Document Summary
Blood clotting: c/c types of clots, seq, iov clot formation. Immune system: c/c innate and acquired immunity. Innate immunity: c/c barrier and cellular defenses, seq immune response. A bit about blood components of blood. ~55% of blood is plasma pale yellowish with many components. Regulate fluid in plasma vs interstitial fluid. Albumins regulate ph and osmotic balance. Apulipoproteins lipid soluble proteins for lipid transport. Fibrinogins clotting: (serum plasma without fibrogens. Nutrients, waste products (co2), gases (o2), hormones. Divide one stays stem, one specializes. Most numberous blood cells by far ~25 trillion in average adult (5-6 million / ul of blood) Flexible biconcave disks thicker on sides than in middle. Specialized for o2 transport hemoglobin (protein) inside rbcs to carry o2 (2) leuthocytes. Not confined to circulatory system can travel to interstitial fluid and lymph nodes (3) platelets. Not whole cell formed via pinching fragments of large cells in bone marrow. 2 types (1) platelet plug formation temporary clot.
