Abstract:
* The high rate of proliferation required of the bone marrow renders it highly susceptible to the influence of external factors. * Anaemia is the most common haematological abnormality seen in systemic disorders. * In the anaemia of chronic disease, erythropoietin production is reduced and proliferation of erythroid progenitor cells is also impaired; this anaemia can generally be alleviated by correction of the underlying disease process. * The status of the endocrine system must always be considered in evaluation of a normocytic, normochromic anaemia. * Anaemia in infection can be due to host or parasite factors or to the treatment administered. * Anaemia due to malignant disease responds to erythropoietin therapy in many cases; failure to respond is a poor prognostic sign.

Fluid Connective Tissues: Blood and Lymph
Blood
The blood flows through blood vessels— arteries, capillaries, and veins. Blood plasma is primarily made of proteins, solutes, and water.
Overview of the Cardiovascular System
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.
