airway length - a large surface area means more friction
airway radius - halving the radius increases resistance 16-fold

It affected the education in WW2 primarily because of security issues for the schools.
Three common types of airway obstructions include foreign body aspiration, which occurs when an object lodges in the airway; swelling from anaphylaxis or severe allergic reactions, which can restrict airflow; and mucus plugs, often seen in conditions like asthma or chronic bronchitis, that block the airways. Each of these obstructions can lead to difficulty breathing and requires prompt medical attention.

During World War 2, virtually every occupied country had a significant resistance movement. However, the best known one was the French Resistance, also known as 'La Resistance Francaise.'
The diameter of the airway is the most important factor in determining airway resistance. A smaller diameter increases resistance, making it harder for air to flow. Factors such as mucus, inflammation, and constriction can also affect airway resistance.
Material resistance is not affected by color, texture, or surface finish. It is primarily determined by the material's intrinsic properties such as conductivity, thickness, and temperature.
Electrical resistance is primarily determined by the material's properties (resistivity, temperature, dimensions) and not affected by factors like voltage or current. However, the type of material, temperature, and length can impact resistance.
Airway resistance refers to the obstruction or restriction of airflow in the respiratory passages. Increased airway resistance makes it harder for air to flow in and out of the lungs, requiring more effort and energy during breathing. This results in an increased work of breathing as the respiratory muscles have to work harder to overcome the resistance and maintain adequate ventilation.

Emphysema is a COPD, chronic obstructive pulmonary disease, which means that there is poor airway due to resistance. The condition is characterized by a deterioration of the walls of the alveoli, which are the tiny air sacs that are needed for you to breath properly.
Increased airway resistance leads to increased negative intra-pleural pressure (more negative pressure), as it requires increased effort to overcome the resistance and maintain adequate airflow into the lungs. This increased pressure difference helps to keep the airways patent by promoting dilation of the bronchioles. If the resistance becomes too high, it can result in excessive negative pressure and potentially lead to airway collapse.
The resistance of an electrical conductor is primarily affected by its length, cross-sectional area, and the material it is made of. Longer conductors have higher resistance, while conductors with larger cross-sectional areas have lower resistance. Different materials have different resistivities, which also affect resistance.
there are four important factors that effecting the lung resistance . 1- lung volume 2- density and viscosity of the air breathed. 3- contraction of smooth muscles of the air way. 4- diameter of the airway.
Electrical resistance depends on the temperature but not the biased voltage.AnswerIt's resistivity that can be affected by temperature, which means that resistance is indirectly affected by temperature.
Resistance is the opposition to the flow of electric current. It is affected by the length, cross-sectional area, and resistivity of a material. As resistivity is affected by temperature, temperature indirectly affects resistance.
Light does not directly affect a thermistor, as its resistance is primarily determined by temperature changes. However, if light generates heat that affects the temperature of the thermistor, then it can indirectly alter its resistance. In general, thermistors are designed to be affected by temperature changes, not light.
