Summary
This document appears to be lab notes for a biology course, focusing on the circulatory system. It covers blood vessels, including blood, heart, circulatory plan, arteries, arterioles, capillary beds, and veins. Topics like blood pressure, blood flow, and vasodilation/vasoconstriction are also included.

# LAB 4 ## Blood Vessels - Blood - Blood vessels - Heart - Circulatory plan of the body - Closed system - Arteries - Large Elastic Arteries - Arterioles - Capillary beds - Venules - Veins - Large Venous Valves ### Blood Vessel Structure #### Vessels - Vasodilation - Vasoconstriction #### Tunics - Tunica externa (adventitia) - Tunica media - External elastic lamina - Elastic fibers - Smooth muscle - Tunica interna - Internal elastic lamina - Arteries & arterioles play major role in regulation of blood pressure ## LAB 4 ### Artery and Vein and Nerve ## LAB 4 - Tunica media: dense regular elastic tissue - Large elastic artery example is aorta ## LAB 4 - Hemodynamics - Blood pressure - Pressure gradient - Blood flow - Peripheral resistance - Blood vessel radius - Blood vessel length - Blood viscosity - Blood volume - Vessel compliance - Measuring blood pressure - Systole - Diastole - Sphygmomanometer and stethoscope ## LAB 4 ### Gross Anatomy of Vascular System #### Pulmonary System - Pulmonary circuit - Right atrium - Right ventricle - Pulmonary arteries - Pulmonary veins - Left atrium - Left ventricle - Systemic circuit - Celiac - Gastric - Gonadal - Hepatic - Mesentery - Renal - Splenic #### General circulatory pathway schematic - Figure 4.1. General circulatory pathway schematic #### Systemic Circulation - Systemic circulation - Pulmonary circulation - Body organs - Ascending aorta - Aorta - Veins - Vena cava - Right atrium - Right ventricle - Pulmonary artery - Lungs - Pulmonary vein - Left atrium - Left ventricle - Aorta - Body organs
