SUMMARY

The calculation of oxygen absorption in the lungs is based on the relationship between blood volume and oxygen content. Given that 100 ml of blood contains 14 ml of O2, the oxygen content for 70 ml of blood is calculated to be 9.8 ml O2. With a heart rate of 70 beats per minute, the total oxygen absorbed by the blood in the lungs per minute is 686 ml. This calculation confirms the accuracy of the method used, despite a minor typographical error in the initial data.

PREREQUISITES
  • Understanding of basic physiology related to blood and oxygen transport
  • Knowledge of unit conversion and proportional reasoning
  • Familiarity with cardiac output and heart rate concepts
  • Basic algebra for solving equations
NEXT STEPS
  • Research the physiological mechanisms of oxygen transport in the bloodstream
  • Learn about cardiac output calculations and their significance in health
  • Explore the effects of different heart rates on oxygen absorption
  • Investigate common typographical errors in scientific calculations and their implications
USEFUL FOR

Students studying human physiology, medical professionals interested in cardiopulmonary function, and educators teaching concepts related to blood oxygenation and cardiovascular health.

Homework Statement


100 ml blood of lung vein contains 14 ml O2. The volume of blood in the left ventricle is 70 ml. Find the amount of O2 the blood absorbs in the lung for a minute.

Homework Equations


100ml blood -> 14 ml O2
70 ml blood -> x

The Attempt at a Solution


Here's what I did
100ml blood -> 14 ml O2
70 ml blood -> x
x=9.8 ml O2
The heart beats 70 times
So 9.8*70=686 ml.

Looks good. That is, you omitted a decimal point in one of the numbers, but it s obvious it just a typo.
