- adh controls the volume of urine by regulating the amount of water absorbed into the convoluted tubules. . At some point ,change in blood level activates the osmoreceptors in the hypothalamus which in turn activates the release of antidiuretic hormone(ADH).

MADMAN BIOLOGY Best Answer: Aldosterone. a hormone, secreted by the adrenal cortex, that maintains normal blood volume, promotes sodium and water retention, and increases urinary excretion of potassium and hydrogen ions.

Ch 11 Review Body system that includes the kidneys, ureters, bladder, and urethra. Its function is to produce urine. It also helps regulate the internal environment of the body by secreting the enzyme renin and the hormone erythropoietin.

urine the fluid secreted by the kidneys, transported by the ureters, stored in the bladder, and voided through the urethra. Normal urine is clear, straw-colored, and slightly acid; has the odor of urea; and has a specific gravity between 1.003 and 1.035.

- C. Regulation of Water Output. 1  Obligatory water losses - insensible water loss from lungs and through skin, undigested food, feces, and urine. 2  Kidneys can concentrate urine, but only a minimum of 500 ml of water is lost in urine/day and therefore concentration and volume of urine excreted depends on fluid intake.

Urinary system The kidney engages in all of the following activities. secreting a hormone which assists in blood pressure regulation. eliminating nitrogenous wastes. secreting a hormone which increases red blood cell production.

Picture of the Bladder The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys, and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and voluntary.The bladder is lined by layers of muscle tissue that stretch to accommodate urine.The normal capacity of the bladder is 400 to 600 mL.uring urination, the bladder muscles contract, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Because it passes through the penis, the urethra is longer in men (8 inches) than in women (1.5 inches).

- Urine Concentration. One of the primary functions of the kidney is better understood at the level of the nephron. In forming urine, the nephron functions to remove metabolic wastes from blood while regulating the volume and composition of body fluids.

Human Physiology/Print Version Direct control of water excretion in the kidneys is exercised by vasopressin, or anti-diuretic hormone (ADH), a peptide hormone secreted by the hypothalamus. ADH causes the insertion of water channels into the membranes of cells lining the collecting ducts, allowing water reabsorption to occur. Without ADH, little water is reabsorbed in the collecting ducts and dilute urine is excreted.

- The urinary system consists of the kidneys, ureters, urinary bladder, and urethra.The kidneys filter the blood to remove wastes and produce urine.The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a plumbing system to drain urine from the kidneys, store it, and then release it during urination.t the same time that the sphincters relax, the smooth muscle in the walls of the urinary bladder contract to expel urine from the bladder. Production of Hormones. The kidneys produce and interact with several hormones that are involved in the control of systems outside of the urinary system. 1  Calcitriol.

- Vasopressin regulates the body's water retention. It is released from the brain when the body is dehydrated and causes the kidneys to conserve water, thus concentrating the urine and reducing urine volume. At high concentrations, it also raises blood pressure by inducing moderate vasoconstriction.

Renal function Alters the volume and composition of blood. Effect of urine production on the body's needs. If body is getting dehydrated and needs more water, kidneys will retain more water and make a smaller volume, more concentrated urine. If the body has too much water, the kidneys will excrete a larger, more dilute urine. Parts of the nephron.

- Osmotic diuretics freely pass by filtration into the filtrate, and they undergo limited reabsorption by the nephron. These diuretics increase urine volume by elevating the osmotic concentration of the nephron, thus reducing the amount of water moving by osmosis out of the nephron.

What are three hormones that regulate the urine volume State where each is made and the specific effect on urine volume?

Control of Blood Pressure The kidneys provide a hormonal mechanism for the regulation of blood pressure by managing blood volume. The renin‐angiotensin‐aldosterone system of the kidneys regulates blood volume. In response to rising blood pressure, the juxtaglomerular cells in the kidneys secrete renin into the blood.

- The ureter is the tube through which urine moves from the kidney to the bladder. A diagram of a kidney. The renal tubule is part of the filtration system in the nephrons of the kidneys. The distal convoluted tubule helps regulate the pH of the urine by secreting positively charged protons. The kidney contains 4 million nephrons, which are responsible for filtering the blood.

- Urine volume is normally measured as a part of test that measures the amount of a substances passed in your urine in a day, such as: 1  Creatinine. 2  Sodium. 3  Potassium.

The Urinary System: Nephron & Urine Formation Besides Urine Formation, the kidney has the following functions: Plays a major role in regulating blood volume because it controls the amount of water to be excreted and the amount of water to be reabsorbed. Regulates electrolytes in the blood by controlling the secretion and reabsorption of sodium and potassium ions.

How does the hormone ADH control urine volume and concentration?

At some point ,change in blood level activates the osmoreceptors in the hypothalamus which in turn activates the release of antidiuretic hormone(ADH).

- The prostate has several functions. 1  It manufactures and stores a portion of the seminal fluid in the acini. This fluid provides lubrication, protects the sperm, and has an antibacterial effect. 2  It blocks the flow of urine during sex and insures that the seminal fluid flows in the correct direction. It delivers its portion (1/6) of seminal fluid during sex by contraction of the smooth muscle in the prostate. It acts as a junction for seminal fluid produced by the seminal vesicles and testicles.

Bladder Dysfunction The sympathetic nervous system regulates the process of urine storage in the bladder. In contrast, the parasympathetic nervous system controls bladder contractions and the passage of urine. The somatic efferent system permits voluntary control over the external periurethral sphincter.

- Describe the hormonal controls of water output in urine. The kidney must normally flush 600 mmol per day of urine solutes out of the body in water. The maximum concentration of urine is about 1200 mOsm, so a minimum of 500ml of water must be excreted.
