Weopened the fish’s stomach to see its digestive and circulatory system. To see how the digestive and circulatory systems work inside of a fish and how it looks like.

Theory: The fish are aquatic vertebrates usually ectodermic, most of them covered with scales, and equipped with fins, which allow its movement in water and thegills, which capture the dissolved oxygen in the water. Fish are abundant in both saltwater and freshwater, being able to find species from mountain streams and Deep in Ocean. Foods prepared withfish are an important food source for humans. They can be caught from wild individuals, or similarly bred cattle. Today the fishing call each day becomes more popular as an activity. Fish have had a rolein many cultures throughout history, ranging from religious deities to subjects of books and movies. It has a closed circulatory system; it has a heart with two chambers. The heart pumps the blood tothe gills and the gills to the rest of its body and then it goes back to its heart.
Materials and methodology: the materials were a small knife, gloves, lab apron, science book, notebooks, tray, andmasks to cover your mouth. The methodology was: copy the instruction onto our notebook, read the steps on the book, cut the fish’s bottom part of its stomach, recognize the parts, take it to thecafeteria to be thrown away.
Results:

3. What is the role of the mouth and gills flap inbreathing?
Answers:
1. to move and swim
2. to balance its self, to contain air to not get tired while swimming, and to produce and receive sound
