Please help with question 20 21 and 22

QUESTION 20 1 points Save Answer If an individual has a respiration rate of 21 breaths per minute and a VT of 1250ml, what is their MV? ref: textbook chapter 2g respiratory system--section "hung volumes and capacities") O26,025ml 59.52ml O 1271ml O 26,250ml QUESTION 21 1 points Save Answer Collectively, the conducting airways with air that does not undergo respiratory exchange are known as the anatomic dead space. Because of the anatomic dead space air not all of the minute ventilation undergoes gas exchange. (ref lexibook chapler 23 respiralory system-seclion "ung volumes and capacilies") O True O False QUESTION 22 1 points Save Answor Which of the following choices best describes Alveolar Ventlation Rate (AVR)? (ref: textbook chapter 23 respiratory system--section "hng vohomes and capacities) is the volume of air that actually reaches the respiratory zone and is involved in gas exchange O is the volume of air that actually does not reach the respiratory zone and is not involved in gas exchange O is the amount of air exhaled not involved in gas exchange O none of the above

Explanation / Answer

Mv(minute volume)is amount of gas inhaled or exhaled per minute.

VT=1250ml. Breaths= 21===>minute volume=VT*respiratory rate

=1250*21=26250ml

True,due to anatomical dead space not all the minute ventilation undergoes gas exchange

Alveolar ventilation is actually volume of air that reaches respiratory zone and is involved in gas exchange
