About This Quiz


Do you want to test your knowledge of the urinary system? Urine is produced in the kidneys through filtration of blood. The urine is then circulated through the ureters to the bladder, where it is stored. The average amount of urine passed daily is equal to 800-2,000 milliliters, which can vary depending upon how much liquid you drink. If you want to obtain more knowledge about the urinary system, this is the quiz for you.

    Aldosterone stimulates

    • Potassium secretion and sodium reabsorption

    • Calcium reabsorption and phosphate secretion

    • Idk

    Correct Answer
    A. Potassium secretion and sodium reabsorption
    Explanation
    Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in regulating electrolyte balance in the body. It acts on the kidneys to increase the reabsorption of sodium ions and the secretion of potassium ions. This helps to maintain proper levels of sodium and potassium in the blood, which is essential for maintaining normal cellular function. Therefore, the correct answer is that aldosterone stimulates potassium secretion and sodium reabsorption.

    The hypothalamic thirst center is stimulated by increased

    • Bloop pressure

    • Blood water content

    • Blood osmolarity

    Correct Answer
    A. Blood osmolarity
    Explanation
    The hypothalamic thirst center is responsible for regulating thirst and water intake in the body. It is stimulated by changes in blood osmolarity, which refers to the concentration of solutes in the blood. When blood osmolarity increases, indicating a higher concentration of solutes, it signals the hypothalamic thirst center to activate and trigger the sensation of thirst. This helps to maintain the body's fluid balance by prompting the individual to drink more water and restore normal osmolarity levels.

    Angiotensin 2 stimulates

    • Aldosterone release

    • Adh realease

    • Thirst

    • All of the them

    Correct Answer
    A. All of the them
    Explanation
    Angiotensin 2 is a hormone that plays a crucial role in regulating blood pressure and fluid balance in the body. It acts on various organs and tissues to stimulate different responses. Angiotensin 2 stimulates the release of aldosterone, a hormone that promotes sodium and water reabsorption in the kidneys, leading to increased blood volume. It also stimulates the release of ADH (antidiuretic hormone), which promotes water reabsorption in the kidneys, further contributing to fluid retention. Additionally, angiotensin 2 triggers the sensation of thirst, encouraging the individual to drink more fluids. Therefore, all of these responses are stimulated by angiotensin 2.

    A mystery solute can be detectd in tubular fluid, but not in urine. the solute must be

    • Filtered and reabsorbed.

    • Sereted only

    • Filtered only

    Correct Answer
    A. Filtered and reabsorbed.
    Explanation
    The fact that the mystery solute can be detected in tubular fluid but not in urine suggests that it is being filtered by the kidneys but then reabsorbed back into the bloodstream. This indicates that the solute is going through the process of filtration, where substances are removed from the blood and enter the tubular fluid, and then reabsorption, where some of these filtered substances are taken back into the bloodstream. Therefore, the correct answer is that the solute must be filtered and reabsorbed.

    Antidiuretic hormone

    • Increases the permeability of collecting duct's cell membranes to water

    • Increases the volume of urine provide

    • Stimulates sodium reabsorption in the collecting duct

    Correct Answer
    A. Increases the permeability of collecting duct's cell membranes to water
    Explanation
    Antidiuretic hormone (ADH) increases the permeability of collecting duct's cell membranes to water. This means that ADH allows water to move more easily through the cell membranes of the collecting duct, resulting in increased water reabsorption from the urine back into the bloodstream. This action helps to concentrate the urine and reduce water loss from the body. ADH does not increase the volume of urine produced or stimulate sodium reabsorption in the collecting duct.

    Atrial natriuretic peptide opposes the effects of

    • Angiotensis 2

    • Aldosterone

    • Adh

    • All of them

    Correct Answer
    A. All of them
    Explanation
    Atrial natriuretic peptide is a hormone that is released by the atria of the heart in response to increased blood volume and pressure. Its main function is to promote the excretion of sodium and water by the kidneys, thereby reducing blood volume and pressure. This opposes the effects of angiotensin 2, aldosterone, and ADH (antidiuretic hormone), all of which promote water and sodium reabsorption by the kidneys and therefore increase blood volume and pressure. Therefore, atrial natriuretic peptide counteracts the actions of all these hormones.

    The ureters enter the bladder

    • On its superior surface.

    • On its inferior surface.

    • On its later surface.

    • None of these are right; it varies from person to person.

    Correct Answer
    A. On its inferior surface.
    Explanation
    The ureters enter the bladder on its inferior surface. This is the correct answer because anatomically, the ureters, which are tubes that carry urine from the kidneys to the bladder, enter the bladder from below. They connect to the bladder at the trigone, which is located on the inferior surface of the bladder.

    Which of the following is not an extracellular fluid?

