Document Summary

Blood has connective tissue, is homogeneous, and 5 liters in the body. Blood includes: plasma, ecf, formed elements (37-54%, rbc, white blood cells, platelets. Made of 7% protein, 91% water, 2% other solutes: proteins (7%, albumins, osmotic pressure, transport of steroid hormones, buffer, globulins i) Immunity, steroid hormone, fat soluble vitamins, iron, and lipid transport: fibrinogen, blood clotting, water (91%, other solutes (2%, ions i) Sodium, potassium, calcium, magnesium, chloride, iron, phosphate, hydrogen, hydroxide, bicarbonate: nutrients, glucose, aa, triglycerides, cholesterol, vitamins, waste, urea, uric acid, creatinine, breaks down rbcs (bilirubin) iii) Lactic acid (product of respiration: gases, o2, co2, nitrogen, regulatory substances i) 2 parts of blood: plasma and formed elements. Formed elements make up 37-54% of blood: platelets (<0. 1%), aka thrombocytes, responsible for blood clotting, white blood cells (<0. 1%), aka leukocytes, immune responses, red blood cells (99. 9%), aka erythrocytes, oxygen and carbon dioxide transport. 5. 5 million, while males have 4. 5-6. 3 million (per microliter).
