blotchy skin

While online searching for a solution to repair my damaged summer skin, I came across the term "blotchy skin".  I wanted to understand what the root cause and treaments of this disease are.  After hours of research I learned that blotchy skin was caused by exposure to too much sun, ance and hormone imbalance. There are two different kinds of blotchy: skin discoloration and dry skin.  According to the blotchy skin article that was published on Realself website, "Red blotchy skin and brown or white blotchy skin are skin discolorations that create uneven skin pigmentation, while blotchy dry skin or itchy skin results in an uneven skin texture and tone."   Some tips and products to treat this disease are aslo provided on this website.  To prevent this disease, one must protect skin again sun and keeping skin moisturizer.

Many websites provide information and advertise their products for treating bloctchy skin problems.  So which is the best product? I don't have any answer to this question because each skin type requires a special treament or type of care.
Below are some pictures of blotchy skin redness discoloration

Healing of the wounds or injury

I am discussing this topic because it was one of many the questions on the first Human Anatomy and Physiology exam.  Due to the limited time, I couldn't provide a correct answer to the question, and it stuck in my head.  I decided to explain it here.

During inflammation, blood vessels dilate and become more permeable causing, tissues to become red and swollen. The body is responds to the injuryin various ways.  A superficial cut is simply filled by reproducing epithelia cells. In contract, deeper cuts are first closed off by clots, and then covered by scabs and filled in by fibroblasts making connective tissue.  Blood vessels extend into the wound, it rplaced and the scab falls off.  Larger wounds leave scars and require longer of healing times.

Skin tissue

Have you ever wondered why your skin color different 's from your friends or family? A few years ago I realized that my skin was much darker than my siblings.  I did not understand why until today, when I read about human skin in chapter 6, of my Human Anatomy and Physiology book.  There I learned that  skin color results from a combination of genetic, enviromental, and physiological factors. Genetic differences in skin color are caused by differing amounts of melanin in the skin and by differences in the size of melanin granules. Exposure to sunlight causes darkening of the skin because melanin production increases because it circulatin within dermal blood vessels affects skin color. Is there any solution to repair my damage skin? I'm not sure. I have always liked to work in the garden so my skin will probly always be darker than my sisters.

What is the definition of skin?
   Skin is a large organ responsible for maintaing homestasis through temperature regulation, protection of underlying tissue, retartdation of water loss, housing sensory receptors, synthesizing certain chemicals and excreting wastes.  It consists of an outer epidermis and an inner dermis connected to underlying tissue by the subcutanceous layer.

I understand the definition of skin but still don't have any clue of how to improve my skin.  May be more study will help me.

Chronic lung disease

I have never heard of chronic lung disease until I read the information of Atrial Fibrillation, which avaliable and published at Heart Center of The Rockies Poudre Valley Health System office.  It claimed that chronic lung disease is one of the root cause of Atrial Fibrillation.  I was courteously about this topic and decided to learn more on it.  Especially, what the root causes, symptom and treatments of this disease are. How to prevent it.  Can a patient survive? if so what are chances of this happen?

Many papers were published and discussed on this topic, therefore, I would only provide a summary of this disease.  Causes are: damaged airways that prevent the healthy exchange of oxygen and carbon dioxide in the lungs, lung injuried, the tissues inside the lungs become inflamed and can break down to form a scar. this scar would make difficulty breathing and require more oxygen.  Symptom are shortness of breath during physical activities and chronic cough for three months if the patitent is smoke. These symptoms were not showed until significant lung damaged and unable to reversed.  Sadly, there is no cure for this disease.  However, there are few medications could help patient breathing better. Steps to prevent are: avoid breathing toxic fumes from chemicals, solvents, and paint, wear protection mask when you work with chemical, and don't smoke. I could not find any information on survive of this disease. Picture of lung that helped or gave me a better understand of the disease.

Atrial Fibrillation

What is Atrial Fibrillation?
  It defines as a heart rhythm disorder. The electrical impulses that control contraction of the heart's left and right atriums become rapid, fast and irregularly. This would make difficult for the chambers or atriums to pump out all the blood, which contains in the heart.  It may cause stroke or heart attack due to blood clots.  Below is the heart section through the middle.



Sign and symptom of Atrial Fibrillation are:
- Racing of heartbeat, dizziness, fainting, shortness of breath, faitgue and chest discomfort.

What is the root cause of Atrial Fibrillation?
At the moment, I don't have a good answer to this question.  However, I have been observing my uncle who is recently diagnose with this disease, and found that he always feel over-tired, lack of energy and discomfort in the lung.  Will the lung cause this disease? if so how and why?
