Ion transport along the nephron is essential for the reabsorption of sodium and water, maintenance of plasma volume and blood pressure and production of urine the loop of henle contributes to the absorption of approximately 25% of filtered sodium and can be targeted by diuretic therapy.

Renal system - human excretion: the kidney has evolved so as to enable humans to exist on land where water and salts must be conserved, wastes excreted in concentrated form, and the blood and the tissue fluids strictly regulated as to volume, chemical composition, and osmotic pressure. A nephron is the filtering unit of the human kidneys, and its job is to regulate the concentration of water and soluble substances by filtering the blood the nephron reabsorbs what the body needs to function and then excretes the rest as urine the nephrons work through a two-step process the. -from the renal corpuscle, filtrate enters the tubular passageway of the nephron, which reabsorbs organic substrates and vitamins, water and electrolytes, secrete waste products -from the tubular passageway of the nephron fluid enters into the collecting system (collecting system are tubes that carry tubular fluid away from the nephron. Structure of a kidney nephron: basic diagram of a kidney nephron, as taught for a-level human biology, itec anatomy & physiology, and as part of the basic training for some therapies, eg massage, aromatherapy, acupuncture, shiatsu.
The nephron is a regulatory unit in the body regulating the body fluid composition through filtering and reabsorbing materials as the waste products move through the system of tubules. The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys the kidneys make urine by filtering wastes and extra water from. The nephron is the fundamental functional unit of the kidney and can be thought of as a long tube of variable thickness which winds a set path through the kidney most of the macroscopic physiological function of the kidney is simply the result of the combined action of nearly a million individual nephronic units. Physiology of the kidneys water and metabolic waste molecules during the process of renal system filtration in the nephron may be either a passive or active.
Its functions are vital to life and are regulated by the endocrine system by hormones such as antidiuretic hormone, aldosterone, and parathyroid hormone each nephron is composed of an initial filtering component (the renal corpuscle) and a tubule specialized for reabsorption and secretion (the renal tubule.

The nephron is the main functional unit of the kidney which is responsible for filtering the blood and concentrating the solution to produce urine in the process, macronutrients, electrolytes and the required amount of water are retained while waste substances, excess electrolytes, micronutrients and toxins are expelled. The nephron system is a proven japanese system that works like a mechanical kidney dirty oil is filtered swiftly and efficiently, yielding purified, fully recycled. The urinary system is comprised of the kidney, ureter, urinary bladder, and urethra the kidney produces urine, which contains excess water, electrolytes and waste products of the body it then flows down the ureter into the bladder where it is temporarily stored. The nephron consists of a renal corpuscle, proximal tubule, loop of henle, distal tubule, and collecting duct system (figure 2-2) the renal corpuscle consists of glomerular capillaries and bowman's capsule.
