Recommended: Five physiological responses to injury
Although we might not all agree on whoever or whatever created the human body, I think we can all agree it is an amazing, self-functioning machine. The ability of the body to maintain a healthy status quo and to heal itself without input is unlike any man made machine in existence. However, with today’s society wanting more and at an ever accelerating rate, the incredible inventions of doctors, engineers and scientists have that work in conjunction with the body to heal is truly amazing. Despite the body’s talent to heal subconsciously, it turns out there is many ways we can affect the process with our current health, both positive and negatively. The human body has programmed ways to recoup and revive damaged cells but in an ever changing world there are many things we can do externally and internally to affect the body’s already amazing process.
When a child falls and scraps their knee or gets a cut in his or her hand, their first conscious instinct is to cry and run to the nearest parent, however their body’s first instinct is to contain and coagulate the blood. Even as adults, people never have to sit there after getting a paper cut and think, “Ok body, coagulate!” The body jumps into action automatically and without any prompting from our conscious mind. In a typical wound, the body goes through four stages; hemostasis, inflammation, proliferation, and remodeling. (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2903966/). In hemostasis, the skin constricts and a clot forms. Once the cut has coagulated, the inflammation cells enter the wound and remove invading microbes and debris. The proliferation phase overlaps with the inflammation phase to rebuild collagen and granulation tissue so a scab will appear. The ...

...dmother, everyone wants to get the most of their life and at the best quality. There is so many ways to enjoy life and being held back by any preventable health issue such as a chronic wound would stop people from living up to their potential. Now I know you must be thinking that it is a simple wound that we are discussing here but it is more than that. Learning about and appreciating our body helps us to live a better, more fulfilling life and I don’t know anyone who doesn’t want that.

