The human cardiovascular system is made up of the heart, blood vessels and blood supply. These act as one system to supply vital oxygen, nutrients, and hormones to tissues and remove carbon dioxide and metabolic waste products. This system also plays a central role in stabilizing body temperature and pH levels, as well as maintaining homeostasis. In this free online cardiovascular anatomy and physiology course, the learner will explore the structure and functions of the cardiovascular system. The course explains the composition of blood and provides an overview of how blood is used for transport and energy mobilization. It also outlines how the blood responds to haemorrhage and is involved in maintaining the correct body temperature. The course then examines blood vessels, explaining the function and location of arteries, veins and capillaries. Finally, it covers the anatomy of the heart, describing the structure of the chambers of the heart, the cardiac valves and the heart walls. It also describes the pericardium, the NAVL and the fibrous skeleton of the heart. This free online cardiovascular anatomy and physiology course will be of great interest to professionals in the health care sector who would like a greater knowledge and understanding of the human cardiovascular system. Students of medicine and biology who would like to study the structure and function of the heart, blood vessels and blood supply, which make up this very important anatomical system, will also find this course of great help.<br />

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 />

Step into the world of Tissue Engineering, a rapidly expanding field of applied biology aiming to create artificial organs for transplantation, basic research, or drug development.

This sequence provides an overview of the biochemical basis of cellular structure and function; the anabolic and catabolic processes involved in energy utilization; and cellular communication. The hierarchical organization of cellular components are discussed in terms of the structure and function of the four macromolecules: protein, lipid, carbohydrate, and nucleic acids.

Join us for the Sochi 2014 Winter Olympics! Mega-events like the Olympics are complex phenomena that combine decisions about a short-term festival with long-term social impacts. On the surface, the public spectacle is compelling but going inside the games reveals so much more about the event, athletes, and host city. We will explore the many dimensions of mega-events—history, culture, politics, business, law, sports management, health, and economics—and provide the tools and language to interpret and understand the 2014 Winter Olympics. Join us, and fans around the world, for a month of Olympic spectacle.

This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is o

This course covers specialized and somewhat advanced topics in the fields of cellular biology, molecular biology, biochemistry, and genetics. It does not cover organismal biology or taxonomy. The course is carefully planned to provide the background that biology students will need for advanced biology classes. Non-biology majors will also find this course useful as it explains many of the concepts and techniques currently discussed in the popular press. This course is built around six key concepts that provide unifying explanations for how and why structures are formed and processes occur throughout your study of biology. Because it is not possible to cover the breadth of modern molecular biology in one semester, an understanding of these key concepts will provide a basis for extension of your knowledge to biological systems beyond the specifics covered in this course. One of the major goals of the course therefore is for you to not only learn the definitions of the concepts but also learn to recognize when they are operating the process being studied.
