Respiratory System
This airway, commonly known as the windpipe, has cartilage rings to keep it from collapsing as we breathe.
What is the trachea?
The brain and the spinal cord are the structures of this division of the nervous system.
What is the central nervous system?
These structures of the lymphatic system are found at the opening of the throat to guard against harmful organisms that might be inhaled or swallowed.
What are the tonsils?
The three main functions of the cardiovascular system are transportation, regulation, and this.
What is protection?
There are 12 pairs of these in the nervous system.
What are cranial nerves?
Millions of these air sacs increase the surface area of the lungs, making gas exchange extremely efficient.
What are alveoil?
This lobe of the brain is responsible for processing auditory stimuli (what we hear).
What is the temporal lobe?
These lymphatic system structures that filter lymph are found in various body areas including armpits, groin, and neck.
What are lymph nodes?
This connective tissue structure, found between the left atrium and left ventricle, ensures that blood flows in the proper direction.
What is the bicuspid valve?
This respiratory gas is produced as a byproduct of cellular respiration in the mitochondria.
What is carbon dioxide?
This respiratory system structure is a flap of tissue that covers the larynx when we swallow food and drinks.
What is the epiglottis?
Of sensory neurons, motor neurons, or interneurons, the cells in the brain and spinal cord that interpret and integrate incoming information.
What are interneurons?
Besides immunity, the lymphatic system also aids in the digestion of this nutrient, otherwise known as lipids.
What are fats?
This measurement is an assessment of how much force is exerted by blood pushing against artery walls during a heartbeat cycle.
What is blood pressure?
This is the largest organ of the lymphatic system and is responsible for immunity and red blood cell breakdown.
What is the spleen?
This lung function test is described as the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath.
What is vital capacity?
This division of the autonomic nervous system is responsible for the body's "rest and digest" activities.
What is the parasympathetic nervous system?
Of thymus, thyroid gland, and tonsils, the one that is NOT a structure of the lymphatic system.
What is the thyroid gland?
Blood leaving the left atrium is pumped into this, the largest of the body's arteries.
What is the aorta?
This very specialized type of muscle tissue is only found in the heart.
What is cardiac muscle tissue?
Along with the diaphragm, these muscles must contract in order for inhalation to occur.
What are the intercostal muscles?
This brain region is largely responsible for coordination of the muscular system, such as when we ride a bike or balance on one leg.
What is the cerebellum?
This lymph tissue is found in the digestive tract, to guard against disease-causing microbes being absorbed in the small intestine.
What are Peyer's patches?
This component of blood is essential for the stopping of blood loss.
What are platelets?
This ailment that often requires an inhaler results from spasm of the bronchial smooth muscle that severely obstruct the flow of air.
What is asthma?
