Document Summary
Wbc"s: defense against microorganisms and removal of debris. Plasma: composes the majority of blood(90% water) and is a transport medium for many organic and inorganic substances. Plasma can absorb and distribute heat generated during metabolism. Usually do not exit the capillary(large in size). Establish an osmotic gradient between the blood and interstitial fluid. The major role of rbcs is to transport o2 to the tissues and co2 to the lungs. They are flat, disc shaped and biconcave cells. Our rbc count would increase because of the low atmospheric o2, which signals the kidney to make more epo. The athlete"s blood will become thicker and have a higher viscosity. This affects the heart function because the heart will have to work harder to push the thicker blood, so a blood clot or stroke may occur. They are the first defenders, very important during inflammation, and clean up debris. They are called neutrophils because their granules stay neutral. (neutral-pink stain)
