Review of the components of blood/ heart function (for unit 8) Flashcards
Contains 90% water and 7% blood proteins, the remainder contains hormones, electrolytes, amino acids, waste products, enzymes, and nutrients such as glucose.
-Primary function is to transport dissolved substances across the endothelium-lined walls of blood vessels. These dissolved substances can be exchanged with other substances in the interstitial fluid.
Blood plasma
Albumins
Globulins
Fibrinogen
Types of blood plasma proteins
Synthesized in the liver and maintain total blood volume by transporting water in the blood.
- Most abundant - 60% of plasma protein
- If the amount of these decrease, causes edema.
Albumins
Alpha globulins
Beta globulins
Gamma globulins
Three types of globulins
Produced by the liver, transport fats in the bloodstream. LDL (low density lipoproteins) remove cholesterol from the liver to body cells. HDL (High density lipoproteins) remove cholesterol from the arteries.
Alpha globulins and Beta globulins
Function in the immune system as antibodies. IgA, IgD, IgE, IgG, IgM - these are specific formulas for defending the body against antigens present in disease causing microorganisms.
Gamma globulins
A plasma protein that aids in blood clotting reactions. Interact to form fibrin.
Fibrinogen
Inorganic compounds that separate into ions when dissolved in water. Sodium, chloride, calcium, potassium, phosphate, magnesium, bicarbonate.
Electrolytes
Transport oxygen and carbon dioxide in the blood. Specialized cells which do not have a nucleus, ribosomes, or mitochondria, and must, therefore, be synthesized in the body.

Erythrocytes (red blood cells)
The body’s primary defense against invading microorganisms. Primarily produced by bone marrow. Found in blood, the lymph nodes, and specialized lymphatic tissues of the body.
Leukocytes (white blood cells)
Largest blood cells, form macrophages (first cells to arrive at the site of an injury and release chemicals to attract other macrophages). Destroys invading microorganisms by engulfing the foreign cells and then releasing lysosomes that digest it.
Monocytes
20-30 perfect of white blood cells. Help cleanse the body tissues of disease-causing microorganisms as well as remove decaying cells. T-cells, B-cells, NK cells.
Lymphocytes
A group of specialized lymphocytes within the body.
-Crytotoxic- migrate from lymphoid tissue to the site of invasion, where they inject perforin into the invading microorganism. (main cause of rejection of organs)
-Helper- aids regulation immune responses. Works directly with B-cells.
-Suppressor- inhibit the immune system response.
Memory- used in the event that the same antigen presents itself again in the body.
T-cells
Differentiate into plasma cells, which are able to produce antibodies found in blood plasma.
B-cells
Seek and destroy foreign cells, normal cells infected with viruses, ,and cancer cells.
NK cells (natural killer cells)
