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

    fatbody 1. A food reserve of fatty tissue in the larval stages of certain insects. 2. A mass of fatty tissue located near the genital glands in some amphibians, including the frogs and toads.
    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].
    liver 1: A large very vascular glandular organ of vertebrates that secretes bile and causes important changes in many of the substances contained in the blood (as by converting sugars into glycogen which it stores up until required and by forming urea).n2: Any of various large compound glands associated with the digestive tract of invertebrate animals and probably concerned with the secretion of digestive enzymes [Brenda].
    hair 1: A slender threadlike outgrowth of the epidermis of an animal; especially: one of the usually pigmented filaments that form the characteristic coat of a mammal.n2: The hairy covering of an animal or a body part; especially: the coating of hairs on a human head [Brenda].
    kidney 1: One of a pair of vertebrate organs situated in the body cavity near the spinal column that excrete waste products of metabolism, in humans are bean-shaped organs about 4 1/2 inches (11 1/2 centimeters) long lying behind the peritoneum in a mass of fatty tissue, and consist chiefly of nephrons by which urine is secreted, collected, and discharged into a main cavity whence it is conveyed by the ureter to the bladder.n2: Any of various excretory organs of invertebrate animals [Brenda].
    tooth 1: One of the hard bony appendages that are borne on the jaws or in many of the lower vertebrates on other bones in the walls of the mouth or pharynx and serve especially for the prehension and mastication of food and as weapons of offense and defense.n2: Any of various usually hard and sharp processes especially about the mouth of an invertebrate [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].
    pericardium 1: The conical sac of serous membrane that encloses the heart and the roots of the great blood vessels of vertebrates.n2: A cavity or space that contains the heart of an invertebrate and in arthropods is a part of the hemocoel [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].
    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].
    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].
    brain 1: The portion of the vertebrate central nervous system that constitutes the organ of thought and neural coordination, includes all the higher nervous centers receiving stimuli from the sense organs and interpreting and correlating them to formulate the motor impulses, is made up of neurons and supporting and nutritive structures, is enclosed within the skull, and is continuous with the spinal cord through the foramen magnum. Also named encephalon.n2: A nervous center in invertebrates comparable in position and function to the vertebrate brain [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].
