Chapter 17, Problem 15CYU
Summary Introduction
To review:
The reason for the increased HR (heart rate) and SV (stroke volume) after running fast for a while.
Introduction:
Heart rate is defined as the number of times the heart beats in a unit time. A normal person should have a heart rate between 60 to 100 BPM (beats per minute). The SV is defined as the amount of blood whichis pumped out through the ventricle after a contraction. The normal person should have the SV of 50mL (milliliters) to 120mL.

Adam has been having some breathing difficulties. He decided to go on a hiking trip. The trip made him concerned about the health of his respiratory system as he was experiencing more difficulties breathing while hiking. He visited the doctor who prescribed a spirometry for Adam. The main reading the doctor was looking for is the Vital capacity. Why did the doctor decide to do measure the VC and what is your prediction of Adam’s VC and why? Would Adam’s breathing difficulties cause his blood pH to increase or decrease? Discuss
please give me new ansewer!!
my age is 23
height is 5 "2in
female
1.using height and gender , calculate your predicted vital capacity but add 5 years to current age.Then do the calculation again, but add 10 years to your current age .what changes are predicted in vital capacity as one ages?what do you think the reason for these age related changes?
Ilike Running is training for a marathon. While training, his volume of air in each breath is 1.5 L and he takes approximately 15 breaths per minute. His total lung capacity is 5500 mL and his residual volume is 1500 mL. Ilike has a blood pH of 7.2 and his cardiac output is 4.95 L/min. His heart is pumping 172 times per minutes. Finally, his expiratory reserve volume is 750 mL. In order to increase his performance, Ilike wants an analysis of his current exercise values. Please determine the following based on the information listed above.

- Daniel, the swimmer with the fastest time on the college swim team, routinely hyperventilates before a meet, as he says "to sock some more oxygen into my lungs so I can swim longer without having to breathe." "Furthermore, my heart won't have to adjust it's output". First of all, what basic fact about oxygen loading has Daniel forgotten (a lapse leading to false thinking)? Do you think that hyperventilation will provide him with enough oxygen to increase his endurance during the race?arrow_forwardYou found this figure in an old physiology textbook, and you are trying to understand it.
