Sls Bio12 Respiratio
SLS Bio12 Respiration JW
| Term | Definition |
|---|---|
| Alveoli | A small cell containing air in the lungs, a sac-like dilation of the alveolar ducts in the lung |
| Aortic Bodies | A cluster of chemoreceptors, baroreceptors and supporting cells located in the wall of the aortic of the aortic arch near the heart, and is sensitive to changes in blood pressure and levels of blood gases |
| Bicarbonate Ions | A salt of carbonic acid |
| Bronchi | Any of the larger air passages of the lungs, having an outer fibrous coat with irregularly placed plates of hyaline cartilage, an interlacing network of smooth muscle and a mucous membrane of columnar ciliated epithelial cells |
| Bronchioles | The tiny branches of air tubes within the lungs which are the continuation of bronchi and connect to the alveoli (air sacs) |
| Carbaminohemoglobin | A combination of carbon dioxide and hemoglobin, CO2HHb, being one of the forms in which carbon dioxide exists in the blood. |
| Carbon Dioxide | A chemical compound composed of two oxygen atoms linked to a single carbon atom by covalent bond, and essential to many biochemical and biological processes |
| Carbonic Anhydrase | An enzyme that catalyzes the decomposition of carbonic acid into carbon dioxide and water, facilitating the transfer of carbon dioxide from tissues to blood and from blood to alveolar air |
| Carotid Bodies | A chemoreceptor located near the bifurcations of the carotid arteries that monitors changes in the oxygen content of the blood and helps control respiratory activity |
| Cilia | Hair-like projection on the surfaces of some cells and of certain organisms |
| Diphragm | The thin muscle below the lungs and heart that separates the chest from the abdomen |
| Exhalation | The giving forth of gas or vapor |
| External Respiration | The bodily process of inhalation and exhalation; the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation |
| Hydrogen Ions | The positively charged ion of hydrogen, H+, formed by removal of the electron from atomic hydrogen and found in all aqueous solutions of acids |
| Inhalation | The drawing of air or other substances into the lungs |
| Intercostal muscles | Respiratory muscles that arise from the lower border of one rib and insert into the upper border of the adjoining rib, and contract during inspiration or respiration |
| Internal Respiration | The metabolic processes whereby certain organisms obtain energy from organic moelcules; processes that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood |
| Larynx | A cartilaginous structure at the top of the trachea; contains elastic vocal cords that are the source of the vocal tone in speech |
| Lungs | The lungs are a pair of breathing organs located with the chest which remove carbon dioxide from and bring oxygen to the blood. There is a right and left lung |
| Mucus | The free slime of the mucous membranes, composed of secretion of the glands, along with various inorganic salts, desquamated cells and leucocytes |
| Nasal Cavity | The proximal portion of the respiratory passages on either side of the nasal septum, lined with ciliated mucosa, extending from the nares to the pharynx |
| Oxygen | the oxygen plays a crucial role in various biochemical and physiological processes, such as in cellular respiration. Its presence makes cellular respiration about ten times more efficient in yielding ATP |
| Oxyhemoglobin | The bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs; oxyhemoglobin transports oxygen to the cells of the body |
| pH | It is a measure to determine the acidity or alkalinity of a solution or a substance |
| Pharynx | The cavity at the back of the mouth. It is cone shaped and has an average length of 76 mm and is lined with mucous membrane |
| Pleural Membrane | A pleural membrane is a body cavity that basically surrounds the lungs. It is a serous membrane that folds back onto itself in order to form a 2-layered membrane structure |
| Reduced Hemoglobin | |
| Respiratory Centre In The Medulla Oblongata | The region of neurons in the brain that receives afferent information that is then translated to signals controlling the sequence of breathing |
| Respiratory Tract | The air passages from the nose to the pulmonary alveoli, through the pharynx, larynx, trachea, and bronchi |
| Ribs | One of the curved bones attached to the vertebral column and supporting the lateral walls of the thorax |
| Stretch Receptors | Receptor's that are sensitive to elongation, especially those in golgi tendon organs and muscle spindles, but also those found in visceral organs such as the stomach, small intestine, and urinary bladder |
| Thoracic Cavity | The body cavity of the human body (and other animal bodies) protected by the thoracic walls, and located below the diaphragm and above the neck |
| Trachea | The windpipe. A fibrocartilaginous tube lined with mucous membrane passing from the larynx to the bronchi |
