Functions of kidney
The nephron is the functional unit of the kidney, which filters blood to form urine. The nephron contains a glomerulus that filters the blood and a renal tubule that reabsorbs most of the filtered water and solutes. Key functions of the nephron include filtering the blood at the glomerulus and reabsorbing various substances like water, glucose, amino acids, salts, and urea along different portions of the renal tubule under hormonal control. The kidney plays an important role in regulating fluid and electrolyte balance, excreting wastes, and producing hormones.

The document provides an overview of renal physiology:
1. It describes the anatomy and functional units of the kidneys, including nephrons and their role in filtering blood and regulating water, electrolyte and waste balances.
2. The key functions of the kidneys are explained as regulating fluid and ion balances, excreting wastes, and secreting hormones like erythropoietin and renin.
3. The processes of glomerular filtration, tubular reabsorption and secretion are summarized as the basic mechanisms by which the kidneys form urine through balancing filtration, reclamation of needed substances, and removal of wastes.
Structure of nephron and functions of its parts
The nephron is the structural and functional unit of the kidney that filters blood to form urine. It consists of a renal corpuscle containing the glomerulus and Bowman's capsule, and renal tubules. The glomerulus filters blood to form filtrate, which passes through three segments of the tubules - the proximal convoluted tubule, loop of Henle, and distal convoluted tubule. These tubule segments reabsorb essential substances and further concentrate the filtrate through selective reabsorption and secretion to produce urine and maintain electrolyte and pH balance.
Gfr(glomerulur) filtration rate and its regulation
The kidneys are located in the abdominal cavity, with the left kidney slightly higher than the right. Each kidney contains approximately 1 million nephrons, the functional units that filter blood. The glomerulus is a ball of capillaries in each nephron that filters about 3-4 liters of blood per minute, producing 125 ml of filtrate per minute called glomerular filtration. Filtration occurs through endothelial cells in capillaries, the basement membrane, and epithelial cells lining Bowman's capsule. Key factors in filtration include hydrostatic and oncotic pressures between the glomerulus and Bowman's capsule, maintaining a net filtration pressure of 8 mmHg for fluid to pass from the glomerulus
Histology of kidney.pptx

Renal function test
The document discusses renal circulation, regulation of renal blood flow, nephron anatomy and physiology, and effects of various drugs on renal function. The key points are:
1) The kidneys receive 20-25% of cardiac output despite only weighing 0.4% of body weight. Renal blood flow is regulated by neural, hormonal and local factors to maintain glomerular filtration.
2) Nephrons contain a loop of Henle that acts as a countercurrent multiplier to concentrate urine by establishing an osmotic gradient in the renal medulla, aided by countercurrent exchange in vasa recta capillaries.
3) Drugs like NSAIDs, ACE inhibitors, intravenous agents
Urine formation function of kidney
The document summarizes the key structures and mechanisms involved in urine formation by the kidneys. The glomeruli, proximal canaliculi, and distal canaliculi are responsible for filtration, reabsorption, and secretion to form urine. Filtration occurs as blood is filtered in the glomeruli, producing primary urine. Most of the filtered substances are then reabsorbed back into the bloodstream in the canaliculi. Remaining substances and waste are excreted in the final urine output, with the kidneys processing around 180 L of blood filtrate per day.
Kidney structure (anatomy)
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
Physiology of Urine Formation
This document provides an overview of urine formation (uropoeisis) through glomerular filtration, tubular reabsorption, and tubular secretion in the nephrons of the kidney. Key points include: ultrafiltration occurs due to differences in blood pressure in the glomerular capillaries, allowing filtration through fenestrations into Bowman's capsule. Tubular reabsorption selectively reabsorbs substances like glucose, amino acids, electrolytes, and water. Tubular secretion actively transports waste products from the blood into the urine. The normal characteristics, composition, and daily output of urine in humans is also summarized.
Endocrine function of kidney
The kidney plays an important endocrine role by secreting several hormones. The document discusses four key hormones secreted by the kidney: erythropoietin, calcitriol, thrombopoietin, and renin. Erythropoietin stimulates red blood cell production. Calcitriol helps absorb calcium. Thrombopoietin stimulates platelet production. Renin regulates blood pressure through the renin-angiotensin system. The kidneys secrete these hormones through specialized cells like the juxtaglomerular cells and extraglomerular mesangial cells to perform critical functions in the body.

