QUESTIONS & DETAILED ANSWERS
LATEST UPDATE. A+ GUARANTEED
1. The gall bladder is part of the __________.
A. endocrine system.
B. urinary system.
C. digestive system.
D. nervous system.
C. The gall bladder stores the fat-digesting bile produced by the liver.
2. Which is Not an example of a nonspecific immune response?
A. Inflammation.
B. Vasodilation.
C. Releases of histamine.
D. Production of antibodies
D. In nonspecific immunity, the response is immediate and antigen-independent,
meaning that the invading organism need not be identified by the body. In specific
immunity, the response takes some time and is antigen-dependent, as the production of
specific antibodies would be.
3. Which organ system is primarily responsible for regulating electrolytes?
A. The endocrine system.
B. The urinary system.
C. The lymphatic system.
D. The nervous system.
B. The body's electrolytes must be maintained at very precise concentrations. Excess
water dilutes the body's electrolytes, whereas water restriction concentrates them. The
kidneys regulate and help maintain the balance of water and electrolytes in the body.
,4. What is the function of the coronary artery?
A. It carries oxygenated blood to the heart.
B. It carries deoxygenated blood to the lungs.
C. It distributes blood to the body.
D. It supplies blood to the heart muscle.
D. Choice A describes the pulmonary vein, and choice B describes the pulmonary artery.
Most of the arteries of the body perform the function described in choice C, but the
coronary artery's main function is to feed blood to the heart muscle to allow it to pump.
5. What condition might result from lack of vitamin C?
A. Kwashiorkor.
B. Pellagra.
C. Rickets
D. Scurvy
D. Scurvy was once the disease of sailors because months at sea without fruits and
vegetables led to vitamin C deficiency. Without vitamin C, the human body cannot
synthesize collagen, leading to spongy tissue and bleeding sores.
6. How does the muscular system work with the skeletal system?
A. Muscles attached to tendons contract to bend the skeleton at the joints.
B. The hard bones of the skeleton protect the voluntary muscles of the limbs.
C. The cardiac muscles produce calcium that is needed for sturdy bones.
D. Smooth muscles on internal organs leach excess minerals from the bones.
A. Messages from the nervous system tell the muscles to contract, which in turn
moves the bones.
7. Which is Not produced by the pituitary gland?
A. FSH
B. TRH
C. LH
D. ADH
, B. FSH (choice A) and LH (choice C) regulate reproduction. ADH (choice D) promotes
water retention. TRH (choice B) is produced in the hypothalamus and releases thyroid-
stimulating hormone.
8. The ribs are ________ to the lungs in the human body.
A. medial
B. superior
C. anterior
D. deep
C. The ribs are in front of the lungs in the human body, making them closer to the front
of the body, or anterior.
9. What is the normal pH of human arterial blood?
A. 6.8
B. 7.4
C. 7.9
D. 8.2
B. The range is about 7.35 to 7.45, making blood fairly neutral. Excess carbon dioxide can
lead to acidosis, a pH below 7.35.
10. Which cut is considered a cross section?
A. A sagittal or frontal section.
B. A cut along the coronal plane.
C. A cut along the median plane.
D. A cut through the transverse plane.
D. A transverse section is a cross section; it separates the body horizontally into upper
and lower sections.
11. Which enzyme functions to break down a specific sugar?
A. Catalase.
B. Lipase.
C. Protease.
D. Lactase.
