The different organs associated with this system in humans include the heart, lungs, blood vessels, capillaries and blood. The heart is the pumping organ that squirts blood out. The heart does this with so much pressure that it can squirt blood to a height of up to 9 meters. It never stops and continually beats so blood is able to travel to all parts of the body.
Your blood transports oxygen, carbon dioxide, digested food, hormones and even waste products through these blood vessels.
Blood is a major connective tissue to the fluid. It is composed primarily of plasma and blood cells. There are three blood cell types, namely red blood cells, white blood cells, and platelets in the blood. The RBC's have haemoglobin, a complex protein that contains iron. The WBCs are the cells that help with disease fighting and attack any foreign bodies in the blood. The blood platelets are the ones that help blood clotting.

There is a phenomenon occurring in human beings called double circulation which is an efficient way. The heart pumps the blood, and travels to different organs through the different blood vessels and then returns to the heart again. Now, this blood flow in humans takes place in two ways, called the pulmonary pathway and the systemic pathway.
This system ensures the deoxygenated blood (blood containing carbon dioxide) from the right side of the heart goes into the lungs where gaseous exchange takes place. Blood gets filled with lung oxygen, and carbon dioxide is supplied to the lungs (from where it exits the body). The oxygenated blood then travels to all other parts of the body from the left side of the heart.
The double circulation seen here ensures that oxygenated blood and deoxygenated blood don't mix. The body cells also have an efficient supply of oxygen, and a higher rate of blood flow in the body.

A muscular, four - chambered organ, the human heart is. The two upper chambers called the right atrium and the left atrium, and the two lower chambers called ventricles from left and right. The right atrium and the right ventricle can together be called the right heart. Together the left atrium with the left ventricle can be called the left heart. Both heart chambers are divided from each other by muscular walls called septum.
The principal vessels of the blood are the arteries and veins. These are linked by a network of smaller, capillary vessels. Veins carry deoxygenated blood to the right side of the heart while arteries carry oxygenated blood to different parts of the body away from the heart.
The lymphatic system functions as a subsystem of the circulatory system in humans and in vertebrates. It has a role to play in human transportation, too. Lymph is a special fluid called a fluid in the tissue. It plays a role in the nutrient and gaseous exchange process that occurs via blood. Any residual excess fluid in the cells and tissues is absorbed by the lymph and drained into the blood-carrying venes.
Q1. What is the Main Pump of the Circulatory System?
Answer: As the heart beats, blood is pumped through a blood vessel system, called the circulatory system. The vessels are elastic, muscle tubes which carry blood to all parts of the body.
Q2. How does the Heart Function in the Circulatory System?
Answer: Your cardiovascular system is composed of the heart and circulatory system. Your heart functions as a pump which pushes blood to your body's organs, tissues, and cells. Blood supplies every cell with oxygen and nutrients and removes the carbon dioxide and waste products produced by those cells.
Q3. Is Your Heart in the Circulatory System?
Answer: It's a pump to your heart. It's a muscular organ about the size of your fist and is slightly left in your chest from the centre. Your heart and blood vessels together make up your cardiovascular system, circulating blood and oxygen all around your body.
Q4. Explain the 5 Major Parts of the Circulatory System?
Answer: Parts of the Circulatory system. The circulatory system is composed of the vessels of the heart, blood, blood vessels, lymph and lymph. While the heart is the circulatory system's only "organ," it is truly just a vessel surrounded by muscles. There are no standard organs to the circulatory system.
