103
Q

central nervous system

A
  • brain and spinal cord
  • brain receives info from the body and then sends impulses to different areas of the body to respond to internal and external changes
  • key function is consciousness
104
Q

peripheral nervous system

A

-the nerves (sensory and motor) that enter and leave the spinal cord and travel between the brain and organs without passing through the spinal cord

105
Q

autonomic nervous system

A
  • the division of the peripheral nervous system that controls involuntary motor functions (i.e. digestion and heart rate)
  • can be further broken down into the sympathetic and parasympathetic nervous system
106
Q

sensory nerves

A
  • PNS
  • pick up info from throughout the body and transmit this to the spinal cord and brain
  • ex. if you touch something hot, your sensory nerves transmit this to the spinal cord and brain so immediate action may be taken
107
Q

motor nerves

A
  • PNS

- carry messages from the brain to the body

108
Q

sympathetic nervous system

A
  • function often referred to as the “fight or flight”
  • engaged when the body is in crisis
  • stimulation of sympathetic tone causes the heart to beat faster, the lungs to breathe deeper, and the blood vessels to constrict
109
Q

parasympathetic nervous system

A
  • engaged in times of relaxation and is often referred to as the feed-or-breed response
  • parasympathetic tone causes increased blood flow to the digestive tract and to the reproductive system
  • can also cause the heart to slow down and the blood vessels to dilate
110
Q

stomach

A
  • a hollow organ that expands as it fills with food

- acidic gastric juices begin to break food down into components that the body will be able to convert into energy

111
Q

small intestine

A
  • 3 parts: duodenum, jejunum, ileum
  • receives food from the stomach and continues to break it down for absorption
  • these nutrients are absorbed by the body through the wall of the small intestine
112
Q

large intestine (colon)

A
  • removes water from waste products as they move toward elimination from the body
  • anything not absorbed moves forward and is excreted as feces
113
Q

  • detoxifies harmful substances
  • stores sugar
  • assists in production of blood products
114
Q

gallbladder

A

serves as a storage system for bile from the liver

115
Q

  • as a medication, it dilates respiratory passages and is used to relieve severe allergic reactions
122
Q

kidneys

A
  • principal organs of the renal system
