Blood |
CT composed of liquid portion (plasma~55%) and a cellular portion consisting of various types of cells and cell fragments (formed elements ~45%) Chief means of transport within the body |
|
|
Functions of Blood |
transport of gases, nutrients, hormones, heat, and wastes, regulation of pH, body temp, and H2O content of cells, anti-clotting mechanism, and body defenses |
|
|
Composition of blood |
plasma- watery liquid containing dissolved substances Formed Elements- cells and formed elements (99% RBCs and 1% WBCs and Platelets) |
|
|
Buffy Coat |
white blood cells and platelets, in between plasma and RBCs |
|
|
Plasma |
92% H2O and 8% solutes, "internal environment for cells", collected with anti-coagulants in purple tops |
|
|
Composition of Plasma |

|
Agranulocytes |
Monocytes, and lymphocytes |
|
|
Platelets |
Thrombocytes, disc-shaped, no nucleus, parent cell: megakaryocyte, release substances to stimulate clotting and constriction of blood vessels Decreased- problem with production in the bone marrow, or they're being used up due to disease condition Increased- indicate an activated bone marrow, exertion, or excitement |
|
|
