Comparative Anatomy: Integumentary System
Humans vs. Fish
Human Integumentary System Summary:
Function: Excretion, protection, temperature regulation, sensation, metabolism, blood reservoir
Location: Skin, hair, nails, glands, and nerves
Structure: Epidermis, dermis, hypodermis
Fish Integumentary System Summary:
Function: Osmotic balance, physical protection, site of coloration, respiration (for some)
Location: Skin
Structure: Epidermis is avasular and contains mucous cells. Dermis contains blood vessels, nerves, sense organs, connective tissue, and pigment cells
Compare/Contrast
Similarity: Both provide immense amount of protection to the body
Difference: Human skin does help with respiration
Humans vs. Reptiles
Human Integumentary System Summary:
Function: Excretion, protection, temperature regulation, sensation, metabolism, blood reservoir
Location: Skin, hair, nails, glands, and nerves
Structure: Epidermis, dermis, hypodermis
Reptiles Integumentary System Summary:
Function: Protection, shedding and growing of new scales, heat exchange
Location: Skin
Structure: Beta keratin and pliable alpha keratin
Compare/Contrast:
Similarity: Both provide the body with protection
Difference: Human integumentary system does not have scales
Humans vs. Amphibians
Human Integumentary System Summary:
Function: Excretion, protection, temperature regulation, sensation, metabolism, blood reservoir
Location: Skin, hair, nails, glands, and nerves
Structure: Epidermis, dermis, hypodermis
Amphibian Integumentary System Summary:
Function: Vital respiratory organ, supplied with blood vessels, and lymph spaces
Location: Skin
Structure: Two-layered dermis. Outer and looser stratum spongiosum and an inner stratum compactum
Compare/Contrast:
Difference: Amphibians use skin as respiratory organ
Similarity: Both systems act as blood resovoir
Humans vs. Birds
Human Integumentary System Summary:
Function: Excretion, protection, temperature regulation, sensation, metabolism, blood reservoir
Location: Skin, hair, nails, glands, and nerves
Structure: Epidermis, dermis, hypodermis
Birds Integumentary System:
Structure: Epidermis is thin, delicate, and clothed in feathers. The thin epidermis is mostly a network of connective tissue fibres and muscle fibres
Function: Barrier, thermal insulation, sensation, pigments for protection, converts sunlights into vitamin D
Location: Skin, feathers, claws, and beak
Compare/Contrast:
Similarity: Both provide protection for the body
Difference: Human skin does not have feathers
