Human urinary system
The document summarizes the human urinary system. It is comprised of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine, which is 95% water, 2.5% urea, and 2.5% other wastes and salts. The urine is transported from the kidneys to the bladder via the ureters, stored in the bladder, and then expelled from the body through the urethra. The nephrons in the kidneys perform filtration, reabsorption, and secretion to produce urine from blood plasma.
Urinary System 11
This describes the urinary system it's function and explains five abbreviations associated with the urinary system.
Water reabsorbtion
The document summarizes key components and functions of the distal convoluted tubule and collecting duct system in the kidney. It explains that thiazide diuretics inhibit sodium and chloride reabsorption in the distal convoluted tubule. It also describes how the collecting duct system, regulated by aldosterone and antidiuretic hormone, is responsible for 4-5% of sodium and 5% of water reabsorption on average, but can reabsorb over 24% of filtered water during extreme dehydration. Finally, it explains how antidiuretic hormone activates aquaporins in the collecting ducts to reabsorb water and inhibit diuresis.
Kidney127
The urinary system consists of the kidneys, ureters, bladder, and urethra. The kidneys filter waste from the blood to produce urine. Each kidney contains over a million nephrons, the functional units that filter blood. Urine is composed of water and waste products like urea and passes from the kidneys through the ureters to the bladder. Hormones and the nervous system help regulate urine production to maintain fluid balance and blood pressure within tight limits.
Excretory system handout2
The excretory system removes waste from the body through excretion. The kidneys are the main organs of excretion, filtering waste such as urea and excess water and salts from the blood and excreting it as urine. The nephrons are the functional units of the kidneys that filter the blood in a two-step process of filtration and reabsorption, where most of the filtered water and nutrients are reabsorbed but waste remains and becomes urine. Urine is transported from the kidneys to the bladder for storage until excretion.
Furosemide
Diuretics work by preventing the body from absorbing too much salt and increasing the excretion of water and salt in urine. Furosemide is a common diuretic ("water pill") that is prescribed to treat high blood pressure and reduce excess fluid in the body from conditions like heart failure or kidney disease. It works by inhibiting sodium reabsorption in the ascending loop of the kidney, which leads to increased water excretion in urine. Potential side effects include headaches, dizziness, thirst, and electrolyte imbalances.
URINARY SYSTEM. PHYSİCAL
The urinary system functions to maintain homeostasis by filtering the blood and regulating fluid balance, electrolyte and acid-base levels. The kidneys filter blood to form urine through glomerular filtration, reabsorption and secretion. Urine is stored in the bladder and emptied during micturition, which is facilitated by spinal and brain centers.
Homeostasis
The document discusses homeostasis and the roles of the liver and kidneys in maintaining it. The liver regulates blood composition, stores glucose as glycogen, and creates the nitrogenous waste urea. It will test blood vessels involved in digestion for glucose levels before and after eating, hypothesizing the hepatic portal vein will have higher levels after eating. The kidneys filter waste from the blood and regulate water and salt levels through processes like filtration, reabsorption, and secretion in nephrons.

The urinary system consists of organs that produce and excrete urine from the body, including the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine and are located in the abdominal cavity. Nephrons are the functional units of the kidneys that filter waste products from the blood to produce urine. Urine is stored in the bladder and exits the body through the urethra. Common disorders of the urinary system include cystitis, kidney stones, and urinary tract infections. The functions and structures of the urinary system change over the lifespan from childhood to older age.
The urinary system
The urinary system functions to excrete waste from the blood, eliminate waste from other organ systems, regulate water balance and pH levels, and produce hormones. The kidneys filter blood to form urine, which travels through the ureters to the bladder and is eventually excreted through the urethra. Urine formation involves filtration, reabsorption, concentration, and secretion processes in the nephrons. Abnormal constituents in urine can indicate various kidney and urinary tract disorders.
