The main function of your kidneys is to make urine from waste products and excess water found in your blood?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The main function of the kidneys is to filter waste products and excess water from the blood, which are then excreted as urine.

One quarter of your blood passes through your kidneys every hour?
- A.
True
- B.
False
Correct Answer

Minute filtration units in your kidneys are known as?
- A.
Nephrons
- B.
Renin
- C.
Dialysis
- D.
Valves
Correct Answer
A. NepHronsExplanation
Nephrons are minute filtration units in the kidneys. They are responsible for filtering waste products and excess water from the blood, producing urine. Each kidney contains millions of nephrons, which consist of a glomerulus and a tubule. The glomerulus filters blood, while the tubule reabsorbs necessary substances and excretes waste products. Nephrons play a crucial role in maintaining the body's fluid balance and regulating blood pressure.Rate this question:

When your kidneys detect that your blood pressure is dropping, they secrete an enzyme called?
- A.
Nephrons
- B.
Renin
- C.
Dialysis
- D.
Oxymaralis
Correct Answer
B. ReninExplanation
When your blood pressure drops, your kidneys secrete an enzyme called renin. Renin plays a crucial role in the renin-angiotensin-aldosterone system, which helps regulate blood pressure. Renin acts on a protein called angiotensinogen, converting it into angiotensin I. This is then converted into angiotensin II, a potent vasoconstrictor that helps raise blood pressure. Ultimately, this process helps to restore blood pressure to normal levels. Therefore, the correct answer is Renin.Rate this question:

What procedure works by using a machine that replicates the blood cleansing function of healthy kidneys?
- A.
Oxymaralism
- B.
Dialysis
- C.
Cortex Replication
- D.
Chemotherapy
Correct Answer
B. DialysisExplanation
Dialysis is a procedure that replicates the blood cleansing function of healthy kidneys. It involves using a machine to filter waste products, excess fluids, and toxins from the blood when the kidneys are unable to perform this function properly. This helps to maintain the balance of electrolytes and fluids in the body. Oxymaralism, cortex replication, and chemotherapy are unrelated to the blood cleansing function of healthy kidneys.Rate this question:

When the kidneys absorb more salt and water, it leads to a decrease in blood pressure?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
When the kidneys absorb more salt and water, it actually leads to an increase in blood pressure, not a decrease. This is because the increased salt and water retention causes an increase in the volume of blood circulating in the body, leading to higher blood pressure.Rate this question:

Nephrons filter out all of the following substances from your blood except?
- A.
Nitrogen compounds
- B.
Salts
- C.
Acids
- D.
Sulfates
Correct Answer
D. SulfatesExplanation
Nephrons are tiny structures in the kidneys that play a crucial role in filtering waste and excess substances from the blood to form urine. Nitrogen compounds, salts, and acids are all substances that can be filtered out by the nephrons. However, sulfates are not typically filtered out by the nephrons. Therefore, the correct answer is sulfates.Rate this question:

What system are the kidneys a part of?
- A.
Urinary
- B.
Reproductive
- C.

People need two proper functioning kidneys to live a normal healthy life?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
People can live a normal healthy life with just one properly functioning kidney. The remaining kidney can compensate for the loss of the other kidney and perform its functions adequately. In some cases, individuals may even be born with only one kidney and still live a normal life without any health complications. Therefore, it is not necessary for people to have two properly functioning kidneys to live a normal healthy life.Rate this question:
