Tendon a cord or band of dense, tough, inelastic, white, fibrous tissue, serving to connect a muscle with a bone or part; sinew.
red marrow of or relating to the heart:
yellow marrow bone marrow in which the stroma of the reticular network are largely filled primarily with fat; it replaces red marrow in the long bones after the fifth year of life.
skeletal muscle A muscle that is connected at either or both extremities with a bone and consists of elongated, multinucleated, transversely striated, skeletal muscle fibers, together with connective tissues, blood vessels, and nerves.
striated muscle muscle tissue in which the contractile fibrils in the cells are aligned in parallel bundles, so that their different regions form stripes visible in a microscope.
smooth muscle involuntary muscle tissue in the walls of viscera and blood vessels, consisting of nonstriated, spindle-shaped cells.
cardiac muscle the muscular tissue of the heart
intugumentary system The integumentary system is the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside.
epidermis the outermost living layer of an animal, usually composed of one or more layers of cells.
dermis the dense inner layer of skin beneath the epidermis, composed of connective tissue, blood and lymph vessels, sweat glands, hair follicles, and an elaborate sensory nerve network.
melanin any of a class of insoluble pigments, found in all forms of animal life, that account for the dark color of skin, hair, fur, scales, feathers, etc.
follicle a small cavity, sac, or gland.
mechincal digestion The process by which food is broken down into simple chemical compounds that can be absorbed and used as nutrients or eliminated by the body. In most animals, nutrients are obtained from food by the action of digestive enzymes.
chemical digestion The process by which food is converted into substances that can be absorbed and assimilated by a living organism. In most animals it is accomplished in the digestive tract by the mechanical and enzymatic breakdown of foods into simpler chemical enyzmes
epiglottis a thin, valvelike, cartilaginous structure that covers the glottis during swallowing, preventing the entrance of food and drink into the larynx.
perstalis the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wavelike movements that push the contents of the canal forward.
esphogaus a muscular passage connecting the mouth or pharynx with the stomach in invertebrate and vertebrate animals; gullet.
absorption uptake of substances by a tissue, as of nutrients through the wall of the intestine.
villus one of the minute, wormlike processes on certain membranes, especially on the mucous membrane of the small intestine, where they serve in absorbing nutriment.
pacemaker an electronic device implanted beneath the skin for providing a normal heartbeat by electrical stimulation of the heart muscle, used in certain heart conditions.
artery a blood vessel that conveys blood from the heart to any part of the body.
capillary one of the minute blood vessels between the terminations of the arteries and the beginnings of the veins.
vein one of the system of branching vessels or tubes conveying blood from various parts of the body to the heart.
plasma the liquid part of blood or lymph, as distinguished from the suspended elements.
red blood cells one of the cells of the blood, which in mammals are enucleate disks concave on both sides, contain hemoglobin, and carry oxygen to the cells and tissues and carbon dioxide back to the respiratory organs.
hemoglobin the oxygen-carrying pigment of red blood cells that gives them their red color and serves to convey oxygen to the tissues

platelet a small platelike body, especially a blood platelet.
lymph a clear yellowish, slightly alkaline, coagulable fluid, containing white blood cells in a liquid resembling blood plasma, that is derived from the tissues of the body and conveyed to the bloodstream by the lymphatic vessels.
lymph node any of the glandlike masses of tissue in the lymphatic vessels containing cells that become lymphocytes.
cilia minute hairlike organelles, identical in structure to flagella, that line the surfaces of certain cells and beat in rhythmic waves, providing locomotion to ciliate protozoans and moving liquids along internal epithelial tissue in animals.
pharynx the tube or cavity, with its surrounding membrane and muscles, that connects the mouth and nasal passages with the esophagus.
trachea the tube in humans and other air-breathing vertebrates extending from the larynx to the bronchi, serving as the principal passage for conveying air to and from the lungs; the windpipe.
alveoli an air cell of the lungs, formed by the terminal dilation of tiny air passageways.
diaphgram a muscular, membranous or ligamentous wall separating two cavities or limiting a cavity.
larynx a muscular and cartilaginous structure lined with mucous membrane at the upper part of the trachea in humans, in which the vocal cords are located.
excretion he substance excreted, as urine or sweat, or certain plant products.
