Storing and excreting nutrients Flashcards
What are the four sources of nutrients for the body?
Food, water, the environment, and the sun
Where do most of our nutrients come from and what is it important we do to regulate this?
Most nutrients comes from food/our diet, so it is important to eat a balanced diet to provide our body with all the nutrients in correct amounts.
Describe simple carbohyrates.
Used by the body as a quick energy source. If we don’t use up simple carbs, they are turned into fats to store for later.
Describe complex carbohydrates.
Provide a longer lasting energy source. Broken down into simple carbs for energy. This is a slow process and requires energy. Any excess is converted to fats.
Describe fats.
Our bodies need some fats to function properly. However, excess fats are stored under the skin, around organs, and int he bloodstream.
