Question

I REALLY NEED HELP! this is going to be a little confusing but i hope i make it look like a easy question.

1. The circulatory system filters WHAT from the blood before it becomes toxic?


2.The digestive system removes WHAT that can damage the body?


3.The nervous system interacts with WHAT, which controls secretion of the hormones that help WHAT?

Answer 1

1. lymph

2. hydroelectric acid

3. endocrine system, hormones help regulate your body's processes

Step-by-step explanation:

1. As the lymph makes its way back toward the heart, it has to pass through the lymph nodes (small, round masses that filter out bacteria, waste, and other toxins and contain white blood cells).

2. When food reaches the stomach, much of it is sterilized by the hydroelectric acid in digestive juices.

3. Hormones are molecules produced by the endocrine system that send messages to various parts of the body. They help regulate your body's processes, like hunger, blood pressure, and sexual desire. While hormones are essential to reproduction, they are fundamental to all the systems of your body.
