Respuesta :
The statement which is false about the intergumentary system is option D. "Keratin is the pigment responsible for skin color."
Even though the skin color of human beings is affected y different substances, the pigment melanin is responsible for it. Melanin is produced within the skin in cells known as melanocytes and it determines of the skin color of darker-skinned humans.
For instance, the skin color of those who have light skin is determined primary by the bluish-white connective tissue placed beneath the dermis and by the hemoglobin which circulates in the veins of the dermis.
The statement that is FALSE about the integumentary system is that "Keratin is the Pigment responsible for skin color"
Further Explanation:
Integumentary system
It is one of the organ system whose functions includes regulating body temperature, retaining body fluids, eliminating waste products and also protecting the body against disease causing pathogens.
Integumentary system is composed of the skin, glands, hair, nails, and nerves.
The Skin
It is the largest organ in the body and the main part of the integumentary system.
The Skin is made up of three layers;
- The Dermis
- The Epidermis
- The Hypo-dermis
The Epidermis
This is outermost layer of the skin with dermis and hypodermis underneath it.
The epidermis covers the whole body and protects the deeper layers of the skin from external environment and mechanical damage.
Specialized cells of the Skin
Epidermis contains some specialized cells that helps in the functioning of the skin.
These cells include;
Melanocytes
They are specialized cells which make a pigment known as melanin. The pigment is responsible for the protection of the skin from dangerous ultra-violet rays from the sun.
Keratinocytes
They are other specialized cells that give rise to a protein known as keratin.
Protein keratin is responsible making the skin tough and water-resistant
Langerhans cells
These are specialized cells whose role is detecting and fighting pathogens that may try to enter the body through the skin.
Merkel cells
Merkel cells are specialized cells that take part in sense of touch.
