Red blood cells are small in the most common type of anemia (iron deficiency anemia, which leads to a condition called microcytic hypochromic anemia), but they are not small in all types of anemia. For example, a deficiency in vitamin B12 or folic acid leads to a type of anemia called megaloblastic anemia, a form of macrocytic anemia, so named because of the characteristic large red blood cells.
Blood cells need to be small to efficiently transport oxygen and other nutrients throughout the body. Their small size allows them to navigate the narrowest blood vessels and deliver essential molecules to every part of the body. Additionally, their shape increases surface area for gas exchange and nutrient absorption.
They have to flow through capillaries (the smallest of your blood vesicles).
Red blood cells are actually larger in diameter than your capillaries, and get through by folding ... which is why a disease such as sickle-cell anemia can be fatal, since the cells become stiff.
Note that some white blood cells are larger than red blood cells, but their shape is amorphous.
in the Philippines, when your blood cell distribution is low you have a sickness called "dengue" (deng-ge) which has had several outbreaks in the Philippines. it is a disease that is received when bit by a mosquito. sometimes this disease can kill especially children. so it is advised to be careful.
so that they can fit through blood vessels
blood cells are small and red
Microvessels, such as capillaries, are so small that blood cells must pass through them in single file. This allows for efficient exchange of oxygen and nutrients between blood and tissues. The small size of these vessels also facilitates the removal of waste products from tissues.
Red blood cells are the most numerous in the blood. They are much smaller than any of the other cells. An adult has about 25 trillion red blood cells, which is about a quarter of the total number of cells in the human body.The red blood cells carry oxygen throughout the body and help carry away carbon dioxide.Red blood cells are also called erythrocytes.White blood cells are not the most numerous cells in the blood.Red blood cells are the most numerous cells in the blood and in the body. They are very small but numerically they comprise roughly one quarter of the cells in the human body.Read more: Are_white_blood_cell_the_most_numerous_cells_in_the_blood
The fluid that leaves blood cells is plasma, which is a yellowish component of blood that contains water, electrolytes, hormones, and proteins. The small particles it contains are platelets, which help in blood clotting, and white blood cells, which are part of the immune system and help fight infections.

Capillaries
So that they can flow to different parts of your body quickly
blood cells are small and red
well you dont want your blood cells to big or to small the red blood cells are what keeps your blood flowing the correct way so yes red blood cells are life threatening.
Because they Are so small they can't get out.
Red blood cells are too small to contain blood vessels. They are cells and they travel in blood vessels.
The blood vessels you speak of are called capillaries (I think)
Plants do not have blood so they do not produce blood cells.
No, a Capillary is a small blood vessel that delivers oxygen and other nutrients to cells.
yes it is true because when you body grows, trillions of blood cells are made. But sence cells are so small it does not effect you size very much.
Microvessels, such as capillaries, are so small that blood cells must pass through them in single file. This allows for efficient exchange of oxygen and nutrients between blood and tissues. The small size of these vessels also facilitates the removal of waste products from tissues.
