Introduction to Anatomy, Cells and Tissues Flashcards
(40 cards)
Traces structural changes that occur throughout a human lifespan.
Developmental Anatomy
Deals with the cells’ structural features
Cytology
Level of Anatomy where you can percieve structures without the aid of a microscope. Either systemic or regional perspective can be used to utilized.
Gross Anatomy
The study of how the body and its parts work or functon and carry out their life-sustaining activities.
Physiology
Medical science dealing with all aspects of diseases.
Pathology
Level of organization of the human body that involves interactions between atoms, which are tiny building blocks of matter. Atoms combine to form molecules, such as water, sugar, fats, and proteins.
Chemical Level
Level of organization of the human body that involves molecules combine to form organelles which are the small structures that make up cells - the smalled unit of all living things
Cell Level
Level of organization of the human body that involves group of cells and materials that are similar together, merge together to form tissues - epithelial, connective, muscle, and nervous tissues.
Tissues Level
Level of organization of the human body that involves a structure composed of two or more tissue types that performs a specific function for the body. In this level,extremely complex functions become possible.
Organs Level
Level of organization of the human body that involves a group of organs that work together to accomplish a common purpose or to perform a common function or set of functions and are therefore viewed as a unit
Organ Systems Level
Level of organization of the human body that involves everything tied up together. Complex organ systems are all mutually dependent on each other, trillon of cells and bacterium live inside of a stable ecosystem that is unbeknownst to us.
Organism Level
Characteristic and a requirement of life that includes all the activities promoted by the muscular system, such as propelling ourselves from one place to another, with the skeletal system provides the bones that the muscles pull on as they work.
Movement
Characteristic and a requirement of life that includes the ability to sense changes (stimuli) in the environment and then to react to them.
Responsiveness
Characteristic and a requirement of life that includes the process of breaking down ingested food into simple molecules that can then be absorbed into the blood.
Digestion
Characteristic and a requirement of life that include all chemical reactions that occur within the body and all of its cells. It includes breaking down complex substances into simpler building blocks (as in digestion), making larger structures from smaller ones, and using nutrients and oxygen to produce molecules of adenosine triphosphate (ATP), the energy-rich molecules that power cellular activities.
Metabolism
Characteristic and a requirement of life that includes the production of offspring, which can occur on the cellular or organismal level. Without this ability, species become extinct.
Reproduction
Characteristic and a requirement of life that includes an increase in cell size or an increase in body size that is usually accomplished by an increase in the number of cells.
Growth
Change in cell structure and function from generalized to specialized.
Differentiation
Change in the shape of tissues, organs, and the entire organism. For example, following fertilization, generalized cells specialize to become specific cell types, such as skin, bone, muscle, or nerve cells.
Morphogenesis
A set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other reactions.
Catabolism
The Smallest Unit of life
Cell
Includes interstitial fluids, blood plasma, and the cerebrospinal fluid.
Extracellular Fluid
Component of a cell where it is a Phospholipid Bilayer with protein moleciles in as a fluid mosaic.
Plasma Membrane
Function of that component of a cell where it determines which substances enters or exit the cell.
Selective Permeability
