14 Voluntary Skeletal Skeletal Attached to bone Attached to bone Form the major muscle mass Form the major muscle mass Under control of the nervous system and brain Under control of the nervous system and brain Can be contracted and relaxed at your will Can be contracted and relaxed at your will Responsible for movement Responsible for movement

15 Involuntary Smooth Smooth Found in the GI tract, urinary system, blood vessels and bronchi Found in the GI tract, urinary system, blood vessels and bronchi Control the flow of blood Control the flow of blood Carry out the automatic muscular functions Carry out the automatic muscular functions No direct control No direct control Respond to stretching, heat and cold Respond to stretching, heat and cold

16 Cardiac Found only in the heart Found only in the heart Involuntary Involuntary Own supply of blood; coronary artery system Own supply of blood; coronary artery system Can tolerate interruption for very short periods Can tolerate interruption for very short periods Automaticity: Ability of muscles to contract on their own Automaticity: Ability of muscles to contract on their own

42 Function

43 Organs of Digestion Stomach Stomach Small intestine Small intestine Stomach: Hollow organ; expands as it fills with food Stomach: Hollow organ; expands as it fills with food Small intestine: Hollow organ where food absorption takes place; Divided into 3 parts: Duodenum, jejunum, ileum Small intestine: Hollow organ where food absorption takes place; Divided into 3 parts: Duodenum, jejunum, ileum Large Intestine; hollow organ; removes water from waste products Large Intestine; hollow organ; removes water from waste products

46 Ileum: The function of the ileum is mainly to absorb vitamin B12 and bile salts and whatever products of digestion were not absorbed by the jejunum.
