The spheres are merely there to show (to yourself and your visitors) that your dragons are higher than level ten. The shrines will show that your dragons are able to level past ten (or fifteen if it's gold), but the orbs show for each particular dragon that is above level 10.
Hemoglobin is what actually gives your red blood cells the ability to carry oxygen. A high hematocrit simply means that you have a higher concentration of hemoglobin in the blood. First of all, it could indicate dehydration, or normal amount of hemoglobin, but too little blood (plasma) volume. If this is the case, depending on how high the hematocrit is, rehydration might be needed.
True False. Because the hematocrit is a percentage of red blood cells, as compared to the total volume of blood, any increase or decrease in plasma volume affects the hematocrit. A patient with a severe burn loses huge amounts of plasma from damaged capillaries. decreased hematocrit occurs due to overhydration, which lowers the percentage of red blood cells in relation to the liquid plasma portion of blood. A hematocrit is frequently done to assess the extent of significant blood loss.
