BIOS255 Week 3 Cardiovascular System Blood Vessels, Lab

BIOS255 Week 3 Cardiovascular System Blood Vessels, Lab. Learning objectives: 1. Identify the structural layers of arteries and veins. 2. Distinguish between the structure of arteries and veins. 3. Explain 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 AZ>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 1. Purpose: Please state the purpose of the lab. • The purpose of the lab is to get a better understanding on vessels in the BIOS255 Week 3 Cardiovascular System Blood Vessels cardiovascular system. BIOS255 Week 3 Cardiovascular System Blood Vessels 2. Procedure: Briefly discuss the procedure for this lab. • The procedure for this lab is to go through each section under the names cardiovascular system, blood vessels, blood flow and pressure, circulatory pathways, vessels of the trunk, vessels of the head and neck and lastly vessels of the limbs section. Within each section a small quiz will be given to help you better understand each topic. 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 Large artery is known as the aorta which is connected to the heart's left ventricle. Carry blood away from the heart. Medium arteries Can be identified as a muscular artery. draws blood from an elastic artery and branches into "resistance vessels" including small arteries and arterioles. Arterioles A small branch of an artery leading into capillaries. Distribute blood to capillary beds, the sites of exchange with the body tissues.
