1. Freshwater Fish Internal Organs Mr. Berry

2. Internal Anatomy http://myfwc.com/Fishing/Fishes/an atomy.html#internal

3. You will be responsible for: Muscle Kidney Pyloric Caeca Spine Spinal Cord Swim Bladder Stomach Intestines Heart Liver Vent

4. For the Test Correctly label all internal parts Be able to explain the function of each part http://myfwc.com/Fishing/Fishe s/panfish.html

5. Muscle Provides movement This portion is usually consumed as the fillet

6. Kidney Filters waste materials from the blood Regulates water and salt concentrations in the body

7. Pyloric Caeca Secretes enzymes that help digest food Is Identified by it’s finger-like projections next to the stomach

8. Spinal Cord Connects brain to rest of body Relays information from the brain to the rest of the body

9. Spine Primary backbone of the fish Made up of vertebrae that protect the spinal cord

10. Swim Bladder An air filled organ Allows fish to suspend neutrally in the water Conserves energy instead of constant swimming

11. Liver Very Important Organ Secretes enzymes to aid in digestion Stores fats and carbohydrates Moderates the blood chemistry (nitrogen excretion)

12. Review: Be able to label all internal body parts and organs listed. Know function or key role played by each body part as listed in this lecture. Know those and you will do great!

13. Vent Site of waste elimination from the body

14. Heart Circulates blood throughout the body Oxygen and digested nutrients are delivered to cells throughout the body by the circulated blood

15. Stomach and Intestines Digest food Absorbs nutrients Carnivorous fish have shorter intestines than herbivores because plants are harder to digest. The longer intestine allows for more time and area to absorb nutrients
