respiratory system Flashcards
what is the primary function of the respiratory system?
The respiratory system’s main job is to move fresh air into your body while removing waste gases.
what is the secondary function of respiratory system?
Secondary functions of the respiratory system include voice production, body temperature and acid-base regulation, and the sense of smell. The structure of the respiratory system consists of the lungs and a complex system of tubes that connects them with the outside world.
what is the conducting zone?
The conducting zone consists of all of the structures that provide passageways for air to travel into and out of the lungs: the nasal cavity, pharynx, trachea, bronchi, and most bronchioles.
what is the respiratory zone?
The respiratory zone corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli. … The conducting tract consists of airways that transport gases into and out of the lungs and includes the trachea, bronchi, and bronchioles.
what is the nose?
nose, the prominent structure between the eyes that serves as the entrance to the respiratory tract and contains the olfactory organ. It provides air for respiration, serves the sense of smell, conditions the air by filtering, warming, and moistening it, and cleans itself of foreign debris extracted from inhalations.
what is the pharynx?
Anatomy of the pharynx (throat). The pharynx is a hollow tube that starts behind the nose, goes down the neck, and ends at the top of the trachea and esophagus. The three parts of the pharynx are the nasopharynx, oropharynx, and hypopharynx.
what is the larynx?
Anatomy of the pharynx (throat). The pharynx is a hollow tube that starts behind the nose, goes down the neck, and ends at the top of the trachea and esophagus. The three parts of the pharynx are the nasopharynx, oropharynx, and hypopharynx.
what is the trachea?
The trachea is the long tube that connects your larynx (voice box) to your bronchi. Your bronchi send air to your lungs. Your trachea is a key part of your respiratory system. The trachea is made of rings of cartilage. It is lined with cells that produce mucus.
what is the alveolar duct?
n. The part of the respiratory passages beyond the respiratory bronchioles, from which the alveolar sacs and alveoli arise. The smallest of the intralobular ducts in the mammary gland, into which the secretory alveoli open.
what is the alveolus?
any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange.
what is the alveolar sac?
Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
what is boyles law formula?
P1V1 = P2V2
what is boyles law?
a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
what does inspiration mean in anatomy?
The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward.
what does expiration mean in anatomy?
1a(1) : the act or process of releasing air from the lungs through the nose or mouth : exhalation. (2) : the escape of carbon dioxide from the body protoplasm (as through the blood and lungs or by diffusion) b archaic : the last emission of breath : death.
