|
Artery
|
A blood vessels that carries blood away from the heart to the other parts of the body
|
|
|
Capillary
|
the smallest blood vessels
|
|
|
Vein
|
the blood vessel that carries blood from the cells back to the heart
|
|
|
Valves
|
Flaps that act like doors to keep the blood flowing in one direction
|
|
|
Red Blood Cells
|
Shaped like discs with a dimple on each side.
They carry oxygen to the rest of the body. |
|
|
Sickle-cell Anemia
|
a disease in which the red blood cells have a shape like a crescent moon. These cells do not carry oxygen as well as a normal cell.
|
|
|
Platelets
|
They are not complete cells.
They from blood clots |
|
|
Embolism
|
An embolism is a clot that floats freely in the blood vessels and then blocks a vessel
|
|
|
White Blood Cells
|
White blood cells have different shapes and sizes. They protect your body from germs and other harmful things.
|
|
|
Leukemia
|
is a cancer when a persons white blood cells do not form correctly and their numbers increase to quickly.
|
|
|
If you fell and scraped your knee, how would white blood cells and platelets work together to protect you?
|
The white blood cells would fight any bacteria trying to get in your body and the platelets would form clots to help stop the bleeding.
|
|
|
Why are capillary walls thin?
|
The capillary walls are thin so gas can pass through the wall. Oxygen can get to the cells and Carbon Dioxide and other wastes can pass through the other direction.
|
|
|
The job of the veins and an arteries are the same and how are they different?
|
They both carry blood. The veins carry blood back to the heart and arteries carry the blood away from the heart to the cells.
|
|
|
Right Atrium
|
the right atrium relaxes it fills with blood carrying waste and carbon dioxide from the body's cells.
Then it contracts and squeezes the blood to the Right Ventricle |
|
|
Right Ventricle
|
the right ventricle contracts, pumping the blood into an artery leading to the lungs
|
|
|
Left Atrium
|
the blood flows from the lungs into the left atrium. The left atrium squeezes the blood into the left ventricle.
|
|
|
Left Ventricle
|
The left ventricle pumps oxygen rich out to the cells in the body, through the body's largest artery called the Aorta.
|
|
|
Valves
|
the valves in your heart keep the blood flowing in one direction.
|
|
|
Mucus
|
is a sticky, thick fluid that traps dust germs and other things in the air.
|
|
|
Trachea
|
a tube that carries air from the larynx to the lungs
|
|
|
Bronchioles
|
Small tubes in the lungs
|
|
|
Air Sacs
|
Thin walled pouches in the lungs where oxygen enters the blood and carbon dioxide leaves the blood.
|
|
|
Cilia
|
tiny hair like structures in the respiratory system to help clean the air by waving rapidly. This waving cause the particles to be trapped in the mucus.
|
|
|
What is the order structures that oxygen passes through between your nose and bloodstream?
|
Oxygen passes through the sinus. Then the larynx and into the trachea, through the bronchi into the lungs. Then bronchioles to the Air sacs into the bloodstream.
|
|
|
Describe how the respiratory and circulatory systems work together?
|
The two systems work together bringing oxygen into the body and getting rid of the carbon dioxide and waste out of the cells.
