Though many people joke that years of college drinking impacted their liver, in actuality, it is years of poor diet and exercise that really impede the liver’s ability to function. According to “Nutritional Healing,” the liver is responsible for metabolizing fat, thyroid function and removing toxic substances from the body. Author Phyllis Balch explains that overeating, a poor diet, toxins and drugs can wreak havoc on the liver. Cleansing this vital organ is possible, however, with a good detox diet.

There are parts of the human ear that still baffle scientists–tiny intricate parts all working together to provide us with hearing and balance.

It is never easy to tell a child she has an illness or that something is “wrong” with her. You have to deliver the news in a way that stresses the seriousness of the situation, but does not make her feel ashamed or think that she is somehow defective.

There are effective ways to tell a child she has ADHD. Use the conversation to put things in a light that is hopeful and affirming.

Major depression can occur as a single episode or repeat throughout a person’s lifetime, according to the National Institute of Mental Health. The symptoms of major depression can differ between men and women, and one person’s irritability, low mood and inability to function in everyday life can place enormous strain on a marriage. Living with a depressed spouse is a two-fold obstacle of doing what you can to help your depressed partner while also maintaining your own well-being.

Living with a spouse with depression is a difficult journey. Depression is among the most common emotional disorders, and it could destroy a marriage. Ideally, marriages are 50/50, but when a spouse is experiencing a bout of chronic depression, you will more than likely carry the load. Resentment and anger can easily develop from there. Creating a system of support and having the attitude that you are committed to your marriage is a strong foundation from which to start.

If you are a winemaker, and you want to produce a wine that has the right level of acidity—so it has a longer shelf life—you need to know how to test for tartaric acid. Knowing this important procedure will help you to add just the right amount of sodium hydroxide during your wine-making process.

The skeletal system provides the framework and support for our bodies’ muscles, tissues, nerves and skin. It also protects vital organs, allows movement, stores minerals and, through marrow, produces blood cells.

Assessing range of motion is measuring the movement of the joints in the body during flexion or extension. Assessment is done in order to gauge how functional the movement in a joint is. Injuries such as breaks or spinal cord damage, diseases like arthritis, infections and severe burns are examples of conditions that can limit range of motion. A physician, physical therapist or occupational therapist may take this measurement at the beginning of treatment and as treatment proceeds to see if there is any improvement or decreased movement in the joint. This will help to gauge what type of treatment is needed or if adjustments need to be made to the existing treatment.

Oxygen can be prescribed for home use by a physician. There are three different oxygen delivery systems suitable for home use–compressed oxygen tanks, oxygen concentrators and liquid oxygen tank. The oxygen concentrator system needs electricity to work. It makes oxygen by drawing air from the environment, then extracting the oxygen from it and storing this oxygen for delivery to an individual through a nasal cannula or oxygen mask. The air intake filter allows air to flow into the oxygen concentrator and needs to be cleaned regularly for the equipment to work properly.
