The heart holds many mysteries. Connect the dots to uncover one of them: how much blood flows through its chambers.
In the lungs, what waste product does deoxygenated blood exchange for more oxygen?
What happens to the oxygen in blood when it leaves the heart?
Aligned with Next Generation Science Standards (NGSS):
K-LS1-1. Use observations to describe patterns of what plants and animals (including humans) need to survive.
1-LS1-1. Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.
4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction.
MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
