Presentation transcript:

Circulatory System Blood has many functions: waste, gas and nutrient transport, temp regulation, immune response, clotting, buffering of acids and bases Blood 4-6L in body, is composed of two parts: plasma and formed elements Formed elements: erythrocytes(RBC), platelets, leukocytes(WBC)

Blood Plasma Plasma: clear extracellular fluid Plasma contains proteins that are key to survival. Albumin, globulins, fibrinogen Albumin: ph buffer and key to blood viscosity and osmolarity Globulins: solute transport, immunity

Blood Plasma Fibrinogen: sticky proteins that forms framework of clot Plasma also contains toxic nitrogenous waste products of catabolism Viscosity: the resistance of a liquid to flow, or the “thickness” of a liquid Osmolarity: the measure of dissolved solutes in the blood compared to tissue

Erythrocytes Hemopoiesis: the process to making blood Myeloid hemopoiesis: blood formed in bones RBC’s: two main functions, carry oxygen from lungs to tissue and CO2 from tissue to lungs Hemoglobin: protein in blood cell that binds to CO2 and O2, has four parts called heme’s

Erythrocytes Hematocrit: the percent of RBC’s in whole blood (42-52% men, 37-48% women) Dietary iron is very important. Each RBC contains iron, it allows the RBC to bind gases Hypoxemia: drop in RBC count causes low O2 levels. Kidneys sense hypoxemia, increase EPO production causing increase in production

Erythrocytes Hemolysis: when RBC’s die or become damaged, they rupture leaving hemoglobin and membranes that are broken down by liver and spleen Polycythemia: the over production of RBC’s usually caused by cancer Anemia: low amounts of RBC’s can be caused by many things, usually age and low levels of EPO from kidneys

Erythrocytes Sickle cell: found in African descent, high death rate, causes RBC’s to be missed shaped leads to low O2 levels and blocking of arteries
