Khan Academy

I've been watching some science videos on Khan Academy (they have many more subjects besides science). So here is a very brief description of what I have watched.




Here he (the teacher) takes you through the hearts process step by step. This mainly talks about the way blood flows through the heart, and how it make sure that blood doesn’t go the wrong way. He also talks about the layers of the heart (its outer wall layers), and how when your maturing a balloon slowly starts to wrap around your heart.
Please ignore the captions, that was just me doing bad screenshots.



He teaches you what the lungs look like (like the cardiac notch), and also tells you about how different the two lungs are compared to each other (how the right long has 3 sections and the left lung only has 2, and other things). He also teaches you the bronchial tree and about alveoli and their purpose.



The next section (I’ve only started and haven’t finished the section) talks about whats in blood and what they do when they take your blood. A different teacher tells us what the blood types are and who can accept what (blood type) and who can give to whom.




This is all on Khan Academy and there is a bunch more besides science of the body, there is technology and math and a bunch of other subjects.
