Villi
The plasma membrane.
The cell most responsible for maintaining homeostasis in the body is the epithelial cell. Epithelial cells form tight barriers between different compartments of the body, regulate the movement of substances in and out of cells, and help maintain the balance of ions and nutrients. Their functions contribute to overall cellular homeostasis.
The basement membrane is what epithelial cells lie on top of. They separations of apposing layers. They have functions, to have compartmentalization They basically have influences in cell proliferation, adheasion, migration, differentiation. Reservoir for growth factors, enzymes and plasma proteins.
The cell membrane is also called the plasma membrane.
Microvilli are plasma membrane extensions that create the most surface area for the cell. These finger-like projections are found in cells involved in absorption, such as the cells lining the small intestine, and increase the cell's ability to transport nutrients.

Glucose molecules cross the plasma membrane on the apical side of epithelial cells through facilitated diffusion using glucose transporters such as GLUT1 and GLUT2. These transporter proteins help the glucose molecules move down their concentration gradient into the cell.
The plasma membrane.
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.

IgA antibodies in human saliva are primarily produced by plasma cells located in the mucosal tissues of the salivary glands. These plasma cells secrete dimeric IgA, which is then transported across the epithelial cells of the salivary glands through a process involving the polymeric immunoglobulin receptor (pIgR). After binding to pIgR, the IgA is secreted into saliva as secretory IgA (sIgA), which plays a crucial role in mucosal immunity by neutralizing pathogens and preventing their adherence to mucosal surfaces.
