Infectious Diseases Affecting the Cardiovascular and Lymphatic System

Flashcards covering key vocabulary and concepts from the lecture on infectious diseases and their effects on the cardiovascular and lymphatic systems.

Cardiovascular System

System responsible for circulating red blood cells and oxygen throughout the body.

Lymphatic System

System primarily responsible for circulating white blood cells and other immune components.

Closed Systems

Systems that have no natural portal of entry or exit, requiring substances to cross membranes to enter.

Septicemia

Fungemia

Presence of fungi in the blood.

Septic Shock

Endocarditis

Inflammation of the inner lining of the heart, often associated with pre-existing heart conditions.

HACEK Bacilli

A group of bacteria that are normal respiratory flora, often responsible for causing endocarditis.

Bubonic Plague

Form of plague characterized by swollen lymph nodes, caused by the bacteria Yersinia pestis.

Septicemic Plague

A severe form of plague when Yersinia pestis enters the bloodstream.

Tularemia

Zoonotic infection known as rabbit fever, transmitted through contact with infected rabbits.

Cat Scratch Fever

Infection caused by Bartonella henselae, typically resulting in swollen lymph nodes, often self-limiting.

Lyme Disease

Bacterial infection caused by Borrelia burgdorferi, known for bull's eye rash and chronic symptoms.

Hemorrhagic Fevers

Group of viral infections including Ebola and Dengue, marked by extreme fever and bleeding.

HIV

Human Immunodeficiency Virus, which attacks the immune system, leading to acquired immunodeficiency syndrome (AIDS).

Malaria

Parasitic infection caused by Plasmodium species, characterized by hemolytic anemia.

Gastroenteritis

Inflammation of the gastrointestinal tract, often caused by various pathogens, including Campylobacter jejuni.

Cholera

Infection caused by Vibrio cholera, leading to severe diarrhea and dehydration.
