Answer:
What are the three layers of the integument and what tissue is each made of?
The integument is the outer covering of the body and includes the skin, hair, and nails. It has three main layers:
The epidermis: This is the outermost layer of the integument. It is made of stratified squamous epithelial tissue and is constantly shedding and regenerating.
The dermis: This is the layer of the integument that lies beneath the epidermis. It is made of dense irregular connective tissue and contains blood vessels, nerves, sweat glands, and sebaceous glands.
The hypodermis (also called the subcutaneous layer): This is the innermost layer of the integument and lies beneath the dermis. It is made of loose connective tissue and fat cells, which help to insulate the body and protect it against temperature changes. It also serves as an energy reserve and helps to anchor the skin to underlying structures.
Answer:
Explanation:
The integument is the outer layer of the body that protects against external threats and helps regulate the body's temperature. It is made up of three layers:
The epidermis: This is the outermost layer of the integument, and it is made of stratified squamous epithelium, a type of tissue that is composed of multiple layers of flat, scale-like cells. The epidermis provides a protective barrier against the environment and helps regulate the body's water balance.
The dermis: The dermis is the middle layer of the integument, and it is made of dense connective tissue. It contains blood vessels, nerve endings, sweat glands, sebaceous glands, and hair follicles, and it provides support and elasticity to the skin.
The hypodermis: The hypodermis is the innermost layer of the integument, and it is made of loose connective tissue. It helps anchor the skin to the underlying tissues and provides insulation to help regulate the body's temperature. The hypodermis also contains fat cells, which help store energy and provide cushioning and protection to the body.
Overall, the three layers of the integument work together to provide protection and support to the body, as well as regulate temperature and water balance.
