Column 1, #1 Pulmonary circuit. What is the name of the circuit that pumps blood out to the lungs and back to the heart? Column 1, #2 left ventricle. Which chamber pumps blood out to the body systems? Column 1, #3 Right atrium Which chamber receives deoxygenated blood from the body? Column 1, #4 Left atrium. Which chamber receives oxygenated blood from the pulmonary circuit? Column 1, #5 Atrioventricular (AV) valves. What is the name of the structures that ensure one-way blood flow from the atria to the ventricles. Column 2, #1 Endocardium. What is the term for the inner lining of the pumping chambers of the heart? Column 2, #2 Superior and inferior venae cavae. What is the name of the large veins that carry the systemic blood back to the right atrium? Column 2, #3 Chordae tendinae. What is the name of the structures that anchor the cusps of the AV valves? Column 2, #4 Visceral pericardium. Which layer of the epicardium covers the heart surface? Column 2, #5 Contractile cells. Which type of cardiac cells provide the pumping action and make up 99% of all cardiac muscle cells? Column 3, #1 Conducting cells (non-contractile cells). Which type of cardiac cells generate and spread the action potential? Column 3, #2 QRS complex. On an EKG, which component represents ventricular depolarization? Column 3, #3 T wave. On an EKG, which component represents ventricular repolarization? Column 3, #4 Cardiac AP has a long plateau phase. Cardiac muscle has a long, slow twitch. Cardiac muscle has a long refractory period, which prevents tetanus. What are some of the differences between cardiac and skeletal muscle cells? Column 3, #5 systole. What is another name for the contraction phase of the cardiac cycle? Column 4, #1 Diastole. What is another name for the relaxation phase of the cardiac cycle? Column 4, #2 “lubb” Identify the first heart sound caused by the closing of the AV valve. Column 4, #3 Lowers heart rate and stroke volume. What effect does parasympathetic innervation have on heart rate and stroke volume? Column 4, #4 Raises heart rate and stroke volume. What effect does sympathetic innervation have on heart rate and stroke volume? Column 4, #5 The hardening and thickening of the walls of smaller arteries. What is arteriosclerosis? Column 5, #1 The formation of plaques in the inner wall of blood vessels. What is atherosclerosis? Column 5, #2 Arrhythmia. What is another term for a disturbance in the rhythm of the cardiac cycle? Column 5, #3 Coronary heart disease. Which condition results from arteriosclerosis and atherosclerois? Column 5, #4 Brachycardia. Which term describes a slowing in the heart rate (below 60 bpm)? Column 5, #5 Bonus Question 1: Describe the series of events that allows the ear to detect sound. Bonus Question 2: (a) Describe the series of events that allows you see an image. (b) What is the name of the structure in the brain that perceives the image and flips it right-side up.
