Skin Functions, Framework and Relationship with the Body

Section D

Describe the main function of the skin, its structure and the relationship between your skin, circulatory and nervous system

  1. Draw a label diagram of your skin and describe its structures and key element parts

(See diagram fastened)

The skin is the largest organ in the human body. It possesses three layers; the skin, dermis and subcutaneous layer.

The epidermis

“The upper or outer level of the two key layers of cells that make up the skin. The skin is mainly made up of flat, scale-like cells called squamous cells. These cells develop melanin, which gives your skin its colour” (MedicineNet.com 2016).

The epidermis is the outmost layer of your skin, the skin we are able to see. This level differs in thickness; it is thinner on the eyelids and nipples than it is on the soles of ft and palms of hands. This layer has water resistant properties and defends us from cuts and accidental injuries. The epidermis provides the pigment melanin gives us the skin we have tone.

The dermis

“Lying underneath the epidermis-the most superficial coating of our skin-is certainly the dermis. The dermis can be a hardcore layer of pores and skin.” (Boundless.com N/D).

The dermis may be the layer under the epidermis; this level is attached to the blood and nerve source. It contains sweat glands and hair roots and connective tissues.

The subcutaneous layer

“The bottom layer of skin is the subcutaneous fat layer.” (American Academy of Dermatology 2016).

The subcutaneous layer is made up of fatty cells or bundles of adipose cells. This layer is accountable for retaining heat within the body. The smaller these bundles of adipose tissue are, the less over weight it’s likely you’ll be.

Functions of the skin

  • Protection: The skin really helps to protect us from items such as for example dehydration, harmful microorganisms, bacteria and UV rays from the sun.
  • Absorption: The skin can absorb chemicals that your body need such as oxygen and nitrogen. Some prescription drugs/ointments may be put on and absorbed by your skin for muscle pain, for instance, deep high temperature or oriental tiger balm.
  • Sensation: Receptors in the skin allow us to touch and feel soreness, heat and cold.
  • Temperature Regulation: Sweating starts at around 37°C. The sweat involves the surface of the skin and evaporates, creating the body to lessen the heat, together with this, the hair on our arms lay down to allow the heat to escape. When we are cold the contrary happens: the hairs stand up and goose bumps web form to trap any heat in the body so that you can warm us up again.
  • Immunity: The skin and the immune system work together to make the immune to microorganisms and bacteria.
  • Movement and development: The skin area is stretchy as a result of its elastic properties which allows the covering of the complete body and the motion of the individual.
  • Excretion: Your skin allows materials such as urea, excess water and ammonia from the skin. By-products that aren’t wanted or required by your skin are released through sweat glands in the kind of sweat. Excretion is an important function to notice about the skin (New Health Advisor 2014).
  • Vitamin development: Upon exposure to ultraviolet light (sunlight), the skin produces vitamin D. That is important for the expansion and strengthening of bone (Curran 2016).
  1. Give details of the relationship between your skin, circulatory program and the nervous system.

The skin

The skin may be the largest organ in your body and is wide spread through the entire whole body. The skin absorbs essential nutrients and natural oils through the pores and this provides moisture to the skin. The skin consists of three layers: The dermis, epidermis and subcutaneous layer.

The dermis may be the layer under the epidermis; this level is mounted on the bloodstream and nerve source. It consists of sweat glands and hair follicles and connective tissues.

The epidermis is the outmost layer of your skin, the skin we can see. This coating differs in thickness; it is slimmer on the eyelids and nipples than it is on the soles of foot and palms of hands. This layer has water-resistant properties and protects us from cuts and accidental injuries. The epidermis contains the pigment melanin gives us the skin we have tone.

The subcutaneous layer comprises of fatty tissues or bundles of adipose tissue. This layer is in charge of retaining heat in your body. Small these bundles of adipose cells are, the less overweight you are likely to be.

