ANATOMY AND PHYSIOLOGY Flashcards
Study of the
structure and
shape of the
body and its
parts
Human Anatomy
–Large
structures
–Easily
observable
Gross anatomy
–Structures are
too small to be
seen with the
naked eye
Microscopic Anatomy
–Structures are
too small to be
seen with the
naked eye
Microscopic Anatomy
– Cells and
tissues can be
viewed only
with a
microscope
Microscopic anatomy
– Cells and
tissues can be
viewed only
with a
microscope
Microscopic anatomy
The science of the function of the most
wondrous of all structure
- the human body
Human Physiology
What are the 10 characteristics in life
1.movement
2. responsiveness
3. Growth
4. Reproduction
5. Respiration
6.digestion
7. Absorption
8. Circulation
9. Assimilation
10. Excretion
Removal of wastes
Excretion
Changing absorbed substances into
chemically different substances
Assimilation
Movement of substances throughout
the body
Circulation
Passage of digested products (food)
through membranes and into body
fluids
Absorption
Chemically changing (breaking down)
food
Digestion
Obtaining oxygen (O2)
Respiration
DNA passed from parents to offspring
Reproduction
Increase in body size
Growth
Ability to sense changes and react
Responsiveness
Self initiated change in position, motion
of internal parts
Movement
The body is a large structural unit
made up of many millions of smaller
parts of four kinds and what arre those 4 kinds?
A. Cells
B. Tissue
C. Organ
D. System
Smallest units that can maintain life
and reproduce themselves
Average-sized adult body consists of
100, 000, 000, 000, 000
Cells
Organizations of many similar cells with non-living intercellular substances between them
Tissues
An organization of several different kinds of tissues so Arranged that together they can perform a special function
Organ
An organization of varying numbers and kinds of organs So arranged that together they can perform complex functions for the body
System
How many levels of structural organization and what are those?
6 level and these are:
1. atoms
2. Cells
3. Tissues
4. Organ
5. Organ systems
6. Organisms
How many major systems in the human body and what are those
9 and these are:
1. Skeletal system
2. Muscular
3. Respiratory
4.circulatory
5. Digestive
6. Nervous
7. Urinary
8. Endocrine
9. Reproductive
house the
numerous internal organs (viscera) of
the body
Ventral and dorsal cavities
Right pleural cavity contains right lung;
left pleural cavity contains left lung
❖Pleural cavities
Thoracic (Chest) Cavity
Ventral Cavity
Midportion of the thoracic cavity
❖Mediastinum
Completely separated from pleural
cavities by fibrous tissue wall
❖Mediastinum
❖Mediastinum contains?
⮚heart
⮚trachea and bronchi
⮚esophagus and thymus
⮚various blood vessels, lymphatics, and nerves
Abdominal portion:
❖Abdominopelvic Cavity
