The skin is the body’s largest organ, made of water, protein, fats and minerals. Your skin protects your body from germs and regulates body temperature
Three layers of tissue make up the skin:
Epidermis, the top layer.
Dermis, the middle layer.
Hypodermis, the bottom or fatty layer.
The epidermis:
Acts as a protective barrier: The epidermis keeps bacteria and germs from entering your body and bloodstream and causing infections. It also protects against rain, sun and other elements.
Makes new skin: The epidermis continually makes new skin cells. These new cells replace the approximately 40,000 old skin cells that your body sheds every day. You have new skin every 30 days.
Protects your body: Langerhans cells in the epidermis are part of the body’s immune system. They help fight off germs and infections.
Provides skin color: The epidermis contains melanin, the pigment that gives skin its color.
The dermis makes up 90% of skin’s thickness. This middle layer of skin:
Has collagen and elastin: Collagen is a protein that makes skin cells strong and resilient. Another protein found in the dermis, elastin, keeps skin flexible. It also helps stretched skin regain its shape.
Grows hair: The roots of hair follicles attach to the dermis.
Keeps you in touch: Nerves in the dermis tell you when something is too hot to touch, itchy or super soft. These nerve receptors also help you feel pain.
Makes oil: Oil glands in the dermis help keep the skin soft and smooth.
The bottom layer of skin, or hypodermis, is the fatty layer. The hypodermis:
Cushions muscles and bones: Fat in the hypodermis protects muscles and bones from injuries when you fall or are in an accident.
Has connective tissue: This tissue connects layers of skin to muscles and bones.
Helps the nerves and blood vessels: Nerves and blood vessels in the dermis (middle layer) get larger in the hypodermis.-

Great description, it is the largest organ even though we often dont see it as one. isnt it amazing all that our bodies do and how they function together?!

Good covering all the bases. Also, sleeping is important for a healthier-looking skin, supposedly skin renewal is most active during sleep.

The skin is the largest organ of the human body and it’s structure is composed of three main layers: the epidermis, the dermis, and the subcutaneous tissue (hypodermis). Each layer plays a crucial role in maintaining the body’s integrity, protecting against external threats, regulating temperature, and providing sensory information.
The first layer, the epidermis, acts as a protective barrier against pathogens, UV radiation, and other environmental factors. Comprised primarily of keratinocytes, the epidermis undergoes constant renewal through cell division in the basal layer. As cells move towards the surface, they undergo a process of keratinization, forming a tough, impermeable layer of dead skin cells that helps prevent water loss and protect against external aggressors.
Beneath the epidermis lies the dermis, a thicker layer containing blood vessels, nerves, hair follicles, and glands. Fibrous proteins such as collagen and elastin provide structural support and elasticity. The dermis houses important sensory receptors that detect pressure, temperature, and pain, contributing to our ability to interact with the environment.
The subcutaneous tissue, or hypodermis, is the deepest layer and consists mainly of adipose (fat) tissue. It serves as an insulator, regulating body temperature, and provides a cushion against mechanical trauma. Additionally, the hypodermis stores energy in the form of fat, acting as a reservoir for fuel.
All these layers work in harmony to maintain homeostasis, protecting the body from external threats, regulating temperature, and facilitating sensory perception.

Great info! The skin is such an interesting organ, I read that it regenerates itself approximately every 27 days.

Great description Steve! The skin plays an essential part in our overall well-being, despite us overlooking it as a significant organ.

The skin serves several important functions in our body, it’s the largest organ in the human body and it’s the contains sensory receptors that send signals to the central nervous system and that’s how we feel things. There’s 3 layers of skin: Epidermis, Dermis and Hypodermis.
Epidermis: upper part or outer layer. It’s mainly made of skin cells that constantly die and get replaced with new cells regularly. This layer provides a waterproof barrier against microbes, this layer also contains melanin, which determines the color of your skin. The more melanin you have, the darker your skin will be. Melanin is important because it protects our skin from harmful sun.
Dermis: the second layer of skin. Contains hair follicles and sweat glands, tough connective tissue and nerve endings. The nerve endings help send message to the brain regarding what you touched and the brain decides how to respond. For example, if you touch something hot, like boiling water, then the nervous system will tell the brain to move away from it. The sweat glands is where the sweat is generated and its released through the epidermis through the pores. Sweat is important as it helps us to regulate our body temperature. For example, when you become too hot then you will sweat more so your body can cool down.
Hypodermis: Third layer and also called subcutaneous tissue. This layer is mainly made up of fat and connective tissues. Its main function is to store fat. Fat is important to our body as it helps up keep warm and provide protection for our bones and organs.

The number of skin layers that exists depends on how you count them the human body have three main layers of skin—the epidermis, dermis, and hypodermis (subcutaneous tissue) in these layers are additional layers if we count the layers within the layers, the skin has eight or even 10 layers Skin is the largest organ in the body and is quite complex Its primary function is to act as a barrier against disease-causing pathogens (germs) and hostile environments it also helps regulate body temperature and gathers sensory information from your environment
The Epidermis top layer
The epidermis is the outermost skin layer its thickness depends on where it is on the body it’s thinnest on the eyelids (roughly half a millimeter) and thickest on your palms and soles 1.5 millimeters.
The Dermis middle layer
The dermis is the middle layer of the skin. It contains connective tissue, capillaries, nerve endings, and hair follicles it also contains different glands, including sebaceous glands that produce sebum (a body oil) and apocrine glands that produce sweat.
Hypodermis bottom layer
The innermost layer of the skin is the hypodermis. Also known as subcutaneous tissue, the majority of your body fat is stored in the subcutaneous layer. It insulates you against changing temperatures and protects your muscles and internal organs from impacts and falls ,in medical shorthand subcutaneous is abbreviated SQ , an SQ injection is delivered to the subcutaneous layer.-

You included some great examples, Carlos!

Awesome to think about that the skin can be almost a sense on itself, like identifying and regulating temperatures

The skin is the largest organ in the body and has three main layers: the epidermis, dermis, and subcutaneous tissue, all with different functions and vital for keeping us healthy.
The top layer, the epidermis, shields us from things like germs, sun rays, and chemicals. It’s made up of many cell layers, with the outermost layer made of dead cells called keratinocytes. New cells are always made in the deeper layers and replace the old ones. The epidermis also has melanocytes, which make melanin to protect our skin from the sun and give it color. There are also Langerhans cells here, part of our immune system, which help fight off germs.
Below the epidermis is the dermis, made of connective tissue, blood vessels, nerves, and things like hair follicles and sweat glands. It gives our skin its shape and flexibility. It has receptors that help us feel touch, pressure, pain, and temperature changes. Blood vessels in the dermis help control body temperature by opening up or tightening up to let heat in or out. It also has immune cells to fight infections and help heal wounds.
The deepest layer is the subcutaneous tissue, or hypodermis, made of fat and connective tissue. This layer stores fat as energy. It insulates the body from heat and cold and provides protective padding to the bones and muscles underneath. It also has blood vessels and nerves that connect to the dermis and epidermis, helping all the skin layers work together.

One of the most interesting things about our skin to me is the fact of how flexible it is, not only does it move with your body but it adapts to many different situations we might go through
