Breathing and Respiration in Animals. The process of breathing includes inhalation of air in the environment that is distributed in the human body tissues and throughout the respiratory system to perform various functions such as breathing in and exhaling to be able to consume oxygen and release carbon dioxide to be burned for energy. This process is known as respiratory breathing. The lungs have a series of bones and ligaments that are found at the end of the larynx and on top of the sternum. These bones and ligaments aid in moving the air into the bronchi and airway and expelling the air out of the lungs.
Breathing and Respiration in Humans and Other Animals. The diaphragm is the muscle that is found between the lungs and the ribs. This is used to expand the air into the lungs and push it out of the respiratory system. The muscles of the diaphragm can contract and relax to allow air to go through or relax and collapse in order to allow air to go through. A person can breathe deeply (breathe in) or very deeply (breathe out) depending on how their lungs are working.
Breathing and Respiratory in invertebrates. Most invertebrates have paired gills that are connected to their external areas. These paired gills are not usually connected directly to the respiratory organs of the animal. In some species, the paired glands are connected to the diaphragm. This means that animals without diaphragms have breathing and respiration as described above.
Breathing and Respiration in Humans and Other Animals. Breathing and respiration in humans are an important part of their life. When a person is alive, they are able to take in air from their lungs through their mouth and inhale oxygen from their lungs via their nose. Once they exhale all of the air is gone from their lungs, they need to replace the air with nitrogen, water, and stored energy (in the form of hemoglobin). There are four major systems that allow humans to respire: cardio-respiratory system, urogenital respiratory system, and gastrointestinal tract.
Cardio respiratory system is involved in all bodily actions including breathing and respiration. It starts from the brain and goes to the heart through the pulmonary tract. The bronchial tubes open and close to allow a sufficient amount of oxygen to enter the lungs and transport it to the circulatory system. The respiratory system involves all the parts of the body involved in breathing and respiration. This system includes the lungs, the trachea, the diaphragm, the bronchioles, the tracheal tubes, the larynx, the vocal chords, the accessory muscles, the abdomen, the skin, the urinary bladder, and the digestive tract.
The respiratory system is mainly involved in breathing but it also involves the distribution of oxygen throughout the body to the different organs. First it delivers oxygen to the lungs and second it distributes oxygenated gas to different parts of the body. Thirdly, it removes carbon dioxide from the lungs through the airways and fourthly it exchanges the carbon dioxide with fresh oxygen. It also helps to produce carbon dioxide and water to replenish the air.
Inhalation and exhalation are the terms used to describe breathing processes. Breathing in through the mouth and breathing out through the nose are known as ventilation. Respiration is the process of breathing out. During inhalation, air enters the lungs through bronchial tubes and the upper airway, while exhalation occurs when air leaves the lungs through the nasal cavity. The normal breathing cycle in humans is called tidal breathing which happens for about 3 minutes.
The three major respiratory systems are cardiovascular, uvular, and transcutaneous respiratory mechanisms. Cardiovascular respiratory system mainly includes diaphragm, heart, lungs, and capillaries and is commonly termed as cardio-respiratory system. The upper respiratory system is characterized by trachea, bronchial tubes, nose, mouth, larynx, and pharynx. Urinary respiratory system mainly includes kidneys, bladder, and ureters and is generally termed as urinal respiratory system. Last, but not least, is thermodermatic respiratory mechanism which provides homeostatic balance of respiratory hormones and involves the hypophosphatemia, hyperphosphatemia, and hypoxemia-like symptoms (e.g., cough, fever, etc.)
