On July 16, 1798, President John Adams signed the first Federal public health law, "An act for the relief of sick and disabled Seamen." This assessed every seaman at American ports 20 cents a month. This was the first prepaid medical care plan in the United States. The monies were used for the care of sick seamen and the building of seamen's hospitals. This act created the Marine Hospital Service under the Department of the Treasury. In 1802 Marine Hospitals were operating in Boston; Newport; Norfolk; and Charleston, S.C. and medical services were contracted in other ports
Answer: The squamous epithelial layer of tissues forms an important layer that lines the organs in the human or animal body.
