Question 1 of 50

Which of the following is NOT a function of the circulatory system?

1. Pumping blood throughout the body to provide tissues and organs with nutrients and oxygen.

2. Removing toxins and waste from the blood.

3. Transmitting nerve impulses between the brain and the rest of the body.

4. Transporting important hormones released from glandsto theirsites of action.

Correct

Incorrect

The circulatory system consists of the heart, blood vessels, lymph, lymph nodes, and blood. It circulates

materials throughout the entire body, providing tissues and organs with nutrients and oxygen. It is also

responsible for transporting hormones and removing waste. The nervous system is responsible for

transmitting nerve impulses that originate in the brain and coordinate action in the rest of the body.

Question 2 of 50

2. Question

Which item below is NOT a disease of the digestive system?

1. Crohn’s disease.

2. Diabetes.

3. Ulcerative colitis.

4. Diverticulosis.

Correct

The digestive system helps the body processfood. The stomach, mouth, and esophagus all participate in

food digestion. Common diseases infecting the digestive system include Crohn’s disease, ulcerative

colitis, and diverticulosis. Diabetes is a disease of the endocrine system, that impacts the release of

insulin from the pancreas.

Question 3 of 50

3. Question

Which item below best describes the primary function of the nervous system?

1. The nervous system is the center of communication in the body.

2. The nervous system is primarily responsible for helping the body breathe.

3. The nervoussystem transports blood throughout the body.

4. The nervous system helps the body break down food.

Correct

The nervous system is the body’s communication center. The body uses the respiratory system to

breathe, and blood istransported by the circulatory system. The digestive system breaks down food for

the body.

Question 4 of 50

4. Question

Which of the following is NOT an element of the respiratory system?

1. Ribs.

2. Trachea.

3. Diaphragm.

4. Alveoli.

Correct

The respiratory system uses the lungs, diaphragm, trachea, alveoli and bronchi to help the body

distribute oxygen and remove carbon dioxide. While the ribs contain and protect many of these

elements, the ribs are part of the musculoskeletalsystem, which isresponsible for providing structure,

stability and protection to the internal organs.

Question 5 of 50

5. Question

Which of the following cells is NOT part of the immune system?

1. Neurons.

2. Dendritic cells.

3. Macrophages.

4. Mast cells.

Correct

The immune system helps protect the body from bacteria, viruses, infections, and other elements that

could cause illness. Depending on the foreign element that enters the body, different cells respond to

attack the foreign element. Cellsthat contribute to this protection and response include leukocytes, or

white blood cells (eosinophils, basophils, natural killer (NK) cells, and mast cells), and phagocytic cells

(dendritic cells, macrophages and neutrophils) in addition to cells of adaptive immunity (B cells and T

cells) which are produced in the bone marrow. A neuron is a nerve cell that is central to the nervous

system and transmits nerve impulses.

Question 6 of 50

6. Question

Which of the following is NOT one of the major types of bones in the human body?

1. Dense bone.

2. Long bone.

3. Short bone.

4. Irregular bone.

Correct

The human body has five types of bones: long bones, short bones, irregular bones, flat bones, and

sesamoid bones. While bones may be dense, this is not a major category of bones in the body.

Question 7 of 50

7. Question

Which of the following bone types is embedded in tendons?

1. Long bones.

2. Sesamoid bones.

3. Flat bones.

4. Vertical bones.

Correct

Sesamoid bones are embedded in tendons. Vertical bones, is not a major bone type. Long bones contain

a long shaft, and flat bones are thin and curved.

Question 8 of 50

8. Question

Two nursing students will be completing a scientific experiment measuring the mass of chewed gum

after one-minute chewing increments. Which lab equipment will the students most likely use?

1. Triple beam balance.

2. Anemometer.

3. Hot plate.

4. Microscope.

Correct

A triple beam balance would be used to measure the mass (in grams) of the gum in this experiment. An

anemometer is used to measure wind speed. A hot plate is used to heat liquids. A microscope is used to

magnify microscopic particles or organisms.

Question 9 of 50

9. Question

Which of the following is not a product of respiration?

1. Carbon dioxide.

2. Water.

3. Oxygen.

4. ATP.

Correct

In respiration, the human inhales air, consisting of oxygen, and then produces energy (ATP) and exhales

nitrogen, carbon dioxide, and water (in the form of vapor). While oxygen is a main component of the

respiratory system’s process, it is not produced by the respiratory system. Rather, it is utilized and

distributed throughout the body, and then what is not absorbed, is exhaled back into the environment.
