Everyone at some point in their lives has had some sort of wound. Wounds usually come in all different shapes and sizes: from a papercut to a gushing leg wound. And let us not forget that wounds can also happen internally like a sprained ankle or a concussion. What never goes through are heads is: How do our wounds heal and repair themselves? Understanding the process on how wounds repair themselves can be a little overwhelming so I’ll explain it by telling a little story. Stephen Curry, one of today's NBA’s greatest players, loves the game of basketball. While Curry faced his rivals, the Oklahoma CIty Thunder, he was crossed over by the MVP Russell Westbrook. In result of that, Stephen Curry was taken out of the game because of a sprained …show more content…
Inflammation is the first step that every wound takes to repair and heal itself. The purpose of inflammation is stop the bleeding and not let the injury get worse. When inflammation occurs, the healthy cells isolate themselves so the damaged cells can get cleanup by phagocytes. While that is occurring mast cells are activated to release histamine which causes vasodilation in the affected area. Vasodilation is when blood vessels expand in the wounded area. Vasodilation causes red blood cells, water, heat, and clotting proteins to be leaked out in the affected area. The redness and the heat from the wound is coming from the leaked red blood cells. Swelling is caused from the leaked water from vasodilation. The pain is also caused by the water that leaks out during vasodilation because the H2O presses against your nerves. Inflammation causes an increase of nutrients(for ATP), oxygen(for ATP), white blood cells(fight off bacteria), blood-clotting proteins, …show more content…
The second step to repair a wound is the organization process. The purpose of the organization process is to restore the blood supply in the wounded area. The organization process starts with the stratum basale skin layer growing into the wounded area so there could still be a live blood supply. In Curry’s case, new blood capillaries would be produced by the help of uninjured capillaries because his wound was internal. Afterwards a granulation tissue, a delicate layer made up of capillary blood vessels and collagen, covers up the blood clotted area. The granulation tissue is important because it helps fight off bacteria in the wounded area. Then fibroblasts produce collagen fibers to connect the wounded area together, which could possibly be scar tissue. The last step in the organization process is macrophages eat up the original blood clot and any other dead cells in the
What is the physiologic mechanism causing the wound to become red, hot, swollen, and painful?How is this different than the inflammatory response that might occur in an internal organ?
Inflammation: the response to injured tissue that stops bleeding and causes swelling and warmth as the tissue prepares to repair itself
Everyone knows that Michael Jordan is the greatest basketball player of all time, and the “Flu Game” is a perfect example as to why Jordan is. He had to battle the flu in a very important playoff game. Michael Jordan had so much ambition and aptitude in him that he was able to battle through it and make the game winning bucket. Jordan is a prime example of a kid working hard to achieve his life goals. Michael Jordan pushed himself to greater heights and this proved to people that he was such a great player.
Most scalp wound is caused by blunt hit. However, it will bleed a lot although it is a minor wound since there are so many blood capillaries in the area. Normally to treat this injury, we just need to put a direct pressure on the wound with sterile dressing material until the bleeding stoped. And tie the cloth into place with a triangular bandage if continued pressure is needed. Carefully assess whether stitches are needed. If decided to treat at home, be sure the wound is free of dirt and debris. Clean with clean water , then dry the wound and surrounding hair. It usually recover well. Make sure there is no wood or gravel in the wound. To avoid more serious complication, pay a visit to a doctor for double
The symptoms experienced by Carlton are in the group of the cardinal signs of inflammation that have been identified for centuries (Grossman & Porth, 2014). Carlton’s wound is in the first stage, the inflammatory phase, of acute inflammation, which is the beginning of a complex, regulated, and critical process of immunologic events (Rosique, Rosique, & Farina Junior, 2015). There are two main types of stimuli that cause this kind of biological and immunological reaction: physical injury and microbial infection (Qian et al., 2016).
These types of injuries could take upwards to eighteen months to return to playing condition, and in this time an athlete will often fall behind in the sport that they love. This often causes the athlete to quit the sport they once loved because they can no longer truly compete amongst their peers. I know that there has to be a way to accelerate this process of recovery and get those athletes back on the field. This is where my passion for orthopaedics
Have you thought of all the things NBA players have gone through to get where they are? I choose to talk about the top three players in the NBA. I choose this topic because I pay attention to all the things that make up some of the best basketball players today. I wanted to know more about the players history. Even I don’t know everything about their past.
