Developmental and Physiological Aspects of the Chicken
A laboratory exercise to explore the basic principles of vertebrate heart development, blood flow and electrical circuitry.
Inside the National Archives: The Tuskegee Study (1930s-1972)
Throughout the study, the Public Health Service took photographs for its files. The images survive uncaptioned. Nurse Rivers, who was held in high regard by the participants, is the only person identified in the photographs.
Geopolitics and Imperialism: the British Empire and Halford Mackinder 1890-1940
It was perhaps no coincidence that Halford Mackinder, the most famous exponent of geopolitical theory, wrote his seminal essay in 1904 when British world power seemed on the verge of a secular crisis. This lecture examines how far the insights contained in Mackinder's four major works explain the geopolitical fortunes of the British world system in its age of blood and iron.

Arteries and veins of the zebra fish
Arteries and veins are blood vessels and are part of the circulatory system. Arteries take oxygenated blood away from the heart and veins bring blood back to the heart after it has circulated through the body. The circulatory system distributes oxygen to the body and also moves around nutrients.
Artemia inquiry lab
Artemia blood has blood cells that circulate in an open circulatory system.
Artemia circulation around gut

Arachnids: Tick
One reason why ticks are considered to be arachnids is because they do not have antennae like insects do. Ticks suck blood from animals and are sometimes difficult to remove from the host's skin.
Animal Studies: Leech
One reason why leeches are considered to be annelids is because they have segmented bodies. Leeches suck blood from animals to get food. They release an anesthetic into the animal they are feeding on so that the animal doesn't realize they are feeding on them.
Adult Artemia blood circulation
Artemia adult's blood circulation in the tail and appendages.
4 Summary of video
The search for new medicinal products is one of the major driving forces behind the development and application of new synthetic methods. This unit focuses on a specific case study, which follows the development of a drug for the treatment of high blood pressure. It is a particularly good example of the application of organic chemistry in the pharmaceutical industry, and illustrates the scientific processes that are involved in the development of any new drug.
Cholesterol busting statins and blood pressure
Professor Franco Cappuccio from Warwick Medical School talks about his recent research into the effects of cholesterol busting statins on blood pressure.

RVC 38 - Endothelial Dysfunction and Cardiovascular Disease
Endothelial cells line all the blood vessels in our bodies and disease processes culminating in heart attack and stroke start with problems in these cells. Prof Caroline Wheeler-Jones explains her work examining the importance of particular enzymes and signalling pathways in the function of endothelial cells, and how these go wrong or may be protective against cardiovascular diseases.
1.3.1 Who is affected by cardiovascular diseases?
Your heart beats around 100,000 times every day and, in that time, pumps about 23,000 litres of blood around your body. But what happens when it doesn’t work as well as it should? This unit explains what happens in cardiovascular disease, when the heart’s performance is affected, how the normal function of blood vessels is impaired, and what treatments are available. Whether you are a patient, relative, friend or healthcare professional, you will find the unit interesting.
