Which is the Most Sensitive Organ in Our Body
The largest organ in the human body is the skin.
It is a huge and important organ. It is a fleshy surface which is covered with hair, nerves, glands and nails. It is made up of hair follicles that serve as anchors for hair strands in the skin.
It serves as a barrier between the outside and the inside of the human structure.
The thickness and texture of the skin vary.
The skin around the eyelids, for example, is as thin as paper, while the soles of the feet and palms are thick.
On our body’s surface, the skin covers an area of 20 square feet.
Important functions of the skin in the human body
The skin plays an important role in the human body.
Below are some of the most significant functions of the skin in the human body.
This is the skin’s primary and most significant function. It keeps microorganisms at bay, preventing them from entering the skin and causing harm.
Prevents the loss of water
Humans have thicker skin, which means they lose less water. Human skin thickens in deserts to prevent water loss due to dry air. Organisms with thin skin are more likely to lose water all of the time, thus they must stay near water to keep it from drying out.
Touch, heat, pressure, cold, pain, and pleasure are all sensed through the skin. These impulses are sent to the brain via a network of nerves. As a result, we can respond correctly to a given stimuli.
Perspiration causes our skin to lose water and cool down, reducing heat from the body. It also enables heated blood to travel to the skin’s surface, where its heat is radiated outward. The “goosebumps” phenomena is also a temperature regulation reaction.
Camouflage is a phenomena in which the skin of many animals develops colours and patterns that blend in with their environment and protect them from predators.
The skin’s tissues can store fats and water. Our bodies benefit from the extra insulation provided by them.
Smell Signals Excreted
Our skin’s sweat can also be used as a signal to other creatures. Many animals mark their territory by secreting a fragrance that carries information about their age, health, gender, and availability to mate through glands in their skin.
