I did this quiz twice this morning. The first just using memory and my general understanding of physiology and anatomy (mostly in the area of farm animals) the second time I used the web (whatever did we do without the WWW?) I provided links to the websites I took info from (I know this is not the proper way to cite sources but I was being lazy, much easier to just copy and paste the link)
Here are my results:
Without books or web
1. How does a marine fish make its blood?
Bone marrow produces blood cells
2. Name all the functions of a marine fish's gills?
Absorbing oxygen from the water
3. How many kidneys does a fish have? What is the function of the marine fish kidney(s)?
Two, Removing toxins from the blood
4. Describe what the marine fish stomach looks like.
5. The swim bladder is known to help the fish stabilize itself in the water. What gas is in the swim bladder?
Nitrogen
6. How many lymph glands does a marine fish have?
7. Name all the functions of the fish mucous coating you can.
Protects the fish’s skin, prevent absorption of toxins through the skin, resist parasites
8. What does a Tang eat?
Mostly Algea, 75% vegetable matter, 25% meat
9. When a fish is 'piping' what is it doing? Name the primary cause(s) for a marine fish to do this.
10 When a marine fish is under stress, does the blood count go up or down
White cell count up

The skeleton is the site of red blood cell production

2. Name all the functions of a marine fish's gills?
Respiration “As water flows across the gills, the oxygen within them diffuses into blood circulating through vessels in the filaments and lamellae. Simultaneously, carbon dioxide in the fish's bloodstream diffuses into the water and is carried out of the body.â€
http://www.kwic.com/~pagodavista/schoolhouse/species/fish/fishgill.htm
“Fish gills are a pretty complex structure, and are very well adapted to getting oxygen out of water. Gills are made up of filaments (the feathery red things) attached to a rigid gill arch. The arches are hollow and have arteries inside them that contain blood low in oxygen. These arteries branch into smaller arterioles that run inside the filaments. Each flat filament has many tiny folds on it (called lamellae) to increase surface area. In fast moving fish, the surface area of the gills may be ten times that of the actual animal. Tiny capillaries branch off of the arterioles and carry the blood close to the inner surface of the lamellae. Because the oxygen concentration is less in the blood than in the water flowing over the gills, the oxygen from the water naturally diffuses into the blood.
There is an adaptation that fish have to maximize the flow of oxygen into the blood called countercurrent exchange. This is when the water flowing over the lamellae is in the opposite direction as the blood flowing through the capillaries. In this way, the concentration of oxygen in the blood as it moves through the capillaries is always lower than the water, and oxygen will diffuse over the whole length of the lamellae.
Once the blood is fully oxygenated from it's trip through the gills, it is pumped back into the body and used by the fish for energy, filling the float bladder, and for nearly all of the metabolic processes in the fishes' body.â€

3. How many kidneys does a fish have? What is the function of the marine fish kidney(s)?
The fish has one kidney. Filters liquid waste, regulates water and salt concentrations in the fish’s body

4. Describe what the marine fish stomach looks like.
Usually the stomach is a bent muscular tube in a "U" or "V" shape

5. The swim bladder is known to help the fish stabilize itself in the water. What gas is in the swim bladder?
oxygen, carbon dioxide, and nitrogen

6. How many lymph glands does a marine fish have?
Fish do not have lymph nodes

7. Name all the functions of the fish mucous coating you can.
“the fish coating (some call it a mucous, others a slime) contains bactericide and antibodies to pathogens as well as resisters to opportunistic organisms (e.g., fungus and molds).â€

8. What does a Tang eat?
The Tang is a Herbivore “Herbivores
This fish expects less than 35% whole marine animals and the balance vegetables. Generally, the older the fish the more it relies on vegetables. So the 35% number should decrease as the fish matures.

9. When a fish is 'piping' what is it doing? Name the primary cause(s) for a marine fish to do this.
“Piping:
This is the gulping of air at the surface of the water. It is indicative of severe hypoxia. . . Hypoxic animals typically act very anxious and are not concerned with other things going on around them. Piping may be secondary to low oxygen levels or to gill parasites.â€

10. When a marine fish is under stress, does the blood count go up or down
It goes up: Reserves of red blood cells are released into the bloodstream
