Term
| Identify 3 characteristics of gas exchange in arthropods. |
|
Definition
- Each segment of the insect has lip-like opening called spiracles, which lead to a tree-like branching of tubes called tracheoles which divide until their microscopic endings reach EACH cell.
- Can be closed to prevent water loss
- Muscles can be used to pump gasses into and out of body
