Answer:
Mary's target heart rate is 103 beats per minute (bpm).
Explanation:
The maximum heart rate (MHR) is the rate at which the human heart of a given person reaches the highest demands. At rest, the heart rate is about 60 to 80 beats per minute.
MHR = 220 - age
So, for Mary: MHR = 220 - 14 = 206 beats per minute (bpm)
Now we can calculate Mary's target heart rate:
Target heart rate = MHR * 50% = 206 * 0.5 = 103 beats per minute (bpm)
Hope this helped!

Answer: Gasses are exchanged across the alveolar membrane.
The exchange of gasses takes place across the alveolar membrane of the lungs. Our respiratory system are composed of nose, pharynx, larynx, trachea, bronchi, and lungs (alveoli) where gas exchanges between the blood and external environment by diffusion. Moreover, during the gas exchange, the oxygen enters the blood while carbon dioxide enters the alveoli.
