Red+Blood+Cells+-+MK

Red Blood Cells Have you ever been so winded that you couldn't breath? Well the Red Blood Cells are working hard to bring fresh oxygen to your lungs. Red Blood Cells have a very distinct shape so its allowed to do its job. these cells have a certain amount of time before they are put into the bloodstream. Maybe you would think that the Red Blood Cells stay alive forever, although they have a certain amount of time serving for your body. You may think that there is 10, 15 or even 20 Red Blood Cells in your body, how many do you think there are well ill tell you.

=**The job of the Red Blood Cell**=

Red Blood Cells are the most common type of blood cell and the vertebrate organisms principle means of delivering oxygen to the body’s tissue via blood flow.
=How are they shaped?= ==== Red Blood Cells are shaped very much like a flexible disk or some people say a pinched in center or a doughnut, the structure of the cell is the reason it is allowed to bend and flow smoothly in the tight and narrow capillaries. ====

= Are they produced everyday? = P roduction of the Red Blood Cell is controlled by the Erythropoienin, a hormone produced in the Kidney, Red Blood Cells start as immiture cells in the bone marrow and approximitly seven days of maturation, they are released into the blood stream, unlike many cells theswe cells lack a nucleus, they need the space for oxygen, however the lack of the nucleus makes it more flexible.

=What is this life span?=

About every second 2 million Red Blood Cells die, because of the lack of the nucleus they must produce at the same rate as their death.
=Number of Red Blood Cells in your body= ==== In a healthy man there are 25 trillion red cells in his body, about every second 2 million Red Blood Cells die, they must be produced at the same rate. More than 200 billion Red Blood Cells die every day by the spleen, the immune system removed old red blood cells and used it as a reserve of blood incase of a heart attack. ====

Red Blood Cells, as I said earlier, are a very important part of your body and today you learned overall about the cell such as the shape, production, life span and the number of the wonder cells in your body. Hopefully you know more about how these cells work and help your body before you read this!
