When the molecules move from higher concentration to lower concentration, it does not use energy. However, when the opposite movement occurs; the molecules move from a low concentration area to high concentration area, the process uses energy since it takes place against the concentration gradient. These movements are important in order to filter substances, to maintain osmosis balance, to move ions and other substances in and out across the cell membranes, etc.
Among the different movements, osmosis and dialysis are two important processes. Also, both osmosis and dialysis have two types; endosmosis and exosmosis are the two types of osmosis, and the two main types of dialysis are hemodialysis and peritoneal dialysis. Overview and Key Difference 2. What is Osmosis 3. What is Dialysis 4. Similarities Between Osmosis and Dialysis 5.
Osmosis is a type of diffusion in which water molecules or solvent molecules move from a higher concentration region to a low concentration region through a semi-permeable membrane. This process continues till the solute concentration equalizes in both areas. However, in osmosis, the semi-permeable membrane does not allow solutes to move across the membrane. Since water molecules or solvent molecules move along the concentration gradient, it does not require energy.
Hence, it is a passive process that occurs spontaneously. Since osmosis mainly occurs in the cell during the uptake and removal of water from the cell, water molecules move across the plasma membrane, which is semi-permeable.
The movement occurs from a higher water potential to the lower water potential. Based on the direction of movement of water into the cell, osmosis can be divided into two types as endosmosis and exosmosis. The water movement only remains until the two water potentials become equal on both sides of the cell membrane. Dialysis is the main process in the body to remove excess water and solutes from the body. Generally, the kidney is the organ responsible for the removal of excess water, ions, metabolic wastes, and toxins.
It filters around L of fluid per day. This means dialysis is applicable when the kidneys fail to perform their normal function. Osmosis is a very crucial part of the method during the biochemical processes since biological membranes, by nature, are semipermeable.
Huge and extreme molecules like ions similar to the ones of polysaccharides and proteins are impermeable to these membranes. Although non-polar or hydrophobic molecules like lipids, as well as small molecules like Nitrogen, Carbon Dioxide, oxygen, and nitric oxide, are permeable. The movement of a liquid via a semipermeable membrane from a region of low saturation to the zone with a higher concentration of the solute is defined as osmosis.
On the contrary, water is the most typical and the most popular solvent in biological environments. Osmosis can also transpire in other liquids or supercritical liquids, and sometimes even in gases.
The very first dialysis that is recorded to be a successful one was recorded in the year In medical terminology, dialysis is the process that is used to remove excess water, solutes, also toxins from the blood of people whose kidneys cannot function the normal process naturally. When there is an unexpected sudden failure of kidney function, known as an Acute Kidney injury. The phenomenon was earlier known as acute renal failure. Osmosis can also explain the function of osmotic diuretics which are medications allowing them to drain fluids from the brain.
Osmosis and dialysis are two important cellular processes that the scientific and medical community takes into consideration. Osmosis is the flow of a solvent from a lower concentration to a higher concentration while dialysis is the passage of a solute in a permeable membrane. Osmosis can be used in the field of biochemistry and pharmacology while dialysis is used in the field of medicine in helping patients with renal failure excrete their body wastes.
