Explain how nutrients are absorbed into the bloodstream.

• Nutrients are absorbed directly from the mouth into the bloodstream.

• Nutrients are absorbed through the skin after being exposed to sunlight.

• Nutrients are absorbed into the bloodstream through the walls of the small intestine after being broken down into simpler forms.

• Nutrients are absorbed in the stomach without any breakdown.
