Question | Answer |
---|---|
Alveoli | Small sacs that allows gas exchange between O2 and CO2 |
Aortic Bodies | One of several small clusters of chemoreceptors, baroreceptors, and supporting cells located along the aortic arch. |
Bicarbonate ions | HCO3− |
Bronchi | Two main branches of the trachea that go into the lungs |
Bronchioles | Smaller tubes that leads to the alveoli |
Carbaminohemoglobin | A compound of hemoglobin and carbon dioxide, 10% of carbon dioxide is carried in blood this way |
Carbon Dioxide | A chemical compound composed of two oxygen atoms linked to a single carbon atom; waste product of cellular respiration |
Carbonic Anhydrase | An enzyme that catalyzes the reaction of dissolved bicarbonates and carbon dioxide |
Carotid Bodies | A small mass of receptors in the carotid artery sensitive to chemical change in the blood. |
Cilia | A short, microscopic, hairlike vibrating structure |
Diaphragm | A dome-shaped, muscular partition separating the thorax from the abdomen |
Exhalation | The process or action of exhaling |
External Respiration | Exchange of gases at the alveoli |
Inhalation | The action of taking in O2 |
Internal respiration | Exchange of gases at the tissues |
Larynx | The hollow muscular organ forming an air passage to the lungs; the voice box |
Oxyhemoglobin | A bright red substance formed by the combination of hemoglobin with oxygen, present in oxygenated blood |
Pharynx | The membrane-lined cavity behind the nose and mouth, connecting them to the esophagus. |
Pleural membranes | The pleural cavity is the potential space between the two pleurae of the lungs. |
Reduced Hemoglobin | A combination of hemoglobin and a hydrogen ion |
Respiratory centre | Medulla oblongata; senses O2 and CO2 levels in the blood |
Stretch receptors | Receptor's that are sensitive to elongation; found in the alveoli |
Thoracic Cavity | the cavity in the vertebrate body enclosed by the ribs between the diaphragm and the neck |
Trachea | A large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes |
