Human biology: a body in balance

This module explores human biology, focusing on the science underpinning the structure and function of organ systems. It introduces knowledge of anatomy and physiology, biochemistry, epidemiology, histology, pathology, and science-related mathematics. Throughout the module, you’ll study interactions between the individual and the environment, plus the mechanisms that maintain internal conditions. You’ll also examine how internal and external factors affect the body’s optimal functioning, resulting in disease. In addition to acquiring scientific knowledge, you’ll develop scientific skills, including communication, data interpretation and handling, plus practical and investigative skills.

Modules count towards OU qualifications

OU qualifications are modular in structure; the credits from this undergraduate module could count towards a certificate of higher education, a diploma of higher education, foundation degree or honours degree.

Credits

Credits

  • Credits measure the student workload required for the successful completion of a module or qualification.
  • One credit represents about 10 hours of study over the duration of the course.
  • You are awarded credits after you have successfully completed a module.
  • For example, if you study a 60-credit module and successfully pass it, you will be awarded 60 credits.

Study level

Across the UK, there are two parallel frameworks for higher education qualifications, the Framework for Higher Education Qualifications in England, Northern Ireland and Wales (FHEQ) and the Scottish Credit and Qualifications Framework (SCQF). These define a hierarchy of levels and describe the achievement expected at each level. The information provided shows how OU module levels correspond to these frameworks.

What you will study

SK190 bridges introductory OU level 1 modules and higher-level study. It develops the core subject knowledge and study skills needed for higher education and distance learning within scientific and related disciplines.

The module comprises ten topics:

Topic 1
This topic introduces the building blocks of the human body, exploring the molecular level up to the organ systems. You’ll learn the importance of homeostasis (balance) in physiological processes and participate in collaborative activities that begin developing your communication and investigative skills.

Topic 2
You’ll learn basic genetics and cell biology by looking at diseases caused by gene mutations and how the environment can affect them, human development and diversity. Additionally, you’ll develop data-handling skills and basic numeracy by investigating eye colour distribution.

Topic 3
This topic introduces the structure and function of the nervous system, including the different regions and functions of the brain. You’ll explore how the nervous system controls movement via the musculoskeletal system and how human senses relay information about the internal and external environment to the brain.

Topic 4
This topic explores the role of hormones. You’ll learn about the hormonal control of sleep, growth, metabolism and digestion, and health consequences when hormonal balance is lost. You’ll also develop a greater understanding of scientific communication using graphs throughout this topic.

Topic 5
This topic covers digestion, nutrition and some of the basic biochemistry underpinning energy production in the body. You’ll also learn about recent scientific advances in the role of the gut microbiome and the gut-brain axis in health and disease. This topic also starts to develop your presentation skills.

Topic 6
This topic develops your understanding of microbiology as you learn about the major pathogens and how two immune system branches fight infection. You’ll also explore how knowledge of the immune system and previous vaccine design led to the rapid development of the COVID-19 vaccines. This topic also further develops your numeracy and communication skills.

Topic 7
You’ll learn about the anatomical structure and physiological function of cardiac and respiratory systems and how these two organ systems work in harmony. This topic also includes a live labcast, where you’ll help design an experiment in real time.

Topic 8
As you learn about the kidney and its role in regulating several important physiological processes, you’ll further develop your understanding of cell biology and biochemistry. You’ll learn about kidney diseases and the widespread impact throughout the body if the kidneys function sub-optimally.

Topic 9
You’ll study the structure and function of female and male reproductive systems. You’ll learn about hormonal control of the reproductive systems at different life stages, including during ageing, such as perimenopause. In addition, you’ll learn about changes that occur during pregnancy and the post-natal period. You’ll also briefly examine how contraceptives can prevent pregnancy, the principal causes of infertility, and fertility-enhancing techniques.

Topic 10
Finally, in Topic 10, you’ll explore the causes and consequences of acute and chronic stress. You’ll then consider the impact of acute and chronic stress on all of the body systems studied across the previous topics.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Assessment

The assessment details for this module can be found in the facts box.

Additional Costs

Study costs

There may be extra costs on top of the tuition fee, such as set books, a computer and internet access.

Ways to pay for this module

Open University Student Budget Account

快猫视频 Student Budget Accounts Ltd (OUSBA) offers a convenient &/courses/modules/sk190/39;pay as you go&/courses/modules/sk190/39; option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that 快猫视频 works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

You pay the OU through OUSBA in one of the following ways:

  • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
  • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

Joint loan applications

If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
