The present research is to be related with the students of the undergraduate study of University of Mosul college of Physical Education and Sports sciences. The study has been conducted during September, 2025 in the Animal Physiology Lab. The total number of the subjects of the study was 107 female and 68 male students aged between 18-21 years, enrolled in undergraduate course. Students blood typing and association with hemostatic parameters, such as bleeding and clotting time were studied. In both sexes blood-group typing was performed and bleeding time (BT) and clotting time (CT) were determined. Results of the study showed that the blood group B was the commonest blood group. The ABO blood groups are as follows: The bleeding and clotting time of O blood group is the longest. Based on the above data, it may be inferred that there could be a correlation between the two blood groups ABO and the above two tests (bleeding time and clotting time) in the study population.
