HUMAN ORGAN SYSTEMS
SYSTEM
- A several organs that works together.
SKELETAL SYSTEM
- Bones protect your internal organs and support your body as you stand, sit, walk, and run.
Provides shape & support
Helps you move
Protects organs
Produces blood cells
Stores certain materials
Protects internal organs:
Skull
- protects the brain
Ribs
- protect the heart & lungs
Vertebrae
- protects the spinal cord
Femur
- produces blood cells in the leg
Humerus
- produces blood cells in the arm
MUSCULAR SYSTEM
It functions to
A.
Help the body move
B.
Move food through the digestive system
C.
Keep the heart beating
MUSCLES ACTION
-
Involuntary
(muscles not under your control.) -
Voluntary
(muscles that are under your control.)
3 Types of Muscle Tissue
Skeletal
(attached to bones & move bones)
Smooth
(inside many internal organs)
Cardiac
( found only in heart)
INTEGUMENTARY SYSTEM
It
Covers
and protects the body to prevent water loss and keep out foreign particles.
Keeps
you in touch with the environment (nerve endings)
Regulates
your body temperature
Gets rid of wastes (sweat/perspiration)
EPIDERMIS
Outermost
layer
No
nerves or blood vessels
Surface
is made of dead cells (provide protection)
DERMIS
- Lower layer of the skin
Contains nerves, blood vessels, sweat glands, hairs & oil glands
DIGESTIVE SYSTEM
- made up of many important organs that work together to digest the food you eat. It also helps your body absorb all the nutrients that the food contains. Nutrients are substances that keep you healthy.
Breaks down food into molecules the body can use.
Molecules are absorbed into the blood & carried throughout the body (by the circulatory system).
Wastes are eliminated from the body (by the excretory system)
RESPIRATORY SYSTEM
- helps your body take oxygen from the air. The respiratory system is made up of your nose, mouth, trachea, lungs, and diaphragm
Moves oxygen from the outside environment into the body.
It also removes carbon dioxide and water from the body.
CIRCULATORY SYSTEM
- comprising the heart, blood vessels, and blood, transports oxygen and nutrients throughout the body. It supports immune function and maintains organ and tissue health.
It carries needed substances to cells and carries wastes away from cells.
Heart
- muscular organ that pumps blood throughout the body.
Plasma
– liquid part of blood
Red blood cells
– take up oxygen in the lungs and deliver it to cells
White blood cells
– the body’s disease fighters (part of immune
system)
Platelets
– cell fragments used in forming blood clots (that make scabs)
NERVOUS SYSTEM
- master controller of the body.
A.
Receives information about what is happening inside and outside of the body.
B.
Directs the way your body responds to this information.
C.
Helps maintain homeostasis.
CENTRAL NERVOUS SYSTEM
Brain
- controls most functions in the body
Cerebrum
Interprets input from the senses
Controls movement of skeletal muscles
Complex mental processes (learning)
Cerebellum
Coordinates muscle actions & balance
Brainstem
(medulla)
Controls involuntary actions
Spinal Cord
- link between brain & the rest of the body
PERIPHERAL SYSTEM
Neurons
nerve cell that is specialized to transfer messages in the form of fast-moving electrical energy
electrical messages are called impulses
IMMUNE SYSTEM
Provides a barrier against pathogens (disease-causing agents).
Defends the body against pathogens.
First line of defense
: barrier
Second line of defense
: inflammatory response
Third line of defense
: The immune system targets specific pathogens
ORGAN
- A group of tissues forms
Kidney
Eliminate urea, excess water, & some other waste materials
Filter wastes from the blood
Produce urine
Anus
- Removes solid wastes from digestive system
Lungs
- Remove carbon dioxide produced during cellular respiration
Skin
- Removes perspiration (dissolved waste materials)
ROLES OF ORGAN
Mouth
– mechanical & chemical digestion starts here
Mechanical
– physically breaking down food (teeth)
Chemical
– breakdown of molecules of food (saliva)
Esophagus
– the muscular tube connecting the mouth to the stomach
Peristalsis (muscle contraction) moves the food
Stomach
- Most mechanical digestion takes place
Some chemicals with the help of digestive juices (enzymes & acids)
Small Intestine
Most of the chemical digestion takes place
Absorption of nutrients from digested food into the bloodstream
Large Intestine
Water is absorbed into the bloodstream
Remaining material is readied for elimination from the body
Rectum
Waste material is compressed into solid form
TISSUES
- A group of similar cells having similar functions form
