A goat's circulatory system is much like that of the human. It has a heart, and blood vessels, etc. to circulate blood.
Their circulartion system is very similar to humans (closed circulatory system)
A Strange but interesting one From Anonymous
Animals that breathe using lungs have a pulmonary circulatory system. In this system, the lungs are dependent on the flow of blood from the systemic circulatory system, which works in tandem with the pulmonary system to provide blood flow to these vital organs.
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
I think is because the circulatory system of a reptile has the ability to redirect deoxygenated blood from the lungs to save energy.
The circulatory system found in a goat is the one known as the open circulatory system. This is the common type of circulatory system that you will find in most mammals.
