Describe the vessels that blood passes through

Starting and ending at the heart, describe the vessels that blood passes through. Include detailed descriptions and comparisons of arteries, capillaries, and veins — histology, anatomy, and specific functions, and relating structure to function. Which type of blood vessel is the main contributor to blood pressure? What local structure(s) help regulate blood flow through capillary beds? 2. Define blood pressure and describe and compare specific types (eg. arterial, MABP, venous, PP). Include their expected values or ranges.

Explain what happens to pressure when blood flows further away from the heart. During the rest period before starting an exercise routine where is most of the blood concentrated? Upon initiating exercise what happens to blood flow and pressure? 3. Define cardiac output and explain the various factors that affect both it and blood pressure. Be as specific as you can. 4.

Define total peripheral resistance/systemic vascular resistance and explain the three main factors influence both it and blood flow. How are velocity and cross-sectional area related with regard to blood flow? Describe bulk flow and net filtration pressure. With regards to blood flow, what two structural mechanisms aid in venous return? 5. Review the various blood vessels from the appendices in your third lab on circulation as you will be identifying many of these vessels in the tutorial. 6. Describe the following circulatory pathways, including the functions of key structures: Fetal circulation, Cerebral Arterial Circle, and the Hepatic portal system. Please note: it is advisable to compare the fetal pathway with the adult, identifying key differences and similarities.
