12. The Eleven Systems of Human
Physiology: Murders, Inc. I
M is for Muscular System
U is for Urinary System
R is for Respiratory System
D is for Digestive System
E is for Endocrine System
R is for Reproductive System
S is for Skeletal System
I is for Integumentary system
N is for Nervous System*
C is for Circulatory System*
I is for Immune System
VI-3B
13. The body has three different
Muscular System
kinds of muscles
The heart, or cardiac muscle
Smooth muscles, which control the
body’s involuntary operations
Striated muscles, which carry out
our voluntary movements
14. Urinary System
• This system consists of two
•
kidneys, the bladder, ureters
connecting the kidneys to the
bladder, and the urethra, which
transports the urine out of the
body
Kidneys filter waste or harmful
products, such as drugs and their
metabolites, from the blood, and
dump these waste products into
the bladder. What the Hell is a
metabolite?
15. Respiratory System
The major parts of the Respiratory System are
the lungs and the diaphragm
The diaphragm is a smooth muscle that draws
the air into the lungs and forces it out
Lungs take oxygen and transfer it to the blood,
and remove carbon dioxide and some other
waste products from the blood, and expel
them into the outside air
16. Digestive System
Major components of this system are the
tongue, teeth, esophagus, stomach, intestines,
liver and pancreas
The Digestive System breaks down large
particles of food, until they are of a size and
chemical composition that can be absorbed in
the blood
17.
18. Endocrine System
• The Endocrine System is made up of a number
•
•
of different glands, that secrete hormones
Hormones are complex chemicals that travel
through the blood stream and that control or
regulate certain body processes
Some drugs can mimic the effects of
hormones, or can react with the hormones in
ways that alter the hormones’ effects
19. Reproductive System
The functions of the
Reproductive System fall into
two roles 1. Self producing
(cytogenic) 2. Hormone
producing (endocrinic)
We are primarily concerned
with hormone production
since the hormones produced
by the Reproductive System
aid the nervous system in its
regulatory role
20. Skeletal System
Consists of bones, cartilage and ligaments
The Skeletal System provides support to the
body, permits movement, and forms blood
cells
It is however, affected by drug abuse, we just
may not be able to see it
22. Integumentary System
Consists of skin, hair, finger and toe nails, and
accessory structures
The chief functions of the Integumentary
System include protection of the body, control
of body temperature, excretion of wastes (i.e.
through the sweat) and sensory perception
24. Nervous System
This system consists of the brain, the
brain stem, the spinal cord and the
nerves
Nerves keep the brain informed of
changes in the body’s external and
internal environments
Nerves also carry messages from the
brain to the body’s muscles, tissues and
organs
The Nervous System controls,
coordinates and integrates all
physiological process, so the normal
body functions can be maintained
25. Circulatory System
•
•
•
•
•
For our purposes, the Circulatory
System consists of the heart, the blood
vessels (veins and arteries), and the
blood
Blood carries food, water, oxygen,
hormones, antibodies etc. to the
tissues and organs
Blood also carries heat through the
body
Blood is the main carrier that brings
drugs to the brain
The heart pumps and forces the blood
to circulate through the body
26. IMMUNE SYSTEM
The immune system protects against disease
by destroying “foreign” cells and by
inactivating toxins and other foreign chemicals
with its antibodies.
27.
28. Homeostasis
• The human body is exposed to constantly
changing external environment.
• Changes are neutralized by the internal
environment – the blood
• Oxygen, foods, water and other substances are
•
•
constantly leaving body fluids to enter cells,
while carbon dioxide and other wastes are
leaving the cells to enter these fluids
Yet the chemical composition of these fluids
remains within very narrow limits
This phenomenon is called homeostasis
29. Homeostasis: is the key to drug use: the body is out of
balance
Dynamic balance or steady state involving
levels of salts, water, sugars and other material
in the body’s fluids

40. Fundamental Notions
If something interferes with the messages to
the brain sent along the motor nerves, the
brain’s control over the heart, the lungs, the
muscles and other organs will be distorted
If something interferes with the messages the
brain receives from the sensory nerves, the
brain’s perception of the outside world and of
the body’s status will be distorted
THIS IS HOW DRUGS WORK ON THE
FUNCTIONING OF THE NERVOUS SYTEM
41. Motor Nerves
• There are two sub-systems of motor nerves:
– The voluntary nerves send messages to the striated
–
muscles that we consciously control
The autonomic nerves send messages to the
muscles and organs that we do not consciously
control, i.e., smooth muscle and cardiac muscle
42. The Autonomic Sub-System
• The Autonomic Sub-System divides into two
groups:
– First, the Sympathetic nerves command the body
to react in response to fear, stress, excitement,
etc.
•
“Fight or Flight” Responses:
– Blood pressure elevated
– Pupils to dilate
– Sweat glands to activate
– Hair to stand on end
– Heart beat to increase and strengthen
– Blood vessels of the skin to constrict
– Inhibited digestion
43. The Autonomic Sub-System
• Second, the Parasympathetic nerves carry
messages that produce relaxed and tranquil
activities
– Pupils to constrict
– Heartbeat to slow
– Peripheral blood vessels to dilate
– Blood pressure to decrease
– Digestion to be facilitated
44. Drugs & the Autonomic SubSystems
• Some drugs mimic the neurotransmitters that
•
•
travel in the Sympathetic and Parasympathetic
nerve systems
Drugs that mimic neurotransmitters in the
Sympathetic system are called
Sympathomimetic drugs. These drugs will
artificially create the same effects.
Drugs that mimic neurotransmitters in the
Parsympathetic system are called
Parasympathomimetic drugs. These drugs will
artificially create the same effects.
45. A Simplified Concept of a Nerve
The nerves that carry messages to
and from the brain often are
pictured as “wires” or “telephone
wires” that carry electrical signals
A more accurate, but still simplified
concept would envision a nerve as
a series of broken wire segments,
with the segments separated by
short spaces, or gaps
