Answer:
Sinoatrial Node
Explanation:
The sinoatrial node is like the natural pacemaker of the heart because it controls the heart beat or in other words, the cardiac rhythm. The sinoatrial node is found on the right atrium and it sends signals to both atria and then they contract. The signal is then carried to the atrioventricular node which spreads the signal to the ventricles and then the ventricles contract. The contractionof the ventricle is the pumping action of the heart.
Answer:
True
Explanation:
Pulmonary circulation transports blood through the alveoli for gas exchange. In this circulation the blood that comes from the veins initially has low oxygenation, and then leaves the right ventricle of the heart through the pulmonary artery, enters the lungs and returns to the heart with arterial and oxygenated blood
The bronchial circulation is well oxygenated and provides oxygen to the lungs. The structures to which this oxygen contributes in lungs are those that do not participate in a gas exchange.
