Also maintain tight junctions between endothelial cells, and make capillaries dilate to increase blood flow where neuron activity is high. Active transport-systems protein pump specialized for the transport of particular substance across a membrane. Apoptosis genetically programmed cell death that occurs when a cell is under stress, or to eliminate malfunctioning or sick cells.
