The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?
A. A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
B. A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.

Although vaccines cannot be used to treat a person who is sick, they can help to prevent infections. Vaccinations tell the body to create "memory cells", which will function later to create antibodies against certain pathogens. When a person is vaccinated, what are they injected with?
live pathogens
antibodies to a disease bacterium
weakened viruses or antigens from the virus
blood from a person who has had the disease
Which of the following is the function of the cardiovascular system?
transporting oxygen and nutrients to cells and taking away wastes
mounting a response to invading pathogens
sending messages around the body
making enough blood for your body
What causes blood pressure?
removal of oxygen from the blood
cholesterol in the blood
stress that exercise puts on heart muscle
contraction of the ventricles in the heart
Many pathogens have become resistant to antibiotics because antibiotics have been so widely used. Now, pathogens that used to be killed by antibiotics are more difficult to treat. What is the best way to proceed in dealing with this public health problem?
Antibiotics should no longer be used.
Antibiotics should only be prescribed to people with bacterial infections.
Anti-viral medications should now be used instead of antibiotics.
Antibiotics should only be prescribed to people with viral infections.
The point at which the umbilical cord attaches to the fetus becomes the belly button after birth. What is the function of the umbilical cord for mother and fetus during fetal development?
Nutrients from foods digested by the mother and oxygen pass from her blood to the fetus through blood vessels in the umbilical cord.
Part of any food consumed by the mother passes from the mother’s stomach, through the umbilical cord, and into the stomach of the fetus.
Waste products produced by the fetus travel through the umbilical cord and out through the mother’s kidneys.
Liquids consumed by the mother flow through the umbilical cord and into the stomach of the fetus.
An activity that occurs in the human body is shown below.
