Assertion : Vocal cords consists of three pairs of mucous membrane that extend into the lumen of the larynx. Reason : Sound is produced by only two pairs of cords.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true and reason is not the correct explanation of assertionC. If assertion is true but reason is false.D. If both assertion and reason are false. |
|
Answer» Correct Answer - D Inside the larynx are prsent two paris of vocal cords. One pair is of false vocal cords which hs little to do wit sound production and the second inner pair is true vocal cords. When air is forced through the larynx, it causes vibration of the true vocal cords and sound is produced. The pitch of sound is determined by the tension on the vocal cords the greater the tension, the higher the pitch. |

What is Tidal volume? Find out the Tidal volume (approximate value) for a healthy human in an hour. |
|
Answer» Tidal volume is the volume of air inspired or expired during normal respiration. It is about 6000 to 8000 mL of air per minute. The hourly tidal volume for a healthy human can be calculated as: Tidal volume = 6000 to 8000 mL/minute Tidal volume in an hour = 6000 to 8000 mL `xx` (60 min) `=3.6xx10^(5)` mL to `4.8xx 10^(5)` mL` Therefore, the hourly tidal volume for a healthy human is approximately 3.6 `xx 10^(5)` mL to `4.8xx10^(5)` mL |
