Answer to Question 1

When deprived of sufficient essential nutrients, indispensable tissues and cells of the immune system can dwindle in size and number, leaving the whole body vulnerable to infection. The skin and body linings, the first line of defense against infections, become thinner because their connective tissue is broken down, allowing agents of disease easy access to body tissues. A healthy digestive system normally musters a formidable defenseits linings not only impose a physical barrier but also are heavily laced with immune tissues, cells, and antibodies that intercept intruders. When malnutrition sets in, all of these defenses diminish, and invading infectious agents encounter little resistance. Once inside the warm, moist, nutritious body fluids and tissues, microbes quickly multiply and infection ensues.
