Explanation:
During systole of ventricles, the heart undergoes a series of events that ultimately result in the contraction of the ventricles and the ejection of blood from the heart. Here, we will discuss the events that occur during systole and how blood leaves the ventricles.
Events during systole:
1. The ventricles contract, causing the pressure inside them to increase.
2. The pressure inside the ventricles exceeds the pressure in their respective arteries (the aorta and pulmonary artery), causing the semilunar valves to open.
3. Blood is ejected from the ventricles into their respective arteries.
4. The atria are relaxed during systole, allowing them to fill with blood.
How blood leaves the ventricles:
During systole, blood leaves the ventricles and enters their respective arteries. The left ventricle pumps oxygenated blood into the aorta, which delivers it to the rest of the body. Meanwhile, the right ventricle pumps deoxygenated blood into the pulmonary artery, which carries it to the lungs for oxygenation.
Therefore, we can conclude that during systole of ventricles, blood leaves the ventricles and enters their respective arteries.
