Building Blocks of the Human Body
206 bones of different shapes and sizes
compose the adult skeleton;
but did you know that as a newborn, your
skeleton was composed of 300 bones?
For example, a newborn’s skull has eight
separate bone segments, while an adult’s
skull is composed of only four. As an adult,
bones have joined together leaving you
with only 206 bones.

Tissues
Very loud sounds can rip ear, lung and
other vibrating tissues.
A sound wave is a pressure wave; that's
why you can sometimes feel your body
vibrate during loud, low sounds.
When body tissues resonate with the
sound's frequency, the pressure
increases.
Organs

•
•
specific functions
Composed of 2 or more different tissues
Skin is the body’s largest organ

The Nervous System
The Peripheral Nervous System
• Composed of sensory and motor nerves extending
from brain and spinal cord to other parts of body
Nerve Cells (neurons)
• Have nucleus, cytoplasm and membrane
• Long and short threadlike fibers called
axons extend from nerve cells
• Nerve terminals
– located at the end of axons
– send messages as impulses
– short fibers called dendrites receive
messages

The Nervous System
Types of Nerves
• Sensory
– Afferent
– Carry messages to brain and spinal cord
– Sense of smell, sight, touch, hearing, taste
• Motor
– Efferent
– Carry messages from brain to muscles
• Mixed
– Perform both sensory and
motor functions

•
Largest of cranial nerves
Transmits facial sensations to brain
Controls the muscle movements of chewing
Divides into three main branches:
– Ophthalmic
– Maxillary
– Mandibular

The Trifacial Nerve
• Ophthalmic
– Main nerve branch to the top 1/3 of face
• Maxillary
– Main nerve branch to the middle 1/3 of face
– Divides further into zygomatic and infraorbital
• Mandibular
– Main nerve to the lower 1/3 of the face
– Divides further into auriculo temporal

• Emerges from brain at the lower part of ear
• Primary motor nerve of the face
• 6 branches are of particular importance
– Posterior Auricular - extends to muscles
behind and below ear
– Temporal - extends to muscles of temple,
side of forehead, eyebrow, eyelid and
upper cheek
– Zygomatic – extends to upper muscles
of cheek

The Digestive System
Breaks food down into simpler chemical
compounds easily absorbed by cells or
eliminated from the body in waste products
1. Enzymes from salivary glands start breaking
down food
2. Food travels down pharynx and
through esophagus
3. Food is propelled into stomach by twisting
and turning of esophagus (peristalsis)
4. Food is broken down by hydrochloric
acid and enzymes
Chapter 3.2
Anatomy and Physiology
Basic Body Systems
The Digestive System
5. Food passes from stomach into small intestine
6. Nutrients are absorbed by villi
7. Undigested food passes into large intestine
The entire digestive process takes about 9 hours
Happiness and relaxation
promote good digestion.

Beyond the Book
Digestive System
Food is able to reach your
stomach even when you are
standing upside down.
The Excretory System
•
Eliminates solid, liquid and gaseous waste products from
the body
Organs of excretory system include:
• Skin
– Body’s largest organ; releases water, carbon dioxide
and other waste through sweat glands
• Liver
– Neutralizes ammonia from circulatory system and
converts it to urea
• Kidneys
– Receive urea from liver
– Nephrons filter out waste and water
– Excreted waste products travel through
Chapter 3.2
ureters and bladder, eliminated in urine
Anatomy and Physiology
Basic Body Systems
Beyond the Book
Excretory System
Three of the four major metabolic
wastes produced by the body are
filtered from the blood by the kidneys.
They are water, salts, and urea; these
are the same three wastes that sweat
glands filter and excrete. Sweat and
urine are basically made from the
same ingredients.
The Respiratory System
•
Primary Functions
– Intake of oxygen
– Exhalation of carbon dioxide
•
•
Primary organs are lungs
and diaphragm
Breathing through the nose
is a healthier option than
breathing through the mouth
Chapter 3.2
Anatomy and Physiology
Basic Body Systems
The Respiratory System
• Lungs
- process oxygen for
absorption into the blood
and release carbon
dioxide.
• Diaphragm
- expands and contracts
automatically, forcing air
into and out of the lungs.

Beyond the Book
Respiratory System
Seventy-eight percent of the air we
breathe in is nitrogen, twenty-one
percent is oxygen, one percent is
argon and other waste gasses, and
0.033 percent is carbon dioxide.
The Endocrine System
•
•
•
•
Composed of ductless glands that regulate and
control growth, reproduction and health of body
The glands manufacture hormones
Nutrition plays a key role in proper regulation of
this system
Affects hair growth, skin conditions, energy levels
– Signs of fatigue or changes in hair growth may
signal need for medical attention

The Reproductive System
• Responsible for process by which a living
organism procreates others of its kind

• The two primary glands are
– Sebaceous (oil) glands
– Sudoriferous (sweat) glands
