Red blood cells or erythrocytes are small biconcave blood cells that lack a nucleus when they are mature and carry oxygen throughout the body. They lack the nucleus and most organelles in order to maximize room for hemoglobin. The cells are active for about 100â??120 days. New cells are made in the bone marrow.

What Carries oxygen-rich blood around your body?
The simplest answer is "arteries," which generally carry oxygen-rich blood from the heart to the body, but the pulmonary veins also carry oxygen-rich blood. The lungs have oxygen that gives oxygen to the cells. Our body is a closed system so the blood never leaves the body system unless we are cut. After the blood has used up all of the oxygen it has the blood is recirculated through the heart and lungs once more! Thus this process goes on and on! An ARTERY carries oxygen rich or oxygenated blood from the heart to the body cells to give oxygen to them. I remember this by: Artery Away Arteries carry oxygen rich blood from the lungs to other parts of the body. Veins return oxygen poor blood to the heart where it gets recirculated through the lungs and then throughout the body again. The arteries.
Does plasma carry oxygen?
When oxygen enters the bloodstream through the lungs it generally binds to red blood cells (more specifically the hemoglobin within red blood cells), which are carried along within the plasma. While some unbound oxygen may become diffused inside the plasma itself it is not the primary or intended mean of oxygen transport throughout the body. In short, plasma doesn't carry oxygen, but instead carries the cells that carry oxygen.
What is the oxygen atom of a water molecule?
Oxygen atoms in water molecules are the same as oxygen atoms in any other molecules; the definition of an oxygen atom is that it is an atom which has eight protons in its nucleus. Normally it has eight neutrons and eight electrons as well, but that can vary. It is only the eight protons which define it as oxygen.
Describe how to find the atomic number for the element oxygen?
Okay, here is a simple way to find the atomic number, Count the protons or if you want a more techical way. Take the total mass of the nucleus minus the mass of all the neutrons then divide the rest of the mass by the mass of one proton.
How do astronauts breathe in space?
Astronauts carry air tanks with them that contain mostly pressurized oxygen and nitrogen. Their suits circulate the air to their helmets and throughout their entire suit so that they can breathe.They breath threw oxygen tanks tied to their backs. If an astronaut was to take it off and try to breath, he/she would start to choke and die.
What will some stem cells become if they mature into erythrocytes?
If stem cells mature into erythrocytes (red blood cells), they will become specialized for oxygen transport in the body. Erythrocytes are responsible for carrying oxygen from the lungs to the rest of the tissues and organs, as well as removing carbon dioxide waste. They have a unique biconcave shape and lack a nucleus to maximize their capacity for oxygen-carrying.
How do red blood cells get the biconcave shape?
They have no nucleus, so they sink in in the area where the nucleus should be. Oxygen binds to the surface of the cell, so the increased amount of surface area due to the biconcave shape gives it more space to carry oxygen.
How is the function and structure of a red blood cell related?
A red blood cell has no nucleus and a biconcave shape. This structure allows it to carry oxygen more efficiently.
What does a red blood cell not have that other animal cells have?
Well, All i know is that.. Red blood cells are elastic and do not have any nucleus, so as to allow more hemoglobin to be packed in it. This is also to allow them to squeeze through the capillaries to supply tissue with oxygen. Red blood cells also have a biconcave shape, to increase the surface area to volume ratio of the cell. And also, this also allows oxygen to diffuse in and out of the cell faster.
What other characteristic does a red blood cell have that enables it to perform its function optimally?
-Has a large biconcave surface area to carry more oxygen -Contains haemoglobin, so when reacted with oxygen turned into oxy-haemoglobin for transportation -Has no nucleus to carry more oxygen
Did red blood cells ever have nucleus?
They did have a nucleus . When they are formed in the bone-marrow, they contain a nucleus, but when the become mature it is replaced by haemoglobin in order to carry more oxygen. By- Pranjal Prasoon
What structure is missing from the red blood cell that is found in most other cells?
Red blood cells that lose their nucleus also lose their mitochondria. It is an adaptation of the red blood cells in order to carry more oxygen and transport the oxygen to the different parts of the body.
Why dont red blood cells contain a Nucleus?
The loss of the nucleus is all part of the red blood cell's adaptations for its function of carrying oxygen around the body. Each cell is packed with a protein called hemoglobin, which attracts oxygen very strongly when blood flows through the lungs, so can carry as much oxygen as possible. Its other adaptation to its function is that it has a biconcave shape - this enables it to have a large surface area for picking up oxygen in the first place. During their maturation in mammals, a red blood cells loses its nucleus, mitochondria and endoplasmic reticulum, which makes them inactive metabolically.
Notes on red blood cell?
Biconcave disk containg haemoglobin for the transport of oxygen. These cells have no nucleus or mitochondrion so as to ensure they do not use up the oxygen they carry instad they generate all their ATP through gycolysis. RBCs are mostly produced in the bone marrow.
What appear as biconcave disks with edges?
Red blood cells have a circular biconcave shape to increase surface area to volume ratio for faster absorption of oxygen in the bloodstream.
When a mature red blood cell loses its nucleus it loses its ability to do what?
Red blood cells do not have a nucleus in order for them to be able to carry more oxygen. The only thing they do is transport oxygen, therefore they do not need a nucleus. They do not lose any ability because their only purpose is oxygen transport.
Tiny biconcave disks that carry oxygen is called?
red blood cells or erythrocytes
