Final answer:
The colon is the part of the large intestine that helps fight parasites from the previous digestive tract.
Step-by-step explanation:
The part of the large intestine that helps fight parasites that have survived the previous digestive tract is the colon.
The colon is the longest part of the large intestine and is responsible for absorbing water and electrolytes from undigested food. It also plays a role in eliminating waste material from the body.
While the appendix is a small pouch-like extension located near the junction of the small and large intestines, it does not have a significant role in fighting parasites or digesting food.
