Freshwater Fish Internal Organs Mr. Berry
Internal Anatomy http://myfwc.com/Fishing/Fishes/anatomy.html#internal
You will be responsible for: • Muscle • Kidney • Pyloric Caeca • Spine • Spinal Cord • Swim Bladder • Stomach • Intestines • Heart • Liver • Vent
For the Test • Correctly label all internal parts • Be able to explain the function of each part http://myfwc.com/Fishing/Fishes/panfish.html
Muscle • Provides movement • This portion is usually consumed as the fillet
Kidney • Filters waste materials from the blood • Regulates water and salt concentrations in the body
Pyloric Caeca • Secretes enzymes that help digest food • Is Identified by it’s finger-like projections next to the stomach
Spinal Cord • Connects brain to rest of body • Relays information from the brain to the rest of the body
Spine • Primary backbone of the fish • Made up of vertebrae that protect the spinal cord
Swim Bladder • An air filled organ • Allows fish to suspend neutrally in the water • Conserves energy instead of constant swimming
Liver • Very Important Organ • Secretes enzymes to aid in digestion • Stores fats and carbohydrates • Moderates the blood chemistry (nitrogen excretion)
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!
Vent • Site of waste elimination from the body
Heart • Circulates blood throughout the body • Oxygen and digested nutrients are delivered to cells throughout the body by the circulated blood
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
