Such meat is called halal, or lawful. Namespaces Article Talk.

Modern mammals are readily differentiated from other animals by the following characteristics: hair; a four-chambered heart with the aorta descending on the left; red blood cells that lack a nucleus allowing for increased surface area for oxygen transport ; a muscular diaphragm separating the abdominal and thoracic cavities that aids in breathing; descent of the testes into a scrotum to achieve a temperature environment amenable to sperm development; a variety of skin glands including sebaceous, sweat, and milk or mammary the characteristic giving mammals their name ; and elaborate dermal musculature controlling the skin , particularly in the face associated with suckling in young.
