Structure of the Integumentary System
The integumentary system is the home to the largest organ of the human body, the skin. The skin is formed by two or more tissue types, meeting the qualifications of an organ. The distinct layers of the skin include the epidermis and dermis. The skin is securely anchored to underlying surfaces through the vast network of the hypodermis or subcutaneous layer.
The third, deeper layer, lying under the dermis, is the subcutaneous layer. This layer consists primarily of fat and connective tissue. Let's take a look at the cell variability found in the connective tissue.
