The circulatory system has evolved over time from simple diffusion through cells in the early evolution of animals to a complex network of blood vessels that reach all parts of the human body. This extensive network supplies the cells, tissues, and organs with oxygen and nutrients, and removes carbon dioxide and waste.

It notes that fish have less efficient systems due to pressure loss in gills, while squids use separate pumps. Amphibians possess three-chambered hearts with some blood mixing, whereas lizards have a muscular septum to enhance separation.

The stomach of birds has two chambers: the proventriculus, where gastric juices are produced to digest the food before it enters the stomach, and the gizzard, where the food is stored, soaked, and mechanically ground.

When these systems are infected with a microorganism, the network of vessels can facilitate the rapid dissemination of the microorganism to other regions of the body, sometimes with serious results. In this section, we examine some of the key anatomical features of the circulatory and lymphatic systems, as well as general signs and symptoms of infection.
