The second remedy is that the glands under the skin secrete sweat onto the surface of the skin in order to increase heat loss by evaporation if the body is too hot. And thirdly the capillaries near the surface can open when the body needs to cool off and close when it needs to conserve heat (The Integumentary System, 2008).
The skin plays a very important role in regards to a person's sense of touch. The nervous system depends on neurons that are embedded in the skin to sense what's happening in the outside world. It processes input from the senses and initiates actions based on those inputs. The integumentary system also contributes to a number of different physiological processes; especially those that are involved in the regulation of the body's internal environment so that it can remain stable (The Integumentary System, 2008).
As people get older many changes take place within the integumentary system. The epidermis gets thinner as basal cells divide less over time. The dermis also thins and its elasticity decreases. This causes the skin to become weak and start to sag and wrinkle. Melanocytes reduce their production of melanin which causes the skin to become pale and hair to turn white. Sebaceous glands also decrease their production of sebum which causes the skin to become dry. The blood flow to the skin is reduced and body temperature is not as well regulated as well. Lastly, the skin begins to take longer to repair itself after injury (The Integumentary System, 2009).
Even though there is no way to avoid the aging process of the skin, there are ways to reduce the effects on it. The loss of elasticity in the skin can be increased sunlight. The skin should always be protected from the Sun by the use of sunscreens and protective clothing. Sunburns are not good for the skin and should be avoided. This also helps to reduce the risk of skin cancer as well. There are many things that contribute to keeping the integumentary system operating at its best. These include having proper nutrition, drinking healthy amounts of quality water, getting adequate rest, exercising regularly and reducing stress. Although hair loss and graying are both controlled by genetics,...
Integumentary system is comprised of the skin and skin derivatives including hair, nails, glands and receptors. Skin, glands and receptors have many important functions that will be described in this paper (The integumentary system (skin)): Protects the body's internal living tissues and organs Protects against invasion by infectious organisms Protects the body from dehydration Acts as a receptor for touch, pressure, pain, heat and cold Protects the body against abrupt changes in temperature Stores water, fat,
Physiology Body Systems Involved in Eating a Snack The first thing I do when eating a snack is to prepare it. In this case, I reach into the cabinet above me and grab a bag of potato chips. I read the label and make sure they are plain chips, because I do not like flavored chips. When I am satisfied they are the type of chip I like, I break open the
The efferent division of the peripheral nervous system carries out the motor commands that are sent from the central nervous system. These commands or signals are then sent directly through the nerve fibers of the peripheral nervous system to the target organs where they will then be signaled to perform the desired action (Martini, Nath, & Bartholomew, 380). The peripheral nervous system can be further broken down as being a
However, all muscles are ultimately controlled by the central nervous system. Because the muscles are attached to the skeleton, all skeletal movements can be traced back to the central nervous system. The integumentary system is one of the body's primary interfaces with the outside world. Together with the sensory system, the integumentary system interact with the central nervous system by communicating its inputs. 3. Homeostasis is the body's state of
Nervous System: In order to achieve its function, the nervous system is divided into two major parts i.e. The Central Nervous System (CNS) and Peripheral Nervous System (PNS). The central nervous system is basically made up of the brain and spinal cord and has the main function of receiving information from the body and sending out instructions. While the brain is protected by the skull, the spinal cord is guarded
Lymphatic system is a sub-system of the circulatory system. It contains a network of nodes, or vessels and filters, which remove toxins from the body. The role of the lymphatic system in the homeostasis of the body is that it serves as the primary drainage for all of the body's other systems, removing all toxins and excess fluids. It is a major defense against disease and also helps carry nutrients
