The heart and all the arteries and veins, and the lungs make up the circulatory system.
The heart pumps oxygenated blood around the body through the aorta, and deoxygenated blood returns to the heart through the vena cava. This is the systemic circuit.
At the lungs, small air sacs called alveoli allow oxygen to diffuse into the arteries before going to the heart, and then being pumped around the rest of the body. This is the pulmonary circuit.
The circulatory system
The circulatory system works with digestive system to circulate the nutrients to all the body parts. The nutrients are digested and absorbed by the digestive system. The circulatory system circulates the nutrients throughout the body.

It would take a textbook to cover all of the parts of the human body. In this could include the skin, the muscles, the nervous system, the digestive system, the circulatory system, hormones, the urinary system plus many more.
There is definitely a general need for a circulatory system. This system carries blood, oxygen, and nutrients to all parts of the body.
The circulatory system and respiratory system are interlaced. The circulatory system much deliver nutrients to all the parts of the body. Every single part of the body needs oxygen, so the circulatory system takes the oxygen collected by the respiratory system and delivers it to the rest of the body.
The circulatory system consists of the heart, veins, arteries, vessels and capillaries that provide pathways for the blood to reach all parts of the body.
