The human body cannot generate energy itself and so must obtain it from external sources. Energy from the sun is captured by plants, which in turn are eaten by animals. We humans use these plants and animals as food sources but, in order to obtain the energy we require from them, our food must be broken down into smaller molecules that the body can process. This is accomplished by a complex series of organs known as the digestive system. This free online human physiology course provides a clear introduction to the human digestive system. In this course you will learn how energy is obtained from food and be introduced to the different food types and vitamins. The course looks at the stages involved in ingestion and swallowing, describing how the stomach is designed for food storage and the initial processing of food. How the small and large intestines are structured to facilitate the digestion and absorption of nutrients is also examined. The course also provides an overview of the elimination of the waste products of digestion from the body. It outlines the special roles played by the liver and pancreas in the secretion of digestive enzymes. The mechanisms used by the digestive system to protect the body from infection are covered. This includes looking at the tonsils and other lymphoid tissue in the small and large intestine and explaining how the mammary gland protects the breastfeeding baby from infection. This free online human physiology course will be of great interest to healthcare professionals who would like a greater understanding of the human digestive system and its importance in human physiology, and to students of biology, medicine and nursing who would like to gain a greater knowledge and understanding of the structure and function of the human digestive system. <br />

<p>This free online anatomy course will be of great interest to healthcare professionals who would like to obtain a greater knowledge and understanding of the human nervous system, and to anyone who would like to know more about the structure and function of the central and peripheral nervous systems. </p><br /> <p>The human nervous system is made up of two main parts - the central nervous system and the peripheral nervous system. The central nervous system is made up of the brain and spinal cord, while the peripheral nervous system consists of the nerves that extend to all the other organs in the body. The autonomic nervous system is part of the peripheral nervous system and comprises the sympathetic and parasympathetic nervous systems. </p><br /> <p>In an Introduction To The Human Nervous System you will learn about the structure and function of the central nervous system and the peripheral nervous system; the structure and function of the brain and spinal cord, and how these control and coordinate the sensory inputs and movements of the body. </p><br /> <p>The course also examines the peripheral nervous system and, in particular, the sympathetic and parasympathetic components of the autonomic nervous system. Nerve impulses and synaptic transmission are also explained in detail. </p>

The respiratory system plays a vital role in the inhalation and exhalation of respiratory gases in the human body.

For teachers and trainers to fulfil their instructional role most effectively, their teaching methods must be grounded in educational learning theory. Understanding the learning process is a key element of educational learning theory and provides a framework for teachers and trainers to plan, create and deliver effective lessons, and assess each student's learning. In this free online education course, you will be introduced to the learning process. The course begins by differentiating between teaching and learning, and by describing teachers’ and trainers’ perspectives on learning. The course provides details about two major learning theories: behaviourism and constructivism. Within the section on Behaviourism, operant conditioning and its implications for teaching are examined in detail.
