The mucus secreted by the wall of the stomach resists the action of HCl on itself. 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 Understanding the physiological pH buffering system is important. By the end of this process, the filtrate in the tubule has become urine containing only water, waste products, and excess ions. Nephron are structural and functional unit of kidneys i.e. Other constituents include urea, chloride, sodium, potassium, creatinine and other dissolved ions, and inorganic and organic compounds. a. Aldosterone: secreted by the cells of the adrenal cortex. Urine is a liquid by-product of the body secreted by the kidneys through a process called urination and excreted through the urethra. The urine produced is 95% water and 5% nitrogenous wastes. It consists of a tubule which is connected with a collecting duct at one end and a cup shaped structure at the other end, called Bowmans capsule. Digoxin is a well-known cardiac glycoside and one of the oldest drugs used today in cardiovascular medicine.

Urine formation is broadly divided into three steps:-Filtration; Reabsorption; Collection

Finally, Henles loop or nephron tubule originates from the proximal tubule that descends into a thin limb (2-14 mm long) and goes upward, forming a thick limb (12 mm long). The net result is for every one molecule of H + secreted, one molecule of bicarbonate and Na + is reabsorbed into the blood stream. Urine is a liquid by-product of the body secreted by the kidneys through a process called urination and excreted through the urethra. An electrolyte is a compound that dissociates into ions when dissolved in water. Normal physiological pH is 7.35 to 7.45.

Describe how the nephron is the functional unit of the kidney and explain how it actively filters blood and generates urine K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood. By the end of this process, the filtrate in the tubule has become urine containing only water, waste products, and excess ions. products called hormones are secreted directly into the fluid bathing the gland. Manipulation of the urine pH can enhance the excretion of acidic or basic chemicals through a mechanism known as ion trapping. The major pH buffer system Within the excretory system of many organisms, this is important for both waste removal and acid-base balance. Aldosterone from the adrenal cortex promotes active tubular secretion of potassium ions in the late distal convoluted tubule (DCT) and collecting ducts. ii. B. Hydronium ions are secreted into the fi ltrate, where they are buffered by bicarbonate ions in the fi ltrate. In the large intestine, there is a net absorption of sodium ions and chloride ions are actively absorbed. The nephron controls water by movement of sodium chloride in and out of the filtrate and the water will follow sodium depending on the osmotic gradient. Their main function is to provide protection against chemical and mechanical stresses.

a. Aldosterone: secreted by the cells of the adrenal cortex. Nephron is the basic filtration unit in the kidney. Wastes such as urea, ammonia, and creatinine are excreted in the urine. The formation of urine happens under three major processes that occur in the excretory system: filtration, reabsorption, and secretion. It has wide-ranging beneficial effects and continues to play an important role in the contemporary management of appropriately selected patients with heart failure and atrial fibrillation. Compound epithelium is made of more than one layer (multi -layered) of cells and thus has a limited role in secretion and absorption (Figure 7.3). Describe the structure and functioning of nephron.
