How Does Human Technology Affect Our Lives

Article 1 - About Us
For years, mankind has made several advancements in science, technology and medicine with uncountable achievements in each and every sector. These advancements have influenced our everyday life in a way that we never imagined. We, the people of the earth, have experienced over decades of breakthroughs to such an extent that we are now a click away from accessing unlimited information when compared to gathering and sharing of information in person like earlier times.
Development in the of human health sector has advanced by leaps and bounds so much that the new discoveries are being made based on analysis and results which are made accessible to the common public on a daily basis. We can now search for any abnormality on
There's one which we wear, our skin. It is the largest organ; adults carry an approximate of 8 pounds and 22 square feet of it. This flesh does more than just cover us; we would literally evaporate without it.

It acts as a hydrophobic, insulating shield, guarding the body against extremes of temperature, radiation, and harmful compounds. It also obstructs antimicrobial substances that prevent infection and aids in the manufacturing of vitamin D for converting calcium into healthy bones. Skin, on the whole, is a huge sensor enhanced with nerves for the brain to contact with the outside world. On similar lines, it allows us free movement, making it an amazingly adaptable organ.

There are three layers of the skin, outermost being epidermis. It comprises of keratinocytes, made of the protein keratin. These form the several layers that grow outwards as a renewal technique. Five weeks are required for reconstruction of newly created cells to work their way to the surface. There is a certain covering of dead skin commonly known as the stratum corneum and has variable thickness being more than ten times thicker on the soles of the feet than around the eyes. The upper layer harbors the defensive Langerhans cells a part of the immune system, which are alerted at the entry of a foreign agent like viruses and other infectious
Blood vessels here manipulate body temperature for favorable conditions by increasing blood flow to the skin to allow escaping body heat generated or by restricting the flow when it's cold. The integrated reticulum of nerve fibers and receptors analyze these feelings such as touch, temperature, and pain, assembling them to the brain.

The lower year of dermis houses hair follicles and glands with ducts that pass up all throughout the skin. There are sweat glands which are responsible for bringing down internal temperature through perspiration while fluctuating the body of the waste fluids urea and lactate, a mere excuse for control. There are certain Apocrine glands which produce scented sweat linked to sexual attraction that can also cause body odor, especially around the armpits as aforementioned. The sebaceous glands are responsible for the secretion of oil-like sebum for body scalp lubrication.

The last of skin's basal layer is the subcutis, which has large amounts of energy storage which is laid down as a fuel reserve in case of food shortage. It also works as insulation and protects us from knocks and
