A doctor prescribes a blood thinner to a patient with high blood pressure. What impact will this medication have on blood flow and viscosity?
The blood flow will decrease and the viscosity will decrease.
The blood flow will decrease and the viscosity will increase.
The blood flow will increase and the viscosity will decrease.
The blood flow will increase and the viscosity will increase.
While attending a community health fair, Susan finds out that she has borderline hypertension, or high blood pressure. What lifestyle changes would help to lower blood pressure without taking prescription medications?
Adding more fried foods to the diet will provide the fats that the body needs for vessel elasticity.
Drinking less water and other fluids will increase the blood viscosity or thickness so that the heart works less.
The person should stop their training for a half marathon since demanding exercise elevates the heart rate.
Moderate exercise and relaxation techniques to lower stress levels, forces that often increase hypertension.
Cigarette smoking has many negative effects on the body including immediate changes in the cardiovascular system. Since smoking constricts or narrows blood vessels and elevates the heart rate, what effect would be linked to these differences in a smoker’s circulation?
A decrease in vessel diameter would reduce circulating blood volume, limiting oxygen to the affected cells and altering their metabolism.
Smaller blood vessels, or capillaries, would be less affected by the pressure exerted by the heart, increasing the pressure on larger blood vessels.
The brain would make homeostatic adjustments to the changes in heart rate, storing extra fat needed by the heart for its extra work.
The time needed for blood circulation would change, so blood would tend to collect in areas such as the hands and feet.
The table below shows the average blood cholesterol levels in two patients along with the average range of cholesterol levels. Which inference can most likely be made about the cardiovascular systems of Patients A and B?
Patient A has the greater chance of having collections of arterial plaque, a risk factor for high blood pressure.
Patient B has the greater chance of having collections of arterial plaque, a risk factor for high blood pressure.
Patient A should hydrate with water to increase blood
volume so that total cholesterol rises to the average range.
Patient B should increase salt intake to decrease blood
volume to that total cholesterol drops to the average range.
Many people have received the measles vaccine so that they will be protected from getting the measles, which can be very serious or even fatal. How does receiving a measles vaccine help to protect a person from getting the measles?
The vaccine prevents the virus that causes the measles from entering the body.
The vaccine inserts genes into body cells to fight the virus that causes the measles.
The vaccine adds a chemical to the body that is poisonous to the virus that causes the measles.
The vaccine causes the immune system to produce antibodies to the virus that causes the measles.
After an initial infection, B-cells recognize the measles virus. How is this helpful in human immune response?
The B-cells use this recognition to defend the body against other pathogens, such as bacteria.
The B-cells more quickly recognize and respond to any other virus that invades the body.
The B-cells produce antibodies more quickly if the measles virus is encountered again.
The B-cells transfer this recognition to T-cells, which will then devour the viruses.
You are in the middle of a pandemic. What is the body's first line of defense against infection by foreign organisms?
The skin
Antibodies
White Blood Cells
Lymph Nodes
What is the term for a strong response to a harmless antigen in the environment?
cell-mediated immunity
inflammatory response
an allergy
an autoimmune disease
Which of the following describes a way that a person's health can be affected by heredity?
A person with a family history of obesity is more likely to catch a common cold.
A person with a family history of high blood pressure is more likely to have heart disease.
A person with a family history of obesity is less likely to enroll in a weight loss plan.
A person with a family history of cancer is less likely to be screened for cancer.
How do human diseases caused by bacteria and diseases caused by viruses react to antibiotics?
Neither responds to antibiotics.
Both respond to antibiotics.
Viral diseases respond to antibiotics; bacterial diseases do not.
Bacterial diseases respond to antibiotics; viral diseases do not.
Many species of bacteria have become resistant to antibiotics because antibiotics have been so widely used. Now, bacteria 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 be made available to anyone without a prescription.
Antibiotics should only be prescribed to people with bacterial infections.
Anti-viral medications should now be used instead of antibiotics.
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 high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
The narrowing of blood vessels increases pressure and leads to a faster blood flow.
Which line in the graph best illustrates an effect of the carbon dioxide level in the blood on breathing rate before, during and after a period of exercise?
A
B
C
D
Vigorous exercise often leads to increased heart rate, as our bodies are trying to pump oxygen to our cells for energy. If we cannot provide oxygen quickly enough, what will our cells begin to do for energy?
Switch to Photosynthesis for food and then break it down for energy
Make no change and continue using aerobic respiration b/c Oxygen is optional
Switch to anaerobic respiration to make energy without the need for Oxygen
The cells will cease to have energy and will promptly die along with the host organism
Doctors and scientists group embryonic development into trimesters. Each list below shows development during one trimester, though the lists are not in chronological order.

First Trimester—2; Second Trimester—1; Third Trimester—3
First Trimester—1; Second Trimester—3; Third Trimester—2
First Trimester—3; Second Trimester—2; Third Trimester—1
First Trimester—2; Second Trimester—3; Third Trimester—1
