Blood’s function in cell communication: From hormone signaling to Oxygen transport

Abstract

A wide array of factors facilitates vital communication between cells in the body. The characterization, regulation, functions, and mechanisms of these factors have been the subject of extensive research in this field. Most of the detailed descriptions of cell-tocell communication molecules that have been identified over the years include proteins, small peptides, amino acids or their derivatives, ions, lipid metabolites, and steroids. In addition, hormones participate in many vital functions in the body, most importantly growth, development, metabolism, mood, and immune responses. These essential processes depend on the hormone’s ability to reach its target tissue. Hormones travel through the bloodstream, passing through the vascular endothelium and performing various biological processes within the body.
