Explanation:
Let’s solve each part step by step.
Part 1: Matching systems to organs
We need to match each body system with the correct list of organs (a–f).
-
The Circulatory System: This system moves blood around the body. It includes the heart, blood, and blood vessels.
→ That matches
d.
-
The Respiratory System: This system helps us breathe. Organs include mouth, pharynx, lungs, and bronchi.
→ That matches
f.
-
The Digestive System: This breaks down food. Organs: mouth, salivary glands, esophagus, stomach, liver, intestines.
→ That matches
b.
-
The Skeletal System: Provides structure and support — made of bones.
→ That matches
e.
-
The Muscular System: Made of muscles that help us move.
→ That matches
c.
-
The Nervous System: Controls the body and sends signals — brain, spinal cord, nerves.
→ That matches
a.
So the matches are:
- Circulatory → d
- Respiratory → f
- Digestive → b
- Skeletal → e
- Muscular → c
- Nervous → a
Part 2: Answering the questions
- *Helps humans turn their food into energy?*
That’s the
Digestive System — it breaks food down so the body can use it for energy.
- *Helps humans breathe?*
That’s the
Respiratory System — it brings oxygen in and removes carbon dioxide.
- *Controls other body systems?*
That’s the
Nervous System — it sends signals to control everything (like heartbeat, breathing, movement).
- *Provides structure for the body?*
That’s the
Skeletal System — bones hold us up and protect organs.
Final Answer:
1. The Circulatory System — d
The Respiratory System — f
The Digestive System — b
The Skeletal System — e
The Muscular System — c
The Nervous System — a
2.
- helps humans turn their food into energy? → Digestive System
- helps humans breath? → Respiratory System
- controls other body systems? → Nervous System
- provides structure for the body? → Skeletal System
