Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"More than one-third of people who’ve survived brain hemorrhage stop taking oral anti-blood-clotting drugs, like aspirin. Normally taken to prevent blood vessel blockage, so-called antiplatelet drugs increase the risk of bleeding in general. So they’re widely believed to increase the risk of brain hemorrhage happening again. But new research suggests that might not be the case. Researchers came to that conclusion following a randomized trial involving more than 500 survivors of brain hemorrhage in the UK. Participants were mostly men over the age of 70; all had a history of diseases that cause blockage of blood flow due to clotting but had stopped taking oral antiplatelet drugs after their brain hemorrhage. Researchers split those patients into two groups: half were encouraged to start antiplatelet drugs, and half were encouraged to stay off these drugs..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

• Explain how the properties of blood qualify it as a connective tissue
• Describe the various functions of blood
• Distinguish among the three major categories of formed elements
• Describe the shape, structure, and contents of an erythrocyte
• Know what hematocrit test determines, and what are the normal lab values
• Describe the differences between agranulocytes and granulocytes
• Visually differentiate each of the leukocytes on a normal blood smear
• Visually identify platelets, describe their function, and explain what coagulation tests are used to determine

Now that we've talked about your blood vessels, we're going to zoom in a little closer and talk about your blood itself. We'll start by outlining the basic components of blood -- including erythrocytes, leukocytes, platelets, and plasma -- as well as the basic process of hemostasis that stops bleeding, and how antigens are responsible for the blood type that you have. By the end of this episode, you should be totally prepared for your next blood drive.

This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).
