Transcript of Red blood cells

Red Blood Cells
Cell organelles
In the Red blood cell there is not any Lysosomes, Mitochondrian, Nucleus, Ribosomes, Vacuoles, Plastids, Flagellum, Cilia, Golgi Apparatus, Rough Endoplasmic Reticulum, and Smooth Endoplasmic Reticulum.There isn't any because even though these are in animal cells like the Red blood cell, the RBC doesn't need these things in order to survive and be a proper blood cell. The RBC does not need these organelles because the Red blood cells purposely lose their Nucleus and other organelles so they can carry more Hemoglobin organelles and they do not need to use any oxygen. It also does not need Chloroplast, and Cell Wall because they are both only in plant cells and the certain RBC we are talking about is an animal cell so it cannot possibly have these organelles.
Rbc diseases
RBCS have many diseases, most of all diseases are related to Anemia. Anemia happens when you have any other disease that shortens RBC lifespan in the circulation. You can also inherit it and people call this Sickle Cell Anemia because of its abnormal Red blood cells.They're abnormal because the Hemoglobin is not normal which causes the whole cell to be abnormal. Sickled cells are removed much more quickly than normal RBCS and eventually leads to Chronic Anemia because the bone marrow cannot keep up with the RBC destruction. Pennicious Anemia is when the immune system mistakenly kills the cells that cause intrinsic factor which causes a loss of vitamin B12 which is needed for RBC production. There is also Aplustic Anemia which is not as common where the bone marrow fails to produce the normal amount of blood cells. The rarest Anemia is Fanconi Anemia which is a genetic condition that causes failure of bone marrow. It has a lot of RBCS, White blood cells, and Platelets which the body ends up in low levels because it can't take how much there is.These are just some of the many RBC diseases that are out there in this world.
What are Red blood cells known for
Red blood cells are also known for many things. One of their short forms is RBC. This stands for Red blood cells. Also they can be known as Erythrocytes, Red cells, Erythroid cells, Red count, Erythrocyte count and Red blood corpuscles.
Extra facts
-Red blood cells perform the most important duty in the body because 1 drop of blood has millions of RBC that are constantly traveling through the body by delivering oxygen and removing waste.
-There are many blood cells. About a quarter of the humans cells are Red blood cells.
-The mature RBCS are oval shaped and flexible hollow disks.
-Your bones constantly keep producing new blood cells which refreshes your supply of blood cells.
-The RBC is very different from any other animal cells because it is not born with a Nucleus. Without the Nucleus it dies because it cannot reproduce itself. This means the Red blood cells eventually die.
-Their most common life cycle is about 120 days or 4 months.
- Red blood cells have a average diameter of about 8 micron.
-Overall no one can survive without blood cells.
The Red blood cell in fact does use the Plasma membrane, Hemoglobin, and the Cytoplasm. The Plasma membrane is exactly the same as the Cell membrane. It is the outer most covering of the cell. The Plasma membrane functions as a barrier, though they readily pass ions, nutrients, and information between the Cytoplasm and the extracellular environment. Hemoglobin in the RBC contains an element of iron and it makes it perfect for transporting oxygen and carbon-dioxide inside the RBC. Basically as blood passes through the body tissue the hemoglobin releases oxygen and the empty Hemoglobin molecules bond with the tissue is carbon-dioxide or other waste gases and transport it away.The Cytoplasm in the Red blood cell is responsible for imparting a vicious nature in the RBC. The Cytoplasm also continues to make Hemoglobin even without a Nucleus. I estimate that there is only 1 Plasma membrane because it is the outer edge of where the cell ends and it serves as a barrier. Plus there cannot be 2 barriers in the Plasma membrane because it would not be an outer edge. I believe there are many Hemoglobin organelles because it is a very super important job. I think this because Hemoglobin is responsible for taking out carbon-dioxide wastes which we keep constantly breathing out so the Hemoglobin is constantly busy taking out the wastes. Also it is responsible for transporting oxygen which we need to live because obviously if we did not have it we would die. Also other organelles like the Nucleus purposely lose their spot in the RBC so that there is more space for the Hemoglobin. I also estimate there is one Cytoplasm organelle because based on what we learned in class we learned that Cytoplasm is a gel like substance and therefore if it was many or some it would of said substances.
