Observation of anatomical structure of the right coronary artery ingoat heart

Objective To observe the anatomical structure of the right coronary artery of goat hearts and enrich experimental materials of animal. Methods The goat hearts were fixed with 10% formaldehyde, disse cted, performed with artery cast form to show the gross anatomical structure of the right coronary artery. The length of the right coronary artery and it′s bra nches were observed and measured.Results Coronary artery of goa t heart included the left coronary artery and the right one. The right one was t hicker,and had three branches, branch of atrium ,ventricular branch, artery of sinuatrial node. The ventricular branch of the right coronary artery slightly w ent down along the posterior interventricular groove. Conclusion Coronary artery of goat heart is similar to that of human.
