5. Explain why there is a difference in oxygen content of the blood on the two sides of the heart.
According to uofmhealth.org..I found that the right side of your heart “receives oxygen-poor
blood from your veins and pumps it to your lungs”, and it picks up oxygen and gets rid of CO2.
The left side of your heart “receives oxygen-rich blood from your lungs and pumps it through
your arteries” to the rest of your body.
PART 2
1. In your own words, define pulmonary circuit and systemic circuit.
The pulmonary circuit in the heart allows the blood to take up oxygen in the lungs while in the
systemic circuit the oxygenated blood is distributed to the tissues in the body.
2. Based on where they must pump blood to, which side of the heart do you think must pump
harder, right or left? Explain your answer, and use anatomical evidence from the heart to
support your argument.
The left ventricle has to be the strongest pump because it has to pump blood to the entire body.
The left ventricle also must supply most of the hearts pumping power so that it can pump the
same amount of blood even if there is heart failure to keep the blood circulating. The left
ventricle also has a thicker walls than the right because it needs to pump blood to most of the
body while the right ventricle primarily pumps/fills the lungs.
3. Based on what you’ve learned so far, which side of the heart do you think more commonly
weakens faster and fails first? Explain your answer.
Although the walls are thicker on the left side of the heart it is most likely the first to get weaker
due to the abundant amount of work that it must produce overtime. Usually left-sided heart
failure can cause our trigger the right side heart failure but if the left side chamber of your heart
loses some of its ability to pump blood it can cause a Trumatic injury to the body. The blood
work back up into your lungs if the left ventricle does not pump efficiently and therefore it would
cause shortness of breath.
PART 3
1. If the left side of the heart fails, where in the circulation would blood back up? What about the
right side?
If the left side of your heart fails the circulation would cause the blood to back up in the
pulmonary circulation which would produce congestion in the lungs. Right side heart failure and
see if it was left si
