attached to the heart‚ and what does it do? The largest vessel that is attached to the heart is the aorta. This carries nutrient filled blood to the rest of the body. 3. What is pulmonary circulation? Pulmonary circulation is the circulation of blood from the heart to the lungs through the pulmonary artery and pulmonary veins. The heart pumps deoxygenated blood from the heart to the lungs and then the blood is sent back being oxygenated‚ where it is then pumped to the rest of the body. 4

had no idea about real medicine before they started to translate Arabic books into their languages in mid-twelfth century. 6. Who was the real discoverer of the pulmonary circulation? The scientist physician Ala’uddin ibn Al.Hassan Al.Dimashqi ibn Al.Nafees (born in the Levent 1210 AD) was the first to describe the pulmonary circulation. That was mentioned in his book "Commentary on Anatomy in Avicenna’s Canon". 7. How did the world know the real discoverer?

lungs for new oxygen; the left side of the heart receives blood rich in oxygen from the lungs and pumps it through the arteries to the various parts of the body. Circulation begins early in fetal life. It is estimated that a given portion of the blood completes its course of circulation in approximately 30 seconds. Pulmonary circulation is where the blood from the entire body is transported to the right auricle through two large veins. The superior vena cava and the inferior vena cava. When the

Biology Tuesday‚ January 17‚ 2012 Cardiovascular System The heart weighs 300 grams and is shaped like a grapefruit and has two atria‚ two ventricles‚ and four valves receive blood from both venae cavae and the four pulmonary veins‚ and throw it into the aorta and pulmonary trunk. The heart pumps blood to 9 liters per day‚ making from 60 to 160 beats per minute. The heart is covered with a dense fibrous membrane - the pericardium‚ forming serous cavity filled with liquid‚ which prevents

pathways: the pulmonary pathway and the systemic pathway. The blood flowing in the pulmonary pathway is deoxygenated‚ and it delivers this blood to the lungs to be oxygenated again. The blood flowing in the systemic pathway leaves the lungs full of oxygen and flows through the heart to be delivered to the body tissues. Instructions: Complete the following table to demonstrate the correct order for the pulmonary and systemic circulation as you trace a drop of blood through the body. Pulmonary Circulation

Pulmonary circulation: Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where the blood picks up oxygen and returns to the left side of the heart. The pumping chambers of the heart that support the pulmonary circulation loop are
