Chapter 16 Urinary System Quizlet
A student of classical physics says, "A charged particle, like an electron orbiting in a simple atom, shouldn't have only certain stable energies; in fact, it should lose energy by electromagnetic radiation until the atom collapses. " C. Bowman's capsule. Urinalysis (urine analysis) often provides clues to renal disease. The middle layer of the urinary bladder is identified as ___________. Even then, serial sections and computer reconstruction are necessary to give us a comprehensive view of the functional anatomy of the nephron and its associated blood vessels. Because glomeruli filter the blood based mostly on particle size, large elements like blood cells, platelets, antibodies, and albumen are excluded. Chapter 15 the urinary system answer key. I give the students either a printed copy of the fill in the blank notes or share a digital version through Google Classroom.

Chapter 15 The Urinary System Packet Answer Key
Female Pelvis Model. The remainder of the nephron and the collecting duct are formed by a single layer of simple squamous epithelium (Fig. Ammonia is extremely toxic, so most of it is very rapidly converted into urea in the liver. Urinary System Practice Exam. The bladder muscles relax during filling and contract during urinating. It is characterized by blood or protein in the urine and edema. Use the models and posters to observe the following features of the blood vessels of the kidney and urinary system. Dehydration may produce darker, more concentrated urine that may also possess the slight odor of ammonia. This takes place through the semipermeable walls of the glomerulus (Fig. The renal medulla is composed of tissue called ______.
Hydrostatic (fluid) pressure is sufficient to push water through the membrane despite the osmotic pressure working against it. Interlobar Blood Vessels||Renal Nerve|. Surrounding the glomerulus is a thin, double-walled capsule, known as the glomerular capsule (Bowman's capsule) and the space between each is known as the capsular space. A. prostatic urethra. Substances not required and foreign materials, e. Chapter 15 urinary system answer key west. drugs including penicillin and aspirin, may not be entirely filtered out of the blood because of the short time it remains in the glomerulus. The closed or blind end is indented to form the cup-shaped glomerular capsule (Bowman's capsule), which almost completely encloses a network of tiny arterial capillaries, the glomerulus. The renal columns also serve to divide the kidney into 6 to 8 lobes and provide a supportive framework for vessels that enter and exit the cortex. The caffeine in coffee and tea works by promoting vasodilation in the nephron, which increases GFR.
Blood, bilirubin, protein, ketones, pH, glucose, and nitrites), but also their relative amounts. It is within the peritubular capillaries that reabsorption and secretion will take place. Ethacrynic Acid (EDECRIN). In the male, pseudostratified columnar epithelium lines the urethra between these two cell types. During late pregnancy, its capacity is reduced due to compression by the enlarging uterus, resulting in increased frequency of urination. The composition of urine reflects exchange of substances between the nephron and the blood in the renal capillaries. Chapter 15: Urinary System Sonography II Workbook Flashcards. Recognize the medical specialties associated with the urinary system. Urine from here flows into the major calyces – the larger openings. The renal structures that conduct the essential work of the kidney cannot be seen by the naked eye. The urinary system consists of two kidneys, two ureters, a single urinary bladder, and a single urethra (Figure 25. Proteins are broken down into amino acids, which in turn are deaminated by having their nitrogen groups removed. Under normal conditions, urine will also contain only trace amounts of glucose (≤ 30 mg per 100 mL of urine). What are some abnormalities you observed in each of the other 4 "patient" samples? Examination of the inside of the kidney and ureter, using a ureteroscope.
Chapter 15 The Urinary System Answer Key
In females, the urethra is ~1. Also called urination or voiding. 2 names 4 the double-layered cup that surrounds the glomerulus in a nephron. • Check what students have learned from the chapter by having them complete the Study Guide. A healthy adult passes from 1000 to 1500 mL per day. The male urethra (Figure 25.
The color of urine is determined mostly by the breakdown products of red blood cell destruction. The blood that exits from the glomerulus passes through a membrane (three-layered) initiating the process of filtration. Since the external urinary sphincter is voluntary skeletal muscle, actions by cholinergic neurons maintain contraction (and thereby continence) during filling of the bladder. At the other end of the spectrum, production of consistently alkaline urine is a sign of metabolic or respiratory alkalosis or a urinary tract infection. Chapter 15 the urinary system packet answer key. After passing through the renal corpuscle, the capillaries form a second arteriole, the efferent arteriole (see Figure 15. Overall, the principle task of the nephron population is to balance the plasma to homeostatic set points and excrete potential toxins in the urine. The interior of the bladder comprises three layers –. Numerous small glands in the prostate produce a liquid which gets mixed with the sperm in the urethra at the time of orgasm. ADH, released by the posterior pituitary, works to do the exact opposite. Medical Terms in Context. Labium majora||Urethra|.
A condition marked by drowsiness and an unusual lack of energy and mental alertness. These structures pour the urine into the minor calyces – the cup-shaped receptacles. Dialysis is a treatment that removes waste products from the blood when the kidneys are not fully functioning. Blood volume is important in maintaining sufficient blood pressure, and there are nonrenal mechanisms involved in its preservation, including vasoconstriction, which can act within seconds of a drop in pressure. Animated text boxes are utilized to release information at the teacher's pace. Incision into the bladder. Microscope lens cleaning solution. This excess protein in the filtrate leads to a deficiency of circulating plasma proteins. This can be used to help students prepare for a chapter test. The primary function of the descending loop of Henle in the kidney is?
Chapter 15 Urinary System Answer Key West
The urinary system is functional in turning toxic substances into the urine, storing and carrying urine, and safely eliminating it from the body. Urine leaves the body through the _________ (urethra/ureter). In some regions of the cortex, the efferent arterioles may also branch to give rise to the vasa recta. Genetic and Rare Diseases Information Center. Nephrons are the "functional units" of the kidney; they cleanse the blood and balance the constituents of the circulation. Using the marker or wax pencil, label each tube with the name or number of each artificial urine sample.
As the afferent arterioles enter into the nephron, they will form a tuft of high-pressure capillaries known as the glomerulus. Outer portion of the kidney that appears granular. National Library of Medicine. Urine will always have a specific gravity greater than pure water (water = 1. The exact type of bacterial growth is determined by conducting a urine culture.
The main functions of the kidneys are: Urine is stored in the bladder and excreted by the process of micturition. In cases of high blood pressure, diuretics may be prescribed to reduce blood volume and, thereby, reduce blood pressure. The collecting ducts are continuous with each nephron, but not technically part of it. A region of the forebrain below the thalamus; has function in both the autonomic and endocrine systems and regulates homeostasis. Most of the ammonia produced from protein breakdown is converted into urea by the liver, so ammonia is rarely detected in fresh urine. Preserved pig or sheep kidney dissection specimen. These food-caused odors are harmless though. Urine is formed through the purification of plasma by glomerular filtration, tubular absorption, and secretion. There is also an opposing force, the osmotic pressure, which is typically higher in the glomerular capillary. Inflammation of the lining of the bladder. Efferent Arterioles||Renal Artery|. The hilum is the concave medial border of the kidney where the renal blood and lymph vessels, the ureter and nerves enter.
Note the use of the term "reabsorbed. "
