The Respiratory System
| Question | Answer |
|---|---|
| Where does External Respiration occur? | Occurs in the lungs, the exchange of oxygen and carbon dioxide between the air inhaled into the lungs and the blood flowing thru the pulmonary capillaries |
| Where does Internal Respiration occur? | Occurs all over the body, exchange of oxygen and carbon dioxide between the blood in the capillaries all over the body and all the cells and tissues of the body |
| Which structures constitute the Upper Respiratory Tract? | All the structures outside the lungs: nose, mouth, pharynx, epiglottis, and larynx |
| Which structures constitute the Lower Respiratory Tract? | All the structures within the lungs: trachea, bronchial tree, and lungs |
| Where are the Lateral Ventricles located? | Blind pouches on each side of the larynx that project laterally into the space between the vocal cords and the vestibular folds (false vocal cords), these are often involved in treating a condition in horses called roaring. |
| 3 Functions of the Larynx | 1.) voice production 2.) prevention of inhaling foreign material 3.) control of airflow to and from the lungs |
| What does Surfactant do? | Helps reduce the surface tension (the attraction of water molecules to each other), this prevents the alveoli from collapsing as air moves in and out during breathing |
| What is Negative Intrathoracic Pressure and what does it do? | The pressure within the thorax is negative with respect to atmospheric pressure, so a partial vacuum exists in the thorax that pulls the lungs out against the thoracic wall. Also aides in return of blood to the heart |
| Which muscles are the Inspiratory Muscles? | Diaphragm and External Intercostal Muscles |
| Which muscles are the Expiratory Muscles? | Abdominal and Internal Intercostal Muscles |
| What is the Tidal Volume of air? | The volume of air inspired and expired during one breath |
| What is the Minute Volume of air and how is it figured out? | Volume of air inspired and expired in one minute. Multiply the tidal volume by the number of breaths per minute |
| What is the Residual Volume of air? | The volume of air remaining in the lungs after maximum expiration |
| What is the Mechanical System responsible for? | Sets the routine inspiration and expiration limits |
| What does the Chemical System do? | Monitors the levels of certain substances in the blood and directs adjustments in breathing if they get out of balance Monitors the levels of certain substances in the blood and directs adjustments in breathing if they get out of balance |
| What is the Syrinx? | Sound producing organ in birds, avian version of the larynx |
| What is the function of the Respiratory system? | the diffusion of gases between the atmosphere and the cells of the body |
| What is Ventilation? | the intake of fresh air |
| What are the combining forms for nose? | nas/o, rhin/o |
| What are Nares? | paired external openings of the respiratory tract |
| What are Endotherms? | warm blooded animals |
| What do the Nasal Turbinates do? | warm, humidify, and filter inspired air |
| What is a Nasogastric Tube? | tube that passes thru the nose down to the stomach |
| What is the rostral part of the nostrils and nasal cavity termed? | Vestibular |
| What is the combining form meaning partition? | Sept/o |
| What is mucus? | slimelike substance that is composed of glandular secretions, salts, cells, and leukocytes |
| What is responsible for the sense of smell? | Olfactory receptors |
| What is the lymphatic tissue that protects the nasal cavity and upper throat? | Tonsils |
| What is a Sinus? | Air filled or Fluid filled space |
| What are the names of the sinuses? | Frontal, Maxillary, Sphenoid, Palatine, Lacrimal, and Conchal |
| What is the Pharynx? | Throat |
| Where is the Nasopharynx? | the portion of the throat posterior to the nasal cavity and above the soft palate |
| Where is the Oropharynx? | the portion of the throat between the soft palette and the epiglottis |
| Where is the Laryngopharynx? | the portion of the throat below the epiglottis that opens into the voicebox and esophagus |
| What does the Epiglottis do? | acts like a lid and covers the larynx during swallowing |
| What is the Larynx and where is it? | voice box, located between the pharynx and trachea |
| Where is the Glottis? | the space between the vocal cords |
| What is another name for the Trachea? | Windpipe |
| What branches off the Trachea? | Bronchi |
| What are Alveoli? | air sacs in which most of the gas exchange occurs |
| What prevents the collapse of the Alveoli during expiration? | Surfactant |
| What is the main organ of Respiration? | Lung |
| What are the functional elements of an organ? | Parenchyma |
| What is the term for the framework for an organ? | Stroma |
| What is the term for the region between the lungs? | Mediastinum |
| What is the membrane sac encasing each lung? | Pleura |
| What is the inner layer of the membrane lining the outside of the lung? | Visceral Pleura |
| What is the outer layer of membrane lining the inner wall of the thoracic cavity? | Parietal Pleura |
| What is the potential space between the parietal and visceral pleura? | Pleural Space |
| What separates the thoracic and peritoneal cavities? | Diaphragm |
| What is the term for drawing in a breath? | Inhalation or Inspiration |
| What is the term for releasing a breath? | Exhalation or Expiration |

| What is an inadequate supply of oxygen to tissue despite an adequate blood supply? | Hypoxia |
| What refers to excessive amounts of carbon dioxide in the blood? | Hypercapnia |
| What refers to decreased levels of carbon dioxide in the blood? | Hypocapnia |
| What is Respiratory Acidosis? | An excessive amount of CO2 in the blood due to decreased ventilation causing a lower pH level in the blood |
| What is Respiratory Alkalosis? | CO2 levels are abnormally low due to increased ventilation |
| What suggests fluid accumulation? | Sounds of popping bubbles termed bubbling |
