x A&P - Ch 1, organization of the human body Flashcards
Levels of Organization
CHEMICALS:
CELLS: chemicals form living cells, mitochondria, neuron, cuboidal epithelium
TISSUE: specialized group of cells form
ORGANS: tissue function together to form
SYSTEMS: Organs working together
ORGANISM:
Body Systems
*Protection, Support, Movement
INTEGUMENTARY: skin associated structures, skin, hair, nails, sweat and oil glands
SKELETAL: basic framework, 206 bones and joints
MUSCULAR: attached to bones to provide movement of skeleton. give structure, protect organs, maintain posture.
*Coordination and Control
NERVOUS
ENDOCRINE: controls us w hormones
*Circulation and Immunity
CARDIOVASCULAR: heart and blood vessels
LYMPHATIC
*Energy supply and fluid balance
RESPIRATORY
DIGESTIVE (oxygen needed to burn food)
URINARY
*Production of Offspring
REPRODUCTIVE
Muscle Types
Smooth - in walls of body organs
Cardiac - make up wall of heart
Anatomy
Study of the body structure
Physiology
study of body function
Pathology
study of disease
Adrenaline (synonym)
Epinephrine

Head
2 types of metabolism
Catabolism: breaks down substances (glucose to ATP, C6H12O6)
Anabolism: builds up substances (anabolic steroids)
Proximal (pic)
close to joint/point of origin
Homeostasis
Body regulating itself to a state of balance
NEGATIVE FEEDBACK: temp^ sweat|, blood sugar| glucogen^
POSITIVE FEEDBACK: body creates more of the same reaction. During childbirth body produces oxytocin to encourage contractions
Distal (pic)
farthest away from point of origin
Superior vs Inferior
Up vs Down
Anterior (Ventral) (pic)
front
Anterior vs Posterior
Ventral vs Dorsal
Posterior (Dorsal) (pic)
back
Medial vs Lateral
Towards middle vs outer side of body
Medial (pic)
towards center of body
Proximal vs Distal
Closer to origin vs further from origin, joint
Lateral (pic)
towards outside of body
Body Cavities
DORSAL: cranial, spinal
VENTRAL: thoracic, abdomenopelvic
THORACIC: periacardial, pleural, mediastinum
