The cardiac cycle consists of two phases; a period where the heart muscle is relaxed, called <u>diastole</u>, and a period of contraction, called <u>systole</u>.
These are then divided into four stages. These are;
1.<u>Ventricular Filling Period (VPF)</u>
2. <u>Isovolumetric Contraction Period (ICP)</u>
3. <u>Ventricular Ejection Period (VEP)</u>
4.<u> Isovolumetric Relaxation Period (IRP)</u>
At rest, cardiac diastole lasts for approximately 0.5 seconds, and cardiac systole lasts approximately 0.3 seconds to complete. However, during exercise, when the heart rate is increased the time period of <u>diastole</u> , especially, is reduced.

<span>The correct answer is A. In the afternoon. It's not right after a meal and it's not like you just woke up and are not fully awake. It's also good because it's not the hottest part of the day so you won't overheat and suffer a heatstroke. Afternoon is therefore the perfect period for working out.</span>
Answer:
Sarah's calculation isn't correct.
Explanation:
Both milliliters (ml) and ounces (oz) are units used to measure the volume of fluid. One ounce is about 29.6 milliliters. If we multiply this by 16, we'll get about 473ml, which doesn't fit Sarah's original measurements. 473ml is obviously way less than 630ml. Her calculation would be correct if she wrote down 21.3oz (630ml ÷ 29.6 = 21.3oz).
