Answer:
C) Stomach, mucosa of the mouth, and lungs
Explanation:
The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.
Inhalation results in rapid absorption due to its large surface area and abundant blood supply to the alveoli.
Sublingual administration is useful for drugs with high first-pass metabolism, such as nitroglycerin.
This would be an example of absorption through oral mucosa.
