What is meant by micturition?
- A.
The act of passing urine
- B.
The act of passing faeces
- C.
The act of filtration within the glomerular capsule
- D.
The act of re-absorption of proteins, amino acids and sugars in the nephrons of the kidneys
Correct Answer
A. The act of passing urineExplanation
Micturition refers to the act of passing urine. It is the process by which urine is expelled from the body through the urethra. This occurs when the bladder muscles contract and the sphincter muscles relax, allowing urine to flow out of the body. Micturition is a normal physiological process that helps eliminate waste products and maintain the balance of fluids in the body.Rate this question:

Which disease/disorder results in calcium deposits forming in the renal pelvis?
- A.
Kidney stones
- B.
Gall bladder stones
- C.
Nephritis
- D.
Glomemlonephritis
Correct Answer
A. Kidney stonesExplanation
Kidney stones are formed when calcium deposits accumulate in the renal pelvis, causing a disease/disorder known as nephrolithiasis. This condition occurs when there is an imbalance in the levels of certain minerals and salts in the urine, leading to the formation of hard deposits in the kidneys. These deposits can vary in size and can cause severe pain and discomfort when they pass through the urinary tract. Treatment options for kidney stones include medication, lifestyle changes, and in some cases, surgical intervention.Rate this question:

What is the function of antidiuretic hormone?
- A.
Stimulates basic metabolic rate
- B.
Increases water reabsorption in kidneys
- C.
Maintains calcium levels in bones
- D.
Contracts the uterus during labour
Correct Answer
B. Increases water reabsorption in kidneysExplanation
The function of antidiuretic hormone is to increase water reabsorption in the kidneys. This hormone is released by the pituitary gland in response to low blood volume or high blood osmolality. It acts on the kidneys to increase the reabsorption of water, which helps to conserve water in the body and prevent excessive water loss through urine. This helps to maintain the body's fluid balance and prevent dehydration.Rate this question:

- D.
The act of re-absorption of proteins, amino acids and sugars in the nephrons of the kidneys _______
Correct Answer
A. The act of passing urineExplanation
Micturition refers to the act of passing urine. This process involves the relaxation of the urinary sphincter muscles, allowing urine to flow from the bladder through the urethra and out of the body. Micturition is controlled by the nervous system, specifically the coordination between the bladder muscles and the muscles of the urethra. It is a natural and necessary bodily function to eliminate waste products and maintain fluid balance in the body.Rate this question:

What is the name given to inflammation of the kidney?
- A.
Cystitis
- B.
Nephritis
- C.
Glomerulonephritis
- D.
Kidney stones
Correct Answer
B. NephritisExplanation
Nephritis is the correct answer because it refers to inflammation of the kidney. Cystitis is the inflammation of the bladder, not the kidney. Glomerulonephritis specifically refers to inflammation of the glomeruli in the kidney. Kidney stones are not related to inflammation but rather the formation of solid deposits within the kidneys.Rate this question:

Where does the pigment that gives urine its colour come from?
- A.
The liver
- B.
The pancreas
- C.
Urea
- D.
Bile
Correct Answer
D. BileExplanation
Bile is the correct answer because it is a yellowish-green fluid produced by the liver and stored in the gallbladder. It is released into the small intestine to aid in the digestion and absorption of fats. Bile contains a pigment called bilirubin, which gives urine its yellow color when it is excreted from the body. The liver processes bilirubin and excretes it into the bile, which eventually ends up in the urine.Rate this question:

The function of the renal pelvis is to:
- A.
Take urine from the bladder to the outside
- B.
Collect urine from the medulla and pass it to the ureter
- C.
Act as a reservoir
- D.
Take urine from the kidney to the bladder
Correct Answer
B. Collect urine from the medulla and pass it to the ureterExplanation
The renal pelvis is a funnel-shaped structure in the kidney that collects urine from the medulla, which is the innermost part of the kidney, and then passes it to the ureter. The ureter then carries the urine from the kidney to the bladder. Therefore, the correct answer is "Collect urine from the medulla and pass it to the ureter."Rate this question:

Define brights disease:
- A.
Inflammation of the urethra
- B.
Inflammation of the kidney
- C.
Inflammation of the ureter
- D.
Inflammation of the bladder
Correct Answer
B. Inflammation of the kidneyExplanation
Bright's disease, also known as nephritis, is a medical condition characterized by inflammation of the kidney. It can be caused by various factors such as infections, autoimmune disorders, or certain medications. The inflammation can affect the kidney's ability to filter waste products and excess fluid from the blood, leading to symptoms such as swelling, high blood pressure, and changes in urine output. If left untreated, Bright's disease can result in kidney damage and potentially lead to kidney failure. Therefore, it is important to diagnose and manage the inflammation promptly to prevent further complications.Rate this question:

During filtration and urine production, reabsorption takes place in the:
- A.
Convoluted tubules
- B.
Calyces
- C.
Bowmans capsule
- D.
Urethra
Correct Answer
A. Convoluted tubulesExplanation
During filtration and urine production, reabsorption takes place in the convoluted tubules. This is because the convoluted tubules are responsible for reabsorbing important substances such as water, glucose, amino acids, and electrolytes from the filtrate back into the bloodstream. This reabsorption process helps to maintain the body's water and electrolyte balance and prevent the loss of valuable substances. The other options, such as the calyces, Bowman's capsule, and urethra, do not play a significant role in reabsorption during urine production.Rate this question:

The percentage of urea in urine is:
- A.
2%
- B.
4%
- C.
6%
- D.
96%
Correct Answer
A. 2%Explanation
The percentage of urea in urine is 2% because urea is a waste product that is excreted by the kidneys. It is a byproduct of protein metabolism and is filtered out of the blood by the kidneys. The kidneys then excrete urea in the urine. The concentration of urea in urine is relatively low compared to other substances, making up only about 2% of the total urine composition.Rate this question:
