Anatomy and Physiology 2402 Lab Exercise 32 Blood Vessels The primary goal of this lab is to learn the names of many blood vessels. You will use the models provided as well as pictures in your lab book. Microscopic Structure of Blood Vessels Tunica intima: lines the lumen of the blood vessel. Continuous with endocardium of heart. Is extremely smooth to decrease resistance to blood flow. (Made of epithelium) Tunica media: More bulky middle coat. Composed of smooth muscle and elastin. Regulation

ESPECIALLY THICK IN ELASTIC ARTERIES‚ CONTAINS SMOOTH MUSCLE AND ELASTIN 4 CHARACTERISTICS OF TUNICA EXTERNA MOST SUPERFICIAL TUNIC‚ HAS A SMOOTH SURFACE TO DECREASE RESISTANCE TO BLOOD FLOW 5 WHY ARE VALVES PRESENT IN VEINS BUT NOT IN ARTERIES? Veins need valves to create pressure to pump the blood to the heart. Blood flows away from the heart and‚ therefore‚ the pressure is not required. Helps against gravity. 6 NAME TWO EVENTS OCCURING WITHIN THE BODY THAT AID IN VENOUS RETURN. 1. Respiratory

Jamison Blood vessels carry blood throughout the entire body. The names of some blood vessels are related to the region which they supply or drain. Most named veins will have the same name of its accompanying artery. Review the blood vessels of the various regions of the body listed below.

Premium Heart
heart is an organ that acts as a ‘’pump’’ because it pumps blood continuously that is rich in a high concentration of oxygen throughout the organs of the human body such as the brain. Blood is carried through tube like structures called blood vessels such as the artery and the vein. The arteries carry blood from the heart at high pressure which contains a high concentration of oxygen and nutrients to supply the organs. Veins carry blood at low pressure to the heart which contains a high concentration

Include in your explanation the major concepts you learned and any safety concerns associated with the lab. Purpose is to understand how the veins and arteries run through the body and how they function while the heart beats‚ where they deliver and drain blood to/from and how the cardiovascular system works together.

BLOOD 1. The important components of blood include plasma‚ erythrocytes‚ and leukocytes. Red blood cells or erythrocytes account for 45 % of the blood. Leukocytes or white blood cells‚ aid in protecting the body from disease as well as platelets. Platelets function to inhibit excessive bleeding from the body. The plasma layer is another layer that constitutes the majority of blood. 2. The Plasma is straw coloured. It has 90% water‚ 7%proteins and 3% other substances. The Plasma protects the
