Why is the shape of a red blood cell donut shape?
When a red blood cell matures it pushes out its nucleus. Its internal structures go through a shape change, giving the cell a discoid form, bi-concave, depressed centrally on both sides but not so much that the depressions meet to form a hole.
The technical term for a doughnut shape is 'torus'. A red blood cell is 'toroid' or 'a toroid' or 'toroidal'. Perhaps one could say it was a 'closed torus'.
This shape allows for more surface area to bind oxygen and carbon dioxide during gas exchange. The cells distinct form also makes the cell more flexible so that it can get through the smaller blood vessels.
The red blood cells that transport oxygen in the blood are circular in shape with the center compressed - kind of like a donut, but where the hole would be is a "well" of tissue. It is shaped like this because this shape increases the surface area of the cell and allows it to carry more oxygen. The shape makes it more efficient.
Well, there can either be one answers out of the two answers: 1. They wanted to get eaten by the cops so they disguised them as jelly doughnuts. ---------------------------------------OR------------------------------------------ 2. When a red blood cell matures it pushes out its nucleus. Its internal structures go through a shape change, giving the cell a "doughnut" shape but just flat in the middle, without a hole. This shape allows for more surface area to bind oxygen and…
A red blood cell contains a red pigment known as HAEMOGLOBIN.We know that haemoglobin is a protein.Its structure is quertenary which means its made up of coiled polypeptides.2 beta and 2 alpho.This therefore means the shape of a red blood cell is determined by quertenary structure of its red pigment.
Some people have diseases, such as Sickle Cell Anemia. The disease makes a person's red blood cells in the shape of a sickle, hence the name, "Sickle" Cell Anemia. A normal person's red blood cell shape is round as opposed to the diseased person's red blood cell. It depends on the type of disease the person has. Some are round, some sickle shape, and others raisen-like (drained).
How do you differentiate between red blood cells and yeast cells in stool examination as it really looks similar?
Poikilocytosis is the medical term meaning any disorder of red blood cell morphology (shape). Examples include sickle-cell anemia and spherocytosis, among many others. Normal red blood cells are disk-shaped with two dents, one on each side. A poililocyte is any blood cell that doesn't have that shape.
What is the medical term meaning stained blood smear is examined to determine the shape of individual red blood cells?
