Question

The "clean-up" cells are located in the ________ layer of alveolar membrane.
A)Surfactant
B)Epithelial
C)Interstitial space
D)Capillary endothelium

Accepted Answer

The "clean-up" cells in the alveolar membrane refer to the macrophages located in the epithelial layer of the membrane. These cells are responsible for clearing away any debris or pathogens that may have entered the lungs. Surfactant is a substance produced by cells in the alveoli to prevent the collapse of the air sacs, the interstitial space refers to the space between cells in the membrane, and the capillary endothelium refers to the thin layer of cells that line the capillaries.