Cells are the basic building blocks of the body. They were first discovered in the 17th century with the invention of the microscope. The cell theory states that cells are the smallest living units, all new cells come from preexisting cells, and cells contain specialized structures that allow them to carry out life processes. A typical cell contains a plasma membrane, cytoplasm with organelles, and a nucleus containing DNA. The plasma membrane regulates what enters and exits the cell while organelles like the ER, Golgi, mitochondria, and lysosomes carry out specialized functions within the cell.

Kidney (STRUCTURE AND FUNCTIONS) (: The Guyton and Hall physiology)
STRUCTURE AND FUNCTIONS OF KIDNEY
There are two kidneys in body , Rt & Lt, lying on post abdominal wall, outside peritoneal cavity.
There weight is aprx. 150 Gm and size is clenched fist.
On medial side, there is a region called hilum through which pass blood & lymphatic vessels, nerve fibers and ureterKidney is surrounded by a protective fibrous capsule.
Each kidney has two major zones, outer thick known as cortex and part known as medulla.
Medulla is divided into multiple cone shaped tissue masses called renal pyramid.
The base of pyramid begins at junction of cortex & medulla and terminates in papilla which projects into space of renal pelvis.
Renal pelvis is funnel shaped continuation of upper end of ureter.
1- Excretion of metabolic waste products such as urea, creatinine, uric acid, Bilirubin, hormones & drugs.
2-. ELIMINATE HARMFUL FOREIGN COMPOUNDS.
Such as toxins, drugs, heavy metals, pesticides.
3- Regulation of water & electrolyte balance to maintain normal homeostasis of body by re-absorption and adjustment of rate of excretion of various substances.
4- Regulation of Arterial Pressure.
*Long term regulation by excreting variable amounts of water and sodium
and
*short term by secreting vaso-active substance (renin).
Kidney function and nephrons
The nephron is the functional unit of the kidney that filters blood to form urine. Glomerular filtration occurs when blood plasma filters through the glomerulus into the nephron tubules. Reabsorption and tubular secretion then alter the filtrate's composition as it travels through the tubules. Reabsorption moves substances like water, ions, and glucose from the filtrate back into blood to concentrate the urine. Tubular secretion actively transports substances like hydrogen ions and potassium into the filtrate. Together these processes determine the final volume, concentration and composition of urine to regulate blood chemistry and remove waste.
Anti Diuretic Hormone(ADH).ppt
Vasopressin, also known as anti diuretic hormone (ADH), is secreted by the hypothalamus and stored and released by the posterior pituitary gland. It acts to conserve water in the body by increasing the permeability of collecting tubules and ducts in the kidneys to water absorption. ADH also causes vasoconstriction which increases blood pressure. Its secretion is regulated by factors like sodium concentration, blood volume, and blood pressure in order to maintain fluid homeostasis. Disorders of ADH secretion can cause diabetes insipidus, characterized by excessive urine production and thirst.
Kidney anatomy, physiology and disorders
The kidneys are essential excretory organs that filter waste from the blood to produce urine. The kidneys contain over 1 million tiny filtering units called nephrons. Blood enters nephrons via the glomerulus and is filtered, then most water and nutrients are reabsorbed. The loop of Henle and countercurrent mechanism allow concentration of urine. Hormones regulate water and electrolyte balance. The kidneys maintain acid-base balance and blood pressure while filtering wastes and drugs for excretion. Kidney disorders occur if filtration, reabsorption or other functions are disrupted.
urine concentration and dilution
The document discusses the formation of concentrated urine through a countercurrent system and urea recycling in the kidneys. It explains that concentrated urine is formed through (1) high levels of ADH hormone and (2) development and maintenance of a hyperosmotic renal medullary interstitium. This gradient is established through a countercurrent system using the loop of Henle and vasa recta blood vessels, as well as urea recycling back into the medulla. Sodium and other solutes are deposited in the medulla through these mechanisms to draw water out of the urine as it passes through the kidneys, resulting in highly concentrated urine.
Urinary System
This document provides an overview of the anatomy and physiology of the urinary system. It describes the key components - kidneys, ureters, bladder, and urethra. It discusses the internal anatomy of the kidneys including the cortex, medulla, nephrons, and blood supply. It also summarizes kidney functions like filtration, reabsorption, and regulation of water, electrolytes and acid-base balance. Physiological concepts like glomerular filtration rate and the mechanisms of filtration and tubular transport are explained as well.

