Aperson with a tidal volume of 450 ml (milliliters), a vital capacity of 4000 ml, and a residual volume of 1000 ml would have a potential total lung capacity of a. 4000 ml b. 5000 ml c. 1450 ml d. 4450 ml

Option B

Explanation:

The total lung capacity (TLC) is the maximum volume of air that can be filled with in the lungs of an organism  

The general formula for total lung capacity  is  

Where ,  

TV is tidal volume

IRV is  inspiratory reserve volume

ERV is expiratory reserve volume

And RV is Residual volume  

Vital capacity (VC) is given by  

However, by thumb rule  vital capacity is 80% of the total lung capacity

Thus,

Hence, option B is correct

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
