Draw a coronal cross-section of a heart, labeling all chambers, valves, and blood vessels that contribute to the functioning of the heart. Draw arrows denoting blood flow throughout the heart. Briefly describe how the heart beats (and the electrical conductance system that controls heart beats)

Trace the journey of a drop of blood starting from the right atrium, continuing to the right thumb, and returning to the right atrium.  This would include a trip through the heart. Be sure to identify both the arterial and venous vessels as well as all of the relevant structures within the heart. Considering the online nature of this exam, drawings are not required. Simply type in the order of structures with a dash (-) between structures.

Number the structures involved in depolarization of heart from the one which depolarizes first (1) to the one which depolarizes last. A-V node Purkinje fibers right and left bundle branches atria

Assume a person has had a widowmaker heart attack. Sketch out (i.e. draw) a diagram of the heart and coronary blood vessels and please explain detailed what is happening during this event.

Trace the flow of blood through from the inferior vena cava all the way to the aorta. Be sure to include all the structures.

In a paragraph or using an arrows, trace the blood flow from the superior vena cava, inferior vena cava and coronary sinus entering the heart to the pulmonary circulation and systemic circulation.

You are an erythrocyte in the vena cava. Starting there, trace your route through the heart and back into the systemic circulation by naming, in order, all of the major valves, chambers, and organs you will pass through.

Outermost layer of the heart as organ itself     Composed of skeletal muscle     Composed mainly of cardiac muscle tissue     Also referred to as the epicardium     Area filled with serous fluid to decrease friction     Functions to bring air in and out of lungs     Outermost portion of sac composed of dense irregular connective tissue     Innermost layer of the heart organ     Middle layer of the heart organ     Most superficial layer secreting serous fluid     Entire protective structure surrounding heart     Identify location of entrance and exit of blood vessels     Tapered end of heart pointing toward left hip     Most deep layer secreting serous fluid     fills and empties of blood

Choose all the correct statements. The right atrium receives deoxygenated blood from the body cells. Blood in the left ventricle is oxygenated and is sent out through the aorta to all the cells of the body. Blood in the left ventricle is pumped into the pulmonary artery. The superior and inferior vena cava deliver deoxygenated blood to the right atrium. The heart has 2 ventricles and 3 atria. The mitral valve is the tricuspid valve. The surface of the heart is covered by the visceral pericardium. The left side of the heart pumps blood to the lungs.

Fill in the blank:  Normally, the _______________________ node serves as the pacemaker of the heart.
