Middle Image: Circulatory and Digestive Systems

This image shows four figures representing different systems related to circulation and digestion.

1. Figure 1 (Leftmost):
- Name of the Body System: Nervous System
- Main Function: Controls and coordinates body activities through electrical signals.
- Main Organ Involved: Brain

2. Figure 2 (Second from Left):
- Name of the Body System: Circulatory System
- Main Function: Transports blood, nutrients, oxygen, and waste throughout the body.
- Main Organ Involved: Heart

3. Figure 3 (Third from Left):
- Name of the Body System: Digestive System
- Main Function: Breaks down food into nutrients and eliminates waste.
- Main Organ Involved: Stomach or Intestines

4. Figure 4 (Rightmost):
- Name of the Body System: Urinary System
- Main Function: Filters blood to produce urine and eliminate waste.
- Main Organ Involved: Kidneys
