Study Notes

Blood Composition

Cellular elements occupy approximately 45% of a person's blood.

Blood Circulation Function

The primary function of blood circulation within the cardiovascular system is to transport oxygen and nutrients to tissues and remove waste products.

Blood Plasma Composition

Blood plasma is approximately 7% protein by weight.
Water makes up approximately 92% of the weight of plasma.

Plasma Concentrations

The normal plasma concentrations of selected ions and small molecules are almost the same as those in the interstitial fluid because the plasma and interstitial fluid are in equilibrium.

Chapter Overview

The chapter "The Composition of Blood" mainly discusses the composition of blood, including the percentage of cellular elements, blood plasma composition, and other components.