Functions of the skin

  • Protection: The skin really helps to protect us from items such as dehydration, harmful microorganisms, bacterias and UV rays from sunlight.
  • Absorption: Your skin can absorb substances that the body need such as oxygen and nitrogen. Some medicines/ointments may be applied to and absorbed by the skin for muscle pain, for instance, deep high temperature or oriental tiger balm.
  • Sensation: Receptors in the skin allow us to contact and feel soreness, heat and cold.
  • Temperature Regulation: Sweating begins at around 37°C. The sweat comes to the top of skin and evaporates, triggering the body to lessen the heat, in addition to this, the wild hair on our arms lie down to allow the heat to escape. When we are cold the opposite happens: the hairs operate and goose bumps form to trap any heat in the body in order to warm us up once again.
  • Immunity: The skin and the immune system work together to help make the immune to microorganisms and bacterias.
  • Movement and progress: The skin area is stretchy because of its elastic properties which allows the covering of the whole body and the movements of the individual.
  • Excretion: Your skin allows materials such as urea, excess water and ammonia out of your skin. By-products that are not wanted or required by your skin are unveiled through sweat glands in the form of sweat. Excretion is a significant function to notice about the skin (New Health Advisor 2014).
  • Vitamin creation: Upon contact with ultraviolet light (sunlight), the skin produces vitamin D. That is important for the progress and strengthening of bone (Curran 2016).

The nervous system

The nervous system includes the brain, spinal-cord and opinion essay outline all of the nerves that hook up to these organs to the rest of the human body. The cells in the anxious system are known as neurons plus they transmit impulses along the nerves to carry messages between the brain and your body via the spinal-cord. When the brain receives the info, it processes it before sending out the demands for your body. Neurons contain a extended axon which is protects by myelin sheath in addition to tiny branches called dendrons which branch out into more compact parts known as dendrites ( BBC 2017).

Motor neurone. At one end there is a nucleus surrounded by cytoplasm and dendrite.  All enclosed by a cell membrane.  There is a long tail holding the Axon which connects with the nerve endings.(BBC 2017).

The autonomic nervous system regulates somebody processes like blood circulation pressure and breathing which job without the effort from the individual. The somatic system consists of the nerves that are connected to the receptors in your skin. This is the system that protects us form getting burnt when positioning or hand on a hot area as the brain sends signals via the spinal-cord to tell us to lift the hands off the top.

The circulatory system

The circulatory system contains the heart, bloodstream containing oxygen and skin tightening and and the arteries including veins, arteries and capillaries. These blood vessels have muscles inside their walls in which the bloodstream flows through and these muscle tissues are managed by the nervous system. The circulatory program is in charge of providing blood, hormones, nutrients and oxygen to all the cells in the body. This technique also fights disease through white blood cells and antibodies and assist in the clotting of blood through platelets which shape scabs on the examples of compare and contrast essay surface of the skin area when cut and exposed to oxygen.

The relationship between the skin, nervous system and circulatory system

The skin, nervous system and circulatory system work together as a way to ensure your body is functioning the way it will. The somatic nervous system works together with the central nervous system to safeguard the skin. It can this by telling us to lift our palm off a hot area in order to avoid burning ourselves. The nervous system and circulatory program are linked by the lymphatic program and interact to maintain blood circulation pressure and regulation of the center. The nervous program “tells” the circulatory system to pump blood vessels around your body. The nervous program and circulatory system needs to function correctly and interact to ensure the rest of the body is functioning properly. The nervous program controls all functions of your body. The circulatory program provides blood circulation and regulates body’s temperature. The skin works together with it to regulate the body temperature. When too popular the arteries dilate, the hairs lay down and we sweat to permit excess heat to flee the body. When we are too wintry the hairs stand up and goose bumps type to trap any heat in your body. If blood flow is fixed, your skin becomes pale. If among these devices became damaged at all, the body could have abnormal functioning (Curran 2017).
