Functions of Organs

Here are the Functions

  1. Gall bladder-Bile from the liver is stored here.
  2. Heart-Functions the same as a humans, it pumps blood throughout the shark's body. Is made up of many cavities like the atrium and sinus venosus.
  3. Kidney- Produces Urine
  4. Liver-Two main functions: To store all fatty reserves and energy. It also has many oils in it to help keep the shark buoyant.
  5. Pancreas-It is a digestive gland. It produces hormones as well as digestive enzymes to help break down fats and carbs in the stomach.
  6. Small Intestines- where the food is broken down at.
  7. Large Intestines- where chyme turns in to waste
  8. Stomach-Food goes here after being devoured, and digestion takes place here.
  9. Esophagus- connection between the pharynx to the stomach. Sends food
  10. Rectum-Where excretory matter is stored right before disposal.
  11. Clappers-A finger-like extension of the male reproductive system that aid in sperm
  12. Lateral line- It is a pale line that extends the length of the shark, but the line is actually a group of tiny pores that open into the canal. Then water travels through the canal and allows the shark to control water movement.
  13. Gills- five vertical slits that allow water to exit the mouth after passing over the
