2. Blood travels next through this valve and into this chamber After the left ventricle blood travels through this valve, into this vessel and is on its way to this organ Returning from the lungs, blood travels through this vessel, into this chamber From the left atrium blood goes through this valve and into this chamber Finally blood exits the left ventricle through this valve into this vessel These are the tendinous cords that anchor the valves to the walls of the ventricles These vessels nourish the heart This branch of the nervous system, along with the intrinsic conduction system, regulates the heart beat Name the two major nodes and their location Name the three branches from the AV node

3. Describe the contractions of the atria and ventricles with relation to right and left halves as well Contraction and relaxation of the ventricles Describe mid-to-late diastole Describe ventricular systole Describe early diastole Amount of blood pumped by each side of the heart in one minute Volume of blood pumped by each ventricle in one contraction CO = SV x ____________ Name three things which can increase heart rate Name two things which can decrease heart rate Describe the arrangement of vessels beginning with those leaving the heart and ending with those coming to the heart, based on diameter List the three tunics of the vessels

4. This tunic of the artery is very thick and composed of this tissue type Name the unique structure veins contain that arteries do not What assists in venous blood return against the force of gravity The flow of blood through a capillary bed is called what What is the direct link from arteriole to venule All of the vessels that make up a capillary are collectively called what What structure sacrifices blood flow through the true capillaries Define Blood Pressure Friction exerted between flowing blood and the endothelial tissue
