Workbook on Body Compartments, Cell and Homeostasis for Biosciences in Nursing

Year 1
Biosciences for nursing
Workbook on the
body compartments, cell
and homeostasis.

Biosciences workbook
This workbook aims to further reinforce knowledge and understanding of
students on the systems of the body and to enable them to study at their
own pace. It is also a self- assessment tool for students to identify whether
learning has taken place. It encourages close reading of the lecture notes
and textbook to find the relevant information.
Learning anything new takes a lot of effort. Learning is an active process;
you need to engage with the work and practice writing the new ‘language’
down in your notebook (or online portfolio). Pay attention to how the words
are spelt for example, it is easy to confuse atria and arterial. Eventually this
language will become your own language. Reading is a very passive activity,
reading alone is not a good way to learn, you need to engage fully by
questioning everything you read. This workbook is designed to help you with
this, however, just completing the workbook is not enough, if this subject is
new to you will have to go over it many times.
Although many of the answers can be found in the lecture notes, not all can
be found here. Please use your textbook to read around the subject to
extend your knowledge and understanding. However, there is often much
more in textbooks than you need to know. In order to help you focus on what
you need to know the learning outcomes for each session are given to you.
In this workbook there is a separate section for each lecture. Please
complete and submit (workbook submission portal) the relevant section
following your lectures in preparation for the ‘live’ quiz. If you leave the work
for a few weeks, you will find it very difficult to catch up.
Read you lecture notes and textbook prior to completing each section. Can
you answer the questions without looking back at your notes? Sometimes
the same question is repeated in a different way. This is deliberate as
repetition helps us to remember.
Good luck!

Body compartments and a cell
1. Define the following terms:
Cell: Cell is the smallest unit in living organisms and tissues in the body. A cell has
capability to live on its own and it is considered as smallest structural, biological
and fundamental unit of life. Cells are majorly responsible for all processes and are
also known as building blocks of life.
Organ: Organ is a differentiated structure (such as kidney, heart, lung, liver, etc.)
composed of cells and tissues and responsible to perform a particular function in
an organism. These body parts tend to function in coordination
System: System is a group of interrelated elements which act on the basis of
already set rules in order to unified whole. A system is always described by its
boundaries, purpose and structure that expressed in its function. It keeps
surrounded and influenced by its environment.
2. Identify the location of the following organs in the body cavities:
Organ Cavity
Spinal cord Dorsal Body Cavity
Lungs Chest Cavity
Kidneys Abdominal Cavity
Heart Chest Cavity
Liver Abdominal Cavity
Stomach Abdominal Cavity
Spleen Upper Left Abdominal Cavity
Brain Cranial Cavity
Gall bladder Upper Right Abdominal Cavity
Pancreas Abdominal Cavity
Bladder Pelvis
Urethra Abdominopelvic Cavity
3.What structure separates the thoracic and abdominal cavity
The diaphragm is a thin dome-shaped muscular structure which separates the
thoracic cavity from abdominal cavity. The thoracic cavity consists lungs and heart
while abdominal region of body includes intestines, liver, stomach, etc. The
diaphragm involved in respiration, inhalation and exhalation. The structure is
shaped like a parachute and contract continually and rhythmically as well as
involuntarily. During inhalation, contraction and flattening of diaphragm, enlarge
chest cavity due to which a vacuum creates and air pulls into the lungs. While
during relaxation, the relaxation and gaining of dome-structure of diaphragm,
enclose chest cavity which force out air out of the lungs.
