Skin Basics
This is the largest organ of the human body.
What is the skin?
These structures grow from hair follicles and help protect the skin and regulate temperature.
What is hair?
The skin helps protect the body from this.
What are injury, microorganisms, and harmful substances?
A burn that affects only the outermost layer of the skin is called this.
What is a first-degree (superficial) burn?
Red, painful skin without blisters is commonly associated with this type of burn.
What is a first-degree burn?
The outermost layer of the skin is called this.
What is the epidermis?
These glands produce an oily substance that lubricates the skin and hair.
What are sebaceous glands?
Sweating helps the body perform this function.
What is temperature regulation?
This type of burn involves the epidermis and part of the dermis and commonly produces blisters.
What is a second-degree (partial-thickness) burn?
Blister formation is commonly associated with this type of burn.
What is a second-degree burn?
The deeper layer of skin that contains blood vessels, nerves, glands, and hair follicles is called this.
What is the dermis?
These glands produce sweat and help regulate body temperature.
What are sweat glands?
The skin contains sensory receptors that allow a person to detect this.
What are touch, pressure, pain, and temperature?
A burn that destroys the epidermis and dermis and may extend into deeper tissues is called this.
What is a third-degree (full-thickness) burn?
Severe burns can cause significant loss of this fluid from the body.
What is plasma/fluid?
This layer lies beneath the dermis and is primarily composed of adipose and connective tissue.
What is the subcutaneous layer (hypodermis)?
These structures are hard, keratinized plates that protect the ends of fingers and toes.
What are nails?
The skin helps the body produce this vitamin when exposed to sunlight.
What is vitamin D?
Which degree of burn is often characterized by white, brown, or black, leathery skin and loss of sensation in the burned area?
What is a third-degree (full-thickness) burn?
A patient with a major burn is at high risk for this type of shock because of significant fluid loss.
What is hypovolemic shock?
This protein gives the epidermis strength and helps make the skin waterproof.
What is keratin?
This gland releases sweat onto the skin's surface through ducts.
What is an eccrine sweat gland?
Blood vessels in the dermis can dilate or constrict to help regulate this.
What is body temperature?
A burn that extends through the skin into muscle, bone, or other deep tissues is classified as this.
What is a fourth-degree burn?
This method is commonly used to estimate the percentage of total body surface area burned.
