Lobsters have an open circulatory system, where blood, known as hemolymph, flows freely through the body cavity rather than being confined to vessels. This system relies on a heart that pumps hemolymph into sinuses, surrounding the organs and tissues, allowing for nutrient and gas exchange. The hemolymph then returns to the heart through openings called ostia. This type of circulatory system is typical in many arthropods and provides sufficient circulation for their needs.
