chapter 1: an intro to the human body Flashcards
to cut up; the scientific study of the body’s structures
anatomy
anatomy of larger objects
ex) brain, heart, liver, etc.
gross anatomy
anatomy of smaller objects
ex) cells, tissues, etc.
microscopic anatomy
the scientific study of the chemistry and physics of the structures of the body and the ways they work together to support the functions of life
physiology
- consider source
- evaluate content
- question the methods by which data and information were gathered
- understand your own biases and values
critical thinking
atoms, molecules, macromolecules
chemical level
cells, organelles
cellular level
group of similar cells that work together to perform a specific function
tissue level
two or more different tissues combine to form an organ
organ level
two or more organs work closely together to perform the functions of a body system
organ system
many organ systems work harmoniously together to perform the functions of an independent organism
organismal level
needs of human life
- food/nutrients
- water
- oxygen
- maintain temperature
- maintain pressure
5 characteristics of human life
- grow and reproduce
- use energy and raw materials
- movement
- composed of cells
- maintain homeostasis
steady state of body systems that living organisms maintain
homeostasis
biological response that slows or stops a reaction to maintain balance in the body
ex. body temp regulation
negative feedback loop
mechanisms that intensify a change in the body physiology condition in response to a stimulus
ex. childbirth
positive feedback loop
cavity of the head (spinal cord)
cranial cavity
cavity of the chest (heart, lungs, etc.)
thoracic cavity
cavity below the diaphragm
abdominal cavity
cavity in the pelvis region
pelvic cavity
cavity with abdomen and pelvis
abdominopelvic cavity
cavity with torso and pelvis
ventral cavity
