1. Pulmonary refers to the lungs
2. Elastic recoil- think about high pressure
3. This time, think about low pressure
Essentially, a double circulatory system refers to a system where blood passes the heart twice in order to complete a circuit. This means that oxygenated and deoxygenated blood are divided into 2 chambers and cannot mix, hence making it more effecient than a single circulatory system found in fish.
Remember that you're looking at the heart as you're facing another person so right and left are flipped.
If we start from the left artium, blood moves to the left ventricle then through the aorta to the rest of the body. Oxygen is used and deoxygenated blood returns to the heart via the vena cava into the right atrium, right ventricle then leaves via the pulmonary trunk to the lungs. Blood is oxygenated and returns to the heart via the pulmonary vein back to the left atrium.
