Midsagital plane (equal)
Coronal plane / frontal
Divides the body into front & back parts
Mid coronal (equal)
Transverse plane
Divides body into inferior and superior parts
Dorsal cavity
Cranial cavity (houses brain)
Spinal cavity (houses spinal cord)
Ventral cavity

Abdominal cavity ( GI organs )
Pelvic cavity ( urinary and reproductive organs )
Diaphragm separates between __ &___ cavity
Thoracic & abdominal cavity
4 quadrants of abdomin
RUQ LUQ
RLQ LLQ
9 abdominal regions
Right hypochondriac Epigastric Left hypochondriac
Right lumbar Umbilical Left lumbar
Right iliac crest Hypogastric Left iliac
Serious membranes keep organs ____ & secret _____
Seperated
Serious fluid (decrease friction with organs)
Visceral membrane
Serous membrane that covers organs
Serous cavity
Space in between the visceral & parietal membrane that contains the serous fluid
Parietal membrane
The serous membrane lining the body cavity
Pleura =
Lungs
Visceral pleura = membrand on lungs
Parietal pleura = membrane on thoracic cavity
Pericardial =
Heart
Visceral pericardium = membrane around heart
Parietal pericardium = membrane around thoracic cavity
Mediastinum
Space between the lungs that has the heart great vessels trachea &
Esophagus
Peritoneum =
Abdominal cavity
Visceral peritoneum = membrane around abdomin / pelvis
Parietal peritoneum = membrane around abdominal pelvic cavity
Extracellular fluid
Body fluids outside the cell
Intracellular fluid
The body fluid within the cell
Intracellular fluid and extracellular fluid make up ___ of body weight
60%
Negative feedback
This effect will oppose or eliminate the stimuli
Positive feedback
Stimulus produced response that exaggerate or enhances what is happening
Ex contractions
Negative and positive feedback maintain :
Homeostasis
Metabolism
All life sustaining reactions that go in within the body
Catabolism

Ex digesting food