Sepsis is defined as an exaggerated, overwhelming and uncontrolled systemic inflammatory response to an initially localised infection or tissue injury, which may lead to severe sepsis and septic shock if left untreated (Daniels, 2009; Robson & Daniels, 2013; Dellinger et al, 2013; Perman, Goyal & Gaieski, 2012; Vanzant & Schmelzer, 2011). Septic shock can be classified by acute circulatory failure as a result of massive vasodilation, increased capillary permeability and decreased vascular resistance in the body, causing refractory hypotension despite adequate fluid resuscitation. This leads to irreversible tissue ischaemia, end organ failure and ultimately, death (McClelland & Moxon, 2014; Sagy, Al-Qaqaa & Kim, 2013, Dellinger et al, 2013).
The inflammatory response is a nonspecific response to cellular injury and bacterial invasion. Inflammation is the primary defense in early gingivitis. Biofilm can initiate an inflammatory response if it is left undisturbed for as little as seventy two hours. Redness and swelling are two of the cardinal signs of inflammation and can be observed clinically in gingivitis. Histamine is released by mast cells and responsible for the redness and swelling of tissues. Histamine causes both an increase in vascularity and permeability of blood vessels at the site of injury. Swelling may occur in response to the accumulation of fluid at a specific site. The inflammatory response includes cellular components of the immune system polymorphonuclear leukocytes and macrophages. Polymorphonuclear leukocytes are crucial to the cellular immune response. Polyporphonuclear leukocytes are the first cells that arrive at an inflammatory site. Polymorphonuclear leukocytes arrive at the site via chemotaxis, and begin to phagocytize bacteria. As the disease continues and the inflammatory reaction is not strong enough to subside the bacterial infection the immune response is further
Sports are often identified to have positive influences on many individuals. The sports industry is growing worldwide, especially the basketball industry, which is regarded in second place behind football. The global prevalence of basketball is unquestionable, especially among the young. Basketball is a dynamic team sport that involves a pattern of alternating, active, and skilled movement activities. There are compound demands that require a mixture of individual skills, team plays, strategies, and motivational aspects.
Inflammation which is part of the innate immune system is a process by which the body reacts to injury protecting it from infection and foreign substances with the help of the body’s white blood cells “Inflammation can be defined as the body’s local vascular and cellular response to injury caused by factors that invade and injure the body from the outside (exogenous factors) or factors within the body that result in cellular or tissue injury (endogenous) factors” (Battle, 2009, P 238). Factors such as bacteria, viruses, burns, frostbite, chemical irritants, immune reactions and physical injury are examples of factors that can cause inflammation through different mechanisms. It is a protective mechanism with rapid response that neutralizes or destroys agents that causes injury and creates a barrier that limit the injury and prevents its spread to normal tissues (Battle, 2009). Also, it has elements that removes debris and heals the wound generated by the injury. It can be divided into acute and chronic inflammation.
Our approach in managing wounds was far from being optimal in our own setting. After having read the article of Sibbald et al (1) and assisting to presentations during the first residential week-end, our approach at St. Mary 's Hospital Center 's Family Medicine Clinic must change. We were not classifying wounds as healable, maintenance or non-healable. We were always considering the wounds in our practice as healable despite considering the system 's restraints or the patients ' preferences. In the following lines, I will define and summarize the methods one should use in order to initial management of wounds and how to integrate it better to our site. The first goal we need to set is to determine its ability to heal. In order to ascertain if a wound is healable, maintenance or a non-healable wound.
(A)Wound healing is a biological process occurring in the human body. In this lecture we had discussed about both acute and chronic wounds. An acute wound is an injury to the skin that occurs suddenly rather than over time. It heals at a predictable and expected rate according to the normal wound healing process. The chronic wounds do not heal in an orderly set of stages and in a predictable amount of time the way most wounds do.
Research proves a strong connection between psychological stress and health, including poor surgical results, and a decrease in the immune system functioning. This is vital regarding wound healing especially on the skin because the skin is the largest organ of the human body and has many responsibilities including regulating temperature, vitamin D production, and protection. With the skin being such a vital organ, timely wound healing is extremely important. Psychological stress has been shown to negatively impact wound healing, both directly and indirectly. It has been found that psychological stress can spike the levels of some hormones in the blood, which directly impacts the wound healing. These hormones can slow the delivery of certain compounds like cytokines to the location of the injury to start the healing process. This will ultimately slow the healing process. It also indirectly impacts wound healing through people who are experiencing anxiety, who could possibly have trouble sleeping at night. This can further exaggerate the weakening of the immune system, which could lead to a wound infection when the body can’t fight off damaging bacteria and
The white blood cells destroy any unfamiliar pathogens in the bloodstream and can cause inflammation. Therefore, the inflammation causes a surplus of white blood cells to clot the wound for healing.
