UNIT 2 EXAM QUESTIONS AND
ANSWERS
Explain the digestive system and its role in our bodies. - ANSWER-It is the life support
of the body. It is basically a strong muscular tube lined with thick epithelium with
specialized cells that begins at the mouth and ends at the anus. It consists of the
digestive tract and glands that secrete digestive juices into the digestive tract.
Digestion is the process by which food is broken down through chemical and physical
means so that nutrients can be absorbed through the intestinal walls to adjacent blood
and lymphatic vessels. The undigested material is then eliminated through the anus)
What is maximum oxygen uptake (VO2 max) and how does it relate to exercise? -
ANSWER-It is the measurement of the maximum amount of oxygen a person can utilize
during intense exercise.
VO2 supplies your working muscles with oxygen. As your exercise intensity increases
there is an increase in muscular oxygen demands, which causes an increase in your
VO2. If you continue to increase the intensity you will eventually reach a point of
maximal exertion, which will result in your maximal oxygen consumption (VO2 max).
This is the maximum volume of oxygen that your body is capable of consuming and
converting to energy for your working muscles.
Explain the nervous system and its two major parts. - ANSWER-It is the control center
of the body and the network for internal communication. It is comprised of the brain,
spinal cord, sense organs and nerves.
One of the major parts of the nervous system is the central nervous system (CNS). This
consists of the brain and the spinal column. It receives messages, and after interpreting
them, it sends instructions back to the body.
The second major part is the peripheral nervous system (PNS). This system does two
things: It relays messages from the CNS to the body (the efferent system) and it relays
messages to the CNS (the afferent system) from the body.
Explain the relationship between the endocrine system and the nervous system. -
ANSWER-The endocrine system works with the nervous system to maintain the steady
state of the body. The endocrine system helps regulate growth, reproduction, salt and
fluid balance, use of nutrients by cells, metabolic rate, and stress regulation. The
nervous system is also important in stress regulation. The endocrine system consists of
tissues and glands that secrete chemical messengers called hormones.
, Explain the role of hormones in the body. - ANSWER-Hormones are essential to the
function of the human body. Various glands that comprise the endocrine system secrete
chemical messengers called hormones. There are two types of hormones, steroids and
polypeptides. They diffuse into the blood and course through your body and eventually
act upon a target organ to help modify and control functions. For example the testes
secrete the Testosterone Hormone in males which controls muscle size; increases
number of red blood cells; decreases body fat; and promotes male sex characteristics.
What is the role of growth hormone (HGH) in the body and how does it relate to
exercise? - ANSWER-It stimulates tissue growth; mobilizes fatty acids for energy; and
inhibits CHO metabolism.
Exercise is an effective way to significantly raise your HGH levels. HGH stimulates
tissue uptake of amino acids and the synthesis of new protein and long bone growth.
HGH stimulates cellular growth and can increase muscle protein synthesis which is
what is responsible for muscle growth. HGH also helps in regulating our metabolism.
If blood glucose levels are_________ _________ Insulin is released. - ANSWER-too
high
Insulin signals _____ ____ ________ to absorb ______. - ANSWER-fat and muscle to
absorb glucose
Insulin signals the ______ to make ________ - ANSWER-Liver to make glycogen.
If blood glucose levels are too low, __________ is released. - ANSWER-glucagon
Glucagon signals the liver to _________ _________ and ________ _________. -
ANSWER-breakdown glycogen and release glucose.
True or False
Anatomy is the science of body structure and Physiology is the science behind how our
body functions. - ANSWER-True
True or False
The biological response is the initial reaction to pressure placed on our bodies. -
ANSWER-False
The biological response is the initial reaction to stress on our body.
True or False
The training effect is our body's response to learned and expected stress. - ANSWER-
True
True or False
