👉 Chirovascular system, or chirovascular network, is a type of blood circulation in mammals that allows for the exchange of oxygen and nutrients between the heart and the circulatory system. This network is composed of two main parts: the aorta (the longest artery in the body), which carries oxygen-rich blood to the rest of the body, and the carotid arteries (which carry oxygenated blood from the lungs to the rest of the body).
