A red blood cell in a hypotonic solution, causing water to move into the cell. Blood cells in solutions with different osmotic pressure. Cytolysis would result in the image on the far right. Cytolysis, or osmotic lysis, occurs when the liquid outside a cell enters the cell causing it to burst. Water can enter the cell by diffusion through the ...
Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute. In biological systems, the solvent is typically water, but osmosis can occur in other liquids, supercritical liquids, and even gases. [11][12] When a cell is submerged in water, the water molecules pass through the cell membrane from an ...
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.
Nephrogenic diabetes insipidus, recently renamed arginine vasopressin resistance (AVP-R) and previously known as renal diabetes insipidus, is a form of diabetes insipidus primarily due to pathology of the kidney. This is in contrast to central or neurogenic diabetes insipidus, which is caused by insufficient levels of vasopressin (also called ...
Semipermeable membrane. Schematic of semipermeable membrane during hemodialysis, where blood is red, dialysing fluid is blue, and the membrane is yellow. Semipermeable membrane is a type of synthetic or biologic, polymeric membrane that allows certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure ...
The excretion occurs when substances such as glucose enter the kidney tubules and cannot be reabsorbed (due to a pathological state or the normal nature of the substance). The substances cause an increase in the osmotic pressure within the tubule, causing retention of water within the lumen, and thus reduces the reabsorption of water ...
Vasopressin. Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, [5] is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, [6] and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles ...
Osmoreceptor. An osmoreceptor is a sensory receptor primarily found in the hypothalamus of most homeothermic organisms that detects changes in osmotic pressure. Osmoreceptors can be found in several structures, including two of the circumventricular organs – the vascular organ of the lamina terminalis, and the subfornical organ.
