Cornell Notes Topic/Title: Blood Components
Blood The only fluid tissue in the human body Classified as a connective tissue
Blood Figure 10.1
Components of Blood PLASMA (55%) WHITE BLOOD CELLS & PLATELETS (>1%) RED BLOOD CELLS (45%)
Components of Blood FORMED ELEMENTS (Red & White Blood Cells and Platelets)
Blood Plasma ~ 90% water Liquid part of blood – Nutrients – Hormones – Proteins
Formed Elements Erythrocytes = red blood cells Leukocytes = white blood cells Platelets = clotting cells
Photomicrograph of a Blood Smear Figure 10.2
Erythrocytes (Red Blood Cells) Main function = carry oxygen Hematocrit = percentage of red blood cells in our body
Anemia Someone is anemic if they have: – A lower than normal amount of red blood cells or – Not enough hemoglobin Sickle-cell anemia – Common in African Americans – Sharp and spiky RBC low oxygen Above: Normal RBC Below: Sickled RBC
Control of Erythrocyte Production Figure 10.5
White blood cells and platelets: Make up less than 1% of the formed elements White blood cells (leukocytes) = fight infections Platelets = involved with blood clotting and wound repair
