- D.
None of these
Correct Answer
A. The plasmaExplanation
The kidney works on the plasma. The plasma is the liquid component of blood that carries various substances such as nutrients, hormones, and waste products. The kidney filters the plasma to remove waste products and excess water, while also reabsorbing important substances back into the bloodstream. This process helps maintain the balance of fluids and electrolytes in the body, as well as regulate blood pressure and pH levels. Therefore, the kidney's primary function is to work on the plasma to ensure proper functioning of the body.Rate this question:

Protein is filtered during first process
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
This statement is false. Protein is not filtered during the first process. The first process of filtration in the body is called glomerular filtration, which occurs in the kidneys. During this process, small molecules like water, ions, and waste products are filtered out of the blood and into the renal tubules to form urine. However, proteins are too large to be filtered through the glomerulus and are therefore retained in the blood.Rate this question:

Which one of the following statements is true
- A.
Capillary membrane is more permeable than the cell membrane
- B.
Capillary membrane separates the blood from the intracellular fluid
- C.
Albumin can always pass capillary membrane
- D.
Capillary membrane is less permeable than cell membrane
Correct Answer
A. Capillary membrane is more permeable than the cell membraneExplanation
The correct answer is "Capillary membrane is more permeable than the cell membrane." This is because capillaries are tiny blood vessels with thin walls that allow for the exchange of substances between the blood and surrounding tissues. The capillary membrane is highly permeable, allowing for the movement of various molecules and ions. In contrast, the cell membrane is selectively permeable, meaning it regulates the passage of substances in and out of the cell. Therefore, the capillary membrane is more permeable than the cell membrane.Rate this question:

Insulin increase due to glucose increase
- A.
Negative feedback
- B.
Positive feedback
- C.
All of the above
- D.
None of the above
Correct Answer
A. Negative feedbackExplanation
Insulin is a hormone that helps regulate blood sugar levels. When glucose levels increase in the blood, the pancreas releases insulin to signal cells to take in glucose and lower its concentration. This process is an example of negative feedback, where the increase in glucose triggers the release of insulin to counteract and decrease glucose levels. Positive feedback would involve a process where the increase in glucose would further stimulate the release of insulin, which is not the case here. Therefore, the correct answer is negative feedback.Rate this question:

What juxtagomular cells release?
- A.
Renine
- B.
Angiotensin
- C.
Aldosterin
- D.
Insulin
Correct Answer
A. RenineExplanation
Juxtaglomerular cells release renin. Renin is an enzyme that plays a crucial role in the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and fluid balance in the body. When juxtaglomerular cells detect low blood pressure or low sodium levels, they release renin into the bloodstream. Renin then acts on angiotensinogen, a protein produced by the liver, to convert it into angiotensin I. This sets off a cascade of reactions that ultimately lead to the production of angiotensin II, a hormone that constricts blood vessels and stimulates the release of aldosterone, a hormone that promotes sodium reabsorption in the kidneys.Rate this question:

What is the process protein free plasma move from glomerulus bowman's capsule?
- A.
Filtration
- B.
Reabsorption
- C.
Secretion
- D.
Absorbion
Correct Answer
A. FiltrationExplanation
The correct answer is Filtration. In the process of protein-free plasma movement from the glomerulus to Bowman's capsule, filtration occurs. Filtration is the first step in urine formation, where blood is filtered through the glomerulus, allowing small molecules such as water, ions, and waste products to pass into the Bowman's capsule while retaining larger molecules like proteins. This process is driven by the pressure gradient between the blood in the glomerulus and the fluid in the Bowman's capsule.Rate this question:

Filtration depend on?
- A.
Size
- B.
Charge
- C.
B and A
- D.
Type
Correct Answer
C. B and AExplanation
Filtration can depend on both size and charge. Size is an important factor in filtration as it determines the ability of particles or substances to pass through a filter. Larger particles may be unable to pass through small pores, resulting in their removal during filtration. Additionally, charge plays a role in filtration as particles with a certain charge may be attracted or repelled by the filter, influencing their ability to pass through. Therefore, both size and charge are factors that can affect the filtration process.Rate this question:

The relationship between rate of diffusion and molecular weight?
- A.
Direct proportion
- B.
Inverse proportion
- C.
Non of the bove
- D.
All of the above
Correct Answer
B. Inverse proportionExplanation
The relationship between the rate of diffusion and molecular weight is inversely proportional. This means that as the molecular weight increases, the rate of diffusion decreases, and vice versa. This can be explained by the fact that larger molecules have more mass and therefore move more slowly, resulting in a slower rate of diffusion. Conversely, smaller molecules have less mass and move more quickly, leading to a faster rate of diffusion.Rate this question:

Substance enter the renal tubule in two way? a-Filtration
- A.
Filtration and reabsorption
- B.
Filtration and secretion
- C.
Secretion and absorption
- D.
None of the above
Correct Answer
A. Filtration and reabsorptionExplanation
The correct answer is "Filtration and reabsorption." In the renal tubule, substances enter through the process of filtration, where small molecules and ions are filtered out of the blood and into the tubule. Reabsorption then occurs, where useful substances such as water, glucose, and ions are reabsorbed back into the blood from the tubule. This process helps regulate the body's water and electrolyte balance. Secretion and absorption are not the only ways substances enter the renal tubule, and none of the above options are correct.Rate this question:

- B.
Thrombin
- C.
Fibrinogin
- D.
A & C
Correct Answer
D. A & CExplanation
The inactive form of the clotting factors includes Prothrombin and Fibrinogen. Prothrombin is a protein that is converted into the active enzyme thrombin during the blood clotting process. Thrombin then converts fibrinogen into fibrin, which forms the meshwork of a blood clot. Therefore, both Prothrombin and Fibrinogen are inactive forms of clotting factors that play crucial roles in the clotting cascade.Rate this question:
