Separate pages describe the types and structures of arteries, characteristics of blood flow, and information on lipoproteins ..
The modest size and weight of the heart give few hints of its incredible strength. Pulmonary circulation includes the vast network of arteries, veins, and lymphatics that function to exchange blood and other tissue fluids between the heart, the lungs, and back. This article provides an overview of this essential body system. An average human has around 5 liters (8 pints) of blood, which is … The circulatory system is responsible for the transport of water and dissolved materials throughout the body, including oxygen, carbon dioxide, nutrients, and waste. The blood carries a number of other substances required by the body to function. Weight. The cardiovascular system can be compared to a muscular pump equipped with one-way valves and a system of large and small plumbing tubes within which the blood travels. Human Anatomy & Physiology: Circulatory System, Ziser Lecture Notes, 2013.11 3 The Circulatory System (Cardiovascular System) major connection between external and internal environment: everything going in or out of body must go through the circulatory system to get to where its going more than 60,000 miles of blood vessels with a pump The cardiovascular system keeps life pumping through the body.

The circulatory system includes the heart, arteries, veins. The Circulatory System—Part I Anatomy and Physiology. They are designed to perform certain specific functions that are unique to the pulmonary circulation, like exchanging gases in the lungs and acting as a reservoir for the storage of blood amongst others.
