Figure 18.2.1 : Cardiovascular Circulation in Pulmonary and Systemic Circuits
The pulmonary circuit moves blood from the right side of the heart to the lungs and back to the heart. The systemic circuit moves blood from the left side of the heart to the head and body and returns it to the right side of the heart to repeat the cycle. Blood flows in one direction to and from capillary beds, each with a network of interconnected capillaries, that are positioned between the arterial and venous sides of circulation throughout the body to allow for gas and nutrient exchange. In the pulmonary circuit, deoxygenated blood flows on the arterial side of the circuit while oxygenated blood flows on the venous side. In the systemic circuit, oxygenated blood flows on the arterial side of the circuit while deoxygenated blood flows on the venous side. In the figure, the arrows indicate the direction of blood flow and the colors show the relative levels of oxygen concentration.
