Instructors consistently ask for a human biology textbook that helps students develop an understanding of the main themes of biology while placing the material in the context of the human body. Mader's Human Biology was developed to fill this void.
To accomplish the goal of improving scientific literacy, while establishing a foundation of knowledge in human biology and physiology, Human Biology integrates a tested, traditional learning system with modern digital and pedagogical approaches designed to stimulate and engage today’s student.
Multimedia Integration: Michael Windelspecht represents the new generation of digital authors. Through the integration of multimedia resources, such as videos, animations and MP3 files, and in the design of a new series of guided tutorials, Dr Windelspecht has worked to bring Dr. Mader’s texts to the new generation of digital learners. A veteran of the online, hybrid, and traditional teaching environments, Dr. Windelspecht is well versed in the challenges facing today’s students and educators. Dr. Windelspecht guided all aspects of the Connect content accompanying Human Biology.
The authors of the text identified several goals that guided them through the revision of Human Biology, Thirteenth Edition:
- build upon the strengths of the previous editions of the text,
- enhance the learning process by integrating content that appeals to today’s students,
- deploy new pedagogical elements, including multimedia assets, to increase student interaction with the text,
- develop a new series of digital assets designed to engage the modern student and provide assessment of learning outcomes.
productivity, according to the American Heart Association. Family history of heart attack under age 55, male gender, and ethnicity (people of African-American descent are at great risk) are unalterable risk factors for CVD. However, most cases of CVD are preventable (Fig. 5A). Preventable risk factors include ■ ■ ■ ■ ■ ■ Use of tobacco: Nicotine constricts arterioles, increasing blood pressure. As a result, the heart must pump harder to propel blood. Carbon monoxide in smoke decreases the
Trace the pathway of blood to and from the brain in the systemic circuit. (page 103) 13. Describe the process by which nutrients are exchanged for wastes across a capillary, using glucose and carbon dioxide as examples. (pages 104–105) 14. What is the most probable association between high blood pressure and a heart attack? With this association in mind, what type of diet might help prevent a heart attack?

infection cannot be overcome. Inflammatory chemicals may cause collateral damage to the body, in addition to killing the invaders. Should an inflammation persist, anti-inflammatory medications, such as aspirin, ibuprofen, or cortisone, can minimize the effects of various chemical mediators. Protective Proteins The complement system, often simply called complement, is composed of a number of blood plasma proteins designated by the letter C and a number. The complement proteins “complement”
develop into the complete organism. Cell Size A few cells, such as a hen’s egg or a frog’s egg, are large enough to be seen by the naked eye. In comparison, a human egg cell is around 100 μm in size, placing it right at the limit of what can be viewed by our eyes. However, most cells are much smaller. The small size of cells is explained by considering the surface area-to-volume ratio of cells. Nutrients enter a cell—and waste exits a cell—at its surface. Therefore, the greater the amount of
temperature rises above normal, the hypothalamus senses the change and causes blood vessels to dilate and sweat glands to secrete so that temperature returns to normal. Below: When body temperature falls below normal, the hypothalamus senses the change and causes blood vessels to constrict. In addition, shivering may occur to bring temperature back to normal. In this way, the original stimulus is resolved, or corrected. Above-Normal Temperature When the body temperature is above normal, the
