WGU Pathophysiology Study Guide: D236 Pathophysiology Lesson 1 TO Lesson 11 WGU Pathophysiology Study Guide: D236 Pathophysiology Lesson 1 TO Lesson 11: Pathophysiology Remediation Lesson 1: Homeostasis Concepts 1. Starling's Law of Capillary forces is the force behind the movements of fluid in capillary beds throughout the body. The two forces at work are hydrostatic and osmotic pressures. Homeostasis is achieved when these two forces are equal in the capillary- cell interfaces. When...

NUR 521 IMMUNITY ALL ANSWERS CORRECT first line: innate/physical, mechanical second line: inflammation third: adaptive (acquired) specific what's the difference between the first, second & third immunity? increased capillary permeability what causes the edema that occurs during the inflammatory process? physical immunity physically bars pathogens from entering the body -skin sloughing off with dead cells, GI, GU and respiratory lining, mucus and cilia trap microorganisms -expe...

8-1 Which of the following contributes to the activation of naive T cells? a. neutrophils b. B cells c. macrophages d. dendritic cells e. basophils correct answersd 8-6 Macrophages exhibit all of the following characteristics except _____. a. they trap and degrade pathogens in secondary lymphoid organs b. they deliver co-stimulatory signals to naive T cells needed for T-cell priming c. they migrate from sites of infection to nearby secondary lymphoid organs e. they remove and degrade...

biome, parturition, and preterm birth As we begin to understand changes in the microbiome that occur during pregnancy, a natural question to ponder is the role of the microbiome in the regulation of the timing of parturition and notably preterm birth. While the dogma currently states that preterm birth is initiated by an ascending infection from the vaginal cavity to the placenta, recent studies have challenged this idea (Gonçalves et al., 2002; Madianos et al., 2013). In fact, the coloniz...

PCB 3233 EXAM 2 PRACTICE QUESTIONS AND ANSWERS Induced innate immune response - Answer️️ --Inflammation -Leukocytes called into the site of infection -Soluble molecules made and secreted into the blood and brought to the site of the infection Leukocytes in the order to action - Answer️️ -1. Neutrophils - Mass quantities 2. Monocytes 3.Lymphocytes - days later 2 cell type recognition - Answer️️ -1. NK - looking at your own cells 2. Macrophages - looking at pathogen directly...

Which of the following does NOT protect body surfaces: A Skin B Mucus C Gastric acid D Salivary amylase E Gut microflora - correct answer D - Salivary amylase does not protect body surfaces, as enzymes assist in digestion only. All others influence environment. Pattern recognition receptors (PRR) include: A LPS. B PAMPs. C Lipoteichoic acid. D Lectin-like molecules. E Unmethylated CpG sequences. - correct answer ...

Immunogens and Antigens - correct answer Immunogen: A molecule that can elicit the production of an antibody when introduced into the host. Antigen: A molecule that is recognized and bound by an antibody. An immunogen must be an antigen, but an antigen is not necessarily an immunogen. Innate vs. Adaptive Immune System - correct answer 1) Adaptive takes time to react to pathogen; innate are always present and ready to be mobilized. ...
