Answer:
The function of pulmonary ventilation is to b. maintain adequate alveolar ventilation.
Explanation:
<em>Pulmonary ventilation refers to the movement of air into and out of the lungs, so its main function is to maintain adequate alveolar ventilation.</em> The air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere. In the lungs, Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. That's how the oxygen gets into the bloodstream.

Answer:
C.Mature secretory vesicles
Explanation:
Hello!
Insulin is synthesized in pancreatic ß-cells. It is a small protein formed by two amino acid chains (A-chain, 21aa, and B-chain, 30aa) connected by two disulfuric chains.
The gene encoding is located in the short arm of chromosome 11. Its precursor, called preproinsulin, is synthesized in the endoplasmic reticulum. Right after its synthesis, this protein undergoes enzymatic cleavage to proinsulin (86 aa).
The prohormone is packed in small granules within the Golgi complex, that migrates to the cell surface. As the granules mature, 3 proteases split the proinsulin into equal amounts of insulin and C-peptide.
These secretory granules are stored within the intracellular space until their contents are released by exocytosis.
I hope you have a SUPER day!
