Although the information on this page is based around the anatomy of the canine hindlimb, it is essentially the anatomy of the arteries in domestic species. Any major differences will be discussed on their respective pages

Students will make a proportional model of blood out of red gelatin, a plastic bag, and rice. They will learn about the different components that make up blood and will investigate what happens when the arteries and veins experience buildup from cholesterol. They will then work in pairs to brainstorm ways to clean our clogged arteries.

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:

"Giant cell arteritis, or G-C-A, is a disease of the blood vessels, especially those on the side of the head. In G-C-A, inflammation can decrease blood flow, causing headaches and other symptoms, including blurry vision, which sometimes even leads to permanent blindness. The disease, which affects people over 50, is treated immediately with high doses of glucocorticoids, such as prednisone, to lessen inflammation and reduce the risk of vision loss. But patients often need to stay on these powerful drugs for years, and doctors don’t have good information about how well this strategy works. Now, researchers from around the world have completed the first large randomized clinical trial of a newer drug, tocilizumab, or T-C-Z, in combination with long-term prednisone tapers in patients with G-C-A. The results show that disease flares are common, even when patients are taking prednisone, although adding T-C-Z reduces that risk. In the trial, researchers evaluated four sets of patients..."

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).

This lesson contains background about the blood vascular system and the heart. Also, the different sizes of capillaries, veins, and arteries, and how they affect blood flow through the system. We will then proceed to talk about the heart's function in the blood vascular system. This will lead into a discussion of heart valves, how they work and what might cause them to fail. Then we will discuss prosthetic heart valves.
