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:

"A recent study published in Acta Neuropathologica Communications has found a potential mechanism for the initiation and development of Parkinson’s disease and it appears red blood cells may be partly to blame. Parkinson’s is a chronic and progressive neurodegenerative disorder commonly associated with tremors, muscle stiffness, and impaired movement. While these symptoms are caused by the deterioration of nerve cells in the brain, the precise cause of the disease is still not fully understood. What is known is that the development of Parkinson’s is associated with the aggregation of toxic forms of a protein named alpha-synuclein (or alpha-syn, for short) in the brain. Recent evidence, however, suggests alpha-syn found in the blood can also be problematic and this has been implicated as a contributor to brain-cell breakdown..."

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

This video shows scanning a Wright's stained blood smear slide with pauses to view leukocytes. The video was taken at 630X under a brightfield microscope. This video is compatible with a laboratory lesson in which students observe, categorize, and count leukocytes. More than 100 leukocytes are viewed in this video. Note, this video does not have narration.Video credit: Emily Fox

Also known as red blood cells (RBCs). Erythrocytes deliver oxygen to, and remove carbon dioxide from tissues. Erythrocytes are derived from the stem cell (CFU-GEMM) and formed in a process known as erythropoiesis.

This text been designed for an undergraduate human anatomy and physiology course at a medium sized public university. This text has been modified from the original OpenStax text to encourage more active reading for an early undergraduate student taking the first semester of a year-long human anatomy and physiology course sequence. This text has been targeted to our student population, consisting primarily of first semester pre-nursing and kinesiology majors at a university with a high proportion of first generation and PELL-eligible students who benefit from lower barriers to entry into the field. Therefore, freely-available and differently presented text can be beneficial to this student population. This version was designed with the intention of distributing it section by section through a learning management system. If this mode of distribution is used, connection to an assessment tool could be utilized. Systems covered include skeletal, muscular, cardiovascular, respiratory, and nervous.

As this text reorganizes and modifies an OpenStax’s Anatomy and Physiology 2e (see related resources link below), chapter numbers and chapter section numbers from the original have been preserved in this document. Material supplemented from other sources is cited within the text.

Course connections: Undergraduate courses aimed towards freshmen or sophomore, including Anatomy and Physiology, Introduction to Anatomy and Physiology, Physiology, Introduction to Physiology, Human Biology or similar with a human focus.
