In this article we explore the relationship between systole and diameter of closed hyperbolic orientable surfaces. We show that they satisfy a certain inequality, which can be used to deduce their ratio has (genus dependent) upper bound.

128 human hearts including 70 males and 58 females in all age groups were used for the present study. Coronary arteries dissected out from hearts. The luminal diameter was studied four major coronary arteries, namely, right artery (RCA), left (LCA), anterior descending (LAD) circumflex (LCX) both sexes. histological sections stained with H & E stain measured help of ocular micrometer.
