Integumentary System Functions
This system helps regulate body temperature by sweating or shivering.
What is the integumentary system?
This outermost layer of the skin contains keratinocytes and melanocytes.
What is the epidermis?
The skeletal system protects this vital organ located in the skull.
What is the brain?
The femur and humerus are examples of this type of bone.
What are long bones?
The shoulder and hip are examples of this type of joint that allows movement in all directions.
What are ball-and-socket joints?
The skin provides this type of vitamin when exposed to sunlight.
What is vitamin D?
This layer contains hair follicles, sweat glands, and sebaceous glands.
What is the dermis?
The ribcage protects these two essential organs in the chest.
What are the heart and lungs?
The skull, ribs, and sternum are examples of this type of bone that protects organs.
What are flat bones?
These tissues connect bones to other bones.
What are ligaments?
The integumentary system protects the body from these three external threats.
What are injury, infection, and UV radiation?
This innermost layer stores fat and provides insulation.
What is the hypodermis (or subcutaneous layer)?
Bones store these two minerals essential for strength and metabolic functions.
What are calcium and phosphorus?
This part of a long bone contains yellow marrow for fat storage.
What is the medullary cavity?
These cells break down old or damaged bone tissue.
What are osteoclasts?
Sensory receptors in the skin allow you to detect these three sensations.
What are touch, pain, and temperature?
This layer contains the majority of the skin’s sensory nerves and blood vessels.
What is the dermis?
Blood cells are produced in this type of marrow found in spongy bone.
What is red marrow?
This dense outer layer of bone provides strength and support.
What is compact bone?
These cells build new bone tissue.
What are osteoblasts?
The integumentary system plays a key role in preventing these microorganisms from entering the body.
What are pathogens or bacteria?
Keratinocytes in the epidermis produce this protein that strengthens and waterproofs the skin.
What is keratin?
Bones provide attachment points for these tissues to allow movement.
What are muscles?
Found at the ends of long bones, this part contains red marrow for blood cell production.
What is the epiphysis?
This flexible tissue cushions joints and provides structure in the nose and ears.
What is cartilage?
