CNS
Function of CNS
Receive process and respond to sensory information
No brain or spinal but all other nerves
What makes up the PNS
Known as the pacemaker
What is the SA Node?
This part of the respiratory system is responsible for exchanging oxygen and carbon dioxide and is found at the end of the bronchioles
What are the alveoli?
This process refers to the mechanical act of moving air in and out of the lungs, ensuring oxygen reaches the bloodstream
What is ventilation?
What are the main parts of the CNS
Brain and spinal cord
To maintain homeostasis
What is the function of PNS
Contraction phase; blood pumped out of chamber
This muscle is the primary muscle responsible for inhalation by contracting and allowing the lungs to expand.
What is the diaphragm?
This term describes the normal, regular rhythm of breathing that occurs at rest, typically 12-20 breaths per minute in adults.
What is eupnea?
The automatic response to stimulus
What is reflex
Control physiological functions deemed unconscious
What is the ANS ( autonomic nervous system)
Relax phase; blood fills the chamber
What is diastole?
This chronic lung disease, often caused by smoking, involves inflammation and narrowing of the airways, making it difficult to breath
What is chronic obstructive pulmonary disease (COPD)?
This part of the brainstem controls the rate and depth of breathing by responding to levels of carbon dioxide in the blood.
What is the medulla oblongata?
Lobe that focuses on sound/ audio signals
What is the temporal lobe
Stimulated systems related to survival and stress
What is “fight or flight “
Atrial contraction/ depolarization
What is p wave?
This tube connects the larynx to the lungs and divides into the left and right bronchi.
What is the trachea?
This structure acts as a passageway for air between the nasal cavity and the trachea and helps filter, warm, and moisten the air.
What is the pharynx?
Regulation of balance, posture, and muscle coordination
What is cerebellum
Helps regulate normal and resting function
What is “rest and digest”
To deliver substance to tissue ; remove byproduct from tissue
what is the function of blood?
This process involves the movement of oxygen from the alveoli into the bloodstream and carbon dioxide from the blood into the alveoli.
What is external respiration?
This condition, also known as "air trapping," is often seen in diseases like asthma and emphysema, where the lungs have difficulty expelling air.
What is obstructive pulmonary disease