The document provides an overview of the urinary system, including its main organs and functions. It describes the anatomy and histology of the kidney, nephron, ureters, and urinary bladder. It explains the three main processes of urine formation - glomerular filtration, reabsorption, and secretion. It also discusses some common urinary tract diseases and the relationships between the urinary system and other body systems.
Anatomy and Physiology of Urinary System
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine. The urine passes from the kidneys to the bladder via the ureters. The bladder stores urine until micturition. The urethra then carries urine out of the body. The urinary system regulates water balance and the levels of electrolytes, acids, and bases in the blood to maintain homeostasis. Nephrons are the functional units of the kidneys that filter blood and form urine through processes like filtration, reabsorption, and secretion.

Urine formation and micturition
The document summarizes urine formation and micturition. Urine is formed through glomerular filtration in the kidneys where water and small molecules pass through the glomerular membrane into the filtrate. Most of the filtrate is reabsorbed in the renal tubules, with less than 1% excreted as urine. Micturition is the process of emptying the bladder through contraction of the detrusor muscle and relaxation of the internal urethral sphincter.
RENAL HORMONES
This document discusses the endocrine functions of the kidney, including the production of hormones like renin, erythropoietin, and vitamin D. It describes the renin-angiotensin system and how juxtaglomerular cells in the kidney secrete renin in response to changes in salt concentration or blood pressure. It also explains how the kidney regulates glomerular filtration rate through auto-regulation, hormonal factors, and nervous control. Additional kidney hormones discussed include erythropoietin, which regulates red blood cell production, and vitamin D, which is activated in the kidney to its active form.
Kidney function
The kidney has four main functions:
1. Excretory - forms and excretes urine through glomerular filtration, reabsorption, and secretion
2. Homeostatic - regulates blood volume, pressure, pH and electrolyte concentrations
3. Endocrine - produces hormones like erythropoietin, renin, and prostaglandins
4. Metabolic - performs gluconeogenesis during starvation and metabolizes hormones

The kidney also helps regulate blood pressure and produces hormones that help make red blood cells and activate vitamin D.
Kidney structure & function
The kidney is made up of approximately 1 million filtering units called nephrons. Each nephron contains a glomerulus for initial blood filtration and a tubule for reabsorption and waste excretion. The kidneys play crucial roles in regulating blood pressure, electrolyte balance, and removing waste from the blood in the form of urine. Common kidney functions include filtering the blood, reabsorbing necessary nutrients, and secreting hormones to support other bodily processes. Damage to the kidneys can impair these functions and potentially lead to serious health issues like kidney failure.
Kidney Power Point Presentation
The kidney plays a vital role in filtering waste from the blood and maintaining electrolyte balance. It is located in the back of the abdominal cavity, with each person having two kidneys. The functional unit of the kidney is the nephron, which contains the filtration membrane that filters the blood to form urine by removing waste and regulating electrolytes. Kidney failure requires dialysis to filter the blood until a kidney transplant can be received.

Anatomy of the kidney
The kidneys are located behind the peritoneum in the posterior abdomen, one on each side of the spine. The kidneys filter blood, remove waste through urine production, secrete hormones, and regulate fluid and electrolyte balance. Each kidney has an anterior and posterior surface, an upper and lower extremity, and a medial and lateral border. The kidneys receive their blood supply from the renal arteries, which branch into smaller arteries within the kidneys.
Renal Physiology
The document provides an overview of renal physiology and the structure and function of the kidney and nephron. It describes the kidney as a bean-shaped organ that filters blood to produce urine and removes wastes. The nephron is the functional unit of the kidney, consisting of a glomerulus and tubules (proximal convoluted tubule, loop of Henle, distal convoluted tubule and collecting duct) that work together to regulate water and electrolyte levels via selective reabsorption and secretion processes along different portions of the tubule. The loop of Henle plays a key role in concentrating urine by establishing an osmotic gradient in the kidney medulla.

