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.
NOTES
and the left side serving the systemic circuit. In Figure 16-15, complete
the schematic showing the blood flow to and from the heart (the starting
points are given to you). Use a blue pen or pencil to denote the direction of
deoxygenated blood and a red pen or pencil for oxygenated blood flow.
Include the names of the major vessels, chambers, and valves involved,
based on the following list:
lung capillary beds
body capillary beds
right ventricle
left ventricle
bicuspid valve
superior vena cava
tricuspid valve
inferior vena cava
pulmonary semilunar valve
pulmonary trunk
aortic semilunar valve
R. and L. pulmonary arteries
R. and L. pulmonary veins
aorta

Identify if the statements are TRUE or FALSE.
TRUE

STATEMENT
The sinoatrial node is situated in the wall of the interventricular septum.
Left ventricle ->Left atrium ->Right ventricle ->Right atrium is the correct sequence for blood entering the heart through the vena cavae and leaving through the aorta.
The outermost of the three layers of the heart is supracardium.
A stenosis of the bicuspid valve might cause blood to back up into the venae cavae.
The valve that is located on the same side of the heart as the pulmonary semilunar valve is the mitral valve.
Angina pectoris is the comprehensive term for heart attack.
Cutting the vagus nerves where they innervate the heart would increase the heart rate.
During the ventricular contraction all the blood is forced out of the ventricles.
At late diastole, the atria and ventricles are relaxed and the aortic…

- Please list in order the chambers and valves blood passes through on its way through the heart. Identify whether blood has high or low oxygen content as it passes through each structure.Start with the vessel returning blood to the heart from the systemic circulation: ____________________ (superior structures) or _____________________ (inferior structures)↓____________________↓____________________↓____________________↓____________________↓Pulmonary trunk↓Left and right pulmonary arteries↓Lungs↓Vessels returning oxygenated blood to the heart = ______________________ ↓____________________↓____________________↓____________________↓Aorta (systemic circulation)arrow_forwardPlease explain blood flow through your body in a flow diagram format (do not put a picture of heart or write a paragraph). Start and end at the inferior/superior vena cava.

TRUE FALSE STATEMENTS When the atrioventricular bundle is completely interrupted, the ventricles typically contract at 30 to 40 beats/minute. The left ventricular wall of the heart is thicker than the right wall in order to pump blood with a greater pressure.
