What is South Africa?
This is the amount of blood pumped by the heart per minute.
What is cardiac output?

What are oligodendrocytes?
This is the term for the tiny hair-like structures that line the respiratory tract and help move mucus and foreign particles out of the lungs.
What are cilia?
The Super Bowl trophy is named after this legendary coach.
What is the Vince Lombardi Trophy?
This is the volume of blood pumped with each heartbeat.
What is stroke volume?
This term refers to the specialized synaptic connection between the axon terminal of one neuron and the dendrite or cell body of another neuron.
What is a synapse?
A condition in which a person’s breathing is irregular, usually characterized by shortness of breath and rapid breathing.
What is tachypnea?
This ancient wonder of the world was located in Egypt and still stands today.
What is the Great Pyramid of Giza?
This phase is when the heart contracts.
What is systole?
This physiological process refers to the transmission of electrical signals along the axon, involving the movement of sodium and potassium ions.
What is an action potential?
The lack and or production of this lipid based molecule contributes to a dramatic increase in surface tension and drop in lung compliance.
What is surfactant?

Who is Babe Ruth?
The predominate receptor category in the parasympathetic nervous system.
What are cholinergic receptors?
This type of conduction, which occurs in myelinated axons, allows action potentials to travel more quickly by "jumping" from one neurofibril node to the other. This node is also known as the...
The nodes of Ranvier.
This condition is characterized by the collapse of the lung due to the loss of negative pressure in the pleural cavity, often following trauma or disease.
What is a pneumothorax?
The Boston Tea Party protested this British law in 1773.
What is the Tea Act?
This class of drugs is used to block the effects of acetylcholine at muscarinic receptors, commonly used to treat bradycardia and as pre-anesthetic agents.
What are anticholinergics?
This region of the brain is involved in autonomic functions like heart rate, breathing, and blood pressure, and is located in the brainstem.
What is the medulla oblongata?
