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 glands to their sites 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.

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 process food. 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 53
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 nervous system 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 is transported by the circulatory system. The digestive system breaks down food for
the body.
Question 4 of 53
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 musculoskeletal system, which is responsible for providing structure,
stability and protection to the internal organs.

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. Cells that 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.

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 53
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.
