1). Anatomy and Physiology is a branch of science, in which anatomy deals with the “morphological structures” various organs of the body and physiology deals with their “functioning.”
For example, right atrium, myocardium, left ventricle, endocardium, and superior vena cava are the example terms of anatomy.
Thus, aorta opens, the valve between the left atrium and left ventricle closes, the pressure in the left atrium, electrocardiogram and, heartbeat are the example terms of physiology.
2). The human body illustrates the “levels of organization.” Group of atoms (and subatomic particles) form a molecule, group of molecules form a macromolecule, group of macromolecules forms an organelle, group of organelles form a cell, group of cells form a tissue, group of tissues form an organ, group of organs form an organ system, organ systems group to form an organism.
