Circulatory System of Perch
brain-main organ of the nervous system and is protected by the skull.
spinal cord-component of the nervous system made out of a soft fatty surface and forming a cylindrical stem inside the vertebral column.
stomach-receives food to be later digested.
fin-swimming appendages formed of a membrane and usually prickly rays located on the anterior dorsal part of the body, provides stability.
intestine-section of the digestive tract between the stomach and the anus where absorption of nutrients is carried out and waste is transformed to fecal matter.
lateral line-used to detect movements and vibration in water.
anus-terminal orifice for the digestive tract enabling ejection of fecal matter.
spleen-organ of the circulatory system were impurities in the blood are destroyed.
kidney-organ that eliminates metabolic wastes and maintains the pressure of internal fluids.
air bladder-flexible air-filled sac located above the viscera; it allows the fish to remain buoyant at a specific depth.
two chambered heart-muscular organ helping blood to circulate.
operculum-covers and protects the gills.
sex organs-in fish, females produce eggs in the ovaries and the male produces soft roe in the testes; the eggs and roe are expelled into the water, where fertilization occurs.
