أقامت كلية الطب البيطري في جامعة القادسية تقيم حلقة نقاشية علمية بعنوان Blood circulation in bird وحاضر الحلقة أ.م . صفية كريم والي العمري .
تهدف الحلقة دراسة دوران الدم في الطيور.
تضمنت الحلقة : A simplified approach would be to view the blood system as a pipe-work of tubes, starting at the heart and branching off to enter and diffuse (getting smaller and smaller) into the tissue of organs. Inside the tissue they converge (come together again) to form veins that return the blood to the heart

- The heart pumps oxygen-containing blood (red blood vessels) to tissues of the various body parts where oxygen is given off and carbon dioxide picked up and blood returns to the heart.
- The carbon dioxide-containing blood (blue vessels) is pumped to the heart and lungs. Exchange of carbon dioxide for oxygen takes place and returns to the heart.
- Nutrients from digested feed is picked up in the digestive tract and transported to the liver and heart for distribution to body tissues.
- Transporting heat from inner organs to the skin. This is not illustrated in the illustration above but has already been discussed in an earlier chapter (If you are not sure, stop and read through the notes again). The rate of heat loss from the skin will obviously be determined by the difference in temperature of the body and the surrounding air.
