Digestive System Basics
This macromolecule provides the body with energy and is found in foods like bread and pasta.
What are carbohydrates
Humans have these four types of teeth, each specialized for different functions in digestion.
What are incisors, canines, premolars, and molars?
Respiration requires these two essential elements.
What are oxygen (O₂) and carbon dioxide (CO₂)?
This muscular organ pumps blood throughout the body.
What is the heart?
This lung is smaller to make room for the heart.
What is the left lung?
These are the four main stages of food processing in the human digestive system.
What are ingestion, digestion, absorption, and elimination?
The esophagus moves food to the stomach using this wave-like muscle movement.
What is peristalsis?
Fish use these two adaptations to breathe underwater.
What are gills and the operculum (gill cover)?
Veins carry this type of blood, while arteries carry this type.
What is deoxygenated blood (veins) and oxygenated blood (arteries)?
Bronchi branch into these smaller tubes inside the lungs.
What are bronchioles?
Herbivores have a longer alimentary canal than carnivores for this reason.
What is to allow more time for breaking down tough plant material?
The liver, pancreas, and gallbladder are known as these types of digestive organs.
The liver, pancreas, and gallbladder are known as these types of digestive organs.
This is the correct path of air from the mouth/nose to the alveoli.
What is mouth/nose → pharynx → larynx → trachea → bronchi → bronchioles → alveoli?
Blood pressure is measured using this device.
What is a sphygmomanometer (BP cuff)?
These tiny blood vessels facilitate the exchange of oxygen, carbon dioxide, and nutrients between blood and tissues.
What are capillaries?
This disease occurs when the body cannot properly regulate blood sugar, and it is often managed with artificial insulin and exercise.
What is diabetes?
This part of the digestive system absorbs water and forms solid waste.
What is the large intestine (colon)?
Gas exchange in the lungs occurs in these tiny air sacs.
What are alveoli?
The circulatory system delivers this from the digestive system to the body's cells.
What are nutrients?
Hypertension is another term for this condition.
What is high blood pressure?
This structure in the small intestine increases surface area for nutrient absorption.
What are villi?
These three organs work together to aid digestion by producing bile, enzymes, and other digestive secretions.
What are the liver, pancreas, and gallbladder?
This flap of cartilage prevents food from entering the trachea when swallowing.
What is the epiglottis?
These are the four chambers of the human heart.
What are the left atrium, right atrium, left ventricle, and right ventricle?
The two largest blood vessels in the body that transport blood to and from the heart.
What are the aorta and vena cava?
