Once your body has used the oxygen in the blood, the deoxygenated blood returns to the capillaries. When you breathe air out or exhale, the process is the opposite of when you inhale. The heart sends the oxygenated blood to the cells in your body. The oxygen attaches to red blood cells and travels to the heart. Oxygen in the air passes through the alveoli into the capillaries. The air travels through the bronchi and the bronchioles and into the alveoli. Tiny hair-like structures in the trachea, called cilia, filter the air to help keep mucus and dirt out of your lungs. The air that you inhale through your nose or mouth travels down the trachea. When you breathe air in or inhale, your diaphragm flattens and your ribs move outward to allow your lungs to expand. The capillaries move oxygen and carbon dioxide in and out of your blood. Each alveolus is covered in small blood vessels called capillaries. There are about 600 million alveoli in your lungs. The end of each bronchiole has tiny air sacs called alveoli. There are approximately 30,000 bronchioles in each lung. These smaller air tubes are called bronchioles. Once in the lung, the bronchi branch off throughout the lung and become smaller. The left main stem bronchus goes into the left lung, and the right main stem bronchus goes into the right lung. The bottom of the trachea separates into two large tubes called the main stem bronchi. The trachea or windpipe is located in your throat. The diaphragm is a dome-shaped muscle that works with your lungs when you breathe.įrom your nose and mouth, air travels towards your lungs through a series of tubes. A person needing this remedy is typically very irritable and impatient, with a general feeling of chilliness.Your lungs are located inside of the ribcage in your chest. Both physical effort and mental exertion can make things worse, and warmth and sleep often bring relief. Overindulgence in stimulants, alcohol, sweets, or strong spicy food can bring on or aggravate an episode. Indications for this remedy include a tense, constricted feeling in the chest during asthma attacks, with pressure in the stomach. Wheezing and breathing difficulties are aggravated by exertion, and episodes tend to be worse in the very early morning. The person may hold the chest while coughing, because it feels so weak. This remedy is sometimes indicated when asthma attacks are brought on by exposure to mold and dampness. (Children may even shriek and hit, though they often calm down if someone carries them.) The person seems hypersensitive and may be extremely irritable and agitated. The cough is often worse around nine p.m., and may continue into the night. Feeling worse in the evening, and worse from talking, eating, or lying down are other indications for this remedy.Īsthma with a dry, hard, irritating cough that starts after being exposed to moving air, or after becoming overexcited and angry, may be helped with this remedy. Gas and digestive upset are also likely, and sitting up and burping offers some relief. The person may be very cold (especially hands and feet), yet feel a need for moving air, wanting to sit beside a fan or open window. This remedy may be indicated when a person feels weak or faint with a hollow sensation in the chest. The problems often start while the person is asleep (typically before midnight). The person may feel best when sitting up and tilting the head back, or when leaning forward. Breathing can be labored, with a sawing sound, and not much mucus is produced. ( Pulsatilla is often useful in children’s illnesses.)Ī hard or “barking” cough during an asthma attack is a strong indication for this remedy. A person who needs this remedy is likely to be changeable and emotional, wanting a lot of attention and comforting. Tightness in the chest tends to be worse in the evening and at night, and is relieved by cool fresh air. Coughing brings up yellow-colored mucus, with gagging and choking. Wheezing that starts when a person gets too warm (especially in a stuffy room), or after eating rich food, can indicate this remedy. The person may sweat a lot and feel clammy or nauseous, be worse from motion, and sometimes worse from warmth. Mucus collects in breathing tubes, but the person has difficulty coughing much out. Wheezing can come on suddenly with a feeling of suffocation and heaviness in the chest. Warmth often brings improvement.Ĭoughing spasms that lead to retching or vomiting strongly indicate this remedy. General chilliness is usually seen, with burning pains in the chest and heat in the head. The person can be thirsty, taking frequent tiny sips. Dry wheezing may progress to a cough that brings up frothy whitish fluid. Breathing problems tend to be worse while lying down, better when sitting up, and may begin, or be the most intense, between midnight and two a.m. A person needing this remedy can feel exhausted, yet be very restless and anxious.
