How could something like ashma affect your respiratory system from working properly? (p. 916)
It may not allow enough oxygen to be absorbed, and the respiratory system will have to work harder to aquire oxygen.
100
Oxygen is transported in the body by what type of cell? (p.915)
Red blood cell

What is the purpose of a scab formed on your skin?
Creates a barrier between bacteria on the skin and the tissues below

A main function of the body's systems is to maintain a stable environment, which is known as....
Homeostasis

The peripheral nervous system is composed of all of the neurons in the body that are not locacted in the brain and spinal cord. The peripheral nervous system is composed primarily of what type(s) of neurons? (p. 885)
sensory and motor neurons
200
What specific part of the lungs does gas exchange take place? (p. 914)
alveoli
200
Vessels that are known for moving blood away from the heart are called.... (p. 913)
arteries

What type of cells are sent to a wound site to battle infection?
White blood cells

Pulling your hand away from a hot stove or blinking when something is thrown at you are examples of?
reflexes
300
These types of neurons are responsible for receiving the initial stimulus into the nervous system. (p. 877)
Sensory neurons

When you exercise, your need for Oxygen rises. How do your respiratory and circulatory systems react to maintain homeostasis in your body? (p. 911-913)
Brain signals breathing and heart rate to increase
300
How does the circulatory system keep oxygen-poor and oxygen-rich blood separate? (p.913 and 917)
Separate chambers in the heart as well as arteries and veins keep the oxygen-poor blood from mixing with oxygen-rich blood.

Tetanus bacteria killed by heat or chemical treatment are injected into the body. This is an example of a(n)
vaccine

Name the four main parts of the circulatory system. (p.912-913)
Heart, arteries, veins, and capillaries.

Compare the nervous systems way of communicating with the endocrine systems way of communicating. (p. 874)
The nervous system is faster because it is a physically connected network of cells.
The endocrine system is slower becuase it is a collection of physically disconnected organs that send their messages through the blood stream (circulatory system)

What are the 6 main parts of the respiratory system (two are the entrances)? (p.911-912)
nose and mouth, epiglottis, trachea, lungs, and diaphragm
400
Why might it be important to know your blood type? (p. 927)
If you ever need to give or receive blood, knowing your blood type can prevent an imcompatible mixing of blood types which can result in death.
400
Antibodies recognize and bind to.... (p. 951)
antigens
400
What is the difference between HIV and AIDS? (p.961 and 963)
HIV is a virus that affects the immune system by reproducing in and destroying T cells.
AIDS is a deficient or worn out immune system with very little T cells
500
What are the main three parts of a neuron? (p. 876)
Cell body, dendrites, and axon
500
How does Emphysema destroy your lungs? (p.916)
Caused by smoking, and it destroys the alveoli which are needed for gas exchange.
500
How do the repiratory and circulatory systems work together? (p. 910)
Your respiratory system allows your circulatory system to pick up oxygen and deposit excess carbon dioxide.
500
Why is it that the common cold is so difficult to prevent and cannot be treated with antibiotics?
It is caused by a viral infection.
Remember: Antibiotics only treat bacterial infections
500
Individuals with HIV sometimes contract a pneumonia infection that is rare in the rest of the population because...
(p.963)
Their immune system is unable to fight off the pneumonia causing organisms
