5. Phylum Chordata (vertebrates) have so much diversity that it must be split into three subphyla.
Match the following:
____contains those creatures that have a notochord through larva stage but then the notochord actually disappears in the adult stage.
____holds those organisms that have notochords throughout their entire lives.
____is made up of those vertebrates that have a notochord during their early development, but it turns into a true backbone before the animals are born or hatched. This group is usually referred to as “vertebrates.”
A. Subphylum Urochordata
B. Subphylum Cephalochordata
C. Subphylum Verterbrata

12. Circulation of Blood

13. Basic Circulatory System Figure 13.11

14. Figure 13.11 How many chambers does a fish have?
Atrium: A heart chamber that receives blood from veins that is carried back to the heart.
Ventricle: A heart chamber from which Oxygenated blood is pumped out.

15. From the heart chamber from which Oxygenated blood is pumped out  through the ventral aorta  Afferent brachial  capillaries in the gills where the blood releases CO2 --> water pours over the gills and Oxygen is then received into the blood. It leaves the gills through efferent brachial arteries. These arteries dump blood into the dorsal aorta. Some of the blood goes to the brain and other cells in the head supplying them with nutrients and oxygen. Now the blood is oxygen poor and is carried back to the hear in the anterior cardinal vein.
