Explore how your body works through the study of body anatomy

How does the body work? What is it made of? What are the different parts of the human body and what are their functions?

From cells to organ systems, this course will introduce you to the basic components that make up the human body.

You’ll discover what molecular structures are, and classify different types within the body.

As you learn more about cell structure, you’ll find out about human tissue and its function, and explore the different organs systems within the body and what they do.

You’ll also gain basic physiological knowledge and learn how your body works, and how to influence it.

I want to tell you a little bit about what you can expect to learn through this programme, which is made up of a range of short courses. Each one lasts about three weeks. In this programme, we’re going to take you from the smallest part of the body, the DNA, and through the cells– into how the cells cluster to make tissues. And then how the tissue makes into a bigger system called an organ. And that’s things like your heart, your brain, and how they all interact together. Why would you want to study that, is really quite straightforward.

Skip to 0 minutes and 42 seconds We want to know why you maybe got a cold last week, but your best friend who sits next to you all day, they didn’t catch it. What’s the difference in your bodies? Why is one of you more susceptible? We’ll also look how does what you eat turn into making the body. So how come you eat food, and then your hair grows, your nails grow, your bones are turning over? We’re making new blood every day. How does the body do that? It’s an amazing process. And we’re to take you through exploring how those steps happen.

Skip to 1 minute and 13 seconds So maybe you’re considering going on to do post-graduate studies, and that would be something like a master’s or even possibly a PhD, but the studies you want to do require science in the entrance requirement. And you might not have either enough science yet, or you maybe haven’t covered science in your undergraduate degree. This course will allow you to gain credits from the University of Aberdeen, which we recognise by other universities, to enable you to apply there to study for a master’s programme. And in particular, it’s one of the entrance requirements for coming onto University of Aberdeen to study with our human nutrition programme or our clinical nutrition programme.
