No as well as normal red blood cells. The problems don't usually start occurring until the cells get to the capillaries. Normal red blood cells are slightly larger than the capillaries, and they are able to squeeze ever so slightly and move through the capillaries.
In sickle cells, the deformities of shape is attributed to a decrease in this ability. They lose flexibility and often are completely unsuitable in size and shape to pass through certain capillaries; leading to many getting stuck.
Certain organs can run into problems with these cells as well such as the spleen, which can cause overwhelming ischemia.
Most of the larger blood vessels will generally not present with problems due to movement of sickle cells.

What is the compared shape of a red blood cell to that of a sickle cell?
The red blood cells have a sickle shape, hence the name. They receive this shape from a protein in normal blood cells that is mutated. They carry less blood and block veins and capillaries easily.
Which functional change of the red blood cells is seen in sickle red blood cells?
Sickle cells have an abnormality in the oxygen-carrying protein hemoglobin. Functionally, sickle cells are more rigid than normal red-blood cells. This can result in them getting "stuck" in capillaries because they don't deform as well as normal red-blood cells to allow them to flow through the capillaries. The sickle cells also break down faster than normal red-blood cells - due to their decreased elasticity they are more prone to "break" when trying to deform to flow through the blood vessels and capliaries, leading to anemia.
Does sickle cell anaemia have white blood cells?
Sickle Cell Anaemia is a genetic disorder that affects the red blood cells. The shape of the cells are changed from being round and flexible to sickle or crescent shaped. These abnormal cells can then clog the blood vessels, causing extreme pain and discomfort. These episodes are known as sickle cell crisis.
How would a slide of sickle cell anemia look like?
sickle cell disease is also a sickle cell anemia is a hereditary problem. It causes type of faulty haemoglobin in red blood cells. Human red blood cells will be circular in shape, so that it can run properly and move flexible in blood vessels but Sickle cell anemia will be in sickle or like crescent moon shape, so that they cant move well in small blood vessels and it blocks the blood vessels. If the blood vessels are blocked it causes low supply of oxygen to body organs and it causes severe pain, infection, jaundice and may also cause strokes. It also leads to death of a person.
What are abnormal crescent shaped BLOOD cell?
Abnormal crescent-shaped blood cells are known as sickle cells, which are characteristic of sickle cell disease. This genetic condition causes red blood cells to become rigid and curved, leading to blockages in blood vessels and reduced oxygen delivery to tissues. Sickle cell disease can result in pain, organ damage, and other serious complications.
Which is a genetic disorder in which abnormal hemoglobinleads to fragile red blood cells and obstructed blood vessels?
Sickle-cell anemia
Why do sickled red blood cells cuase so many problems?
Its not sickled blood cells that cause problems, it's sickle cell anemia. Sickle cell anemia (uh-NEE-me-uh) is the most common form of sickle cell disease (SCD). SCD is a serious disorder in which the body makes sickle-shaped red blood cells. "Sickle-shaped" means that the red blood cells are shaped like a crescent. Normal red blood cells are disc-shaped and look like doughnuts without holes in the center. They move easily through your blood vessels. Red blood cells contain an iron-rich protein called hemoglobin (HEE-muh-glow-bin). This protein carries oxygen from the lungs to the rest of the body. Sickle cells contain abnormal hemoglobin called sickle hemoglobin or hemoglobin S.Sickle hemoglobin causes the cells to develop a sickle, or crescent, shape. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage.
Why is a sickle cell less efficient at carrying oxygen around the body the normal red blood cells?
Sickle cell has a different shape due to a genetic mutation, causing the red blood cells to be rigid and form a sickle shape. This can block blood flow and decrease the cell's ability to carry oxygen efficiently. Normal red blood cells are flexible and can move freely through blood vessels to deliver oxygen.
What cells move easily through blood vessels?
white blood cells
Sickle-shaped red blood cells carry less oxygen than healthy cells. What is another side effect of this disease?
Another side effect of sickle cell disease is the tendency for sickle-shaped red blood cells to get stuck in blood vessels, leading to blockages that can cause pain, organ damage, and even stroke.
Why sickle cells block the capillaries?
The 6 amino acid in the hemoglobin beta chain is different than that of a normal hemoglobin protein. This causes the hemoglobin protein to change shape, and if a protein changes shape it also changes function. These proteins have more hydrophobic areas that link together to form chains. It is these chains that causes the blood cell to become sickle in shape. These blood cells are hard and more sharp on these edges, while normal blood cells appear as if they a soft dougnuts. When normal blood cells travel through blood vessels they sometimes bounce off the vessel walls, this is also true for sickle cells but instead of bouncing off they become inbedded in the vessel wall. over time other sickle cells pile up on the original sickle cell eventually blocking the vessel completely.
Do sickle cells have a nucleus?
"Sickle cells" refers to an abnormal shape (rather like a sickle) of red blood cells. Red blood cells in humans do not have a nucleus.
