Chapter 1 Flashcards
anatomy
the study of structure and form
macroscopic/gross anatomy
large body structures visible to the eye. exs. systemic, regional, surface, comparative, embryology
microscopic anatomy
study of structures that requires magnification to be seen. exs. cytology, histology
physiology
the study of function
-how organisms perform vital functions and how function is altered.
-focuses mainly on molecular and cellular levels
characteristics of living organisms
1. growth and development
increase in size and specialization
characteristics of living organisms
2.metabolism
sum of chemical reactions
characteristics of living organisms
3. responsiveness
sense and react to stimuli
characteristics of living organisms
4. regulation
adjust internal function as the environment changes
characteristics of living organisms
5. reproduction
produce new cells for growth, maintenance, repair, production of offspring
characteristics of living organisms
6. organization
have complex structure and order

levels of organization
1.
chemical level
atoms
smallest unit of matter exhibiting characteristics of an element
molecules
combinations of atoms ex glucose
organelles
specialized microscopic subunits in cells. ex. ribosomes make proteins
levels of organization
2.
cellular level
-smallest unit of life
- structural building blocks
-produced from pre-existing cells
levels of organization
3.
tissue level
-groups of similar cells perform a common function
tissue level subtypes (4)
- epithelial
- connective
- muscular
- nervous
tissue level subtypes (4)
1. epithelial
cover and line surfaces
tissue level subtypes (4)
2. connective
bind, protect, support
tissue level subtypes (4)
3.muscular
produce movement
tissue level subtypes (4)
4. nervous
communication
levels of organization
4.
organ level
-two or more tissues working together to perform a specific, complex function
levels of organization
5.
organ system level
-related organs that work together to coordinate activities and function ex. respiratory system
levels of organization
6.
organismal level (the person)
respiratory system
gas exchange between air in the lungs and blood
nervous system
control muscles and some glands, respond to stimuli, consciousness, memory, intelligence
muscular system
produce body movements, generate heat
reproductive system
produce sex cells and hormones; in females, growth and development of embryo/fetus/newborn
lymphatic system
transport and filter lymph, participate in immune response
urinary system
filter waste from blood, concentrate and expel waste as urine
digestive system
mechanically and chemically break down food, absorb nutrients, expel waste
endocrine system
secrete hormones to regulate growth, metabolism, digestion, reproduction, and maintain homeostasis
integumentary system
protect, regulate body temperature, vitamin D synthesis, prevent water loss
cardiovascular system
move blood through body to distribute hormones/nutrients, and pick up waste
skeletal system
support, protect, hemopoiesis, calcium, and phosphorous storage, muscle attachment
anatomical postion
-standing upright, feet parallel flat on floor
-upper limbs at sides palms forward
-head level, eyes forward
anterior/ventral
toward the front

away from midline
ipsilateral
same side
contralateral
opposite side
proximal
closer to attachment
distal
farther from attachment
superficial
near body surface
deep
away from body surface
sagittal
vertical division between left and right
midsagittal
split down midline resulting in equal left and right halves

serous membrane
thin layer of epithelial tissue, looks like 2 layers, is actually one folded back on itself
serous membrane, outer layer
parietal layer
serous membrane, inner layer
visceral layer
serous fluid
fills the cavity between the two layers
function of serous fluid
watery, slippery
lubricates organs to prevent friction
regional anatomy
examines all the structures in a particular region of the body as a complete unit
systemic anatomy
studies the anatomy of each functional body system
surface anatomy
focuses on both superficial anatomic markings and the internal body structures that relate to the skin covering them. ex. you use superficial markings to know where to do CPR
physiology focuses on the _______ or _____ level to gain an understanding of how organ systems work
molecular or cellular
