The tunica media is the middle layer of the arteries and veins. It is comprised of smooth muscle and connective tissue.
What is Tunica media ?
The middle layer, or tunica, of an artery or vein is called the tunica media, or media for short. On the interior and outside, it is located between the tunica intima and the tunica externa.
Smooth muscle cells, elastin, and collagen make up tunica media. On the interior and outside, it is located between the tunica intima and the tunica externa.
By virtue of its color and the transverse arrangement of its fibers, the middle coat (tunica medium) may be separated from the inner (tunica intima). A thick layer of connective tissue containing elastic fibers, coupled with a transverse layer of muscle tissue in some veins, makes up the intermediate coat. In comparison to the arteries, the veins have a significant surplus of white fibrous material and a significantly lesser number of elastic fibers.

After an arduous sea voyage, immigrants arriving at Ellis Island were tagged with information from their ship's registry; they then waited on long lines for medical and legal inspections to determine if they were fit for entry into the United States.
From 1892 to 1924, Ellis Island was America's largest and most active immigration station, where over 12 million immigrants were processed. On average, the inspection process took approximately 3-7 hours.
More than 120,000 immigrants were sent back to their countries of origin, and during the island's half-century of operation more than 3,500 immigrants died there. Ellis Island waylaid certain arrivals, including those likely to become public charges, such as unescorted women and children.
