Respiratory Tract

The diaphragm separates the chest and the abdomen as well as this it has a large role in breathing. The diaphragm moves down when we breathe in which expands the chest cavity making room for air to enter through the nasal cavity or mouth. When we breathe out the diaphragm moves upwards, forcing the chest cavity to reduce in size and pushing the gases in the lungs up and out of either the nose or mouth.

What are the uses of drugs used to treat lower respiratory tract disorders: sympathomimetics, anticholinergics, inhaled steroids, lung surfactants, and mast cell stabilizers?

The primary muscle of respiration is the diaphragm. The nerve that initiates this muscle is the phrenic nerve.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs.

I would tell the doctor to stop if he didn’t start and grab a manual ventilator and try to find a replacement mechanical ventilator.

During inspiration, the diaphragm and the surrounding muscles contract. The diaphragm moves down increasing the volume of the chest cavity, and the surrounding muscles pull the rib up to allow further increase in volume. This increase of volume decreases the air pressure in the alveoli

The respiratory system provides a network of muscles and organs that helps a human breath. It brings in oxygen though inhaling and eliminates carbon dioxide through exhaling.

Shortness of breath and sudden chest pain are the primary symptoms. The chest pain is typically localized to the affected side. Tiredness may also be a symptom.

The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

Appropriate respiratory PPE should be chosen according to a risk assessment that takes account of the infective micro-organism, anticipated activity and duration of exposure. Respiratory PPE must fit the user correctly and staff must be trained in how to use and adjust it in accordance with Health and Safety Executive (2012) regulations. Staff should not use FFP3 respirators unless fit tested as safe. Figs 1 and 2 outline factors influencing the choice of single-use masks for use when treating patients who have respiratory infections.

As we breathe in, the muscles in the chest wall force the thoracic area, ribs and connective muscles to contract and expand the chest. The diaphragm is contracted and moves down as the area inside the chest increases as air enters the lungs. The lungs are forced open by this expansion and the pressure inside the lungs becomes enough that it pulls

The respiratory system is a series of organs in which is responsible for taking in oxygen and releasing carbon dioxide. The main organ in the respiratory is the lungs which helps with the prosses of exchanging gases as we breath. Red blood cells collect and use the oxygen to carry around the body to parts that need it. The body needs oxygen to survive because when without it, it would be fatal which is why the respiratory system is important.

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is
