Respiratory System: Structure and Function

Anatomy and Physiology12 CardsCreated 4 months ago

This deck covers the structure and function of various components of the respiratory system, including the nasal cavity, pharynx, larynx, and more. It provides a detailed look at how these structures work together to facilitate breathing and gas exchange.

Describe the structure and function of the nasal cavity
Air enters body through the nasal cavity. Hairs filter out unwanted material.
Describe the structure and function of the mouth
The mouth is a backup way for air to enter body if nose isn't working.
Describe the structure and function of the pharynx
The pharynx is a passageway between nose, mouth, and larynx.
Describe the structure and function of the epiglottis
The epiglottis is a flap of cartilage protecting the larynx from food or other unwanted material.
Describe the structure and function of the larynx
Located just below the epiglottis, and just before the trachea, the larynx contains the vocal chords. It is also known as the 'voice box'.
Describe the structure and function of the trachea
The tracheal is an armored tube that allows air to pass from the pharynx to the lungs.

These flashcards explain key concepts related to oxygen use during and after exercise, including EPOC (Excess Post-exercise Oxygen Consumption), oxygen deficit, and the two stages of recovery. They highlight how the body restores itself to a pre-exercise state and compensates for oxygen demands during physical activity.

Describe the structure and function of the trachea
The tracheal is an armored tube that allows air to pass from the pharynx to the lungs.
Describe the structure and function of the bronchus
The bronchi are tubes that take air from the trachea into the lungs. Each bronchus splits into smaller bronchioles. One bronchus, two bronchi. Bronchus is latin for 'branch'.
Describe the structure and function of the bronchiole
A bronchiole is a small tube that splits into even smaller bronchioles. It distributes air throughout the lungs. Bronchiole is latin for 'small branch'.
Describe the structure and function of the alveoli
Alveoli are tiny sacs of air at the end of the smallest bronchioles. They are covered in tiny blood vessels called capillaries. Their purpose is to allow gas exchange - oxygen goes from the air into the blood, and carbon dioxide goes from the blood into the air.
Describe the structure and function of the lung
The lungs are two large organs designed to allow gas exchange (respiration). Oxygen goes from the air to the blood to be used by cells to break down sugar for energy, and carbon dioxide (a waste product of breaking down sugar) goes from the blood into the air.
Describe the structure and function of the brain stem
The brain stem senses the amount of carbon dioxide in the blood. If the CO2 level is high enough, it signals the diaphragm to cause breathing to happen.
Describe the structure and function of the diaphragm
The diaphragm is a sheet of muscle that tenses to pull air into the lungs, and relaxes to allow air back out. It receives signals from the brain stem.
