Kidney Function | MCQs

Explanation

• The kidney is responsible for filtering blood.
• Two kidneys that filter your blood, removing wastes and extra water to make urine.
  
• This urine is then passed through the ureters and stored in the urinary bladder.
• The urine is then expelled from the body through the urethra.
  

Explanation

The kidneys are part of the urinary tract that makes urine (pee).

Urine has salts, toxins, and water that need to be filtered out of the blood.

After the kidneys make urine, it leaves the body using the rest of the urinary tract as a pathway.

Explanation

1. Filter blood: Kidneys filter waste products and excess fluid from the blood. 
2. Excrete waste: Kidneys excrete waste products, like urea and uric acid, into the urine. 

Explanation

Each kidney contains around 1 million nephrons.

They are the functional units responsible for filtering blood and producing urine.

Explanation

• Selective reabsorption primarily occurs in the proximal convoluted tubule (PCT).
• To a lesser extent, in the distal convoluted tubule (DCT), where essential nutrients, water, and ions are reabsorbed back into the bloodstream.

Explanation

• The artificial kidney machine is called Hemodialysis.
• It filters waste products and excess fluids from the blood when the kidneys are unable to perform this function adequately.
