SUMMARY

The discussion focuses on calculating the amount of oxygen (O2) absorbed by blood in the lungs per minute. Given that 100 ml of lung vein blood contains 14 ml of O2, the calculation for 70 ml of blood results in approximately 0.98 ml of O2. With the heart beating 70 times per minute, the total O2 absorption amounts to 68.6 ml. Participants confirm the calculations and suggest verifying the proportion used to determine the value of x.

PREREQUISITES
  • Understanding of basic physiology, specifically blood oxygenation processes.
  • Knowledge of proportions and ratios in mathematical calculations.
  • Familiarity with cardiovascular system dynamics, including heart rate and blood volume.
  • Basic algebra skills to solve for unknown variables in equations.
NEXT STEPS
  • Review the principles of blood oxygen transport and gas exchange in the lungs.
  • Study the mathematical concepts of proportions and ratios in greater detail.
  • Explore the relationship between heart rate and oxygen delivery in the body.
  • Investigate the physiological implications of oxygen saturation levels in blood.
USEFUL FOR

Students in biology or physiology, healthcare professionals, and anyone interested in understanding respiratory and cardiovascular interactions related to oxygen transport.

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.
Here's what I did
100ml blood -> 14 ml O2

70 ml blood -> x

x=0.98 ml O2

The heart beats 70 times
So 0.98*70=68.6 ml.
Is this solution right?

If you were trying to solve the proportion problem

##\frac{14\, ml\, O_2}{100\, ml\, blood} = \frac{x\, ml\, O_2}{70\, ml\, blood}##

You might want to check your calculation of x again.
