Components of
Blood
What are the
parts of blood?
1. Plasma– Clear, yellow colored
liquid
– Makes up 55%
– Contains water (~90%)
and solutes (~10%)
-Amino acids, proteins,
carbs, sugars, ions,
electrolytes, and wastes,
hormones
Plasma (cont.)
• ~45% remainder is
Hematocrit /Blood cells
• Total blood volume
-adult males= 5-6 Liters
-adult females= 4-5 Liters
-American Red Cross
Donations
-Restrictions?
-Hematopoesis
Hem=?
Poesis=?
Why the discrepancy?
2. Erythrocytes– AKA-red blood cells
– Biconcave cellslarger surface area
– Contain hemoglobin
– Lack a nucleus
– Mid-sized
– Most numerous cell
in the blood
– Fxn-transport
Oxygen and Carbon
Dioxide
3. Leukocytes
(see pg. 658 in Marieb)
– AKA-white blood cells
– All Larger than RBCs
– Least numerous cells in the blood
– Contains nucleus
– Fxn: fight disease
3. Leukocytes
– Broken into two groups1. Granulocytes- cells which have a grainy
cytoplasm
2.Agranulocytes- cell which do not have a
grainy cytoplasm
There are 5 Types of WBCs:
Granulocytes1-Neutrophils-use phagocytosis (contain
many lysosomes) on Bacteria
2-Eosinophils-use phagocytosis to engulf
parasitic worms, control inflammation
and allergic rxns, bilobed nucleus
3--Basophils-help with blood clotting
(heparin), histamine-allergic reactions
There are 5 Types of WBCs:
Agranulocytes4-Monocytes-use phagocytosis to engulf
large invading organisms
(macrophages)
5-Lymphocytes-major immunity cell,
produce antibodies
T-lymphocytes- attack infected cells
B-lymphocytes- produce antibodies
4. Thrombocytes– AKA-platelets
– Portions of very large
cells
– ½ size of RBC
– WBC <# < RBC
– FXN-stop blood flow
forming a platelet plug
Summary clip
4. ThrombocytesHemostasis- stopping of
blood flow at a damaged
tissue
Coagulation- formation of a
blood clot, platelets release
chemicals which will assist in
the coagulation, also assisted
by protein fibrinogen]
