BIO 291 Lecture Notes - Lecture 2: Nasal Hair, Mucosa-Associated Lymphoid Tissue, Tears
Document Summary
Introduction: name five general non-specific defense mechanisms that act quickly to fight a wide variety of invaders. These mechanisms act quickly to fight a wide variety of. Name five physical barriers that prevent invasion by microbes. The five physical barriers that helps to prevent the invasion by. Microbes include the skin, eye structures, digestive mucosa, Respiratory mucosa, and genitourinary mucosa: name five chemical barriers that prevent invasion by microbes. The five chemical barriers that helps to prevent the invasion by. Microbes include perspiration, keratin, tears, lysozyme, and gastric juice: click on the eye to investigate defense mechanisms found there. Tearing, or lacrimation, is a type of protective barrier mechanism. That washes away he microbes that attempts to enter the eyes. Consists of salts, mucus, and lysozyme that neutralize substances. And bacteria, and washes away the bacteria: click on the respiratory mucosa to investigate defense mechanisms found there, describe the defensive role of nasal hair.
