Lecture Notes

Pictured here on this slide you can see the entire circulatory system: the heart and the lungs, but also the arteries, the veins, and all of the tissues that are receiving nutrients from this, and oxygen in particular from the circulatory system. And so we're not going to talk a whole lot on this slide about it, but we'll talk about each of these components and how they're affected by improvements in your cardiorespiratory fitness on the next few slides.
