The normal heart has low pyruvic acid to lactic acid ratio which shows the heart is working properly and has no problem in it.
The heart with low pyruvic acid to lactic acid ratio shows that it has some respiratory problem and does not have adequate oxygen supply.
Even the person having very low pyruvic acid to lactic acid ratio shows respiratory problem.
Cardiac Output. Cardiac Output (CO) is the amount of blood pumped by the heart per unit of time and it depends on 2 important variables like below, Stroke Volume (SV) = the amount of blood ejected per beat of the heart (Normally, 70 ml/beat).

All living organisms are composed of one or more cells (according to the cell theory) and viruses do not have cells. Therefore, many scientists classify viruses as non-living.
Viruses are non-cellular microscopic infectious organism that are composed of two main parts; nucleic acid (DNA or RNA) and a protein coat that protects the nucleic acid. Viruses require a living cell (host) to reproduce and usually cause disease in the host organism.
