Document Summary

Blood exists the heart via arteries which branch until becoming capillaries. Connective tissue where the blood cells (formed elements) are suspended in a fluid matrix called plasma. Erythrocytes red blood cells that transport oxygen (45% of blood samples) Buffy coat thin layer present at the erythrocyte-plasma junction. Leukocytes white blood cells that act to protect the body. Hematocrit the percentage of erythrocytes in the blood. 5x more viscous than water ph between 7. 35-7. 45. 8% of body weight average volume in males is 5-6l/females 4-5l. Mostly water but also has 100s of dissolved solutes (including electrolytes) Plasma proteins produced by liver (except hormones & gamma globulins) Acts as carrier to shuttle molecules through circulation. Major blood protein contributing to plasma osmotic pressure. Plasma osmotic pressure the pressure that helps to keep water in the bloodstream. 36% of plasma proteins alpha/beta: transport proteins gamma: antibodies. 4% of plasma proteins forms fibrin threats of blood clot.
