20
Q

Gill Rakers

A

Protect the gills. Filtering extensions

21
Q

pyloric ceca

A

These appendages, secrete enzymes and provide additional digestive areas to the intestine.

22
Q

Proventriculus

A

Secretes an acidic/enzymatic mixture for mechanical digestion

23
Q

What are the non-vesseled organs?

A

The Spleen and the heart.

24
Q

What veins form the Sinus Venosus?

A

2 anterior vena cavae and one posterior vena cava

25
Posterior Vena Cava does what?
passes through the liver and send blood to the right atrium via the sinus venosus.
26
What is the pulmocutaneous arch?
Sends Oxygen poor blood to the skin and lungs
27
Carotid arch
