Body systems worksheet - Free Printable

Let's solve this worksheet step by step. The task is to categorize the listed organs into their corresponding body systems:
- Nervous System
- Respiratory System
- Digestive System
- Skeletal System
- Circulatory System

We are given a list of organs and structures, and we need to place each one in the correct system.

🔹 Step 1: Understand Each Body System

#### Nervous System
Controls body functions via nerves and signals. Includes:
- Brain
- Spinal cord
- Nerves

#### Respiratory System
Involved in breathing and gas exchange. Includes:
- Lungs
- Trachea (windpipe)
- Bronchi
- Nasal cavity
- Pharynx
- Larynx

#### Digestive System
Breaks down food and absorbs nutrients. Includes:
- Mouth (not listed)
- Esophagus
- Stomach
- Intestines
- Liver
- Pancreas
- Anus

#### Skeletal System
Provides structure and support. Includes:
- Bones like skull, tibia, femur, humerus, ribs, vertebrae

#### Circulatory System
Transports blood, oxygen, nutrients. Includes:
- Heart
- Blood vessels: arteries, veins

🔹 Step 2: Categorize Each Organ

Now let’s go through the list:

| Organ / Structure | System |
|-------------------|--------|
| PANCREAS | Digestive |
| TIBIA | Skeletal |
| HEART | Circulatory |
| VERTEBRAL COLUMN | Skeletal |
| SPINAL CHORD | Nervous |
| STOMACH | Digestive |
| BRONCHI | Respiratory |
| NERVES | Nervous |
| FEMUR | Skeletal |
| NASAL CAVITY | Respiratory |
| LUNGS | Respiratory |
| LIVER | Digestive |
| HUMERUS | Skeletal |
| INTESTINES | Digestive |
| BRAIN | Nervous |
| SKULL | Skeletal |
| TRACHEA | Respiratory |
| VEINS | Circulatory |
| ANUS | Digestive |
| ESOPHAGUS | Digestive |
| PHARYNX | Respiratory |
| LARYNX | Respiratory |
| RIBS | Skeletal |
| ARTERIES | Circulatory |

🔹 Step 3: Fill in the Boxes

Now assign them to the correct boxes.

---

- Esophagus

> (Break down food and absorb nutrients.)

---

#### ✔ Skeletal System
