Explanation:

The interstitial fluid and blood plasma together make the extracellular fluid. The extracellular fluids are present outside the cells. The extracellular fluid that is present in the narrow spaces between cells of tissues is known as interstitial fluid. When a substance moves from blood plasma into the cells of a tissue, it crosses the interstitial fluid present between its cells. Therefore, when a skeletal muscle cell picks glucose molecules from blood plasma, it moves from plasma to the interstitial fluid to enter the cell.

Antibodies are produced when the body is exposed to
erica [24]


Antibodies are produced when the body is exposed to antigens.

During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.

On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.

The antibodies effectively neutralize the antigen and facilitate its destruction.

The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
