Body Systems
{
Dividing the body
Provides all body systems
with oxygen and nutrients
Carries away carbon
dioxide and other wastes
Circulatory System
Consists of:
Blood (oxygen source for the body)
Heart (pumps blood throughout the body)
Arteries (carry blood away from heart)
Veins (carry blood to the heart)
…. Continued
Systolic (peak pressure in the arteries)
Diastolic (minimal pressure in arteries)
Blood Pressure
Digestive System
Breaks down
food into
chemicals that
the body can
use for energy
and to maintain
cells and tissues
Consists of:
Liver (detoxification and protein synthesis)
Stomach (1st step of digestion after chewing)
Small Intestine (where MOST digestion takes
place)
Large Intestine (absorbs water and pass useless
waste through the body)
Digestive System
Carries
oxygen from
the air to the
bloodstream
and rids the
body of
carbon
dioxide
Respiratory System
Consists of:
Lungs
Bronchi (trachea to lungs)
Bronchial tubes (bronchi to
alveoli)
Alveoli (lungs to bloodstreamgas exchange)
Respiratory System
Gathers information from the external
environment, stores and processes it, and
initiates appropriate responses
Nervous System
Consists of:
Axon
Dendrite
NeuronProcesses and
transmits
information by
electrical
signaling
Brain- Controls
all senses
Nervous System
Central Nervous SystemBrain and Spinal Cord
Peripheral Nervous
System- Connects the body
to the CNS
Nervous System
Components
Cerebrum- Largest part of the brain. Controls
all senses and emotions
Cerebellum- Second largest. Controls muscle
coordination, balance, and posture
Brainstem- Connects to spinal cord. Controls
heart rate, blood pressure, and breathing
Brain
Skeletal System
Provides the framework and protection for the body
The typical human body has 206 bones
A place where two bones connect is called a
joint.
Pivot
Ball and Socket
Skeletal and Muscular
System
Hinge
Types of Muscle
SMOOTH- makes up your internal organs
(stomach and intestine)
CARDIAC- (you better know)
SKELETAL- muscle that attaches bone to bone
