Compare innate and acquired immunity‚ and how they differ in terms of how quickly they attack a pathogen‚ and how they recognize a pathogen. Innate immunity- immediate defense upon infection and foundation for adaptive immunity -rapid response -distinguishes non-self from self- molecular recognition. then‚ receptor molecules bind specifically to molecules from foreign cells

Innate immunity Pathogens are constantly trying to invade the human body. These pathogens are been fought against in the body using a defense mechanism known as immunity (ref). Innate immunity is the body’s first line defense mechanism against infection or foreign pathogens that attempts to enter the body(ref). This type of immunity is present at birth‚ its non-specific at its action and has no previous memory of foreign pathogens it attacked (ref). Innate immunity provides the body

Physical : Skin (epidermis + dermis) and mucous membranes 2. Internal: Cell and chemicals that inactivate or kill invaders Adaptive immunity (p.446): The body’s ability to recognize and defend itself against distinct invaders and their products. 2) Five attributes of adaptive immunity (p.471) 1.

Welcome to the Fantastic Voyage! Now that we have successfully been shrunk and injected into the patient’s femoral vein‚ let me explain what our journey will entail. The first destination will be the lower lobe of the right lung. The patient’s immune system has been fighting an evil invasion of bacterium in the lung‚ and it is our assignment to document the battle. Once we have witnessed the patient’s immune system in action‚ we will head across the alveolar membrane and onward out the nose. Let
