A. Identify the layers of the skin

The diagram shows a cross-section of the skin with three main layers labeled by colored arrows:

- Blue arrow (top layer) → Epidermis
This is the outermost layer of the skin, made up of stratified squamous epithelium. It protects the body from pathogens and environmental damage.

- Red arrow (middle layer) → Dermis
This layer lies beneath the epidermis and contains blood vessels, nerves, hair follicles, sweat glands, and connective tissue. It provides strength and elasticity to the skin.

- Green arrow (bottom layer) → Hypodermis (Subcutaneous layer)
This is the deepest layer, composed mainly of adipose (fat) tissue and loose connective tissue. It insulates the body and cushions internal organs.

✔ So, fill in:
- Blue → Epidermis
- Red → Dermis
- Green → Hypodermis

B. Choose the word being described in each sentence

Now match the descriptions with the correct term. We’ll go one by one.

1. It acts as a barrier from the outside environment.
→ Epidermis
*Reason:* The epidermis is the outermost layer that protects the body from microbes, UV radiation, and dehydration.

2. It waterproofs and protects the cells and tissues that lie underneath.
→ Epidermis
*Reason:* The stratum corneum (outer part of the epidermis) is made of dead keratinized cells that prevent water loss and block entry of harmful substances.

3. It consists of connective tissues that prevent the skin from tearing and enables the skin to return to its normal state after being stretched.
→ Dermis
*Reason:* The dermis contains collagen and elastin fibers that give strength and elasticity.

4. It covers the palms of the hands and soles of the feet.
→ Thick skin
*Note:* This refers to skin that has a thicker epidermis and contains ridges (like fingerprints). Thick skin is found on palms and soles.

5. This refers to the fat tissue below the dermis that insulates the body from cold temperatures and provides shock absorption.
→ Hypodermis
*Reason:* The hypodermis is rich in adipose tissue, which serves as insulation and cushioning.

6. They act as a protective plate over the fingertips and toes.
→ Nails
*Reason:* Nails are hardened structures made of keratin that protect the tips of fingers and toes.

7. The outer layer of the skin.
→ Epidermis
*Reason:* As previously mentioned, the epidermis is the outermost layer.
