Intro to Anatomy Flashcards
11 organ systems
- Integumentary
- Skeletal
- Muscular
- Nervous
- Endocrine
- Cardiovascular
- Digestive
- Urinary
- Lymphatic
- Respiratory
- Male reproductive
- Female reproductive
Integumentary system
- Encloses internal body structures
- Site of many sensory receptors
Skeletal system
- Supports body
- Enables movement (w muscular system)
Muscular System
- Enables movement
- Helps maintain temperature
Nervous system
- Detects and processes sensory info
- Activates bodily responses
Endocrine system
- Secretes hormones
- Regulates bodily processes
Cardiovascular system
- Delivers oxygen and nutrients to tissue
- Equalises temp in body
Digestive system
- Processes food for use by body
- Removes waste from undigested food
Urinary system
- Controls water balance in the body
- Removes wastes from blood
Lymphatic system
- Returns fluid to blood
- Defends against pathogens
Respiratory system
- Removes Co2
- Delivers oxygen
Male reproductive system
- Produces sex hormones and gametes
- Delivers to female
Female reproductive system
- Produces sex hormones and gametes
- Supports foetus till birth
- Produces milk for infant
4 types of tissue
- Connective tissue
- Muscle tissue
- Nervous tissue
- Epithelial tissue
Connective tissue
Binds cells and organs of the body together
Muscle tissue
Provides movement
- Skeletal, smooth and cardiac
Nervous tissue
Allows propagation of electrochemical signals in form of nerve impulses
Epithelial tissue
Sheets of cells that cover exterior surfaces of the body
Anatomical position
Upright, feet shoulder width apart, toes forward, arms held to the side and palms face forward
Anterior
Describes the front or direction toward the front of the body
Posterior
Describes the back or direction toward the back of the body
Superior
Describes a position above or higher than another part of the body proper
Inferior
Describes a position below or lower than another part of the body proper; near or toward the tail
Lateral
Describes the side or direction toward the side of the body
Medial
Describes the middle or direction toward the middle of the body
Proximal
Describes a position in a limb that is nearer to the point of attachment or the trunk of the body
Distal
Describes a position in a limb that is farther from the point of attachment or the trunk of the body
Superficial
Describes a position closer to the surface of the body
Deep
Describes a position farther from the surface of the body
Increasing complexity of structures of the body:
- Subatomic particles,
- atoms, molecules,
- organelles, cells,
- tissues,
- organs,
- organ systems,
- organisms and
- biosphere
