You have studied a great deal about the workings of the human body throughout your Key Stage 2 science course. This topic is going to pull a few of those strands together and examine how our digestive and circulatory systems link together to make sure that all the hardworking cells across our body receive what they need to keep them working.
We'll revisit the digestion of food within the gut and how the digested nutrients are absorbed across the gut wall and into the bloodstream.
We'll examine how the dissolved nutrients, in the blood plasma, are carried to every cell in the body, through the system of arteries and capillaries, ensuring that each one receives the energy it needs in order to be able to operate.
Finally, we'll also touch on what happens to the wastes, like carbon dioxide and urea, that the cells create as they operate, and how those wastes are carried to certain organs to be removed from the body.
So, are you ready for this journey? Let's see where it goes!
