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.

Both Lev Vygotsky and Jean Piaget believed that<em> children were active participants in their learning.</em> (Option D)
<h3>What did
Lev Vygotsky and
Jean Piaget research?</h3>
Piaget suggested that children go through cognitive development stages via maturation, discovery techniques, and certain social transmissions via absorption and adaptation (Woolfolk, A., 2004). Vygotsky's approach emphasized the significance of culture and language in cognitive development.
Both Jean Piaget and Lev Vygotsky, psychologists, developed unique perspectives to the cognitive-development dilemma in the discipline of psychology. While both Piaget and Vygotsky believed that children actively create knowledge through speech acquisition.
Vygotsky proposed that cognitive growth happens in conjunction with others and cannot proceed without language and interaction. Piaget thought that children learn autonomously and develop their own unique worldview.
Vygotsky agreed with Piaget that cognitive capacities grow in stages and agreed essentially with the description of the phases, but he saw cognitive development as a social process in which youngsters learn from experienced adults. According to Vygotsky, language serves two purposes.
