The red cell membrane contains approximately equal amounts of lipids and proteins. Membrane lipids are either phospholipids or neutral lipids, mostly unesterified cholesterol. Membrane phospholipids are asymmetrically arranged into a lipid bilayer two molecules thick. Choline phospholipids are more abundant in the extracellular surface whereas amino phospholipids are more concentrated on the inner leaflet of the bilayer. Cholesterol is intercalated between the phospholipid molecules. The relative amounts of cholesterol and phospholipids are responsible for the fluid properties of the erythrocyte membrane. Alterations in the membrane cholesterol-phospholipid ratio result in morphologically abnormal erythrocytes with decreased life span. Membrane proteins are also asymmetrically oriented within the lipid bilayer and can be divided into three functional sets: structural, catalytic and receptor proteins. Sprectrin and actin are the two main structural proteins that together form a submembranous cytoskeletal meshwork that is responsible for the viscoelastic properties of the erythrocyte membrane. Band 3, or the anion channel, is a major transmembranous protein involved in the transport of water and anions and is a carrier of the blood-group-I antigen. Glycophorin A, a sialic-acid-rich glycoprotein, is the major contact or receptor membrane polypeptide that also spans the lipid bilayer. The MN blood group determinants and possibly other biologic receptor sites have been localized on the extracellular portion of glycophorin A. At least 35 to 40 enzymes are confined to the membrane and, undoubtedly, play a vital role in the maintenance of normal structure and function of the erythrocyte.
regulates glomerurlar function
It has a hole in it is a rounded shape.
Are you seriously asking that now!?!
It is the basic building block of life
I really dont know i want to know too
regulates glomerurlar function
Cell structure determines cell function
The structure of a bone cell will directly relate to its function. For instance, in the lamellae, there is collagen which will provide the tensile strength to the bones.

Hey Cyle Allen
It is the basic building block of life
The structure and function relate because what the structure is made of infuences what the organ's function is. An example is that the heart is made of strong muscle cells. Therefore, it is fit to do the job of pumping blood around the body.

They are long so they can stretch throughout the body.
Erythrocytes (red blood cells) carry oxygen to other cells..
the back bone is stright, therefore, is grows to keep you growing stright
