Inquirers Level 3 – After Henry tries to donate blood, he begins to wonder about what happens to blood after it is donated. Investigate and draw a flowchart for the processing of blood that is donated. Think about how blood is checked, classified and stored in this process.
Blood is an essential for the function of the human body. There are people everywhere who are in need of more blood, currently in Australia 1 in every 3 people need blood, and 1 in every 30 people give blood, so the people that are eligible are encouraged to roll up their sleeve and save somebody’s life. For this assignment I will be talking about blood in general, its components, its flow around the body, why it is vital …show more content…
Blood is red because of red blood cells that float in the liquid part of blood (plasma), which is what makes blood a connective tissue. Red blood cells carry oxygen where it is needed and plasma delivers needed nutrients to the cells and removes any unneeded nutrients/waste. The other cells in blood, called white blood cells destroy germs that are trying to get into the blood stream before any damage can be done (infection). There are different blood types, and the different types are based on the red blood cells ' surface. Blood is transported through blood vessels that are all over the body, and is moved by a muscular pump, the heart. This is the basic make up of the cardiovascular system, which carries oxygen, nutrients and removes waste from all cells all over the body. The cardiovascular system also helps to defend the body against infections through the white blood cells. Blood keeps the body’s cells warm (37° C). Plasma is a fluid that is mostly water and it is found in blood. It takes up roughly 55% of the blood. About 1% of blood is white blood cells, and roughly 44% of blood is red cells. In the average human being there are 5 litres of blood. This takes up about 8% of a person’s weight. The volume of blood is increased or decreased by the …show more content…
It also carries wastes like carbon dioxide to the lungs, kidneys, and digestive system so it can leave the body. Without blood, one wouldn’t have the fuel (oxygen-which is delivered through the blood) to perform acts to collect more fuel, so that they can live. Cells and tissues wouldn’t have any fuel to function, so one wouldn’t be able to breathe, eat, and perform acts that are essential for living, and even if they did, none of the nutrients that enter the body through these acts would be doing their job because they wouldn’t be where they need to be, as the blood would transport them and all waste products would be stuck in the body. Your immune system is also located in your blood, and you wouldn’t be able to fight infection or pathogens.
There are four components that make up your blood. These components are plasma, red blood cells, white blood cells, and platelets. Each of these plays a fundamental role in keeping you alive and healthy. In one drop of blood, there are roughly 375,000 white blood cells, 16 million platelets, and 250 million red blood cells. Most blood cells are made in the flat bones of the axial skeleton (cranium, clavicles, scapulae, sternum, ribs, vertebrae, hip bones, and the top of each humerus and
