29 12.5 Essay Questions 1) Explain the origin and pathway of lymph. Answer: Lymph fluid arises from blood plasma that has been forced out of the capillary beds by osmotic and hydrostatic pressures. The fluid left behind is called interstitial fluid. The interstitial fluid is then picked up by lymph capillaries, after which it is called lymph. Lymph is routed up the lymphatic vessels until it is finally returned to the venous system through either the right lymphatic duct or the thoracic duct. Page Ref: Bloom's: 2) Comprehension 2) Describe how the lymphatic and cardiovascular systems are similar in structure and function. Answer: Structurally, lymphatic vessels and the veins of the cardiovascular system are both thin-walled and operate under low-pressure. Some of the larger vessels in each system have valves. Functionally, both systems return fluids back to the heart. The lymphatic system is assisted by the same techniques as the cardiovascular system to return lymph (and venous blood) back to the heart: milking action of skeletal muscles, pressure changes in the thorax during breathing, and smooth muscles in the walls of the vessels. Page Ref: 400 Bloom's: 4) Analysis 3) Explain how the innate and adaptive immune systems differ in their responses to foreign substances. Answer: The innate immune system is the system we have when we're born. This system includes the skin and mucous membranes, the inflammatory response, and proteins already present in our cells. This system is the first one to come into contact with a foreign substance and thus is always prepared to defend the body. Therefore, we think of the innate system as the nonspecific body defense and the first line of defense to protection from invaders. The adaptive immune system is the second line of defense which defends us from specific invaders. This system consists of molecules like pyrogens and immune cells such as lymphocytes and macrophages. This system differs from the innate system since it must be exposed to the invader before it can form a response. Page Ref: 404 Bloom's: 4) Analysis 4) Identify the four most common indicators and major symptoms of an acute inflammatory response and explain their origins. Answer: The four most common indicators of the inflammatory response are redness, heat, swelling, and pain. Redness and heat are a result of dilation of blood vessels that increase blood flow to the injured area. Swelling occurs when increased permeability of the capillaries allows plasma to leak from the bloodstream into the tissue spaces. The excess fluid, or edema, triggers the activation of pain receptors in the area, accounting for the pain associated with an injury. Page Ref: 406 Bloom's: 2) Comprehension 29

30 5) List and describe the cells and chemicals the body uses as its second line of defense. Answer: 1. Phagocytes, such as neutrophils or macrophages, engulf foreign particles. These cells are in nearly every body organ and confront pathogens that make it through the surface membrane barriers. 2. Natural killer cells, found in blood and lymph, are lymphocytes. They can lyse and kill cancer cells and virus-infected body cells. 3. The inflammatory response is a nonspecific response that occurs when body tissues are injured. Page Ref: 406, 407 Bloom's: 2) Comprehension 6) Contrast the primary humoral response with the secondary humoral response. Answer: The primary humoral response occurs during the first encounter with an antigen. An antigen binds to a specific receptor on a specific B cell. The activated B cells proliferate to form a clone. While most of the B cell clone members become plasma cells that will secrete antibody molecules, B cells that do not become plasma cells will become memory cells. Memory cells exist for years and are capable of responding to the same antigen at a later meeting (immunological memory). Secondary humoral responses are the later immune responses that are faster, more prolonged, and more effective than the primary humoral response because preparations for this attack have already been made. Page Ref: Bloom's: 4) Analysis 7) Let's suppose scientists have discovered a new disease that arises when antigen-presenting cells (APCs) are not made by the body. How do you think our immune response will be impacted? ntigen-presenting cells (APCs) engulf an antigen and present part of it on the membrane in combination with one of the APCs' own glycoproteins. T cells require the presentation of the antigen for activation and clonal selection. Without the presentation of antigens by APCs, the immune process would be severely impaired. T cell clone classes provide for cell-mediated immunity and include helper T cells, cytotoxic T cells, regulatory T cells, and memory cells. Page Ref: 414, 421 Bloom's: 3) Application 30
