During exercise, the increased activity of the muscles increases oxygen consumption and production of carbon dioxide. The respiratory system, in conjunction with the cardiovascular system, must adjust to meet these demands. These additional...
When you travel to high altitudes, the air pressure is lower, meaning fewer oxygen molecules are present in the air. Kenneth Baillie, a clinical lecturer in anesthesia and intensive care medicine at the University of Edinburgh, reports for every...
Your body uses oxygen to produce energy. Oxygen cannot be stored in the body and muse be continually inspired. Therefore as your body expends more energy you must respire more. Your breathing rate is controlled by several factors including...
All adults in the United States are encouraged to get at least 30 minutes a day of exercise most days of the week, according to recommendations by the American Heart Association. Exercise relies on a complex set of reactions within your body to...
Increased respiratory rate is one of the most obvious adaptations you make to meet the demands of exercise. The rate of blood flow and gas exchange throughout the pulmonary system will increase during exercise to supply sufficient amounts of...
Asthma's primary cause is not known, but researchers believe that sufferers have a genetic predisposition towards allergies and allergic reactions. It is also believed that early exposure to allergens and infections in infancy, when the immune...
Breathing provides life-sustaining oxygen and rids the body of the gaseous waste product carbon dioxide. The respiratory control center in the brain stem receives various types of input from sensors in the body that influence the breathing rate....

The spine--also referred to as the backbone--curves naturally as it extends from the skull to the hips. Kyphosis is a medical term for a condition involving an unnatural curvature of the spine. With kyphosis, the spine causes a bowing of the back....
The respiratory system controls your breathing, providing oxygen to your body and eliminating carbon dioxide. Exercise causes muscle movement, increasing carbon dioxide in your body and resulting in an increased respiratory rate -- the frequency...
Exercise is one of the keys to living a long and healthy life, and it should be included in your weekly routine at least 30 minutes a day most days of the week, suggests the American Heart Association. When approaching exercise, you have two main...
Breathing is a fundamental process needed to sustain life. Still, it is only a part of the complex oxygen, carbon-dioxide swapping cycle called respiration. This process begins upon inhalation, allowing oxygen to flow deep within the lungs and...
Asthma is a chronic condition involving inflammation in the airways. According to the Centers for Disease Control and Prevention, about seven million children currently have asthma in the United States. Despite improvements in prevention and...
An aggravation of asthma is also known as an asthma exacerbation. The word exacerbation is used when there is a worsening of the disease or an increased severity of the signs and symptoms. Exacerbations can range from mild to severe. Regardless of...
