The heart and the lungs are the primary organs of the circulatory system. The lungs are responsible for adding oxygen to blood. This oxygen-rich blood is then pumped to the heart, which then circulates it through the arteries to all the tissues throughout the body. Veins then return the blood for the addition of new oxygen and recirculation.Know More
Blood circulates through two bodily systems: the systemic and the pulmonary circulatory systems. The systemic circulatory system is the system that transports the blood from the heart to the other organs and tissues in the body. The human heart is made of four separate chambers. The two top chambers allow blood to enter the heart, while the two lower chambers allow blood to leave the heart. The heart receives signals from the body telling it how much blood to pump.
The pulmonary circulatory system consists of a short loop that circulates the blood from the lungs to the heart. Without this connection, the heart would not be able to pump out blood containing the oxygen needed by the other parts of the body. Oxygenation of the blood occurs in the lungs, with oxygen attaching itself to the hemoglobin in the red blood cells.Learn more about Organs
The main function of the circulatory system is transporting blood, oxygen, hormones, nutrients and other important substances throughout the body. The circulatory system is actually two separate systems of circulation, pulmonary and systemic, both of which interact with the heart and cardiovascular system to pump blood throughout that system.Full Answer >
The circulatory system is important because it is transports blood and other materials throughout the body. Without the circulatory system, the body does not receive oxygen, and the heart and lungs fail to work.Full Answer >
The major organs of the respiratory system are the lungs, trachea, bronchi and diaphragm. The respiratory system works together with the cardiovascular system to deliver oxygen to the organs and with the autonomic nervous system to regulate breathing.Full Answer >
The digestive system involves the mouth, throat, esophagus, stomach, small intestine, large intestine, pancreas, liver and gallbladder. The main organs involved in digestion include the esophagus, stomach, and the small and large intestines.Full Answer >
