Jacques had her FINAL checkup with the doctor today, and he feels she's completely cured of her pneumonia!!!

@Markw84 We got to talking about antibiotic injections and I learned something new. He said that it has been discovered that most reptiles have "Renal-Portal Systemic Circulation." This means that blood goes to the kidneys, then directly to the liver and anything filtered out is then expelled.
SO if a turtle gets an injection in the BACK HALF of their body (between the heart and the tail), whatever antibiotic was injected goes to the kidneys, then the liver THEN IS EXPELLED. It NEVER REACHES THE LUNGS OR THE HEAD or anywhere on the front half of the animal!!!! Injections in the back half are useless for infections in the lungs, head, mouth etc.

When you give an antibiotic injection in the FRONT HALF of the animal (between the heart and the nose) then the antibiotic circulates all through the body, including the lungs, before finally circulating through the kidneys, liver and then gone. All of Jacques' injections were given in her shoulder muscles.

They originally thought that ALL reptiles had this circulation but some do not- he couldn't remember if it was lizards or some type of terrapin.

Yes, chelonians are amazingly adapted animals. They also have a 3 chambered heart instead of 4 chambered like mammals and crocodiles. That combines with two aortas that they use to totally shut blood flow from the lungs when they stop breathing. With aquatics that is when they dive, but tortoises retain this ability. So when they shut down their metabolism, the blood flow is changed.

The renal portal system does indeed funnel blood flow form the back half of the body through the kidneys before going back to the heart. So this does mean any medication injected in the lower body will be filtered by the kidney before it reaches the heart, and then, the rest of the body. That does not mean it will never reach the rest of the body. But studies have shown it is definitely reduced in strength and much less effective. This also produces a greater stress on the kidneys if injections are made in the lower body.
