Quiz on hematocrit, rbc, wbc

Plasma

• 55% in our body, 92% water in 55%

• Contains proteins

• Helps with pH levels (7.35-7.45)

• Transports rbc, wbc, platelets, hormones, enzymes, nutrients, gasses like O2, Co2, N2

White blood cells and platelets

• between rbc and plasma

• Not many

• Granulocytes (3)

• Agranulocytes (2)

Erythrocytes

• Rbc

• Transports O2 and Co2

• No nucleus so that it can pack oxygen

• Hemoglobin: iron containing proteins

Biconcave

• Shape of the rbc

• Large surface area

• Very flexible

• Change shape when going through capillaries

Leukocytes

• WBC

• Granulocytes (3)

• Agranulocytes (2)

Neutrophils

• 50-70% in wbc

• Light purple

• Dark purple is the nucleus (2-5 lobes)

• Phagocytize (fight bacteria)

Eosinophils

• Darker grains (red/pink)

• 2 lobes in nucleus

• Fight parasites

• Low in concentration: 1-3%

• Help control inflammation and allergic reactions

Basophils

• less than 1%

• Many grains

• Blood thinner

• Prevents blood from clotting (heparin)

• Release histamine

• Promotes inflammation in allergic reactions

Monocytes

• 3-9% in WBC

• Phagocytosis of bacteria

• Rid of dead cells

• Formed in red bone marrow

Lymphocytes

• in lymphatic system

• Important to immunity antibodies

• 35-33% in wbc
