Description

Physiology is the scientific study of how a biological organism works and how its mechanisms work. Physiology is a branch of biology that focuses on how animals, organ systems, specific organs, cells, and biomolecules perform the chemical and physical processes necessary for a living system to function. The field can be separated into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology in accordance with the types of organisms. Biophysical and metabolic processes, homeostatic regulatory systems, and cell-to-cell communication are essential for physiological function. While pathological state refers to aberrant situations, especially human diseases, physiological state is the condition of normal function.

The study of renal physiology is known as Kidney physiology that includes all kidney functions like maintaining acid-base balance, controlling fluid balance, controlling sodium, potassium, and other electrolytes, eliminating toxins, absorbing glucose, amino acids, and other small molecules, controlling blood pressure, producing different hormones like erythropoietin, and triggering vitamin D. Renal Physiology is a three fundamental functions are such as filtration, reabsorption and secretion.

The nephron is the smallest functional unit in the kidney, it is level at renal physiology is much investigated. The blood entering each nephron is first filtered before it enters the kidney. Following that, this filtrate travels the entire length of the nephron, a tubular organ lined with a single layer of specialised cells and encircled by capillaries. These lining cells’ primary roles include secreting waste from the blood into the urine and reabsorbing water and small molecules from the filtrate into the blood. The kidney needs to receive and appropriately filter blood in order to operate properly. Many millions of filtration units termed renal corpuscles, which is made up of a glomerulus and a Bowman’s capsule, that is carry out this function at the microscopic level. Estimating the rate of filtration is also known as glomerular filtration rate, and allows for a general evaluation of renal function. Removing waste materials from the body is one of the kidneys’ many tasks as a potent chemical factory. Drug removal from the body the fluid balance of the organism.

Reabsorption is a process by which solutes and water are taken out of the tubular fluid and transferred into the blood is known as tubular reabsorption. Reabsorption is rather than absorption which is used, because the body is recovering these compounds from a postglomerular fluid stream, that is on its way to becoming urine and these substances have already been absorbed. Reabsorption is a two-step process that starts with the active or passive removal of compounds from the tubule fluid into the renal interstitium (the connective tissue surrounding the nephrons), and then the transportation of these molecules into the bloodstream.

Secretion is a chemical substance that is emitted from a cell or gland is an example of a secretion, the movement of material from one place to another. The removal of certain compounds or waste products from a cell or organism is known as excretion. Porosomes is act as secretory portals at the plasma membrane, are the standard method of cell secretion. Secretory vesicles transiently dock and fuse in porosomes, which are long-lasting cup-shaped lipoprotein structures implanted in the cell membrane. This allows the release of intravesicular contents from the cell.
