The circulatory system is comprised of the cardiovascular system and the lymphatic system. It is the lymphatic system and its network of lymphatic capillaries, lymph nodes, thymus gland. and the spleen that make up our immune system. It protects the body from pathogens; bacteria, viruses, and fungi.

The cardiovascular system and the circulatory system are the same. They consist of the heart, veins, blood vessels, arteries and blood supply.
yes
because they supply blood to the body
They supply the heart with the necessary oxygen it needs.
The defenses of the body, including the skin, immune system, digestive system, and circulatory system, are collectively referred to as the "immune system" or "defense systems." The skin acts as a physical barrier, while the immune system provides a complex network of cells and proteins that identify and eliminate pathogens. The digestive system also plays a role by using enzymes and acids to neutralize harmful microorganisms, and the circulatory system helps transport immune cells throughout the body. Together, these systems work in concert to protect the body from infections and diseases.
Yes,the circulatory system acts as the transport system that moves the blood throughout the body. It provides a continuous supply of fresh blood.
closed circulatory system (double circulatory system)
No, the circulatory system is not the last line of defense against infection. The immune system plays the primary role in defending the body against infections. The circulatory system helps in distributing immune cells and antibodies throughout the body to fight off infections, but it is not the final line of defense.
The organs of the circulatory system include the heart, blood, and blood vessels. The heart is the pump that takes the oxygenated blood through the blood vessels to supply the cells with energy.
The systemic circulatory system doesn't deliver blood to the lungs because they are already well oxygenated and receive their other nutrients via the pulmonary circuit.
