Formed by the left part of the heart and the body systems. The lungs send blood rich in oxygen to the left atrium. The left ventricule pumps it to the different body systems through the aorta. Recieves the electric impulse from the sinoatrial node, moderates it and controls it Recieves the oxygenated blood coming from the lungs through the pulmonary veins. It later pumps the blood to the left ventricule. Pressure inside the blood vessels while the heart is relaxed. The average is of 80 mmHg Recieves blood from the left atrium and it pumps it to the rest of the bodyt through the aorta. It is also known as pacemaker. It sends electric impulses that control the heart rithym, causing the contraction of the cardic muscles. It is formed by the right part of the heart and the lungs, The venas cavas take blood low in oxygen to the right atrium. The right ventricule pumps it to the lungs trough the pulmonary arteries. The lungs send back to the heart blood rich in oxygen through the pulmonary veins. Pressure inside the blood vessels during the heart contractions; the average is 120 mmHg. It recieves blood from the right atrium and it pumps it to the lungs through the pulmonary arteries.
