human body anaphy lab Flashcards
The study of the structure and shape of the body and its parts and their relationship to one another
Anatomy
what are the two majors of anatomy?
Gross and microscopic anatomy
what is gross anatomy?
deals with the structures of the body that are visible to the naked eye
what is microscopic anatomy?
is a branch of anatomy that relies the use of microscope to examin the smallest structures of the body
What are the three smallest structures of the body to examine using a microscope?
tissue , cells ,molecules
what is Physiology?
the study of how the body and its parts work or function.
the tiny building blocks of matter
atoms
group of two or more atoms
molecules
group of two or more atoms
cells
consists of groups of similar cells that have a common function
tissues
what are the 4 types of tissues?
C-onnective tissue
E-pithelial tissue
M-uscular tissue
n-ervous tissue
a structure composed of two or more tissue types that performs a specific function for the
body
organ
a group of organs that work together to accomplish a common purpose
Organ system
Atoms combine to
form molecules
Chemical level
Tissues consist of similar types of cells
Tissue level
Organs are made up of different types of tissues
Organ level
Organ systems consist of different organs that work together closely
Organ system level
Human organisms are made up of many organ systems
Organismal level
-External covering
– Produces vitamin D
– Excretes salts in perspiration; regulate body temperature
- Integumentary system
- Supports the body and provides a
framework that the skeletal muscles use to
cause movement
– Bones
Skeletal system
Allows movement of the body
– Function: contractibility
– Specialized cells called muscle fibers
- Muscular system
Fast acting control system
– Respond to internal and external stimuli
– Sensory receptors
* Detect changes in temperature, pressure, or light
* Sends messages to the CNS
Nervous system
– Controls body activities
– Produce chemical molecules called HORMONES
– Release to distant target organs
- Not connected to each other
- Endocrine system
Heart and blood vessles
– Delivers oxygen, nutrients, hormones, and other substances
to, and picks up wastes such as carbon dioxide from cells
near sites of exchange
– Heart – propels blood out of its chambers into blood vessles
- Cardiovascular system
