Respiratory Anatomy & Functions
This primary function of the respiratory system involves swapping oxygen into the body and releasing carbon dioxide.
What is gas exchange?
This respiratory condition involves airway swelling and constriction, often triggered by cold air, exercise, or allergens.
What is asthma?
This organ is a muscular bag that churns food using strong muscular contractions.
What is the stomach?
This is the primary function performed by the large intestine.
What is water absorption?
This gas element is taken in during breathing to keep us alive.
What is oxygen?
The types of digestion that happens throughout our body
What is mechanical and chemical?
Besides gas exchange, these are two additional functions performed by parts of the respiratory system
What are talking and smelling?
Long-term exposure to irritants like cigarette smoke can cause permanent damage known by this four-letter abbreviation.
What is COPD (Chronic Obstructive Pulmonary Disease)?
Food travels down this muscular tube from the throat into the stomach.
What is the esophagus?
This condition occurs when stomach acid backs up into the esophagus.
What is acid reflux (or heartburn)?
This compound is produced as a waste product of respiration and exhaled out.
What is carbon dioxide?
This chain of organs is how food travels through and how it is broken down.
What is the digestive system?
This organ serves as a shared passageway for both food and air.
What is the pharynx?
Caused by a virus, this contagious infection leads to fever, body aches, cough, and a sore throat.
What is Influenza (or the Flu)?
This type of digestion breaks food down physically without altering its chemical structure
What is mechanical digestion?
This issue happens when the large intestine reabsorbs too much water from leftover waste.
What is constipation?
Carbohydrates, proteins, fats, vitamins, and minerals make up these five essential groups.
What are the five nutrient groups?
This dome-shaped muscle beneath the lungs contracts and relaxes to inflate and deflate them during breathing.
What is the diaphragm?
These structure-preserving rings surround the windpipe to prevent it from collapsing.
What are rings of cartilage?
This condition causes the alveoli to fill with fluid due to a bacterial, viral, or fungal infection
What is pneumonia?
Most of the body's nutrient absorption takes place inside this specific organ.
What is the small intestine?
Eating gluten triggers an autoimmune response that damages villi in people with this condition.
What is Celiac Disease?
Energy, tissue repair, and temperature regulation are three reasons your body needs fuel; this is the fourth.
What is growth?
This tiny flap closes over the airway when you swallow to prevent food from entering the trachea.
What is the epiglottis?
These tiny, grape-like air sacs inside the lungs are where the actual exchange of oxygen and carbon dioxide takes place.
What are alveoli?
This viral infection specifically affects the tubes branching off the trachea, leading to persistent coughing and chest discomfort.
What is acute bronchitis?
These tiny finger-like projections line the small intestine to increase its surface area for absorption.
What are villi?
This condition is an inflammation of the stomach and intestines often caused by viruses or contaminated food.
What is gastroenteritis/stomach bug?
This form of digestion changes the chemical composition of food into tiny molecules the body can absorb.
What is chemical digestion?
This condition occurs when the large intestine absorbs too little water, leaving waste overly liquid.
What is diarrhea?
