Salts
-
Have a positive charge
-
Are acidic
-
Are uncharged
-
Are basic
Correct Answer
A. Are unchargedExplanation
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.Rate this question:

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.Rate this question:

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.Rate this question:

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.Rate this question:

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.Rate this question:

Glucose is reabsorbed in the proximal tubule by
-
Primary active transport
-
Secondary active transport
-
Osmosis
Correct Answer
A. Secondary active transportExplanation
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.Rate this question:

Aldosterone stimulates
-
Potassium secretion and sodium reabsorption
-
Calcium reabsorption and phosphate secretion
-
Idk
Correct Answer
A. Potassium secretion and sodium reabsorptionExplanation
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.Rate this question:

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 medullaExplanation
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.Rate this question:

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 waterExplanation
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.Rate this question:

The hypothalamic thirst center is stimulated by increased
-
Bloop pressure
-
Blood water content
-
Blood osmolarity
Correct Answer
A. Blood osmolarityExplanation
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.Rate this question:

Renin is produced by
-
Granular cells
-
Glomerular cells
-
Endothelial cells
Correct Answer
A. Granular cellsExplanation
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.Rate this question:

Angiotensin 2 stimulates
-
Aldosterone release
-
Adh realease
-
Thirst
-
All of the them
Correct Answer
A. All of the themExplanation
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.Rate this question:

Atrial natriuretic peptide opposes the effects of
-
Angiotensis 2
-
Aldosterone
-
Adh
-
All of them
Correct Answer
A. All of themExplanation
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.Rate this question:

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 moleculesExplanation
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.Rate this question:
