The human body as well as that of other animals (Species) is highly structured into organs and tissues which serve specific functions. Tissue is the organizational level intermediate between cells and organs system which compose the whole organism. All the tissues and cell types defined in an animal organism are hierarchical structured and shall be fully described. o

    head and neck Head and neck anatomy focuses on the structures of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat. It is an area frequently studied in depth by surgeons, dentists, dental technicians, and speech language pathologists [Wikipedia: http://en.wikipedia.org/wiki/Head_and_neck_anatomy].
    thorax 1: The part of the mammalian body between the neck and the abdomen; also: its cavity in which the heart and lungs lie.n2: The middle of the three chief divisions of the body of an insect; also: the corresponding part of a crustacean or an arachnid [Brenda].
    abdomen 1: The part of the body between the thorax and the pelvis; also: the cavity of this part of the trunk containing the chief viscera.n2: The posterior section of the body behind the thorax in an arthropod [Brenda].
    pelvis The inferior portion of the trunk of the body, bounded anteriorly and laterally by the two hip bones and posteriorly by the sacrum and coccyx. The pelvis is divided by a plane passing through the terminal lines into the pelvis major superiorly and the pelvis minor inferiorly [Brenda].
    perineum In human anatomy, the perineum (Late Latin, from Greek περίνεος - perineos) is a region of the body including the perineal body and surrounding structures. There is some variability in how the boundaries are defined, but the term generally includes the genitals and anus [Wikipedia: http://en.wikipedia.org/wiki/Perineum].
    upper limb The upper limb or upper extremity is the region in an animal extending from the deltoid region to the hand, including the arm, axilla and shoulder [Wikipedia: http://en.wikipedia.org/wiki/Upper_limb].
    lower limb The lower limb is a limb of the body [Wikipedia: http://en.wikipedia.org/wiki/Lower_limb]. According to Terminologia Anatomica, it includes the pelvic girdle, buttocks, hip, and thigh, as well as the components distal to the knee [Wikipedia: http://en.wikipedia.org/wiki/Lower_limb].
    whole body The main part of an animal body especially as distinguished from limbs and head [Brenda].
    heart 1: A hollow muscular organ of vertebrate animals that by its rhythmic contraction acts as a force pump maintaining the circulation of the blood.n2: A structure in an invertebrate animal functionally analogous to the vertebrate heart [Brenda].
    artery Any of the tubular branching muscular- and elastic-walled vessels that carry blood from the heart through the body [Brenda].
    vein Any of the tubular branching vessels that carry blood from the capillaries toward the heart [Brenda].
    capillary A capillary tube; especially: any of the smallest blood vessels connecting arterioles with venules and forming networks throughout the body [Brenda].
    nose 1a: The part of the face that bears the nostrils and covers the anterior part of the nasal cavity; broadly: this part together with the nasal cavity.n1b: The anterior part of the head at the top or end of the muzzle: snout, proboscis.n2: The vertebrate olfactory organ [Brenda].
    sinus Sinus is a sack or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue. In common usage, "sinus" usually refers to the paranasal sinuses, which are air cavities in the cranial bones, especially those near the nose and connecting to it. Each individual has four paired cavities located in the cranial bone or skull. These cavities are vital for a number of reasons [Wikipedia: http://en.wikipedia.org/wiki/Sinus_(anatomy)].
    larynx The modified upper part of the trachea of air-breathing vertebrates that in humans, most other mammals, and a few lower forms contains the vocal cords [Brenda].
    trachea 1: The cartilaginous and membranous tube descending from the larynx and branching into the right and left main bronchi. It is kept patent by a series of about twenty transverse horseshoe-shaped cartilages. Called also windpipe.n2: One of a system of minute tubes ramifying throughout the body of a terrestrial arthropod and delivering air to the tissues. Called also tracheal tubule [Brenda].
    bronchus Either of the two primary divisions of the trachea that lead respectively into the right and the left lung [Brenda].
    lung One of the usually paired compound saccular thoracic organs that constitute the basic respiratory organ of air-breathing vertebrates [Brenda].
    pleura The delicate serous membrane that lines each half of the thorax of mammals and is folded back over the surface of the lung of the same side [Brenda].
    bone marrow The soft, fatty, vascular tissue that fills most bone cavities and is the source of red blood cells and many white blood cells [Brenda].
    blood 1: The fluid that circulates in the heart, arteries, capillaries, and veins of a vertebrate animal carrying nourishment and oxygen to and bringing away waste products from all parts of the body.n2: A comparable fluid of an invertebrate [Brenda].
    lymph A clear, watery, sometimes faintly yellowish fluid derived from body tissues that contains white blood cells and circulates throughout the lymphatic system, returning to the venous bloodstream through the thoracic duct. Lymph acts to remove bacteria and certain proteins from the tissues, transport fat from the small intestine, and supply mature lymphocytes to the blood [Brenda].
    lymph node Any of the rounded masses of lymphoid tissue that are surrounded by a capsule of connective tissue, are distributed along the lymphatic vessels, and contain numerous lymphocytes which filter the flow of lymph [Brenda].
    tonsil The human palatine tonsils and the nasopharyngeal tonsil are lymphoepithelial tissues located in strategic areas of the oropharynx and nasopharynx, although most commonly, the term tonsils refers to the palatine tonsils that can be seen in the back of the throat [Brenda]. faucial tonsil
    spleen A highly vascular ductless organ that is located in the left abdominal region near the stomach or intestine of most vertebrates and is concerned with final destruction of red blood cells, filtration and storage of blood, and production of lymphocytes [Brenda].
