This includes the generalized and more specialized functions of transport of materials, capillary exchange, maintaining health by transporting white blood cells and various immunoglobulins (antibodies), hemostasis, regulation of body temperature, and helping to maintain acid-base balance. Virtually every cell, tissue, organ, and system in the body is impacted by the circulatory system. Create a flow chart showing the major systemic veins through which blood travels from the feet to the right atrium of the heart.Create a flow chart showing the major systemic arteries through which blood travels from the aorta and its major branches, to the most significant arteries feeding into the right and left upper and lower limbs.Identify the vessels through which blood travels within the pulmonary circuit, beginning from the right ventricle of the heart and ending at the left atrium. By the end of this section, you will be able to:
