From cranium to fingertip, marvel at the rich. So understanding Physiology requires an understanding of Anatomy, and vice versa. Assemble an Accurate Cross-cut of the Entire Human Body From Pre-order for Kids Anatomy Jigsaw Floor Puzzle. The way structures work depend on the way they are organized. A muscle contracts and brings bones together (function) due to the arrangement of muscles and bones, and the arrangement of organelles inside of muscle cells (form) determines how much and for how long a muscle can contract (function).īody structure functions depend on their form. A hand is able to grab things (function) because the length, shape, and mobility of the fingers (form) determine what things a hand can grab (function). Physiology focuses on function, or how structures at different levels work.Īnatomy and physiology are intimately related. Human Physiology (physio = “nature” -logy = “study”) studies the “nature” of the human body, nature in the sense of how structures at different levels work. Gross anatomy studies macroscopic structures (for example, the body, organs, and organ systems), and histology studies microscopic structures (for example, tissues, cells, and organelles). Anatomy focuses on the description of form, or how body structures at different levels look. Human Anatomy (ana- = “up”, tome = “to cut”) is often defined as the study of structures in the human body. Define the terms anatomy and physiology, and give specific examples to show the interrelationship between anatomy and physiology.
