Acting as biomedical engineers, students design, build, test and redesign prototype heart valves using materials such as waterproof tape, plastic tubing, flexible plastic and foam sheets, clay, wire and pipe cleaners. They test them with flowing water, representing blood moving through the heart. As students creatively practice engineering problem solving, they demonstrate their understanding of how one-way heart valves work.

Olfaction is the sense of smell, which is the ability to perceive and distinguish odours. Most mammals have a good sense of smell, but most birds generally do not. The sense of smell is well-developed in carnivores (predators) and ungulates (prey). Fish also have a fairly well-developed sense of smell. Olfactory and gustatory receptors can combine to contribute to flavour.

"The timing of return to play is one of the most critical decisions made following ACL reconstruction. Returning too early carries the risk of graft failure, while returning too late could cost patients financial and athletic opportunities. Unfortunately, no universal, objective method exists to determine the best time for athletes to resume full activities. But according to a new study reported in The American Journal of Sports Medicine, such methods could be on the horizon, with the help of MRI technology. One promising marker for estimating the best time for athletes to return to play is ACL graft maturation. That’s the process by which a surgical graft makes the transformation from tendon tissue into a substance similar to a normal ACL. The problem is that this transformation is difficult to track over time. Tissue biopsies are currently the gold standard, but are invasive and, in most cases, impractical to perform..."

The oesophageal groove is present in newborn ruminants. It is a channel taking milk from the oesophagus into the abomasum, bypassing the rumen, reticulum and omasum.

The oesophagus (or gullet) is a muscular tube which transports food from the pharynx to the stomach. A bolus of food is passed down the oesophagus by peristalsis. The oesophagus is divided into cervical, thoracic and abdominal sections.

The omasum is the third chamber in the ruminant stomach. It lies within the intrathoracic part of the abdomen so cannot be palpated manually. Instead it is examined by ausculation. The omasum has biphasic contractions which squeeze fluid out of the food before allowing the ingesta to continue into the abomasum. Absorption of volatile fatty acids continues in the omasum.

Oogenesis is the process of producing the female gametes, the Ovum, from the primordial germ cells. The majority of the steps in oogenesis, up to the point of producing primary oocytes, occur pre-natally. Therefore, females are born with all of the Primary Oocytes that they will ever have as primary oocytes do not divide further.

This sample shell is produced by the California Community Colleges CVC-OEI to support faculty in the use of Open Educational Resources and development of courses aligned to the OEI Course Design Rubric. The shell may be used for online, hybrid, &/or face-to-face classes. The shell is available for all faculty, not just those faculty in the CCC system. The team producing this shell includes Helen Graves, Liezl Madrona, Cyrus Helf, Nicole Woolley & Barbara Illowsky. If you are having challenges importing the shell, here are some steps to take. (1) Create an empty shell in your sandbox. (2) Import the Canvas Commons course into your shell. (3) Adapt the content as you wish. (4) If all else fails, contact your college IT person or Canvas administrator.

This zipped folder contains 28 Power Point files that correspond to each of the chapters in the OpenStax Anatomy and Physiology textbook. These are meant to provide a starting point for presentation files related to an Anatomy and Physiology course. The design should be easily modified using the “design” tab in Microsoft Power Point. The end user should be able to quickly choose a template/color scheme that works for them. Additionally, the end user may want to add or remove text from each power point slide. This can easily be accomplished by simply editing the document. Most of the images used in the creation of these Power Points are taken directly from the OpenStax Anatomy and Physiology textbook. Supplemental images pulled from elsewhere include a small textbox with a link to the original work and the CC license terms.

I have been teaching Human Anatomy and Physiology at Central Arziona College (CAC) for 25 years. About 3 years ago, the Dean of Academics expressed concern over the cost of the text and lab book for our 2 semester A&P classes. I volunteered to lead an appointed committee to look into OER for anantomy and physiology. The Openstax textbook quickly became the choice of the committee members. After teaching a pilot class with the Openstax textbook, all CAC 2 semester A&P classes switched over to it. We have been using it for all our A& P classes, both on campus and online, for about 1.5 years. Student feedback has been very positive.

"Heart disease is the leading cause of death worldwide. While people have benefited greatly from advances in drugs and surgery, one glaring problem remains: unlike the cells that make up our other muscles, once heart cells are gone, they simply can’t be regenerated. That is, unless you were just born. Studies show that muscle cells in the hearts of newborn mice, rabbits, and even humans can go on dividing for up to days after birth. And now, in what could be a new world record, scientists have recorded signs of regeneration beyond two weeks after birth in the South American gray short-tailed opossum. Their ability to replicate this feat in mice could point to new ways of healing the hearts of humans with cardiovascular disease. The experiments that led to these results were carried out by Wataru Kimura and colleagues at the RIKEN Center for Biosystems Dynamics Research in Japan..."

The oral cavity is the first section of the alimentary tract that receives food. It provides the digestive functions of prehension, mastication and in salivation and also plays a role in the respiratory system through oral breathing when the nasopharynx is impaired. The oral cavity or mouth, consists of accessory structures (the salivary glands), projecting structures, (the teeth and the tongue) and the walls enclosing the oral cavity.

Osmosis is the passive movement of water across a semi permeable membrane. It occurs in the opposite direction to diffusion of ions. Water moves from a region of low solute concentration and therefore high water concentration to a region of high solute concentration and low water concentration.
