5.2 Physiology of the Lymphatic System and Immunology Flashcards
What does an immune response involve?
identifying foreign particles and eliminating them
What are the two types of immune responses?
nonspecific
specific
What is the nonspecific immune response known as?
innate immune system
What is the innate immune response?
first line of defense through physical and chemical barriers to prevent pathogens from entering the body
Which immune response acts quickly?
nonspecific
How long does it take to activate the specific immune response?
several days
What is the specific immune response also known as?
adaptive immune system
What is the specific immune response?
targeted response against specific pathogens
What are the main lymphocytes involved in the specific immune response?
T cells
B cells
What is the integumentary system?
skin
What immune response is the skin a part of?
nonspecific
What are normal flora?
good bacteria
What do normal flora produce?
lactic acid which inhibits pathogenic bacteria
How does the stomach help the nonspecific immune response?
stomach acid and digestive secretions helps destroy microorganisms
How does the respiratory system help the nonspecific immune response?
mucus will trap pathogens
What immune response are fevers and the inflammatory response a part of?
nonspecific
What is the inflammatory response?
localized response in the tissue where increased blood flow goes to the infected region causing swelling
What is tissue swelling?
when blood vessels in the affected area dilates increasing the number of immune cells responding to the infection
What helps bring a conscious awareness to an infection?
redness and pain caused by the increase in blood flow to the affected area
What are cytokines?
secreted proteins that help regulate and signal both specific and nonspecific immune systems
