Step-by-step solution for: Body system interactions worksheet ANSWER KEY.doc - some Body ...
It looks like you've uploaded an image of a worksheet titled "Body system interactions" with a table that lists various body systems and asks how they interact. However, the actual content of the image (specifically the text in the "How they interact" column) is not visible or readable in your message.
To help you properly, I’ll explain how to solve this type of problem and provide examples based on common biological knowledge.

The goal is to describe how each body system interacts with other systems to maintain homeostasis and support life.
Each row has:
- A body system (e.g., circulatory, respiratory, digestive).
- A blank space for "How they interact", where you need to write how that system works with others.
---
For each system, ask:
1. What does it do?
2. Which other systems does it depend on?
3. How does it support other systems?
Let’s go through common systems and their interactions:
---
- Function: Transports blood, nutrients, oxygen, hormones, and waste.
- Interactions:
- Works with respiratory system: picks up O₂ from lungs and delivers CO₂ to be exhaled.
- Works with digestive system: carries nutrients absorbed from the gut.
- Works with excretory system: removes metabolic wastes (e.g., urea) to kidneys.
- Works with endocrine system: transports hormones to target organs.
- Works with immune system: carries white blood cells and antibodies.
