Document Summary
Lecture 1: the cell & its constituents: the body"s fluid compartments and their major ions. 1. 1 the body contains mainly water1: makes up ~ 60% of body mass & is constant % of lean body mass. 1. 2 body h20 is distributed across four compartments. Extracellular component of blood, i. e. , fluid in blood outside blood cells fluid in blood outside blood cells. Separated from plasma by single plasma by single layer of epithelial layer of epithelial cells, with h2o-filled cells, with h2o-filled pores pores. Water is distributed (unevenly) across four distinct compartments or spaces in the body. These are: intracellular fluids (64% of all body water): this is the fluid found within cells. Just by virtue of it has an important passive role as the site for metabolic processes including production. However it also has a very important active (in the sense of actively participating in the role) of acting as a buffer to constant maintain the extracellular environment.