Glomerular Function
The kidneys serve several primary functions related to regulating plasma volume and electrolyte balance. They filter blood to remove wastes and produce urine, while reabsorbing necessary water, electrolytes, and other substances. The complex nephron structure allows for selective reabsorption and secretion to maintain homeostasis. Glomerular filtration and tubular reabsorption/secretion precisely regulate water and electrolyte levels in the blood and production of urine. This helps the kidneys control plasma volume and composition.

The document discusses the excretory system. It describes the major organs that are involved in excretion, including the lungs, skin, liver, and kidneys. The kidneys are described in more detail, noting their location and role in filtering the blood and producing urine. Urine contains waste products like urea, uric acid, and creatinine. The document also outlines other parts of the urinary system like the ureters, urinary bladder, and urethra. It discusses how the excretory system interacts with other body systems and concludes by covering two health issues - kidney stones and cystitis.
.-14 - The renal system.pdf
The kidney plays a central role in homeostasis by filtering the blood to remove waste and regulating fluid, electrolyte and acid-base balance. The functional unit is the nephron, which consists of the renal corpuscle for filtration and renal tubule for modification of the filtrate. There are over 1 million nephrons per kidney consisting of a glomerulus for filtration into the Bowman's capsule and tubule for reabsorption and secretion. The kidneys maintain fluid balance by regulating intake, output, electrolytes and controlling blood pressure through hormone secretion like renin and erythropoietin. Renal failure occurs when filtration declines below 25% of normal capacity, leading to accumulation of waste and fluid overload.
Renal system bundle.pdf
The document provides information about the renal (urinary) system. It describes the anatomy and functions of the kidneys, nephrons, and other structures involved in urine formation and excretion. It discusses urine production and the role of the kidneys in maintaining fluid, electrolyte, and acid-base balance. Common kidney problems like urinary tract infections and glomerulonephritis are also summarized.
Urinary System human anatomu and physiology 2 .pptx
The primary job of the urinary system is to filter blood, producing urine as a waste product in the process. The renal pelvis, bladder, urethra, ureters, and kidneys are the organs that make up the urinary system. The nutrients in meals are transformed by the body into energy.The kidneys secrete urine, which is a liquid waste product. The fluid known as urine is translucent and clear, typically with an amber tint. An average person excretes five to eight cups, or forty to sixty ounces, of pee in a 24-hour period. Urine is mostly composed of salt, urea, and uric acid in a watery solution.The kidneys, ureters, bladder, and urethra make up the human urine system, sometimes referred to as the urinary tract or renal system. The elimination of waste from the body, blood volume and pressure regulation, electrolyte and metabolite level control, and blood pH regulation are all functions of the urinary system. The body's drainage system for eventually eliminating urine is the urinary tract.[1] Via the renal arteries, which exit the kidneys through the renal vein, the kidneys receive a substantial blood supply. Nephrons are the functional units that make up each kidney. Wastes (in the form of urine) leave the kidney through the ureters, tubes composed of smooth muscle fibres that direct urine into the bladder, where it is collected and processed further.The organs that generate urine and carry it to the excretory site are referred to as the urinary system. The kidneys are situated in the space between the parietal peritoneum and the dorsal body wall on both the left and right sides of the human urinary system.The kidney's functional unit, the nephrons, is where urine is first formed. After that, urine travels via the nephrons and the collecting ducts, a network of convergent tubules. The minor and major calyces that eventually connect to the renal pelvis are formed by the union of these collecting ducts. Urine then proceeds from the renal pelvis into the ureter, where it is transported to the bladder. Males and females have different urinary system anatomy, specifically in relation to the urine bladder. The prostatic, membranous, bulbar, and penile urethras in men are formed by the urethra's progression from the internal urethral aperture in the bladder's trigone via the external urethral orifice. The urine leaves the body through the external meatus of the urethra. The female urethra, which starts at the neck of the bladder and ends in the vaginal vestibule, is substantially shorter.Bowman's capsule filters blood entering the tubules from the circulatory system in the first segment of the nephron. Filtration across a semipermeable membrane is facilitated by gradients of osmotic and hydrostatic pressure. Water, ions, and tiny molecules that easily flow through the filtering membrane make up the filtrate. However, the filtration barrier blocks the passage of bigger molecules like proteins and blood cells. The glomerular filtration rate, or GFR, is the volume

