editor: Rishi Desai, MD, MPH, Tanner Marshall, MS With peripheral vascular disease, vascular refers to the blood vessels, and peripheral means the outer limits or edge of something, which in this case refers to essentially any vessels that aren’t supplying the heart or the brain, like the legs, arms, or other organs.
Video explanation. Author: Thomas R. Shannon, DVM, PhD Editor: Rishi Desai, MD, MPH, Tanner Marshall, MS Heart failure’s used to describe a point at which the heart can’t supply enough blood to meet the body’s demands.
