The Deadliest Infectious Disease of All Time | Crash Course Lecture
Tuberculosis is often thought of as an old-timey disease, but in reality, it continues to kill over a million and a half people per year, despite its known cure. How did we get here, to a world where decades of work toward a cure stalled in its dissemination around the globe? And how can understanding the history of TB point us toward a different future? If you’ve been following author and TB-hater John Green in any way for the last year or so, this video is the deep dive you’ve been waiting for…

The Heart, Part 1 - Under Pressure: Crash Course Anatomy & Physiology #25
Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works. The heart’s ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries and bring it back to the heart through your veins. You'll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.

Immune System, Part 1: Crash Course Anatomy & Physiology #45
Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes -- the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we'll explain how all of these elements work together to save the day if you happen to slip on a banana peel.

Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works.

Why do animals do what they do? It’s a huge question, and in this episode, we’ll learn how scientists break it down. We’ll talk about the proximate and ultimate studies they use to understand animal behavior, and some of what they’ve learned along the way — including how much decision-making other animals are really doing.
Introduction: Animal Behavior 00:00

Ultimate Level 03:06
Innate Behaviors 04:30
Complex Behaviors 06:34
