Stop n' Jot

Function: Your digestive system breaks nutrients, such as carbohydrates, fats and lipids, into building blocks which are small enough to diffuse (move) into the bloodstream and then into each of your cells.

The digestive system uses mechanical digestion (chewing, churning), acids and enzymes to break down organic molecules into their building blocks. These organic molecules diffuse (move) from your small intestines into your blood stream. Water diffuses from your large intestines into your blood stream.

1) Diffusion of sugar 🍚 occurs from small intestines to capillaries and then capillaries to cells.

2) Diffusion of water 💧 occurs from large intestines to capillaries and then capillaries to cells

Before runner 0358 ran the race she went to her doctor to make sure she was healthy enough for a marathon . The doctor took a blood sample from the runner a week before the race. In our next lesson, we will review the results and see if the organic molecules in the runner's food was breaking down and diffusing into her blood.
