Final answer:
The circulatory system is vital for the distribution of essential substances within organisms. Closed circulatory systems, with separate blood and interstitial fluid, are found in vertebrates and vary from two-chambered to four-chambered hearts. In contrast, open circulatory systems, utilized by many invertebrates, involve hemolymph mixing with body fluids in an open body cavity. the correct option is C)Closed circulatory system.
Step-by-step explanation:
Exploring the Types of Circulatory Systems:
The circulatory system plays a crucial role in transporting gases, nutrients, and wastes throughout the body. A closed circulatory system is characterized by blood being pumped through vessels that are distinctly separate from the interstitial fluid. This type of system is found in most vertebrates including humans.
For instance, fish possess a two-chambered heart, amphibians and most non-avian reptiles have a three-chambered heart with some mixing of blood, and mammals and birds boast a four-chambered heart that prevents any mixing of oxygen-rich and oxygen-poor blood, allowing for efficient double circulation. In contrast, an open circulatory system consists of hemolymph being pumped through vessels that open into the body cavity, returning through openings called ostia. Many invertebrates, such as arthropods and mollusks, utilize this open system.
