 B)False  True

Question 2

Accepted Answer

A) True 
 B)False  False

Question 3

Explain the processes of reabsorption and secretion.List some substances that are moved by each process.

Accepted Answer

Reabsorption and secretion are two important processes that occur in the kidneys as part of the formation of urine.

Reabsorption is the process by which substances that were filtered out of the blood in the glomerulus are reabsorbed back into the bloodstream. This occurs primarily in the renal tubules. Some substances that are reabsorbed include water, glucose, amino acids, and electrolytes such as sodium, potassium, and chloride.

On the other hand, secretion is the process by which substances are actively transported from the blood into the renal tubules to be excreted in the urine. This process helps to eliminate waste products and regulate the concentration of certain substances in the body. Some substances that are secreted include hydrogen ions, potassium ions, and certain drugs and toxins.

Overall, reabsorption and secretion are crucial processes for maintaining the body's fluid and electrolyte balance, as well as for eliminating waste products.
