A very good morning to one and all present here. Today, I’ll be giving a speech on the topic of ‘blood’.
What is blood? Blood is the bodily fluid that is crucial for human existence without which we humans or any blood-filled organism for that matter, would not survive. It is made up of red blood cells, white blood cells, plasma, and platelets. There are a lot of types of blood, such as O+ve, AB-ve, etc.
Blood has various functions. It transmits oxygen and other vital nutrients to various parts of the body. It fights infections and also helps in the disposal of waste emitted by the body. It also maintains the body temperature and keeps our body warm.
Even a small loss of blood instantly affects the body, starting with a bout of dizziness. Knowing the importance of blood, let us donate blood and help save lives.
