Lecturer Dr Samah A Jassam BSc MSc PhD MRSB AlMustansiriya University Collage of Pharmacy Two major types of stem cells in mammals 1 Embryonic stem cells that are isolated from the inner cell mass of . Lori Herrington. Chaparral High School. What is immunology?. Very simply, it is the study of our body’s defense against infection and disease.. Even though we are constantly bombarded by microorganisms, we rarely become sick. Why?. THE IMMUNE SYSTEM. NONSPECIFIC DEFENSES AGAINST INFECTION INCLUDE THE. SKIN. MUCOUS MEMBRANES. PHAGOCYTIC CELLS. ANTIMICROBIAL PROTEINS. THE IMMUNE SYSTEM. NONSPECIFIC DEFENSE MEANS THAT THEY DON’T DISTINGUISH BETWEEN MICROBES. What is the Immune System?. Our body’s natural defensive line to foreign material called microbes.. Without an immune system, microbes would quickly attack our bodies.. Our body has three levels of defense against foreign invaders. . Oral immunity and . immunopathological. processes in the mouth.  Immunity. Microorganisms are in the air we breathe and in/on the food we eat;. Thus our epithelial surfaces are continuously exposed to microorganisms;. Chapter 31 Sections 1-4, 6. Pathogens and Human Illness. What are some causes of diseases?. We can have infectious and noninfectious diseases.. Infectious can be passed from one person to another because of germs. What are some examples?. Chapter 4. Introduction. Molecules recognized as “non-self” are antigens. Several mechanisms to protect itself . First level of protection include physical and biochemical-skin, acid in stomach. Second level of protection phagocytic cells, enzymes, and proteins. A stem cell is . a . “blank” cell. It can divide and produce identical . . copies – Self Renewal . P. rocess. Serves as a built-in repair system for . . . human . body. What Stem Cell does?. is. 1- . a . non-specialized. , . 2- generic . cell which can make exact copies of. itself . indefinitely and. 3- . can differentiate and produce specialized cells for the . various tissues . of the . Immunity. Immunity. The ability of the body to fight infection and/or foreign invaders by producing . antibodies or killing infected cells.. Immune System.

Immune System recognizes the identity of foreign substances. Antigens are found on the cells of all organisms and your body is able to identify your own cells and tell when a foreign cell has entered the system. The Immune System. The immune system is a group of cells & soluble molecules, which interact & distinguish patterns in the body as “self” or “non-self,” in order to eliminate those that are “non-self.”. Immunology. Study of the components and function of the immune system. Immune System . Molecules, cells, tissues and organs which provide non-specific and specific protection against. Microorganisms. What is the Immune System?. The immune system is a vast network of cells and tissues.. Located throughout your body.. Involves numerous types of cells, organs, proteins, and tissues.. The immune system can distinguish between your tissues and foreign tissue/ invaders.. Los Angeles ORT College\'s STEM Education Program stands out among STEM schools in California. The college provides a dynamic learning environment that encourages creativity, critical thinking, and problem-solving skills, ensuring that graduates are well-equipped for success.
