Question

Many anatomical structures rely on an amplified surface area to perform their function. Match the examples of the amplified surface area with their correct function

a. Nerve cells, called neurons, are cells with highly branched structures, which increase the surface area of the cells. ___
b. The inner surface of the small intestine contains folds and fingerlike projections, called villi. The cells that line the vill are covered with smaller projections called microvilli. These structures dramatically increase the surface area. ___
c. The antennae of a moth contains many short, thin hairlike projections that increase surface area. ___
d. The air passages in mammalian lungs end in saclike regions called alveoli. Alveoli look like clusters of grapes. compartments of the alveoll increase the surface area ___
- Absorption of nutrients
- increased intercellular communication
- Sense chemicals in the air
- increased oxygen absorption

Answer 1

Nerve cells have highly branched structures to aid in intercellular communication. The inner surface of the small intestine contains folds and projections, increasing its surface area for nutrient absorption. Moth antennae and mammalian lungs also have structures that amplify their surface area.

Step-by-step explanation:

To match the amplified surface area with their correct function:

1. Nerve cells: Nerve cells, called neurons, have highly branched structures that increase the surface area of the cells. This increased surface area aids in intercellular communication.
2. Small intestine: The inner surface of the small intestine contains folds and fingerlike projections called villi. The cells that line the villi are covered with smaller projections called microvilli. These structures dramatically increase the surface area, aiding in the absorption of nutrients from digested food.
3. Moth antennae: The antennae of a moth contain many short, thin hairlike projections that increase the surface area. This increased surface area allows the moth to sense chemicals in the air.
4. Mammalian lungs: The air passages in mammalian lungs end in saclike regions called alveoli. The clusters of grape-like compartments in the alveoli increase the surface area, facilitating increased oxygen absorption.
