In this agribusiness lesson, students learned about the blood of rabbits and how it interacts with other systems in their bodies. Blood is composed of several components, including red blood cells, white blood cells, plasma, and platelets, and plays a crucial role in the circulatory system. The heart pumps oxygenated blood through arteries and capillaries, facilitating oxygen exchange within the body. The lesson also emphasized the importance of vital organs, such as the heart, lungs, and brain, and their interconnectedness within the circulatory and respiratory systems.
