In which of the following organs does digestion begin?
A. Mouth
B. Stomach
C. Small intestine
D. Pancreas - ANS :A. Mouth
In which of the following organs does the breakdown of proteins begin?
A. Mouth
B. Stomach
C. Small intestine
D. Pancreas - ANS :B. Stomach
Which of the following structures absorbs nutrients in the
small intestine?
A. Mucus
B. Microvilli
C. Enzymes
D. Hormones - ANS :B. Microvilli
Which of the following statements best describes peristalsis?
A. The partly digested food moving from the stomach to the small intestine.
B. The mechanical breakdown of food entering the stomach.
C. Muscle contractions that move food through the digestive tract.
D. chemical digestion of food with the help of enzymes. - ANS :C. Muscle contractions that move food through the
digestive tract.
I'm a well-structured paragraph, describe the mechanical and chemical digestion of a starch or carbohydrate. - ANS
:Starch begins to breakdown in the mouth. Chewing breaks the food fragments into smaller pieces. Amylase chemically
speeds up the process of starches breaking down into smaller
molecules. Muscle contractions in the stomach break down food particles into chyme. Then, in the small intestines, more
enzymes released by the pancreas break down the starches into simple sugars.
Which of the following actions are controlled by voluntary nerve signals? (Select all that apply.)
A. Walking
B. Digestion

C. Talking
D. Heart beating
E. Breathing - ANS :Walking and talking
Which of the following best describes the function of a nerve synapse?
A. It carries a nerve impulse away from the nerve body.
B. It is responsible for involuntary muscle movements.
C. It allows for the passing of signals between neurons and other neurons or between neurons and muscles.
D. It contains a bundle of fibers that transmit electrical
impulses. - ANS :C. It allows for the passing of signals between neurons and other neurons or between neurons and
muscles.
Which of the following describes the role of the central nervous system?
A. It transmits electrical signals to muscles.
B. Transmits sensory information
C. It controls the regulation of body systems.
D. It sends messages from the body to the spinal cord. - ANS :C. It controls the regulation of body systems.
Which of the following types of nerves sends messages to the brain?
A. Skeletal
B. Smooth
C. Sensory
D. Motor - ANS :C. Sensory
In three to five sentences, describe the differences between the central nervous system and the peripheral nervous
system. - ANS :The central nervous system is comprised of the brain and spinal cord. It controls the regulation of body
systems. The peripheral nervous system is made up of all of the neurons that connect the
central nervous system to the rest of the body. It is responsible for sending the messages to the brain or from the brain to
designated targets.
Which of the following are the thick filaments in a muscle cell?
A. Actin
B. Myosin
C. Myofibrils
D. Sarcomere - ANS :B. Myosin
Which of the following best describes the role of tendons?
A. They connect muscle to bone.
B. They connect bone to bone.
C. They connect tendons to muscles
D. They connect cartilage to bone. - ANS :A. They connect muscle to bone.
Which of the following types of muscle tissue is voluntary?
A. Skeletal
B. Smooth
C. Cardiac
D. Nervous - ANS :A. Skeletal
Which of the following muscles are located at the shoulder?

A. Deltoids
B. Pectorals
C. Trapezius
D. Abdominals - ANS :A. Deltoids
A person puts his hand on a hot stove but quickly removes it. In three to five sentences, describe the pathway of the
signal and response through the nervous system. - ANS :Muscles are connected to nerve fibers. The hot stove is felt, and
a message is sent to the brain. The nervous system sends a signal back to the muscles. The receptors in the muscles of
the hand and arm receive the signal and respond. This causes the muscles to contract and move the hand away.
Afferent nerves carry the hot sensation to the brain. Efferent nerves carry neurotransmitters which synapse with muscles
of the hand which cause them to contract, removing the hand.
Which of the following organs produce female gametes?
A. Ovary
B. Testes
C. Prostate
D. Uterus - ANS :A. Ovary
Which is the location where fertilization typically takes place?
A. Vagina
B. Penis
C. Vas deferens
D. Fallopian tubes - ANS :D. Fallopian tubes
Which of the following best describes one function of estrogen?
A. Production of sperm cells
B. Maturation of eggs
C. Implantation
D. Fertilization - ANS :B. Maturation of eggs
Which of the following result from the production of luteinizing hormone (LH) in males? (Select all that apply)
A. Heart growth
B Facial hair growth
C. Testosterone production
D. Sperm production - ANS :B Facial hair growth
C. Testosterone production
D. Sperm production
In three to five sentences, describe how the production of male and female gametes differs. - ANS :Male gametes, or
sperm, are produced by the testes, whereas female gametes, or eggs, are produced by the ovaries. Sperm are constantl
produced, but eggs are developed and matured cyclically. Eggs are typically released one at a time, but many sperm can
be released at once during ejaculation.
Which of the following is the layer of skin that forms a protective, waterproof barrier?
A. Dermis
B. Sudoriferous
C. Sebaceous
D. Epidermis - ANS :D. Epidermis
