BIOS255 Anatomy and Physiology with Lab III – Full Course Papers BIOS255 Anatomy and Physiology with Lab III – Full Course Papers Question Permalink: https://nursingpaperessays.com/ bios255-anatomy-…-course-papers / The Heart (graded) The human heart is a four-chambered hydraulic pump. cThe pressure differences created by the heart move blood between the chambers and the circulatory systems. Let’s begin our discussion by identifying the chambers of the heart and their functions, the associated valves, and the names and general route of their associated great vessels. The Contraction Cycle (graded) The contraction cycle of the heart is the series of events that occurs during one heartbeat. Each beat of the heart includes the contraction (systole) and relaxation (diastole) of the atria and then the ventricles. Let’s begin the examination of this cycle by discussing electrical conduction through the heart. BIOS255 Anatomy and Physiology with Lab III – Full Course Papers week 2 Blood Vessel Structure (graded) Let’s start by discussing the structure of our blood vessels. Let’s each take a characteristic of (1) arteries, (2) veins, or (3) capillaries. Build upon what your classmates say to enable us to have a more full understanding of these vessels that are essential for our existence. Blood Flow Dynamics (graded) Cardiac output is the amount of blood ejected from the left or right ventricle in any given minute. Cardiac output must be maintained in order to keep sufficient blood flow through the capillaries. Identify the factors that directly affect blood flow in the circulatory system. BIOS255 Anatomy and Physiology with Lab III – Full Course Papers week 3 Whole Blood (graded) Describe the composition, physical characteristics, and functions of whole blood. Explain why it is classified as a connective tissue. Liquid Connective Tissue (graded) Explain the similarities and differences among serum, lymph, and plasma. Each student should take one characteristic of the fluid, extracellular component of this connective tissue and explain how it relates to the other liquids. BIOS 255 week4 The Lymphatic System (graded) How do the various components of the lymphatic system operate? We have talked about many organ systems. In what ways are components of the lymphatic system involved in many other organ systems? Try to focus on one element of this system and provide an in-depth view of its contribution to our overall health. Nonspecific Immunity (graded) How do the various elements of the nonspecific immune system function in providing daily protection against a variety of pathogens? Each student should provide a unique aspect of the nonspecific immune system and educate the rest of us concerning its function and how effective (or ineffective) it is against one class of pathogens. BIOS255 Anatomy and Physiology with Lab III – Full Course Papers week 5 B and T Cells (graded) Our knowledge and understanding of the various forms of lymphocytes continue to expand. Our initial discussion this week will be on the various forms of B and T cells — each of us should take one class of lymphocytes and explain it’s role in the adaptive immune process. As you comment on other students’ postings be sure to add additional insight into the mechanisms of the subclass of cell and its interactions with both components of the innate and other aspects of the adaptive immune system. Vaccinations – Friend or Foe (graded) Recently a number of individuals have claimed that adjuvants, such as thymersol in vaccines, lead to the development of a variety of disorders, such as autism. Although these initial claims have not been substantiated and have since been withdrawn from the scientific literature, the concern continues today. How would you counsel parents concerning vaccination? Discuss the issue of herd immunity and the risks in our modern society related to refusal to provide vaccinations. BIOS 255 week 6 Respiratory Anatomy (graded) Describe the anatomy and histology of the respiratory system and how each of the functions are related. Breathing (graded) Describe the events that cause inhalation and exhalation and how Boyle’s law relates to the events. BIOS 255 week 7 Transport of Gases (graded) Describe how oxygen and carbon dioxide are transported in the blood, and explain how their loading and unloading is affected by temperature, pH, BPG, and PCO2. Respiratory Diseases (graded) Compare the causes and consequences of chronic bronchitis, emphysema, asthma, and lung cancer. Once we have made these comparisons then we should follow up on other disorders that affect either the upper or lower respiratory systems. Be sure to comment on others postings in terms of new information that can contribute to a more complete understanding of the diseases you pick. Devry BIOS255N Week 4 Midterm Exam Answers Question 1.
