What appear as biconcave disks with edges that are thicker than the center of the cell looking somewhat doughnut shaped. They do not have a nucleus and are simple in structure?

These cells are red blood cells, also known as erythrocytes. Their biconcave shape allows for increased surface area for oxygen and carbon dioxide exchange. Red blood cells lack a nucleus to make more room for hemoglobin, the protein responsible for carrying oxygen.


Why are red blood cells shaped and desined in the way they are?

I'm not an expert at all, but the biconcave disc shape is, as far as I know, to increase surface area available for diffusion. Since the RBCs transport oxygen, the greater the surface area, the faster the oxygen can diffuse in and out of the blood. Hope that helps!


What was the very first virus written in 1981 called?

The first computer virus, written in 1981, was called the Elk Cloner. It infected Apple II computers through infected floppy disks and displayed a short poem to the user.


Thylakoid disks are?

Thylakoid disks are structures found within the chloroplasts of photosynthetic organisms. They contain the pigments and protein complexes responsible for capturing light energy and converting it into chemical energy during the light reactions of photosynthesis. The interconnected thylakoid disks form the grana, where the photosynthetic reactions take place.


Is a specialized connective tissue located in the intervertebral disks to absorb shock?

Yes, the specialized connective tissue in intervertebral disks responsible for absorbing shock is called the nucleus pulposus. It is a gel-like substance located in the center of the disk, surrounded by fibrous tissue known as the annulus fibrosus. The nucleus pulposus helps the spine to maintain flexibility and absorb impact during movement.

Tiny biconcave disks that carry oxygen is called?

The tiny biconcave disks that carry oxygen are called red blood cells or erythrocytes. These cells transport oxygen from the lungs to the tissues in the body and play a crucial role in maintaining normal body function.


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.


Which cells are shaped like pinched disks?

Red blood cells are typically shaped like pinched disks, also known as biconcave discs. This unique shape allows them to carry oxygen efficiently through the bloodstream.


What shape best describes a red blood cell?

A red blood cell is disc-shaped with a thin center and thicker edges, resembling a biconcave disc. This shape allows for flexibility and more surface area for oxygen exchange.


What is the normal shape of the red blood cells?

Normal blood red cells are biconcave disks, approx. oval.

What shapes would most benefit red blood cells considering that RBCs are responsible for carrying oxygen from the lungs to all the various body tissues?

Overall, mammalian red blood cells are remarkably flexible and deformable so as to squeeze through tiny capillaries, as well as to maximize their apposing surface by assuming a cigar shape (called a stack), where they efficiently release their oxygen load. Red blood cells are deformable, flexible, are able to adhere to other cells, and are able to interface with immune cells. In humans, mature red blood cells are flexible and oval biconcave disks which gives them the ability to get through the tiniest capillaries. The red blood cells of mammals are typically shaped as biconcave disks: flattened and depressed in the center, with a dumbbell-shaped cross section, and a torus-shaped rim on the edge of the disk. This distinctive biconcave shape optimizes the flow properties of blood in the large vessels.


How do use red blood cells in a sentence?

Red blood cells, which look like little disks , carry oxygen from the lungs to all body parts.


How does the structure of the red blood cell relate to its function?

Shape (biconcave disks) - increases surface area, enhancing rate of diffusion of oxygen across their plasma membranesLack nuclei - leaves more space for hemoglobin (the protein that transports oxygen)Lack mitochondria (therefore anaerobic metabolsim) - more efficient as none of the oxygen that the cell is transporting is consumed by the cell(Source: Biology, 8th Edition, Campbell and Reece, Pearson International Edition, pg.912)
