1. Observe: Look through the descriptions of the large and small organs. A. Which of the large organs allow nutrients and water to pass through their walls

The small intestine and large intestine

Explanation:

The small and large intestines were designed to allow nutrients to pass through their walls.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
