Thoracic cavity- Region most cranial of coelom. Separated from caudal by diaphragmn Coelom- contains digestive tract and other internal orgs. Formed between layers of mesoderm Abdominal- Most caudal. Opposite of Thoracic Pleural cavities- Lungs Pericardial- heart

Cerebellum- the part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity. Cerebral Hemisphere- each of the two parts of the cerebrum (left and right) in the brain of a vertebrate. Liver- liver detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. Trachea- Anterior - a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.

Spleen- an abdominal organ involved in the production and removal of blood cells in most vertebrates and forming part of the immune system. Cecum- a pouch connected to the junction of the small and large intestines breaks down cellulose, ingest feces for copography Stomach- the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine. Kidney- The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Everyday, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid Abdominal Aorta- abdominal aorta is the largest artery in the abdomen that provides blood to the organs and tissues of the abdomen , pelvis, and legs. It descends from the thorax as a continuation of the thoracic aorta and branches several times to form the major arteries of the abdomen . Urinary bladder- Collects urine that is excreted and filtered by kidneys Uterus- the organ in the lower body of a woman or female mammal where offspring are conceived and in which they gestate before birth; the womb. Fallopian Tubes- in a female mammal) either of a pair of tubes along which eggs travel from the ovaries to the uterus. Ovary- Posterior, Produces eggs for reproduction Arteries- Stained with red dye Veins- stained with blue dye Lab 7: Animal Development Biologist use model organisms to study development. Sea urchin (Echinodermata) External fertilization 2 haploid gametes= diploid zygotes Form fertilization membrane- block polyspermy, Outermost ring

Embryos and Development -cells formed from the division (cleavage) of the zygote differentiate Sea Urchin -embryo is transparent -graze on algae -male and female shed gametes into open sea (fertilization external) Major stages in animal embryonic development 1. F
