The circulatory system pumps blood around the body, and the respiratory system facilitates the gas exchange that keeps the blood fresh. According to HowStuffWorks, the heart is connected to the lungs via the pulmonary arteries and veins.Know More
Oxygen-poor blood enters the heart through the right atrium. From there, according to HowStuffWorks, it flows through the tricuspid valve into the right ventricle. When the heart contracts during the diastolic phase, this blood is pumped out through the pulmonary arteries that run toward the lungs. At the lungs, the blood is circulated through a series of progressively smaller arterioles until it flows through capillaries lining the lungs' alveolar sacs. It is here that gas exchange takes place as oxygen is taken up by the blood, and carbon dioxide is released into the waste air.
After oxygenation, the fresh blood is circulated back through the bronchial veins and into the pulmonary veins. These run from the lungs and drain into the heart's left atrium. During the systolic phase of the heartbeat, the mitral valve under the left atrium opens and permits blood to pass into the left ventricle. This chamber is heavily muscled, according to HowStuffWorks, and it has the power to pump the oxygen-rich blood out through the aorta and into the rest of the body.Learn more about Human Anatomy
The urinary and circulatory systems work together mainly in the unit of the kidneys. The kidneys are a part of the urinary system, but they are also able to help regulate the circulatory system by filtering the blood and allowing it to become more regulated.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 main function of the circulatory system is to move blood and lymph through the body. Doing this transports nutrients and oxygen to the cells of the body and removes waste products such as carbon dioxide. The circulatory system is necessary to regulate temperature and pH balance and protect the body from diseases.Full Answer >
The respiratory system helps maintain homeostasis by regulating the intake of air into the body and by removing carbon dioxide from the blood, which in turn assists the circulatory system's function and many other operations in the body. Homeostasis is the overall equilibrium of the body's internal organs and functions. Without these internal systems being properly balanced it can lead to a number of issues in the human body, including death, depending on the severity of the imbalance.Full Answer >
