Respiratory System
Supported by rings of cartilage, this cylindrical tube travels down to the primary bronchi and relies on the epiglottis to ensure food doesn't enter it.
Trachea
If you know two of the variables for voltage, resistance, and current, you can solve for the third using this fundamental rule.
Ohm's Law
This field studies patterns of disease and health conditions in populations and helps scientists understand how outbreaks spread.
Epidemiology
When starting a cryptogram, a single-letter word is a great place to begin because it is almost always "A" or this other vowel.
I
What should you wear during Crime Busting?
Resembling a bunch of grapes, these thin-walled structures provide a large surface area and make direct contact with capillaries for gas exchange.
Alveoli
Resistors connected in series have the same current passing through them, but resistors in this branching formation share the same voltage drop.
Parallel
This term describes the total number of existing cases of a disease in a population at a single point in time.
Prevalence
If you spot a four-letter word where the first and last letters are exactly the same, the host notes it is very typically this word.

What is the chemical formula and structure of Sand?
SiO2, as a Giant Covalent Structure
Having only two lobes instead of three, this specific organ features a "cardiac notch" to give the heart some room.
Left Lung
When wires split in a circuit, the sum of the current in the branches must equal the total current entering the junction in order to satisfy the conservation of this.
Charge
Epidemiologists use this term to describe the number of new cases that develop in a population over a specific period of time.
Incidence
Because it is the most common word in the English language, a three-letter coded word starting with "T" and ending with "E" is almost always this definite article.
the
Your nervous system regulates involuntary breathing by monitoring the blood's pH, which becomes more acidic due to an increase of this waste gas.
Carbon Dioxide
Because it has a near-zero resistance, you must be careful to connect this current-measuring device in series, otherwise you might damage it.
Ammeter
This type of study compares people who have a disease to similar people who do not in order to identify possible causes or exposures.
If you spot a four-letter word in a cipher where the first and last letters are exactly the same, it is highly likely to be this common conjunction and pronoun.
that
Produced by type 2 alveolar cells, this substance made of phospholipids and proteins lowers surface tension to keep the alveoli from collapsing and is a crucial treatment for premature babies.
Surfactant
A voltmeter is attached in parallel to measure voltage without altering the circuit; it accomplishes this by having a resistance so high it is considered to be this.
Infinite
This method involves tracking the interactions and locations of infected individuals to identify how a disease is transmitted.
Contact Tracing
Solvers often use a chart to count how many times each encoded letter appears. By comparing these counts to known English averages, they are performing this type of analysis.
