BIOS 255 Week 3 Cardiovascular System Blood Vessels – Lab Assignment (Already GRADED A)

Document Content and Description Below

BIOS255 Week 3 Cardiovascular System: Blood Vessels Learning objectives: 1. Identify the structural layers of arteries and veins. 2. Distinguish between the structure of arteries and veins. 3. Exp ... lain the factors that affect arterial blood flow and blood pressure. 4. Define shock, and identify the signs of shock. 5. Identify key blood vessels of the cardiac, systemic, and pulmonary circulations. Introduction: Blood is transported around the body in 3 different types of blood vessels: arteries, capillaries, and veins. Each blood vessel is composed of 3 layers of tissue. Blood pressure and flow depend on multiple factors. There are a number of mechanisms by which shock can occur. We will track blood through the pulmonary and systemic circulations noting the major arteries and veins in our path. Assignment: Part 1 Complete the activities in the following sections of Anatomy.TV Cardiovascular system: Blood vessels, Blood flow and Pressure, Circulatory Pathways, Vessels of the Trunk, Vessels of the Head and Neck, Vessels of the Limbs To access Anatomy.TV: Resources tab>Library>Library Resources-Database A- Z>Anatomy.TV>Titles(default tab): Choose assigned system>choose assigned sections You will then work through the material and activities by scrolling down on the right. This will allow you to see and work through all activities for that section. Part 2 Complete the lab report. Blood vessel Lab report #%Purpose: Please state the purpose of the lab. -Relate the design of the heart to its function. -Explain the cardiac conduction cycle and its regulation.This study source was downloaded by 100000801755870 from CourseHero.com on 04-15-2022 13:47:48 GMT -05:00 https://www.coursehero.com/file/68069139/BIOS255-Week-3-Cardiovascular-System-Blood-Vessels-1docx/ -Explain the factors that influence the exchange of material between the blood within capillaries and the interstitial fluid surrounding body tissues. 2. Procedure: Briefly discuss the procedure for this lab. -Distinguish between the structure of arteries and veins. -Identify factors that influence cardiac output, blood flow, and blood pressure. -Identify essential blood vessels of the cardiac, systemic, and pulmonary circulations. -Identify the structures of the heart. 3. Data and Details: a. Describe the different types of blood vessels by completing the following chart: Blood vessel Description/special characteristics Function Large arteries Elastic arteries, also referred to as conducting arteries, are large and conduct blood from the heart to muscular arteries. They have well defined internal and external elastic laminae, and their tunica media is thick and full of elastic fibers (elastic lamellae), enabling their walls to stretch easily with an increase in blood pressure (high compliance), as seen during systole. They propel blood from the heart during ventricular diastole. Their elastic properties are essential to accommodate the volume of blood created when blood is expelled from the heart. As they stretch, elastic fibers store mechanical energy, which isThis study source was downloaded by 100000801755870 from CourseHero.com on 04-15-2022 13:47:48 GMT -05:00 https://www.coursehero.com/file/68069139/BIOS255-Week-3-Cardiovascular-System-Blood-Vessels-1docx/ [Show More]
