Identify or trace the path of a red blood cell through all anatomical/structural areas of the heart.
• The red blood cell carrying oxygen is pushed into the aorta through the aortic valve by contraction of the left ventricle (Marieb, Mitchell, Smith, 2013, pg. 446).
• From the aorta, the red blood cell travels into one of the arteries from the arterioles then will hit the capillaries (Marieb, Mitchell, Smith, 2013, pg. 446).
• Within the capillary, the oxygen molecule that is taken by the red blood cell detaches and then passes through the capillary into the body tissues (Marieb, Mitchell, Smith, 2013, pg. 446).
• The deoxygenated red blood cell will then travel through the venules, veins. Then it will return to the right atrium of the heart. It will either use the superior venacava or the inferior venacava (Marieb, Mitchell, Smith, 2013, pg. 446).
• Next the non-oxygenated red blood cell will travel to the right ventricle from the tricuspid valve (Marieb, Mitchell, Smith, 2013, pg. 446).
• As it leaves the right ventricle, the red blood cell comes to the lungs through the pulmonary artery (Marieb, Mitchell, Smith, 2013, pg. 446).
• The lungs will release carbon dioxide by the red blood cell in exchanged for oxygen. Then the red blood cells will become oxygenated (Marieb, Mitchell, Smith, 2013, pg. 446).
• The oxygenated blood travels from the lungs to the left atrium of the heart known as the pulmonary vein (Marieb, Mitchell, Smith, 2013, pg. 446).
• When leaving the left…
