In this animation, we delve into the different functions and components of blood. Blood is a mixture of various cells suspended in a fluid called plasma. Although fundamentally different in both appearance and function, all blood cells originate from a single type of stem cell in the bone marrow. Red blood cells, or erythrocytes, are made up of little sacs of haemoglobin which are designed to carry oxygen. White blood cells, or leukocytes, are part of our immune system and move in and out of blood vessels searching for any signs of infection or cellular abnormalities. Platelets, or thrombocytes, help repair the blood vessel in the event of an injury by helping the blood to clot.

Yasmina Haifi, who works for the Dutch Justice Ministry’s National Cyber Security Centre, made the controversial statement on Twitter, Dutch newspaper De Telegraaf reported.
Referring to IS by their former name, the Islamic State of Iraq and the Levant (Isis), she tweeted: “ISIS has nothing to do with Islam. It’s part of a plan by Zionists who are deliberately trying to blacken Islam’s name.”
Ms Haifi later removed the original message and said: “I realize the political sensitivity in connection with my work. That was not my intention.”
It is now believed that she has been suspended from her position.
