Composition of Blood
| Question | Answer |
|---|---|
| Name the three major functions of blood: | 1)Transportation 2) Protection 3) Regulation |
| Name some materials that blood is responsible for transporting: | nutrients, O2, hormones, ions/electrons, CO2, waste products |
| Name the component of blood responsible for protection against pathogens: | White blood cells |
| Name 2 ways in which blood is responsible for regulation: | 1) Body temperature control 2) blood clotting |
| Whole blood is approximately ____% plasma, <1% ______ _______, and ____% erythrocytes (RBCs) | 55, buffy coat, 45 |
| Another name for leukocytes is: | white blood cells |
| Another name for erythrocytes is: | red blood cells |
| Another name for platelets is: | thrombocytes |
| The most abundant of the "formed elements" of blood is: | red blood cells |
| Plasma is over ______% water. | 90 |
| Plasma is made up of these 3 things: | 1)Water (over 90%) 2)Plasma proteins 3)"other solids" |
| Plasma proteins are produced primarily by the _______. | liver |
| Name the 4 types of plasma proteins: | 1)Albumin 2)Globulin 3)fibrinogen 4)regulatory proteins (enzymes, hormones) |
| Albumins make up ____% of the plasma proteins. | 60 |
| Albumins maintain the _______ _______ of blood. | osmotic pressure |
| A measure of the solid concentration of the blood: | osmotic pressure |
| Nondiffusible (big, bulky) proteins that keep water in the blood by keeping it "salty" (remember, the osmotic principle that WATER FOLLOWS SALT) | Albumins |
| Globulins make uo ___% of the plasma proteins. | 35 |
| This type of plasma protein collectively make up our antibodies (Ab): | Globulins |
| The type of plasma protein that is an inactive precursor to the insoluble protein "net" involved in the clotting process: | Fibrinogen |
| Fibrinogen makes up ____% of the plasma proteins. | 4 |
| The least abundant of the different types of plasma proteins: | The regulatory proteins (hormones, enzymes, and proenzymes), which make up <1% of the plasma proteins. |
| Name the 3 formed elements (cellular components)of blood : | 1)Red blood cells 2) White Blood Cells 3) Platelets |
| The "other solutes" in plasma are: | electrolytes (ions), and organic nutrients (such as: glucose, fatty acids, and amino acids), and organtic waste products. |
| This electrolyte in the plasma is VERY important in the clotting process: | Ca++ (calcium) |
| The ________ ion is important in maintaining blood pH balance and in the respiratory system. | bicarbonate (HCO3) |
| uria, uric acid, creatinine, ammonium ions, and bilirubin are all examples of ________ _______ ________ present in plasma. | organic waste products |
