Question

Imagine you are a red blood cell sitting in the right atria of the heart. In your laboratory journal, write a paragraph that describes what happens to this red blood cell as it moves through the body. What structures will it pass through?

How will it interact with oxygen? Think back to Unit 3 and make sure to include the word hemoglobin in your response.

Answer 1

Right atrium -----> Atria contracts and passes through the tricuspid valve -------> Now in right ventricle ------> Ventricles eventually contract and now blood goes past pulmonary valve into the pulmonary trunk into pulmonic circulation where gas exchange occurs in the alveoli and CO2 is exhaled & released from the carboxyhemoglobin portion of hemoglobin and O2 inspired and binds to one of the alpha/beta chains of hemoglobin ---------> Blood now returns via pulmonary veins and ends up in the left atrium ----------> atria contract and blood passes the mitral valve ----------> blood now in the left ventricle -----------> left ventricle eventually contracts and blood passes through the aortic semilunar valve into the aorta to go out into systemic circulation.