Carlton suffered an acute tissue injury on his foot after stepping on a sharp edge shell, which disrupted the layers of the skin. Immediately after an injury occurs, an inflammatory response begins, which serves to control and eliminate altered tissue/cells, microorganism, and antigens. This takes place in two phases. 1) The vascular phase, in which small vessels(arterioles, venules) at the site of injury undergo changes. Beginning, with
Ross defines and differentiates between the terms healing and curing. She recognizes the fact that healing and curing are very intertwined and it can be hard to distinguish between the two terms. There are differences between the definitions in scholarly and general settings. She references an ethnographic study of healing versus curing conducted by anthropologists Andrew Strathern and Pamela Stewart in 1999 with native groups in New Guinea. The results of the study looked at how energy used by the different types of tribal healers to either cure or heal a patient. Eastern medicine focuses on how energy interacts with the healing process in connection within the mind. Whereas Western medicine is focused on the mind and the body separately. The practice is considered a holistic approach to finding cures. According to Ross (2013), healing is more a therapeutic process targeting the whole body and specific illness including emotional, mental, and social aspects in the treatment. The act of curing is a pragmatic approach that focuses on removing the problem all together. The life experiences of a person playing into how well certain treatments will heal or cure what is ailing them. These aspects can not be defined with textbook definitions. The interaction that the healing process has with energy is a variable in the success rate. Uncontrolled emotions can have a greater impact on the inside the body than a person can realize. The exploration of energy interaction within the body can be used for greater analysis of health care systems. (21-22). Are Western healthcare facilities purposely “curing” patients just so that they return are few years later? Is Western Medicine built upon a negative feedback loop? The terminolo...
Through the continuing studies focused on regeneration and stem cells, scientists can try to see how manipulate totipotent cells found in humans to regenerate into any cell needed throughout the body (Wagner et al., 2012). Humans will benefit from advances in regeneration when faced with degenerative diseases that affect the muscular system or major organs necessary for life. Regeneration can help rebuild organs or muscles damaged by infection or disease and change medicine and human health (Salvetti et al., 2009).
Inflammation: the response to injured tissue that stops bleeding and causes swelling and warmth as the tissue prepares to repair itself
A pressure ulcer is an area of skin with unrelieved pressure resulting in ischemia, cell death, and necrotic tissue. The constant external pressure or rubbing that exceeds the arterial capillary pressure (32mmHg) and impairs local normal blood flow to tissue for an extended period of time, results in pressure ulcer (Smeltzer et. Al., 2013). According to National Pressure Ulcer Advisory Panel, 2014, pressure ulcers are a major burden to the society, as it approaches $11billion annually, with a cost range from $500 to $70,000 per individual pressure ulcer. It is a significant healthcare problem despite considerable investment in education, training, and prevention equipment. This paper includes two different studies to link cause-effect
Belvoir Media Group (2010) realised an article claiming that although pressure on the skin is the focal cause of decubitus ulcers, other factors frequently fund this problem. These factors include; shearing and friction causing the skin to stretch and blood vessels to curve which results in impair blood circulation, Moisture, circulatory problems, age, and people with poor nutrition. It further claims that ulcers can be categorised in different stages (stage 1; being the initial stage, and stage 4; being the most severe), and treatments for ulcers include distinct dressings to be applied to promote healing. Cooper (2013) likewise clarifies that many different factors contributing to the progress of ulcers in supplement to pressure such as moisture, shear and friction. She additionally goes on to say that hydrocolloid dressings do not relieve pressure, nonetheless do reduce friction and shearing of the wound.
Since the dawn of man, humans have dreaded the suffering caused by injuries and disease. For our benefit, we have enhanced the practices of Medicine and its techniques, but before such ideas existed; the risk of recovery was extremely traumatic and at times fatal. We have abandoned several of the medical procedures used in ancient times since intrepid scientists and physicians sought methods. Although medicine was not always a science, instead it was magic, thus god were trusted for a few techniques more than actual logic. Therefore, the history of medicine has been disturbing and dangerous, but a good number of its practices today used in a more modern way, is quite beneficial to humanity.
Whenever an injury cannot be avoided, however, it activates a series of mechanisms to repair the organism. Evidence of these systems comes from blood platelets that clot wounds to prevent bleeding out.
The two videos that I like the most from this class was the ted talk name “America’s native prisoners of war” by Aaron Huey, and the documentary “When Your Hands are tied” by Mia Boccella and Marley Shebala. These two videos brought my attention because in the first video which is the ted talk the author of the video is an outsider of the society that he is trying to represent he did not go through the experience that the native people that he is trying to defend went through. In the documentary when your hands are tied this is a little bit more personal I think because this is a documentary where people from the tribe and people that went through all this obstacles are trying to heal themselves.

The normal wound healing process mainly consists of four main stages being haemostasis, inflammation, proliferation or new tissue formation, and tissue remodeling or resolution. For a wound to heal well the above mentioned stages should occur in a sequential and orderly manner. Disturbances, abnormalities and delays in any of the above stages may lead to impaired healing or even chronic wounds. In adults, this process of normal healing takes place in the following steps (1)rapid haemostasis (2)appropriate inflammation (3)mesenchymal cell differentiation, proliferation, and migration to the wound site (4)suitable angiogenesis (5)prompt re-epithelialization and (6) proper synthesis, cross-linking, and alignment of collagen to provide strength to the healing tissue.

Once the vascular component has been assessed, we get a clear idea of the main limiting organic factor in wound healing. We can then build on this information by assessing the patient 's cofactors in healing. This step is essential in order to maximize the vascular network the patient possesses. Those cofactors are:
The Health Triangle includes the aspects of physical, mental, emotional, and social health. As a teenager, I have strengths and weaknesses that contribute to all three aspects of my health. There is always was for me to improve my health as I point out where that improvement in needed.
These procedures hold infinite possibilities in the practice of healing the sick. Of all of the procedures mentioned, cloning is the only method that has been given any amount of serious research. Cloning could do away with the need for organ transplants. Instead of a transplant, a new organ could be cloned, thus removing any chance that the body might reject the organs. Nano-robotics can be used to fight off foreign infections and repair internal wounds.
