unit 1 EHS pos & body cavity pt 2

Anatomical Position

Body erect, arms at sides, palms forward.

Bilateral Symmetry

Body divided into symmetric left and right sides.

Ipsilateral

Refers to the same side of the body.

Contralateral

Refers to the opposite side of the body.

name the 2 major body cavities

dorsal and ventral

list the primary anatomical areas or components of ventral cavity

Contains thoracic and pleural, mediastinum, abdominopelvic cavities, abdominal and pelvic

list primary anatomical areas or components of dorsal cavity

cranial, spinal

describe axial subdivision in skeletal body regions

head, neck, torso (ribs, spinal column)

Describe the appendicular skeleton body region

upper and lower extremities

Right Hypochondrial Region

Upper right region of the abdominopelvic cavity.

Name the 9 abdominal regions of the abdominopelvic cavity

right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, left iliac

name top row of abdominopelvic region

right hypochondriac, epigastric, left hypochondriac

name middle row of abdominopelvic regions

right lumbar, umbilical, left lumbar

name bottom row of abdominopelvic regions

right iliac, hypogastric, left iliac

name 4 abdominopelvic quadrants

right upper quadrant, left upper quadrant, right lower quadrant, left lower quadrant

compare and contrast anatomy and physiology

Anatomy is the study of the structure of a living organism and its component parts. Physiology is the study of the normal functioning of a living organism and its component parts

name and describe the 3 ways anatomy and physiology can be subdivided. provide examples

level of organization: cellular anatomy/ physiology, type of organism: plants, specific body system: cardiovascular

describe how characteristics of life, growth+ reproduction work together to allow humans to live

without reproduction creating new cells, then growth can't grow organism cells

describe how responsiveness and conductivity allow humans to live

conductivity transmits impulses and responsiveness responds to the impulses to sense change in its environment

how does respiration and circulation allow humans to survive

respiration exchanges CO2 and oxygen and circulation moves substances from 1 part of body to another

how does digestion, absorption, secretion, and excretion allow humans to live

digestion breaks down food, absorption absorbs it, secretion aids digestion, excretion removes any waste

list levels of organization from smallest to largest

chemical, organelle, cellular, tissue, organ, system, Organism

definition of the chemical level of organization

over 100 atoms combine to form macromolecules

definition organelle level of organization

collections of molecules that perform a specific function

definition of cellular level of organization

smallest unit that possess characteristics of life

definition of tissue level of organization

organization of similar cells that perform a specific function

definition of organ level of organization

organization of several tissues arranged to perform a specific function

definition of system level of organization

organs arranged to perform complex functions in body

Organism level of organization

all the organ systems of the body work together to maintain life and health

example of chemical level of organization

amino acids
