The integumentary system comprises the outermost layer of an animal body. Skin is the largest organ of humans and frogs. Skin acts as a protective outer covering in both frogs and humans. The main difference between the integumentary system of frogs and humans is that the skin acts as a respiratory organ in frogs but not in humans.
Difference between Frog and Human Integumentary System
The table below shows the main differences between frogs and the human integumentary systems.

Skin provides protection and is also involved in respiration |
Skin is not involved in respiration |

The skin of frog secretes poisons and mucus |
Skin in humans has sweat glands and sebaceous glands |
|
It absorbs water |
It is impermeable to water |

It cannot camouflage |
|
The skin of frogs is primarily made up of epidermis and dermis |
The skin of humans is made up of three layers, epidermis, dermis and hypodermis |
|
Frogs lack hair or fur |
The human skin is covered by hair |
Frog Integumentary System
The integumentary system in frogs performs various functions such as protection, respiration, osmoregulation, and acts as a sensory organ to perceive stimuli. The skin of frogs is moist and slippery. It contains various glands that secrete mucus and poison. The skin is composed of epidermis and dermis. The epidermis is composed of stratum corneum and the dermis is made up of stratum spongiosum and stratum compactum, which is made up of connective tissue. The skin contains various ectodermal and cutaneous glands, blood vessels, and chromatophores.
The skin of frogs also acts as a respiratory organ. In water, they perform cutaneous respiration, i.e. through the skin. Oxygen dissolved in water is diffused through the skin. During aestivation and hibernation respiration takes place through the skin. The moist skin helps in the gaseous exchange. The skin is extremely permeable to water and they can absorb or lose water through the skin. They adapt to their surroundings through camouflage.
Human Integumentary System
Skin is the largest organ of the human body. It acts as a mechanical barrier and helps in maintaining the internal environment. It is also involved in thermoregulation, sensory perception and vitamin D synthesis.
The human integumentary system comprises the epidermis, dermis, hypodermis, various glands, sensory receptors, hair and nails.
The epidermis is made up of five layers of stratified squamous epithelial cells. They are stratum corneum, stratum granulosum, stratum spinosum, stratum basale and stratum lucidum. It does not contain blood vessels.
The dermis is made up of connective tissue. It contains blood vessels, nerves, various glands and hair follicles. The hypodermis is present between the dermis and different organs. It is also known as the subcutaneous layer. It is made up of areolar and adipose tissue. The human skin contains various exocrine glands such as sweat glands, sebaceous glands, mammary glands, etc.
Skin is the first line of defence and helps in maintaining homeostasis. The human skin does not take part in gaseous exchange like frogs, i.e. they do not perform cutaneous respiration.
