Movement and Physiology BSC1005 Exam
(Final) Questions with 100% Verified Answers
UPDATED!!!
Physiology - ANSWER the science of body functions
Homeostasis - ANSWER refers to the maintenance of a constant
internal environment despite external changes, or changes
caused by variation in the biological activity within cells, tissues
and organs.
Three common examples of homeostasis and brief explanations
- ANSWER 1. Running- acute, short-term adjustments in oxygen
(O2) delivery to, and carbon dioxide (CO2) removal from
muscle.
2. Spending time at high altitude- Body produces more oxygen-
carrying red blood cells.

3. Maintenance of blood glucose concentration despite changes
in diet, frequency of eating or drinking, and variations in
glucose use by cells in the body.
Pathophysiology - ANSWER Changes in physiology associated
with disease
Important of understanding both normal physiology and
pathophysiology - ANSWER Understanding disease mechanisms
and physiological responses to disease helps us to better relate
to and assist those affected and to develop a better
understanding of normal physiological processes.
Benefits of biomedical research for individuals - ANSWER It is
improving medical practice for human health and decreasing
death rates for diseases such as cancer
Benefits of biomedical research for families - ANSWER It
reduces disease incidence and severity that may take a physical
and emotional toll on the affected person's family.

Benefits of biomedical research for society - ANSWER Since
poor health increases costs of health care and reduces
productivity at work, research to prevent poor health helps
society as a whole.
What system within the body is blood part of? - ANSWER the
circulatory system - specifically cardiovascular system (pumped
through the heart through blood vessels)
Why can blood be considered a type of connective tissue, even
though it is a fluid? - ANSWER It connects cells throughout our
body as it continuously circulates within our blood vessels.
Major cellular components of blood and their function (3) -
ANSWER 1. red blood cells- transport oxygen and carbon
dioxide
2. white blood cells- components of our immune system that
help fight disease
3. platelets- help clotting to prevent blood loss
Major components of blood plasma (4) - ANSWER 1. Water
2. Electrolytes
, 4|Page
3. Small molecules
4. Blood proteins
What are the general features of the cell? - ANSWER It is
surrounded by a membrane composed of lipids arranged in a
bilayer structure. This cell membrane separates the inside the
cell from the external environment. Inside the cell is the
cytoplasm.
True or False?
Cells are the basic units of life. - ANSWER True
Hematocrit - ANSWER percentage of blood volume occupied by
red blood cells (put simply: the amount of RBC in your blood)
Physiological importance of hematocrit - ANSWER Hematocrit
will increase, which increases red blood cells, when
atmospheric oxygen levels are low. It can also decrease due to
bleeding not easily seen by the eye. Therefore, it helps your
body in low oxygen levels and can be checked by doctors to get
an insight into your health.
