ATI TEAS Study Guide (Latest Update )ATI Notes – General Anatomy & Physiology of a Human - Lowest hierarchy is at the organelles within a cell - Cells with the same functions collected into larger groups - tissues - Tissues are collected into organs which carry out a single task - Organs work together in organ systems that perform large-scale functions Cell Parts - Organelles - cell parts that function within a cell o Coordinate with other organelles to perform a cell’s basic functions - Ribosomes - carry out protein synthesis - Golgi Apparatus - modifies & packages proteins secreted from a cell - Mitochondria - convert energy present in chemical bonds of food accessible to the cell - Nucleus - stores & processes instructions contained in the DNA that tell the cell what its functions are Cells - Smallest living unit of life - In humans, some cells function autonomously; ex. Phagocytic white blood cells - Cells highly specialized to perform a specific function Organs - Structures composed of several types of tissues & perform one or more functions Organ Systems - Functional units composed of several organs - Functions include: digestion of food, circulation of nutrients, removal of wastes, & reproduction Vocab: - Anatomical Position: standard positioning of the body as standing; feet together; arms to the side; with head, eyes, and palms of hands forward - Cells: the basic structural unit of an organism from which living things are created - Cellular functions: Processes that include growth, metabolism, replication, protein synthesis, and movement - Directional Terminology: Words used to explain relationships of locations of anatomical elements - Organelle: a specialized part of a cell that has a specific function - Organ: a self-contained part of an organism that performs a specific function
