The total amount of blood in your body is called
blood pressure.
blood viscosity.
blood volume.
heart rate (pulse).
The amount of force placed on the walls of your arteries as your heart pumps is called
blood pressure.
blood volume.
blood viscosity.
heart rate (pulse).
Viscosity refers to the thickness of blood.
True
False
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
True
False
Pressure on the walls of the artery due to high blood pressure (hypertension) can lead to
blood vessels decreasing in size
blood vessel diameters to decrease
tears in the blood vessel
tears in the pulmonary area
Hypertension is
brain embolism
high blood pressure
atherosclerosis
blood viscosity
As plaque build up occurs, arteries get
more elastic
shorter
more narrow
wide open
If blood viscosity increases, then blood flow ____________
increases
moves faster
decreases
stops, starts, stops
A pathogen is
a disease
a disease-causing plant
a disease-causing animal
a disease-causing microorganism (bacteria, virus)
What do antibodies bind to?
antigens
antitoxins
phagocytes
lymphocytes
True or false: an allergic reaction is a response to something that would be harmful to your body no matter what.
True
False
What is a function of the IMMUNE system?
To transport materials like oxygen to our cells
To break down food and absorb the nutrients
To fight off diseases with white blood cells
To control the body using the brain

Vaccinations will
give you a deadly disease

Each antibody is specifically made to attach to only one type of antigen
True
False
Antibiotics
only destroy bacteria

can destroy both bacteria and viruses
Vaccines work because they
make your body produce memory cells
give you antibodies directly
give you hydration
give you the disease

By consuming them
By wrapping them up in protein strings
By releasing antigens
By ANY MEANS NECESSARY
