Immune System 1
Skin and mucous are examples of this type of immune system defense.
What is the innate defense?
Any toxin or microorganism that can cause disease
What is a pathogen?
Examples of lymphoid organs responsible for activating lymphocytes
What are secondary- lymph nodes and spleen?
Layers of dead skin near or at the surface of the integumentary system
What is the epidermis?
Synthesize vitamin D, regulate temp, body fluids, and detecting touch
What are other functions of the integumentary system?
Anything that causes an immune system response and is attached to the pathogen.
What is an antigen?
Neutrophils and Macrophages
What are examples of phagocytes?
What are the sites of making and maturing lymphocytes (WBC's)?
Dendritic cells found in this layer
what is one way that you can keep your immune system healthy
Balanced eating plan, 8+ hours of sleep, Stress management
5 serving of fruits and vegetables
Hygiene and hand washing
The second line of innate defense that sounds a chemical alarm as an immune response
