Leeches has a closed circulatory system just like other animals. They usually circulate foods and gases through the coelomic fluids in their bodies.Ê
All bird species have different circulatory systems, for the most part the smaller species have an open system, while larger birds have a closed system.
Tigers are mammals and so their circulatory system is very similar to that of humans.
Even if insects have an open circulatory system, which is usually characterized by slow animals with low metabolic rates, their circulatory system does not participate in supplication of oxygen to the tissues and in the gas exchange process. That is handled by the independent tracheal system, the spiracles, which allows direct contact of cells with the air. With this, the oxygen demand can be supplied even with an open circulatory system.source: http://www.biology-questions-and-answers.com/the-circulatory-system.html
