Human Body / Orientation Flashcards
Physiology
Concerns a function of the body how the body parts work and carry out their life sustaining activities
Gross anatomy
The study of large body structures visible to the naked eye such as the heart longs and kidney
Greek means of anatomy
To cut apart
Regional anatomy
Where all the structures in a particular region of the body or studied
Systemic anatomy
Where body structures or study by system for example the cardiovascular system
Gross anatomy’s subdivision
Surface anatomy
which is the study of internal structures as they relate to the overlying skin surface
Microscopic anatomy
Deals with structures too small to be seen with the naked eye
Subdivisions of microscopic anatomy
Cytology which is it considers the cells of the body and
histology which is the study of tissues
Developmental anatomy
Changes of the body throughout the lifespan
Subdivision of developmental anatomy
Embryology
Changes that occur before birth
Pathological anatomy
Changes caused by disease
Radiographic anatomy
Structures visualize by x-ray
Levels of structural organization
Chemical level
cellular level
tissue level
organ level
organ system level
and organism level
Anatomy
Studies the structure of body parts and the relations to another
How are organelles made
Molecules associate specific ways to form organelles
When atoms combine went to the form
Molecules
The simplest living creatures are
Single cells
Tissues
Similar cells that have a common function
Four basic tissue types
Epithelium
Connective
Muscle
Nervous
Epithelium covers?
Body surface and lines its cavities
Muscle provides?
Movement
Connective tissue supports?
Supports and protects body organs
Nervous tissue provides?
Means of rapid internal communication by transmitting electrical impulses
Contractility
Muscle cells ability to move by shortening
Responsiveness or excitability
The ability to sense changes (stimuli) in the environment and then respond to them
Digestion
Breaking down food to simple molecules that can be absorbed into the blood
Metabolism
All chemical reactions that occur within the body’s cells
Breaking down substances into simple building blocks (Catabolism)
Anabolism- synthesizing complex cellular structures from simpler substances but requires energy
Oxygen and nutrients create ATP via cellular respiration
What covers the body , protects deeper tissues from injury , synthesizes vitamin D , houses pain and pressure receptors and sweat glands and also oil glands
Integumentary system
What protects and supports body organs and provides a framework for muscles, forms blood cells and stores minerals?
Skeletal system
What picks up fluid leaked from blood vessels and returns it to the blood. disposes to debris in the lymphatics stream and houses white blood cells?
Lymphatic system
What eliminates nitrogenous waste regulates water electrolyte and acid-base balance of the blood?
Urinary system
What process removes waste
Excretion
Carbohydrates are essential for what?
Major energy fuel for body cells
What is essential for building cell structures?
Proteins and fats
What provides reserve energy ?
Fats
What happens when the body temperature drops below 98.6
Metabolic reactions become slower and slower until they stop
If body temperature is too high what happens?
Chemical reactions occur in a frantic pace,
the body proteins lose their characteristic shape and and stop functioning
What are the five survival needs?
Nutrients Water Oxygen Normal body temperature Atmospheric pressure
