Module 04 Case Study: Cardiovascular and Immune/Lymphatic Systems Each question is worth 1 point‚ unless otherwise noted. I’ve Fallen Over and I Can’t Get Up: Part I—"Children Playing in The Heat" Questions 1. What signs and symptoms did Greg exhibit when he was in the house? Some signs and symptoms Greg experienced were thirst‚ dizziness‚ and turgor. 2. Was Mrs. Myron correct when she said that Greg was dehydrated? Which signs and symptoms are consistent with this notion? Mrs. Myron thought

that have gone through the external defense. 5. What is the role of the lymphatic system? The lymphatic system collects fluid that is lost by the blood and returns it back to the circulatory system. 6. How does the lymphatic system aid in immunity? It stores defensive phagocytic cells that defend against substances that enter the lymph nodes. 7. Outline the significant steps that occur during an inflammatory response? The significant steps in the inflammatory response are the release

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.

Mammalian defence against infectious disease can be non-specific‚ otherwise known as innate‚ or specific (adaptive). Non-specific defence can be further categorised into external (preventive) or internal (defensive). Innate defence can be physical‚ chemical or biological. The skin‚ commensal organisms (e.g. bacteria)‚ mucous membranes and hair contribute to the physical mechanism of the body’s non-specific defence against disease. These prevent disease from entering the mammal’s body by acting
