Urinary System Practice Exam

To get rid of waste material from the blood, tissues, or organs by a normal discharge (such as sweat, urine, or stool) (National Cancer Institute, n. ). Ureter → urinary bladder → urethra. Discover common diseases, disorders, and procedures related to the urinary system. Site where tubular reabsorption and secretion occur. It also sits slightly lower to make room for the liver located on the right side of your body. Regulation of Nitrogen Wastes. The volume of urine that the adult bladder can collect and hold can range from nearly zero to 600 mL, so the makeup of this tissue must allow it to be adaptable. It is within the peritubular capillaries that reabsorption and secretion will take place. Consists of the macula densa and juxtaglomerular cells. Since the external urinary sphincter is voluntary skeletal muscle, actions by cholinergic neurons maintain contraction (and thereby continence) during filling of the bladder.

Chapter 15 Urinary System Answer Key Lime

The thick muscular layer of the ureter consists of both longitudinal and circular smooth muscles that create the peristaltic contractions to move the urine into the bladder without the aid of gravity. Physiology (Function) of the Urinary System. Some constituents of glomerular filtrate (e. glucose, amino acids) do not normally appear in urine because they are completely reabsorbed unless blood levels are excessive. A sensitivity test indicates which antibiotics will be effective in treating the infection (Sinawe & Casadesus, 2021; MedlinePlus, 2021). However, relaxation of the external sphincter may not be possible in all cases, and therefore, periodic catheterization may be necessary for bladder emptying.

The smooth muscle in the wall of the urinary bladder. Ketone bodies – produced by the disintegration of excess fatty acids in the liver. Definition of urologist. Innervation is the same in both males and females. The kidneys and ureters are completely retroperitoneal, and the bladder has a peritoneal covering only over the dome.

The Urinary System Answer Key

Renal cell carcinoma is a cancer occurring in the kidney tubes where urine is produced or collected. There are three areas of tissue that can be distinguished when a longitudinal section of the kidney is viewed with the naked eye (Fig. For more information, visit the National Institute of Diabetes and Digestive and Kidney Diseases' web page on kidney transplant. The bladder is partially retroperitoneal (outside the peritoneal cavity) with its peritoneal-covered "dome" projecting into the abdomen when the bladder is distended with urine.

Name the four regions of the renal tubule: a. proximal convoluted tubule. These resemble a coiled tuft and are shown in Figure 13. Which of the following is not considered a loop diuretic? Centers for Disease Control and Prevention. 9 The glomerulus and glomerular capsule. The kidneys must produce a minimum urine volume of about 500 mL/day to rid the body of wastes. As the segmental arteries continue to branch, blood flows into the interlobar arteries, which pass through the renal columns and extend to the cortex. This takes place through the semipermeable walls of the glomerulus (Fig. 00) due to the presence of solutes. Endocrine Urinary Function. The male urethra (Figure 25. As blood passes through the glomerulus, 10 to 20 percent of the plasma filters through small spaces between the cells of the glomerulus. Detrusor muscle||Submucosa|. Nephrons are the "functional units" of the kidney; they cleanse the blood and balance the constituents of the circulation.

Trace the pathway that urine would take once it is produced in the renal tubules to when it is released through the process of urination (micturition). Calcitriol – it facilitates bone growth by increasing calcium and phosphorus levels in the blood. 5 litres, excreted as urine. Formation of stone(s) in the ureter. The presence of white blood cells in the urine. The camera's images are transmitted to a computer, where the urologist can determine whether the patient has bladder stones, cancer, or other urinary tract problems (National Institute of Diabetes and Digestive and Kidney Diseases, n. -d). The correct number of major renal calyx is. The bladder muscles relax during filling and contract during urinating. The right kidney is smaller than the left. Renal blood vessels are supplied by both sympathetic and parasympathetic nerves. Tissue with a single layer of irregularly shaped cells that give the appearance of more than one layer (Betts et al., 2013). Peristalsis, intrinsic contraction of smooth muscle, propels urine through the calyces, renal pelvis and ureters to the bladder. Internal urethral sphincter||Ureteral openings|. Hormones that influence selective reabsorption 13.

0, but the pH of normal urine samples can range from 4. The components of nephron is. Antibiotic sensitivity test. Drugs that are structurally small can be filtered by the glomerulus with the filtrate.
