The heart works with the lungs to take oxygen to the farthest reaches of your body and exhale the carbon dioxide that has built up in the cells. This is all a seamless transportation system that happens without any thought at all on your part. Blood pressure - Arterial • Higher pressure, 90-100 mm Hg • Propels blood to all other tissues of the body (i.e., systemic circulation) - Venous • Lower pressure, 12 mm Hg • Propels blood through the lungs (i.e., pulmonary circulation) Your blood vessels might also constrict or expand, thus allowing more or less of the body's fluids to be lost through sweat. The cardiovascular system, also known as the circulatory system, includes the heart, arteries, veins, capillaries and blood. The heart has four chambers — two on top and two on bottom: The two bottom chambers are the right ventricle and the left ventricle. That blood travels through a complex system of arteries, veins and capillaries. The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive. The most important substance it brings to cells and tissues is oxygen from the lungs. Now, picture the small roads that branch off that major highway, the ones that lead to small town. The heart is the organ that supplies blood and oxygen to all parts of the body. The circulatory classification is individual of the numerous classifications in the bodies of different organisms. © 2020 Houghton Mifflin Harcourt. The nervous and digestive systems work closely with the cardiovascular system. This system contains two fluids, blood and lymph, and functions by means of two interacting modes of circulation, the cardiovascular system and the lymphatic system; both the fluid components and the vessels through which they flow reach their greatest elaboration and specialization in the mammalian systems and, particularly, in the human body. conducting system of the heart. This system has three main functions: Protection of the body by white blood cells, antibodies, and complement proteins that circulate in the blood and defend the body against foreign microbes and toxins. bookmarked pages associated with this title. To help maintain fluid balance within the body Broken Capillaries: Causes and Treatments. This system causes heart muscle depolarization in only one direction- from the atria to the ventricles; it enforces a contraction rate of approximately 75 beats per minute on the heart, thus the heart beats as a coordinated unit.
