Questions: Do you think that absorptive cells have additional structures that enhance the absorption in the small intestine? Make your assumption, and let's find out together! a) Yes, they have additional structures aiding the absorption b) No, the small intestine is complex enough to ensure maximum absorption

The answer is the first one (a): Yes, they have additional structures aiding the absorption.

Explanation for each option:

a) Yes, they have additional structures aiding the absorption: This is correct. The absorptive cells in the small intestine, known as enterocytes, have additional structures called microvilli. These microvilli form a brush border on the surface of the enterocytes, significantly increasing the surface area for absorption. This enhanced surface area allows for more efficient absorption of nutrients.

b) No, the small intestine is complex enough to ensure maximum absorption: This is incorrect. While the small intestine is indeed complex, the presence of additional structures like microvilli is crucial for maximizing absorption. Without these structures, the efficiency of nutrient absorption would be significantly reduced.

In summary, absorptive cells in the small intestine have additional structures, such as microvilli, that enhance the absorption of nutrients.
