What happens when animal blood is put into physiologic saline?

When animal blood is put into physiologic saline, the red blood cells will lyse (rupture) and release their hemoglobin. This is because the saline solution is hypotonic to the red blood cells, meaning that it has a lower concentration of solutes than the cells. As a result, water will move into the cells, causing them to swell and eventually burst.

The release of hemoglobin from the red blood cells can cause a number of problems, including:

* Hemoglobinuria: This is the presence of hemoglobin in the urine. It can occur when the kidneys are unable to filter out the hemoglobin that has been released from the red blood cells. Hemoglobinuria can lead to kidney damage and failure.

* Methemoglobinemia: This is a condition in which the hemoglobin in the blood is converted to methemoglobin, which cannot carry oxygen. Methemoglobinemia can lead to cyanosis (a bluish discoloration of the skin), shortness of breath, and dizziness.

* Hemolytic anemia: This is a condition in which the red blood cells are destroyed faster than they can be replaced. Hemolytic anemia can lead to fatigue, weakness, and shortness of breath.

In severe cases, animal blood put into physiologic saline can lead to death.
