Final answer:
A general infection occurs when bacteria and toxins are transported by the circulatory system throughout the body. Bacterial infections of the circulatory system, if untreated, can lead to conditions like bacteremia, septicemia, and more severe responses such as sepsis and septic shock due to inflammatory immune responses.
Step-by-step explanation:
A general infection occurs when the circulatory system carries bacteria and toxins to various parts of the body. When bacteria enter the circulatory system, this can lead to a condition called bacteremia, which, if not controlled, may escalate into septicemia as bacteria reproduce in the blood. Bacterial infections in the circulatory system can become serious, with high mortality rates if left untreated.
These pathogenic microorganisms often enter the bloodstream via cuts, wounds, or insect bites that break the skin barrier, and from localized infections spreading to more systemic circulation. Furthermore, in the hospital setting, nosocomial infections can occur, resulting in pathogens accessing the bloodstream. The immune response to this bacteremia or toxemia is sometimes more harmful to the body than the infection itself, causing systemic inflammatory response syndrome (SIRS), sepsis, and potentially leading to septic shock, a life-threatening condition.
When considering treatment, the first line of defense often involves antibiotics, but resistant strains may require a more synergistic approach. The quick elimination of these bacteria and microbial toxins is crucial in preventing the severe systemic inflammatory response that can cause significant organ damage
