Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.

Scientists sometimes make discoveries that lead to a need for new laws. This illustrates the general situation of science not just biology in pursuing scientific inquiry. Some of the classical experiments like the Mendel's crosses of the pea plant to understand the inheritance pattern of various observed traits required Mendel to come up with a hypothesis turned theory of independent assortment of genes. With substantial experimental trails on pea plants this theory turned into a law due to the increased number of supporting evidence.
This is false...Hope this helps!! Tell me if im wrong though...
Herbivores are consumers :)
