Already the Babylonians connected this Zodiac sign and the constellation with the mythological animal, sort of a mermaid goat. They called it the Goat-Fish. The reason for this is hidden in history.
Without an adequate blood supply, the heart muscle is deprived of oxygen and nutrients and waste products manufactured by the cells accumulates in the muscle tissue. Depending on the severity, it may cause myocardial ischemia, which is damage but not death of the muscle due to an inadequate blood supply. Alternatively it may cause death of the muscle tissue which is known as a myocardial infarction (MI).
Tissues vary considerably in their sensitivity to hypoxia. Neurological cells tolerate hypoxia for only a few minutes. whereas bladder smooth muscle may survive for several days. without oxygen. This has important implications in the. management of oxygen transport and monitoring of tissue. hypoxia in critically ill patients. Oxygen transport. Delivery to organs and tissues. The mechanisms controlling oxygen distribution are. incompletely understood but involve a series of convective and. diffusive processes.
