Splenic contraction - ANS significant, allows horses to have more speed, rbc
stored here, circulate in spleen, cause fight or flight response, RBC can be
damaged here
RBC function - ANS transports O2 from the lungs to the tissues and carbon
dioxide from tissues to lungs
hemoglobin - ANS iron-containing protein in red blood cells that carries oxygen
for delivery to cells
