The Integumentary System Worksheet | PDF - Free Printable

Based on the analysis of the diagram, here is the solution for labeling the integumentary system:

The diagram shows a cross-section of the skin with various structures labeled. By identifying each part based on its location and appearance, we can match them to the correct terms from the word bank.

Here is the completed labeling:

- Top Left: This line points to the outermost layer of the skin. This is the Epidermis.
- Top Right (top line): This line also points to the outermost layer, confirming it as the Epidermis.
- Top Right (middle line): This line points to the small opening on the surface of the skin where sweat exits. This is the Sweat Pore.
- Top Right (bottom line): This line points to the coiled gland deep in the dermis that produces sweat. This is the Sweat Gland.
- Middle Left (top line): This line points to the cluster of glands associated with the hair follicle that secrete oil. This is the Sebaceous (Oil) Gland.
- Middle Left (bottom line): This line points to the muscle attached to the hair follicle that causes the hair to stand up. This is the Erector Muscle (also known as the arrector pili muscle).
- Middle Right (top line): This line points to the blue, oval-shaped structure in the dermis, which represents a blood vessel carrying deoxygenated blood. This is the Vein.
- Middle Right (bottom line): This line points to the boundary between the dermis and the subcutaneous layer. The layer below is the Subcutaneous tissue.
- Bottom Left (top line): This line points to the red and blue pair of vessels in the subcutaneous layer. The red vessel is an Artery, and the blue vessel is a Vein. Since "Vein" is already used, this must be the Artery.
- Bottom Left (bottom line): This line points to the small, dark spot within the epidermis, which represents the pigment-producing cells. This is Melanin.
- Bottom Middle: This line points to the thick, inner layer of the skin, which contains nerves, blood vessels, and glands. This is the Dermis.
- Bottom Right: This line points to the nerve ending or receptor in the dermis. This is the Nerve.

In summary, the labels are assigned as follows:
- Top Left: Epidermis
- Top Right (top): Epidermis
- Top Right (middle): Sweat Pore
- Top Right (bottom): Sweat Gland
- Middle Left (top): Sebaceous (Oil) Gland
- Middle Left (bottom): Erector Muscle
- Middle Right (top): Vein
- Middle Right (bottom): Subcutaneous
- Bottom Left (top): Artery
- Bottom Left (bottom): Melanin
- Bottom Middle: Dermis
- Bottom Right: Nerve