Renal physiology introduction.
This document provides an overview of renal physiology, covering the following key points in 3 sentences:
The kidneys have excellent blood supply and filter plasma to remove waste and regulate water/ion balance through processes of glomerular filtration, tubular reabsorption and secretion; the nephron is the functional unit where filtration occurs at the glomerulus and capillaries aid reabsorption; precise control of filtration, reabsorption of substances like sodium, glucose and water, and secretion of potassium allows the kidneys to maintain electrolyte and fluid homeostasis.
CME: Kidney - Anatomy & Physiology
The document summarizes kidney anatomy and physiology. It discusses the embryonic development of the kidney starting from the pronephros, mesonephros, and metanephros. It describes the gross anatomy of the kidney including its position, size, cortex, medulla, renal sinus and blood supply. It also provides an overview of renal physiology including glomerular filtration, tubular reabsorption and secretion, measurement of GFR, autoregulation, and the renin-angiotensin system.
Urinary system
The urinary system consists of two kidneys, two ureters, one urinary bladder, and one urethra. The kidneys filter the blood and produce urine by regulating ions, volume, pH, and producing hormones. Urine passes from the kidneys to the bladder via the ureters. The bladder stores urine which is then expelled through the urethra. The functional unit of the kidney is the nephron, which filters blood and reabsorbs needed substances while secreting waste for urine production.
Anatomy and physiology of urinary system
The document provides an overview of the anatomy and physiology of the urinary system. It describes the key components - kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to form urine. The ureters then transport urine from the kidneys to the bladder. The bladder stores urine until voiding. During urination, urine is expelled through the urethra. Together these structures precisely regulate chemical levels in the body and remove waste.
Anatomy and Physilogy of Urinary System (Renal System)
The urinary system is responsible for filtering blood and producing urine. The kidneys filter waste from the blood to form urine, while regulating water and electrolyte levels. Urine travels from the kidneys through ureters to the bladder, where it is stored until excreted through the urethra. The key parts are the kidneys, which contain nephrons that filter blood and reabsorb necessary substances; ureters, which transport urine from kidneys to bladder; and bladder, which stores urine until excretion. Together this system eliminates wastes and regulates fluid and electrolyte balance in the body.

Structure of kidney
This document provides an overview of kidney anatomy and function. The kidney has two main roles - purifying the blood and expelling urine. It has a bean shape and is located in the abdominal cavity behind the muscles. The kidney contains a cortex on the outer part with micro filters, a medulla on the inner part with collecting ducts, and pyramids where the ducts open. Renal arteries carry blood into the kidney while renal veins carry blood out, and urine is collected in the pelvis before exiting through the ureters to the bladder.

Body fluid compartments slide share
The human body is composed primarily of fluids, with water making up about two-thirds of the total body weight. The body's fluids are divided into two main compartments: intracellular fluid (ICF) and extracellular fluid (ECF). ICF makes up about 40% of total body water and is contained within cells, while ECF comprises around 20% and includes interstitial fluid, plasma, and transcellular fluids such as cerebrospinal fluid. ECF volume can be measured using substances that remain in the extracellular space, while total body water and plasma volume are determined through the dilution of markers distributed throughout the body's water compartments. Proper fluid balance is essential for acid-base regulation, electrolyte levels

- 13. SELECTIVE REABSORPTION Proximal convoluted tubule Returning substances to the blood Active uptake Requires energy Co-transport Passive uptake Endocytosis
- 15. The Kidneys receive 20-25% of the total output of the heart filter 170 000 cm3 filtrate a day reclaim 1300 g of NaCl each day 180 g glucose each day almost all the water (180 litres) that is filtered each day produce 1200 to 2000 cm3 urine a day expect to carry out calculations on these sorts of figures
