I'm going to walk you through the topics we'll cover in this chapter — Page 21, Lesson 32

This is the start of Chapter 2, which is all about Blood Circulation. I'm going to walk you through the topics we'll cover in this chapter. This is a table of contents, so it's our roadmap for the entire section. We begin with The Blood itself, and then we'll look at its Composition — what it's actually made of. Then we move to the pump, The Heart, and how it works. A critical part of this is Oxygen Carriage — how the blood transports oxygen to your tissues. And then the flip side, the Carriage of Carbon Dioxide, the waste product we need to get rid of. We'll then study The Circulation System as a whole — the pipes and the route the blood takes. After that, we look at What Can Go Wrong, which includes System Failures and the Factors Predisposing to Heart Attack. We'll also cover Insufficient Oxygen Carried, and two specific causes of that: Carbon Monoxide and Smoking. Then we get into Blood Pressure — what it is and how it's controlled. That leads to Pressoreceptors and their Function Maintaining Blood Pressure — these are the sensors that help regulate it. There's a practical section on Donating Blood and Aircrew — the rules and considerations for pilots. And finally, Pulmonary Embolism, a serious condition where a blood clot blocks an artery in the lung. The chapter ends with Questions and Answers for you to test yourself. So, that's the full scope of Chapter 2. We'll start at the very beginning with the blood itself. Let's go.
