requires life, biologic activity, and the cell's expenditure of metabolic energy.
Unlike passive transport, active transport occurs across only living membranes
that have to drive the flow "uphill" by coupling it to an energy source (p. 28)
The uptake and use of nutrients and other substances from the cells surrounds (pg.
3).
"Histamine is the major vasoactive amine released from mast cells. It causes dilation
of capillaries and retraction of endothelial cells lining the capillaries, which increase
vascular permeability" (Pg. 217)
, Antiviral drugs do not cure HIV because the infected cells act as a reservoir. The
main infected cell is the CD4+ memory T cells, other infected cells include
macrophages, dendrites, microglia, astrocytes, and hematopoietic progenitors.
Theses infected cells continue to release viral particles if therapy is stopped. (Pg

Definition
A reduction in ATP levels causes the plasma membrane's sodium-
potassium pump (Na+-K+) and sodium-calcium exchange to fail, which
leads to an intracellular accumulation of sodium and calcium, resulting
in cellular swelling and diffusion of potassium out of the cell (p. 51)
Cellular swelling, the most common degenerative change, is caused by
the shift of extracellular water into the cell. In hypoxic injury, movement
of fluid and ions into the cell is associated with acute failure of
metabolism and loss of ATP production. Normally, the pump that
transports sodium ions (Na+) out of the cell is maintained by the
presence of ATP in adenosinetriphosphatase (ATPase), the active
transport enzyme. In metabolic failure caused by hypoxia, reduced
