Blood
• The only fluid tissue in the human body• Classified as a connective tissue

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)
![Page 18: Tuesday, Feb 1, 2011 Objective : Compare Blood Components BR:How are you going to make sure you are successful this semester?](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f0a5503460f94c1e5d7/html5/thumbnails/18.jpg)
Blood Plasma
• ~ 90% water• Liquid part of blood–Nutrients–Hormones–Proteins
![Page 19: Tuesday, Feb 1, 2011 Objective : Compare Blood Components BR:How are you going to make sure you are successful this semester?](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f0a5503460f94c1e5d7/html5/thumbnails/19.jpg)
Formed Elements
• Erythrocytes = red blood cells• Leukocytes = white blood cells• Platelets = clotting cells
![Page 20: Tuesday, Feb 1, 2011 Objective : Compare Blood Components BR:How are you going to make sure you are successful this semester?](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f0a5503460f94c1e5d7/html5/thumbnails/20.jpg)

Erythrocytes (Red Blood Cells)
• Main function = carry oxygen
• Hematocrit = percentage of red blood cells in our body
![Page 22: Tuesday, Feb 1, 2011 Objective : Compare Blood Components BR:How are you going to make sure you are successful this semester?](https://reader036.fdocuments.us/reader036/viewer/2022062720/56649f0a5503460f94c1e5d7/html5/thumbnails/22.jpg)
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

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
