Many different microbes can cause sepsis. Although bacteria are most commonly the cause, viruses and fungi can also cause sepsis. Infections in the lungs (pneumonia), bladder and kidneys (urinary tract infections), skin (cellulitis), abdomen (such as appendicitis), and other organs (such as meningitis) can spread and lead to sepsis. Infections that develop after surgery can also lead to sepsis.

Circulatory System
Circulatory System, or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Among its vital functions, the circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature.
