What are the functions of a red blood cell?

Question

Eg. what are the parts of the cell, like, does it have a nucleus, is it a Eukaryote...

I do know that it carries oxygen, but does it have other parts such as mitochondrion? I searched a web where they say the nucleus gets smaller and smaller, but does it have anything else except hemoglobin?

What is the structure and how efficient is it?

Answer 1

WoW that's a long answer.
Look, the RBC is biconcave disc in shape to provide a larger surface area per volume ratio. It contains haemoglobin, each molecule of haemoglobin binds to four molecules of oxygen at high partial pressures of oxygen eg. near the lungs. The RBC has no nucleus to give more room to haemoglobin ( that's why the RBC doesn't divide). As the blood is transported, haemoglobin starts giving up it's oxygen to the cells where the partial pressure of oxygen is low for respiration and metabolism.

The RBC is rlly efficient since it has large surface area per volume ratio ( as it is biconcave in shape ) for faster rate of diffusion.

As soon as the blood reaches the respiring cells and tissues, and gives up it's oxygen, carbon dioxide binds to the haemoglobin ( this is NOT carboxyhamoglobin. Carboxy haemoglobin is when carbon MONOxide binds wz haemoglobin ) then the blood is transported along the veins that carry deoxygeneted blood, it enters the heart to be pumped to the lungs where it becomes oxygenated then it enters the heart again to be pumped through the aorta reachin all body parts. And the cycle goes on.

Answer 2

The red blood cells are alike all the eucarote cells accept that they do not have nucleus in the cell.However there is a acception. Camels have a nucleus in their RBC's.The RBC's do not have nucleus so that they can use most of the pllace avalable to store hemoglobin. Hemoglobin consists of a iron ion and 4 globin molecules.This hemoglobin helps in transport of oxygen from lungs to other parts of the body.The hemoglobin reacts with oxygen to form oxyhemoglobin which is again broken down to hemoglobin when oxygen is used up. The surface of the RBC's are biconcave so that the cells have more surface area to absorb more oxygen.The Rbc's travel alongwith the WBC's,Platelets and plasma of the blood through the viens and arteries.

Answer 3

The red blood cells are bi-concave in structure. This allows them to store oxygen, which is then transported to various parts of the body for use. Besides the transportation of oxygen, which is one of its main functions, red blood cells also help to control the amount of fluid in and around the blood plasma. For example, when cells surrounding the red blood cells are dehydrated, the red blood cells release fluids through the process of osmosis. Vice versely, when the exterior cells from the red blood cells are over-hydrated, the RBCs take in water, thus expanding into a more round shape. When dehydrated, the RBCs are shriveled in shape. RBCs also help remove carbon dioxiode, a waste product from cells during respiration. Hope that helps :)

Answer 4

Red blood cells are the most common type of blood cell and are the vertebrate body's principal means of delivering oxygen from the lungs or gills to body tissues via the blood.

Red blood cells are also known as RBCs or erythrocytes (from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell"). A schistocyte is a red blood cell undergoing fragmentation, or a fragmented part of a red blood cell.

Answer 5

The principal function is to transport oxygen from the lungs to all other points of the body. Secondary function is to contribute to clotting to limit wound damage.

Answer 6

RBC transport oxygen throughout the body so your body can function at its optimum level....also they are the bulk of the blood volume....platelets are the ones that are used for clotting mechanisms

Answer 7

red blood cell is carrier of oxizen &carbon di oxied through rbc O2 comes in ovewr body & through rbc O2 distribut diffrent part of body & give engry toover body for doing work & colect CO2 from diffrent part of body

Answer 8

carries oxygent and collect carbondioxide
