Oxygen is an essential element for the human body to function normally. When you breathe in, the oxygen travels through your lungs and into the blood stream, where red blood cells pick it up to distribute it throughout the body. Poor air intake,...
Your body needs oxygen to produce the energy needed to function normally. The oxygen you breathe in goes through tiny air sacs in your lungs and into the blood stream, where red blood cells pick it up and carry it throughout the body. This system...
Because your cells need oxygen to live, it is important to keep your oxygen at a level to which your body can function properly. Because the body is unable to store oxygen, it must be constantly supplied throughout blood cells when levels are low....
The brain only occupies roughly 2 percent of total body weight, and uses 20 percent of the overall oxygen supply in the body, according to Barbara Carlson, RN, Ph.D. and colleagues in May 2008 in the "Journal of the American Geriatric Society."...
Inherited genetic diseases are passed on by either one parent--as in the case of autosomal dominant diseases, in which only one copy of the gene need be present for a person to have a disorder--or by both parents. In recessive genetic diseases,...
Because breathing is largely an unconscious process, it's only when breathing becomes difficult that a person begins to take notice. The earth's atmosphere is 21 percent oxygen, which is enough to support human life until problems arise. When...
Episodic headaches affect the overwhelming majority of the population. While inconvenient, episodic headaches are rarely consequential from a medical or personal perspective. In contrast, chronic headaches may substantially interfere with daily...
Meconium aspiration is a common complication of childbirth in a newborn. Meconium is the first stool passed by a newborn; it's dark green, very sticky and thick. If a baby is stressed in utero, even for a short time, meconium may be passed into...

The body needs an adequate amount of oxygen in order to function properly. There are many diseases and situations that can affect the ability of the heart and lungs to keep up with the demand. If the levels of oxygen in the blood get too low, a...
Aerobic exercise can alter the number of red blood cells in several ways. Red blood cells carry oxygen and carbon dioxide through the bloodstream. In general, endurance training increases the number of red blood cells. However, in some cases,...
Anemia is a disorder characterized by low oxygen levels in the blood. Symptoms of anemia include fatigue, weakness, and paleness. One cause of anemia is iron deficiency. Iron is necessary for oxygen to bind to hemoglobin, the active component of...
Air ionizers are one of several home appliances designed to combat poor air quality. Though manufacturers often place numerous health claims on the labels of air ionizers, only a few of these claims are backed by actual science. Combined with a...
Propofol is also known as Diprivan and belongs to a class of drugs known as general anesthetics. The National Institutes of Health states that propofol induces and maintains anesthesia in patients undergoing surgery or painful procedures. Propofol...
A blood clot in the lungs is called a pulmonary embolism (PE). The condition is created from a blood clot that formed in the leg, broke free and went to the lungs. Risk factors that increase the chance of developing blood clots in the leg include...
Atelectasis, which is a partial or total collapse of the lung, is one of the many post-operative complications of various types of surgery. Operations requiring anesthesia, orthopedic surgery performed in high-altitude locations and surgery that...
Having chronic hypertension that starts before pregnancy or during the first 20 weeks of pregnancy can cause complications. Chronic hypertension can have harmful effects on a fetus, and it also increases the risk of developing other diseases in...
Infant heart monitors, also known as apnea monitors, also assess breathing in babies. Most babies are on heart monitors because they have periods of apnea, where they stop breathing. When a baby stops breathing, his heart rate normally drops as...
Sweet potatoes are nutrient-rich food sources that you would do well to substitute for less healthy potatoes. While they do contain quite a few unhealthy refined carbohydrates, they are very high in vitamin A, and a good supply of fiber, manganese...
