The human circulatory system comprises independent systems such as the heart (cardiovascular), lungs (pulmonary), arteries, veins, and coronary and portal vessels (systemic) that work together. The circulatory system is responsible for the flow of blood, nutrients, oxygen, and other gases, as well as other hormones to and fro from the cells.
The students were segregated into groups titled, Artery, Vein, and Capillaries. Each member of the groups was then regrouped into Pulmonary and Systemic category groups using One stray method of flipped classroom teaching technique. The sharing of information was carried out in the form of a quick presentation with the help of a model of the heart. The learners were overwhelmed with understanding the role of valves that ensure unidirectional blood flow and prevent backflow, essential for maintaining the heart’s pumping action.
Overall, it was an effective classroom activity wherein the learners enjoyed the session and seemed enthusiastic in exploring the structure and functions of the cardiac system.
