PARACRINE
When the ligand is exocytosed in the ECF and is received by the same cell it came from is called
a) paracine
b) autocrine
c) endocrine
d) both a & b
b
T/F: Endocrine sytem uses hormones secreted to the lymphatic system to reach the target organs
F
T/F: Endocrine system also uses ligand via lympgatic systme
F
Important in immune responses
