Respiratory System Flashcards

Flashcards about the respiratory system

What are the main functions of the respiratory system?

Gas exchange, breathing, contains receptors for smell, protection from dust and microbes, regulating blood pH.

Name the components used to pull air from outside the body into the respiratory system.

Mouth and nose.

What is/are the hollow area(s) between bones in your head that help regulate temperature and humidity of the air we breathe?

Sinuses

Which component of the respiratory system delivers air from your mouth and nose to the trachea?

Pharynx

What is the passage connecting the throat and lungs?

Trachea

What connects to the lungs from the bottom of the windpipe?

Bronchial tubes

Which two organs remove oxygen from the air and pass it to your blood?

Lungs

Where does the exchange of oxygen and carbon dioxide take place in the lungs?

Alveoli

What are the small branches that lead to the alveoli called?

Bronchioles

What separates your lungs from your chest?

Pleura

Which muscle at the base of the lungs contracts to expand lungs, creating a vacuum sucking in air?

Diaphragm

What is the exchange of air between the body and the outside environment called?

External respiration

What is the process of bringing oxygen to the cells and removing carbon dioxide called?

Internal respiration

What is the process of drawing gases into the lungs?

Inhalation

What is the process of forcing gases out of the lungs?

Exhalation

What are the 'pipes' called, through which air enters your lungs?

Bronchi

What is the network of blood vessels surrounding each alveolus called?

Capillaries

What is the movement of oxygen and carbon dioxide between the air in the alveoli and the blood in the capillaries called?

diffusion

Describe what happens to oxygen and carbon dioxide when you breathe in.

Oxygen travels across the walls of the alveoli into the bloodstream and carbon dioxide crosses from the blood in the capillaries into the air in the alveoli and is then breathed out.

What inflammatory condition in the airways makes breathing difficult?

Asthma

Name the components of an Asthma attack.

Bronchospasm, inflammation, and Mucus production

What are the causes of Pneumonia?

Caused by bacteria, viruses or fungi

Name the method of treatment for each cause of Pneumonia.

Antibiotics for Bacteria, No Treatment for Virus, and Antifungal Medication for Fungus

What is cystic fibrosis?

Inherited disorder that causes damage to the lungs as well as other organs

How does the skeletal system work with the respiratory system?

The skeletal system provides protection around your lungs and heart.

How does the circulatory system work with the respiratory system?

The bloodstream delivers oxygen to all your organs and tissues.

How does the muscular system work with the respiratory system?

The diaphragm plays a huge role in allowing your lungs to push air in and out, and Provides oxygen to muscles and removes carbon dioxide.

How does the nervous system work with the respiratory system?

By provides oxygen to the brain