    • Interstitial fluid

    • Cytosol

    • Blood plasma

    • Both interstitial fluid and cytosol

    Correct Answer
    A. Cytosol
    Explanation
    Cytosol is not an extracellular fluid because it is the liquid component of the cytoplasm, which is the substance within a cell. Extracellular fluids are found outside of the cells and include interstitial fluid and blood plasma.

    Renin is produced by

    • Granular cells

    • Glomerular cells

    • Endothelial cells

    Correct Answer
    A. Granular cells
    Explanation
    Renin is an enzyme that plays a crucial role in the regulation of blood pressure. It is primarily produced and released by the granular cells, also known as juxtaglomerular cells, located in the walls of the afferent arterioles in the kidneys. These cells respond to various signals, such as low blood pressure or low sodium levels, by secreting renin into the bloodstream. Once released, renin acts on a protein called angiotensinogen, initiating a cascade of reactions that ultimately leads to the production of angiotensin II, a potent vasoconstrictor that helps to raise blood pressure.

    During urination

    • The detrusor muscle contracts.

    • The internal urethral sphincter contracts.

    • The external urethral sphincter contracts.

    • All are right.

    Correct Answer
    A. The detrusor muscle contracts.
    Explanation
    During urination, the detrusor muscle contracts. The detrusor muscle is a smooth muscle located in the wall of the bladder. When it contracts, it helps to squeeze the urine out of the bladder and into the urethra for elimination. The internal urethral sphincter and the external urethral sphincter also play a role in controlling the flow of urine, but they do not contract during urination. Therefore, the correct answer is that the detrusor muscle contracts.

    Which of the following problems would increase the glomerule filtration rate

    • A decreased concentration of blood proteins, resulting from dietary protein deficiency.

    • A blockage in a ureter, which increases the hydrostatic pressure of the filtrate.

    • Reducted bp due to hemorrhage.

    Correct Answer
    A. A decreased concentration of blood proteins, resulting from dietary protein deficiency.
    Explanation
    A decreased concentration of blood proteins resulting from dietary protein deficiency would increase the glomerular filtration rate. Blood proteins, such as albumin, help maintain the osmotic pressure in the blood vessels. When the concentration of blood proteins decreases, the osmotic pressure decreases as well. This reduction in osmotic pressure causes less water to be reabsorbed in the proximal tubules and more water to remain in the filtrate. As a result, the glomerular filtration rate increases because more fluid is being filtered by the glomerulus.

    Salts

    • Have a positive charge

    • Are acidic

    • Are uncharged

    • Are basic

    Correct Answer
    A. Are uncharged
    Explanation
    Salts are uncharged because they are formed by the reaction between an acid and a base, resulting in the transfer of an electron from the metal in the base to the non-metal in the acid. This transfer creates ions with opposite charges, which then combine to form a neutral compound known as a salt. Therefore, salts do not have a positive or negative charge, making them uncharged.

    Glucose is reabsorbed in the proximal tubule by

    • Primary active transport

    • Secondary active transport

    • Osmosis

    Correct Answer
    A. Secondary active transport
    Explanation
    Glucose is reabsorbed in the proximal tubule by secondary active transport. This means that the reabsorption of glucose requires the use of energy, which is provided by the movement of another molecule or ion down its concentration gradient. In this case, glucose is co-transported with sodium ions, utilizing the energy generated by the movement of sodium ions into the cell. This process allows glucose to be efficiently reabsorbed from the filtrate back into the bloodstream.

    The medullary osmotic gradient exists between

    • Successive layers of the renal medulla

    • The glomerulus and the glomerular capsule

    • The proximal tubule and the distal tubule

    Correct Answer
    A. Successive layers of the renal medulla
    Explanation
    The medullary osmotic gradient exists between successive layers of the renal medulla. This gradient is important for the concentration and dilution of urine. The renal medulla is divided into several layers, each with a different osmolarity. This gradient allows for the reabsorption of water and solutes in the descending limb of the loop of Henle, as well as the secretion of solutes in the ascending limb. This process helps to maintain the osmolarity of the body fluids and regulate water balance.

    The presence of acidic urine indicates that

    • The kidney is generateing new bicarbonate molecules

    • The body is in a state of alkalosis

    • Blood bicarbinate concetrations are high

    • All of these are right

    Correct Answer
    A. The kidney is generateing new bicarbonate molecules
    Explanation
    The presence of acidic urine indicates that the kidney is generating new bicarbonate molecules. Bicarbonate is a base that helps to neutralize acids in the body. When the body is in a state of acidosis, the kidneys work to produce more bicarbonate to restore the pH balance. Therefore, the presence of acidic urine suggests that the kidneys are actively producing bicarbonate to counteract the excess acid in the body.
