The lower respiratory system, or lower respiratory tract, consists of the trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange.
What is the function of the upper respiratory tract quizlet?

What is the upper airway?
Upper Airway It is the region between the palate and the hyoid bone, anteriorly divided from the oral cavity by the tonsillar arch. The hypopharynx connects the oropharynx to the esophagus and the larynx, the region of pharynx below the hyoid bone.
Where does the upper airway begin?
The upper airways begin with the nasal cavity and continue over nasopharynx and oropharynx to the larynx and the extrathoracic part of the trachea. The structure and function of this system have a major influence upon the conduction of the air to the lower airways [1].
Is it possible to forget to breathe?
Central sleep apnea is a sleep disorder in which you briefly stop breathing during sleep. Moments of apnea can occur repeatedly throughout the night as you sleep. The interruption of your breathing may indicate a problem with your brain’s signaling. Your brain momentarily “forgets” to tell your muscles to breathe.
Is 9 breaths per minute bad?
Bradypnea is an abnormally slow breathing rate. The normal breathing rate for an adult is typically between 12 and 20 breaths per minute. A respiration rate below 12 or over 25 breaths per minute while resting may signal an underlying health problem.
Why did I stop breathing for a second?
What is sleep apnea? Sleep apnea is a serious sleep disorder. People who have sleep apnea stop breathing for 10 to 30 seconds at a time while they are sleeping. These short stops in breathing can happen up to 400 times every night.
Where is the upper respiratory system located?
Upper respiratory tract: Composed of the nose, the pharynx, and the larynx, the organs of the upper respiratory tract are located outside the chest cavity.
Which of the following is not a part of the upper airway?
Trachea is not a part of the upper respiratory system.
What are the 3 main functions of the respiratory system quizlet?
- Regulate blood pH.
- Obtain carbon dioxide for the body.
- Produce vocal sounds.
- Obtain oxygen for the body.
- Produce ATP.
What is the primary function of the respiratory system quizlet Chapter 21?
The primary function of the lungs is gas exchange. Oxygen is transported to the body tissues, and carbon dioxide, a waste product, is transported out of the body.
What is the main function of a diaphragm?
The diaphragm is a muscle that helps you inhale and exhale (breathe in and out). This thin, dome-shaped muscle sits below your lungs and heart. It’s attached to your sternum (a bone in the middle of your chest), the bottom of your rib cage and your spine.
What are the 4 types of respiration?
- Pulmonary Ventilation. moving air into and out of the lungs. …
- External Respiration.
- Transport. transport of oxygen and carbon dioxide between the lungs and tissues.
- Internal Respiration. diffusion of gases between the blood of the systemic capillaries and cells.
What are the functions of the respiratory system Chapter 13?
What are the functions of the respiratory system? The respiratory system works with the circulatory system to provide oxygen and to remove waste products of metabolism. The respiratory system also helps to regulate the pH of the blood.
What are the functions of the respiratory system AES quizlet?
It brings oxygen into the body and removes carbon dioxide through the breathing process.
What is the difference between upper and lower respiratory tract?
The upper respiratory tract includes the nose, pharynx, and larynx. The lower respiratory tract consists of the trachea, bronchial tree, and lungs. These tracts open to the outside and are lined with mucous membranes. In some regions, the membrane has hairs that help filter the air.
