Let's solve this worksheet step by step.
The task is to
identify the name of each bone (or group of bones) shown in the images and
name the organs they protect.
---
1. First Image: Pelvis
-
Name of the bone:
Pelvis (or pelvic girdle)
-
Organs they protect:
Reproductive organs, bladder, and rectum
*(In females, it also protects the uterus and ovaries; in males, the prostate and testes are nearby but not directly inside the pelvic cavity.)*
> The pelvis forms a bowl-like structure that protects the lower abdominal organs.
---
2. Second Image: Skull
-
Name of the bone:
Skull (cranium)
-
Organs they protect:
Brain
> The skull encloses and protects the brain, which is vital for controlling all body functions.
---
3. Third Image: Ribcage
-
Name of the bone:
Rib cage (ribs and sternum)
-
Organs they protect:
Heart and lungs
> The rib cage forms a protective cage around the thoracic cavity, shielding the heart and lungs from injury.
---
4. Fourth Image: Spine (Spinal Column)
-
Name of the bone:
Spinal column (vertebral column)
-
Organs they protect:
Spinal cord
> The spinal column is made up of vertebrae that surround and protect the spinal cord, which is part of the central nervous system.
---
Final Answer Table:
| Image | Name of the bone | Organs they protect |
|-------|------------------------|---------------------------------------------|
| 1 | Pelvis | Reproductive organs, bladder, rectum |
| 2 | Skull | Brain |
| 3 | Rib cage | Heart and lungs |
| 4 | Spinal column | Spinal cord |
---
✔ Explanation Summary:
Bones act as natural shields for vital organs. The
skull protects the brain, the
rib cage protects the heart and lungs, the
pelvis protects reproductive and excretory organs, and the
spinal column protects the spinal cord. This protective function is essential for survival.
