Focusing on the cardiovascular system, Stan starts a new lecture series on organs. No, not the state in the Pacific Northwest and definitely not the large piped musical keyboard you’d find in a church or a ballpark. We’re talking about the collection of tissues within the body that perform vital functions for life. Organs! Part 1 focuses on that warm red liquid inside of you, blood! Now blood is not technically an organ. But, according to Stan, it should be. Dr. Crooke covers how the blood cycle delivers nutrients and oxygen to other organs through the hemoglobin protein, the factors and checklist of blood clotting, and discusses a few of the countless mutations within blood cells that cause both common and rare diseases.
