Which of the following is not part of the passageway through which air travels as it moves into the alveoli?

A. Upper esophageal sphincter

B. Trachea

C. Respiratory bronchioles

D. Glottis

E. pharynx

Expert Solution

The correct option for this question is upper esophageal sphincter.

The rest all options serves as the common passage for air and food particles.

The route of Air which we inspire is as follows:

Nostrils
Nasal cavity
Pharynx
Larynx (glottis is a part of larynx)
Trachea
Primary bronchi
Secondary bronchi
Tertiary bronchi
Bronchioles
Alveoli

Alveoli is the site where exchange of gas takes place.

Part 1: Ball Toss: Conservation of energy, or not, as a ball travels through the air Open BallToss.cmbl with LoggerPro. Find the height and velocity of the ball at three points: initial, right after it left the hands, peak, and final, right before it was caught. Compute the potential energy, kinetic energy, and PE + KE of the ball at these three points. Use whatever reference point seems convenient -- the location of the detector is fine. Mass of ball:...

A 600 Mrad/s EM wave travels through air and is polarized with the electrical field normal with the plane of incidence. This wave impinges on the surface of a perfect conductor on plane z=0 at 50º and its electric field has an amplitude of 2V/m. Find the electrical field resulting from incident and reflected wave on frequency domain. Also, find the current density at the interface between air and the perfect conductor

--Suppose a ray of light travels from air into water. a. If the air has an index of refraction of n = 1.0, and the light enters the water with an angle of 55 degrees to the normal, and the refracted angle is 38 degrees from the normal, what is the index of refraction of the water? b. Can total internal reflection occur when the light ray passes from the air to the water? Why or why not? --Which of...

Air flows through a nozzle which has inlet areas of (10 cm2 ). If the air has a velocity of (120 m/s) a temperature (300K) and a pressure of (700kpa) at the inlet section and a pressure of (250kpa) at the exit, find the mass flow rate through the nozzle and the velocity at the exit of the nozzle, assuming one- dimensional isentropic flow. (R=287 J/kg. K), (K=1.4). (25%)
