Summary Introduction

Concept introduction: To sustain life, the blood must circulate all along the body. It transports oxygen and all other essential nutrients to different parts of the body. There are two major circulation pathways namely systemic and pulmonary circulation. In systemic pathway, oxygenated blood from lungs entering into the left atria is carried to the left ventricle. From the left ventricle, the oxygenated blood gets pumped into the aorta. Many arteries arising from the aortal vessel transport this oxygenated blood into different parts of the body. In pulmonary pathway, it starts from the collection of deoxygenated blood from different body parts by veins and pours it into the right atrium to filling oxygenated blood to the left atria.
