HB134 Semester 2 2008

What to expect

The second unit you are undertaking in Human Biology builds on the knowledge you have acquired so far, then examines how different systems in the body function. The overall purpose of these systems is to maintain homeostasis within the body.   You will examine the cells & tissues (histology) that make up the organs (anatomy) that work together in various organ systems and then see how they function (physiology).

This unit requires that you be active in your learning.   This can take several forms:

• Writing notes in lectures and NOT relying on downloading the lecturers' notes only.
• Taking notes while reading the text
• Answering the questions in the workbook
• Attending tutorials and practicals and taking an active role in these activities

Expect to be challenged. We have set the unit up to encourage active learning and develop self-directed study. While you will be provided with all the information you need, it will not be just handed to you, and you will not always be reminded of your obligations to yourself and others. You will be encouraged to be self-disciplined and to problem-solve, and you will see that, in science, there is not always a right answer or method. You will need to consider the views and beliefs of others as well as your own.

University study is hard work, and if you are studying full-time you will need to treat university as a full-time job. You'll need to be honest with yourself about the quality of your work because you're the one who will benefit from effective study practices.

Advice to be successful

• Attend the practical classes and tutorials and try to do background reading
• Do the focus questions as each topic is covered as this gives you an idea as to the depth of knowledge required to successfully complete the E-tests and exam.
• Do the study questions in the workbook regularly as it gives an indication as to the style of questions asked in the exam
• Once you completed a topic try to integrate the information from the lectures, EOLs, practical and/or tutorial.   Each of these contributes a different aspect of the topic
• Revise continually
• Keep up. Do not get behind.
• Make sure you download the EOL's and read before the practical session
• Attend the lectures
• Study from the beginning
• Be prepared, keep up and work consistently

Overview of HB134

This unit covers the structure and function of the following systems:

• Endocrine system
• This topic involves control of body structures and functions via hormones.   These are substances which can influence another cell in some way, usually to stimulate or inhibit a cellular process.   Endocrine organs, hormones and their modes of action are covered.
• Blood
• Blood is a connective tissue (plasma + formed elements) that TRANSPORTS nutrients and oxygen to all cells in the body.   The different types of formed elements (haemostasis), constituents of plasma and blood parameters are examined.   This also includes blood typing.
• Lymphatics and the Immune system
• The lymphatic system includes all the cells, tissues and organs that defend the body against internal and external pathogens/hazards.   Lymphocytes are the primary cells involved in an immune response and can resist pathogens
• Cardiovascular system
• The circulatory system consists of a pump (the heart) and a means to move the blood to the all cells (blood vessels).   How blood is moved around the heart and the body is examined in this topic.
• Respiratory system
• Respiration involves various stages: Breathing or ventilation and the exchange of gaseous CO 2 and O 2 between atmosphere and cells of body. External respiration is from air to blood (lungs) and internal respiration is from blood to cells (cells) are integrated processes and controlled by centres in the medulla oblongata.   How this happens is examined in this topic.
• Digestive system
• This system is how we obtain the nutrients we need from the environment.   Food that we consume is the raw material that enters our digestive system so that it can be broken down into amino acids, simple sugars and fatty acids which will be subsequently used as building blocks for the proteins, carbohydrates and lipids in the body.   How and where this happens is discussed in this topic.
• Urinary system
• The urinary system is involved in three functions: Excretion of organic waste products (production of urine), elimination of waste products from the body (micturition) and homeostatic regulation of blood plasma volume and ion concentrations.   It also has other functions such as regulating blood pressure and detoxification of poisons.
• Reproductive system
• The reproductive system produces, stores, looks after and transports male and female gametes.   The system consists of gonads, ducts and accessory glands that secrete fluids essential for these functions.   Differences and similarities between male and female systems are examined.

 

TEXTBOOK information

You should have bought (HB133) or be able to access the following textbook:

Marieb, E. and Hoehn, K. 2007

Human Anatomy & Physiology 7th edition, Benjamin Cummings.

This book is highly recommended for those doing future units in Bioscience (Nursing and Physiotherapy)

OR

Tortora G.J. and Derrickson, B. 2006.

Principles of Anatomy and Physiology. 11th edition. New York, John Wiley and Sons.

Lab coats

A White laboratory coat is an essential part of your equipment for studying Human Biology. The Anatomy Act of WA requires that those viewing human cadaver material be suitably dressed, and by this we mean you have to look professional. However, if you require a white laboratory coat for any other unit (e.g. Chemistry) you can use the same coat.

The second hand bookshop sells second hand lab coats and you can also try suppliers of work clothes. You can also check the notice boards for second hand coats for sale.

ASSESSMENT

45% of the unit assessment is progressive. This comprises of

•  Computer based tests based on endocrine, blood, lymphatics & immune system, CVS, respiratory and digestive systems

•  Practical assessments

The remaining 55% of assessment are final practical and written examinations. You should pass the written exam to pass the unit. This is based on questions presented in lectures, EOLs and practicals throughout the semester. This is a combination of multi choice and short written answers.   The practical exam is based on the practicals that you have: anatomy, physiology and histology
