Epiglottis is the cartilage at the root of the tongue which moves to block the windpipe when food is swallowed, so that the food does not go down the trachea.
Although enzymatic action begins in the mouth, the major processes of digestion do not occur until the food passes down through the oesophagus into the stomach.
The heart develops electric charges as it beats because, like all muscles, it is electrically negative in its contracting portion and electrically positive in its relaxed portion.
The pulse becomes less and less intense as it passes through the small arteries until it becomes almost absent in the capillaries.
Once oxygen has diffused from the alveoli into the pulmonary blood, it is transpor ted to the tissue capillaries where it is released for use by the cells.
As vitamins are concerned with metabolism, it follows that absence or deficiency of certain vitamins can result in malnutrition and specific deficiency diseases.

9. Hydrochloric acid is a natural element in the stomach, and excess levels of it, together with the enzyme pepsin, quickly produce ulceration unless the stomach wall is protected.
Little is known about the physiological activity of vitamin E, but animal experi ments suggest that it is concerned with the reproductive cycle and fertility.
