FETAL PIG QUESTION!! 10 POiNTS RIGHT AWAY!!!?

Question

Why are veins generally not injected well with latex in a pig? What prevents the movement of latex through the vessels?

Answer 1

The cat is more anatomically acceptable to study anatomy in correlation to human anatomy and that is why cats are most often used for injection of red and blue latex to map arteries and veins, respectively. If in fact pig veins aren't generally injected, maybe it is due to this fact alone. Or, perhaps pigs blood vessels are not ideal to map artery and veins because they are too thin to withstand the viscosity of latex.

Answer 2

i will help with some of them 1) wear gloves because the specimen was in formaldehyde for preservation and formaldehyde is poisonous. 2) look up the function on the internet. any site you click regarding liver will tell you. its so large because we only have 1 liver, not 2 so it has to do all the work that a liver does and therefore it has to be large. you might get this idea better if you knew that if you take 1 kidney out, the remaining kidney grows larger as compensation. so 1 large liver is needed since we dont have 2! 3) look it up 4) small intestines are long because food absorption takes place there and the larger the surface area, the more absorption 5) i dont know, its complicated 6) look it up 7) its better than dissecting a rat for example because its larger. other reasons why it may be used is because its not endangered. i dont know, maybe they are similar because of evolution 8) we are different because we are not the same species...i really dont know i mean you can list a ton of differences, but we are also similar because of evolution. 10) my guess is the abdomen contains a lot of important organs. thats why the stomach and chest area which includes the abdomen is called the core of the body. so an incision made in the back is safer because you wont damage many organs that way.

Answer 3

The latex is not injected while the fetal pig is alive. Therefore the heart can not pump it throughout the body. Even if it got through the arteries, it would not get through the capillaries to the veins.
If the veins themselves are injected, they have valves to prevent back flow of blood.
