Anatomy Basics Flashcards
The study of the structure of the body with the unaided eye
Gross anatomy
The study of cells and tissues (microscopic)
Histology
Embryology
Study of development ( gametes, fertilization, embryo, fetus)
Structural organization of the body
Chemical, cellular, tissue, organ, organismal level
Chemical level
Atoms and molecules
Cellular level
Cells and their components
Tissue level
An assemble of similar cells that carry out a specific function
A collection of tissues joined in a structural unit to serve a common function
Organ level
A contiguous living system, capable of responding to stimuli, reproduction, growth and development
Organismal level
Characteristics of living things
OMG/DRARR
Complex, yet organized, components
Organization
Break down and utilize nutrients and generate waste
Metabolism
Maturation of an organism
Growth and development
Organisms must be able to perceive and respond to changes in their environment
Responsiveness
Organisms must be able to change functionally and structurally
Adaptation
Organisms must be able to keep a stable internal environment
Regulation
Organisms produce sex cells to give rise to new organisms
Reproduction
A group of organs that work together to perform one or more functions
Organ system
Major organ systems…
Integumentary, skeletal, muscular, nervous, cardiovascular, lymphatic, respiratory, digestive, urinary, reproductive, endocrine
Functions of the integumentary system…
Protection, regulates body temperature, contains sensory receptors, synthesizes vitamin D, prevents water loss
Functions of the skeletal system
Support and protection, site of hemopoiesis and muscle attachment, stores calcium and phosphorus
Functions of the muscular system
Produces body movement and generates heat
Functions of the nervous system
Response to sensory stimuli, activates muscles and glands, controls other systems, responsible for consciousness, intelligence, and memory
Functions of cardiovascular system…
Moves blood, distributes hormones/nutrients/ and gases to tissues, picks up waste products from tissues
Functions of lymphatic system
Transports and filters lymph, initiates immune response
Functions of respiratory system…
Air into body, gas exchange between lungs and bloodstream, allows for vocalization
