The Respiratory system:

It supplies the blood with oxygen in order for the blood to deliver oxygen

to the rest of the body.

Major Organs & Structures of this

System….

The Lungs…Facts

• A pair of organs that are the site of oxygen absorption.

• They are light pink.• Full of air• They are surprisingly light.• Takes up most of the area in your chest.• It wraps around your heart.

Main FunctionRespiration- The process of oxygen entering your body, and carbon dioxide leaving your body.

The Trachea…Facts

• The trachea is also called the windpipe.

• This tube leads from the top of the neck, below the voice box, and down towards the lungs.

• It is surprisingly flexible, stretching to be 4 or 5 inches long.

• Its made up of 16 to 20 cartilage rings in the shape of a “C”.

Main FunctionThe trachea allows air to travel passed the larynx and to the bronchi.

The Bronchi…

Facts• The bronchi is the branches

of the windpipe/trachea that lead into the lungs.

• Each bronchi enters its lung and begins on a series of branches, called bronchial or respiratory tree.

Main FunctionThe bronchi conducts air into the lungs.

The Diaphragm…

Facts• A sheet of muscle underneath

the lungs of mammals that helps draw air to the lungs.

• A dome shaped muscle that moves up and down to expand or contract lungs.

Main FunctionContracts so the lungs can inhale oxygen. Then releases for the lungs to exhale carbon dioxide.

Other Important Structures….

The Alveoli…

What is it???The alveoli is inside of the lungs and is where the waste (carbon dioxide) goes so that our lungs can exhale the harmful waste. So basically it is the container of which hold carbon dioxide until it is exhaled.

Diseases That Affect This System…Pneumonia

Asthma

Chronic Bronchitis

Emphysema

Chronic Obstructive

Pulmonary Disease

Common Cold

Lung Cancer

Influenza

Sinusitis

Diseases…

So many things can go wrong with this system. The respiratory system is very vulnerable to toxins and diseases. In some cases the patient is unable to breath properly. Like with pneumonia, it causes your lungs to fill up with fluid and then you cant get enough air into your lungs.

Relationship to Other Systems…

Relationships…

The respiratory system provides the body with oxygen and supplies the blood with oxygen. Then the circulatory system sends the blood to all the other systems throughout the body. Without this system you would not be able to function or live.

Nervous System!!The nervous system is responsible for

sending, receiving, and processing new impulses throughout the body.

Major Organs/Structures…

What are they??

Central Nervous SystemBrain- Controls all thoughts

and actions, your brain is the source of everything you do.

Spinal Cord-The main nerve extending from the base of the brain along inside of the back bone.

Peripheral Nervous SystemSensory Organs-Composed of

neurons, which convert environmental stimuli to electrical signals and glia-like cells.

Motor Neurons-A neuron that carries an impulse from the brain or spinal cord to a muscle, where it simulates contractions.

Important Structures…

A Neuron…

DiseasesParkinson Disease

Alzheimer Disease

Broca Aphasia

Locked-in syndrome

Huntington disease

Wilson disease

Diseases…

Parkinson’s Disease Parkinson’s disease is a

progressive disorder that is caused by a generation of nerve cells in the Part of the brain called the substantia nigra, which controls movement. Then the nerve cells die therefore you are then unable to control movement of certain parts of your body.

Treatment The patients are treated with

medication to relieve symptoms of the disease.

Symptoms• Tremor• Involuntary movements of the

hands, arms, legs and jaw.• Unsteady walk or balance• Depression• Muscles rigidity, or stiffness of

the limbs.

Relationships to other Systems…

Relationships• Skeletal System: the brain regulates

the position of bones by controlling muscles.

• Cardiovascular System: the brain regulates heart rate and blood pressure.

• Muscular System: the brain controls contractions of muscles

• Endocrine System: the hypothalamus controls the pituitary gland and other endocrine glands.

• Lymphatic Systems: The brain can simulate defense mechanisms against infection.

• Respiratory System: the brain regulates breathing rate.

• Digestive System: Provide the building blocks for some neurotransmitters. The brain controls drinking and feeding behaviors.

• Urinary System: The brain controls urination.

• Integumentary System: Nerves control muscles connected to hair follicles.
