Are the blood cells just suspended in the liquid we call blood?

In summary, blood is composed of both plasma and blood cells, with plasma making up about 55% of the volume. The liquid portion of blood contains water and various chemicals from our food, as well as hormones. The solid part of blood is made up of red and white blood cells, as well as platelets. This composition can vary from person to person and is also affected by factors such as location and climate. Additionally, waste products such as CO2 and organ waste are also present in the plasma.

Is blood completely made up of blood cells, like we are completely made of atoms, or are the blood cells just suspended in the liquid we call blood?

Blood is made up of both plasma about 55% of the volume, the liquid which is mostly water with various chemicals dissolved mostly from our food in it, and some hormones. Red/White blood cells and platelets (involved in sealing wounds) make up the solid part.

Oh ok, thanks for the reply Dagda:)

as in hematocrit - some estimates of plasma go higher

Indeed it varies from place to place, climate to climate and person to person. That said it's probably a good mean.

I forgot to mention those waste products as well such as CO2 and various organ dumping goes into the plasma as well, to be disposed of by the appropriate organs, lungs, liver, kidneys and so on.
 

Related to Are the blood cells just suspended in the liquid we call blood?

1. What are the main components of blood?

The main components of blood are red blood cells, white blood cells, platelets, and plasma. Red blood cells carry oxygen to the body's tissues, white blood cells help fight infections, platelets aid in blood clotting, and plasma is a liquid that carries nutrients, hormones, and proteins throughout the body.

2. Are blood cells suspended in the liquid portion of blood?

Yes, blood cells are suspended in the liquid portion of blood, known as plasma. This allows them to be transported throughout the body and perform their respective functions.

3. How does the body regulate the amount of blood cells in the blood?

The body has a complex system for regulating the amount of blood cells in the blood. This involves the production of new blood cells in the bone marrow, the removal of old or damaged blood cells by the spleen and liver, and the release of hormones that stimulate the production or destruction of blood cells.

4. Can blood cells move freely within the liquid portion of blood?

Yes, blood cells are able to move freely within the liquid portion of blood. However, they may also adhere to the walls of blood vessels or other structures within the body to carry out their functions.

5. What happens to blood cells when blood is donated or transfused?

When blood is donated or transfused, the blood cells are separated from the plasma through a process called centrifugation. The plasma is then used for transfusion, while the blood cells are returned to the donor or recipient. This ensures that the correct amount of blood cells is maintained in the body.
