Taking a cellular census. Neutrophils are a type of white blood cell (WBC) in the human body that play a role in the immune system. Information about blood: A person of average size has 5L of blood. Blood contains ~1% WBC’s and ~45% red blood cells (RBC’s) by volume. WBC’s consist of ~60% neutrophils. The density of blood is 1060 kg/m3 and the density of plasma (blood without any cells) is 1025 kg/m3. How many neutrophils are in a typical human, given that the diameter of a neutrophil is 12mm? What is the total mass of neutrophils in a typical human?

Taking a cellular census. Neutrophils are a type of white blood cell (WBC) in the human body that play a role in the immune system. Information about blood: A person of average size has 5L of blood. Blood contains ~1% WBC’s and ~45% red blood cells (RBC’s) by volume. WBC’s consist of ~60% neutrophils. The density of blood is 1060 kg/m³ and the density of plasma (blood without any cells) is 1025 kg/m³.
1. How many neutrophils are in a typical human, given that the diameter of a neutrophil is 12mm?
2. What is the total mass of neutrophils in a typical human?

Expert Solution

Step 1

In human vertebrate Blood is made mostly of plasma, but 3 main types of blood cells circulate with the plasma:1. RBC, 2. WBC, 3. Blood platelets.

Platelets help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken. ...

Red blood cells carry oxygen.

White blood cells ward off infection.

In WBC the neutrophils are a type of white blood cell. They make up the biggest number of all kinds of white blood cells. They kill and digest bacteria and fungi to help your body fight infections and heal wounds.
