How Does Calcium Affect the Heart? | Healthfully
During electrical conductivity, calcium is released from the sarcoplasmic reticulum, a structure found inside muscle fibers, and helps your heart beat and contract properly. Any disruption in the release of calcium from the sarcoplasmic reticulum can impair heart function, according to research reported in the March 2003 issue of the “Journal of Clinical Investigation.
Calcium metal was not available in large scale until the beginning of the 20th century. Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same coination of these atoms.
