Macrophage attaches and envelopes antigen into phagosome where it chops it up then lets it go b. i. 1. But one part is kept to surface, where it"s passed to the help t cell via cd4 (protein on surface of helper t cell) to activate t cell b. i. 2. Help t cell can send that message to b cell (memory) or killer t cell (destroyer: short distance - gmail, cell cell (local regulator, neurotransmitter, when neurons are connected, sends messages to spinal cord, brain, etc. b. i. Where two neurons meet, they are not connected so we use a local regulator like a neurotransmitter b. i. 1. Signals flow across synapse (gap: long distance facebook, message goes to everyone, cell (cid:0) cell (hgh human growth hormone, decide if they really want to act on it) b. i.