- 2. Chapter 14
- 3. Applied Learning Outcomes Use the terminology associated with the urinary system Learn about the following: • Organs and structures of the urinary system • Physiology of the urinary system Understand the aging and pathology of the urinary system Chapter 14 – The Urinary System
- 4. Overview The urinary system plays a major role in in the removal of wastes to maintain homeostasis. It acts as a filtering system of the blood. It not only removes wastes, it maintains the pH level, electrolyte composition, and water content of the blood. Chapter 14 – The Urinary System
- 5. Gross Anatomy of the Urinary System Chapter 14 – The Urinary System
- 6. Urine Voiding Micturition (urination) involves both reflexive and voluntary control. The detrusor muscles of the bladder respond to pressure in the bladder by contracting and forcing urine into the opening of the internal urethral sphincter. The sphincter relaxes and allows urine to exit the bladder. It flows through the urethra to the body’s exterior. Chapter 14 – The Urinary System
- 7. The Nephrons • Perform all of the physiological functions of the urine formation • Composed of an integral complex of blood vessels and renal tubules Chapter 14 – The Urinary System
- 8. Urine Formation Urine is formed in three stages: • Glomerular filtration • Tubular reabsorption • Tubular secretion Chapter 14 – The Urinary System
- 9. Hormonal Regulation of Urine Formation Antidiuretic hormone (ADH) reduces diuresis, or water excretion, and helps to prevent dehydration. Atrial natriuretic factor (ANF) is produced by special cardia cells; its purpose is to lower blood pressure by reducing blood volume through increased diuresis. Angiotensis II elevates blood pressure through vasoconstriction; the consequent increase in pressure within the glomerular capillaries increases filtration and elevates urine output. Chapter 14 – The Urinary System
- 10. Wellness and Illness over the Life Span Most urinary system disorders involve malfunction of the renal system, while others involve the structures of the conducting system. Urinary disorders are categorized as the following: congenital, infection/inflammation, immune, hormonal, degenerative, tumor. Health conditions are major contributors to any age- related decrease in urinary function. Chapter 14 – The Urinary System
- 11. Summary The urinary system removes waste to maintain homeostasis, acts as a filtering system of the blood, and maintains the pH level, electrolyte composition, and water content of the blood. All organs and structures of the urinary system can be invaded by bacteria, resulting in infection and inflammation. Components of the urinary system involved in proper urine voiding are more likely to be affected by the aging process. Chapter 14 – The Urinary System
Editor's Notes
- The kidneys, ureters, urinary bladder, and urethra are the organs and structures that make up the urinary system. Kidneys: The organs that form urine; positioned on either side of the midline of the superior abdominal cavity Ureters: Tubes that send urine from the kidneys to the bladder; one extends from each hilus and runs inferiorly to transport urine to the urinary bladder for temporary storage Urinary Bladder: A sac-like organ that serves as a reservoir for urine storage Urethra: The tube that transfers urine from the bladder to the body’s exterior
- The nephrons’ tubular system consists of Bowman’s capsule, the proximal and distal convoluted tubules, the loop of Henle, and the collecting tubule. The blood vessel component of the nephrons begins with the afferent arteriole, narrows to form the glomerulus within Bowman’s capsule, exits via the efferent arteriole, and ends with the peritubular capillary system.
- Glomerular Filtration: The process by which plasma and many dissolved substances are moved from the blood into Bowman’s capsule Tubular Reabsorption: A process in the peritubular capillary system in which water, nutrients, and electrolytes travel back into the blood Tubular Secretion: The process by which certain waste products and ions are removed from the blood into the tubular fluid
- Vasoconstriction: Constriction of the blood vessels
