Document Summary
Blood is a connective tissue (matrix embedded with cells) Plasma proteins: stay within blood vessels (large), many types and many functions (can contribute to osmotic pressure, maintain thickness of blood, stabilize ph of blood, carry fats/other molecules, contribute to immune response, aid blood clotting) Inorganic ions: electrolytes, don"t stay in blood vessels- pass out of capillaries. Dissolved gases (o2 and co2) - pass out of capillaries. Nitrogen waste products - pass out of capillaries. Destroyed when too old in liver and spleen. Sticks to connective tissue in a blood vessel when the vessel is injured. Oxygen enters in respiratory system, binds to respiratory pigment, gets distributed by circulatory system. Plasma is 90% water and oxygen is not very soluble in water. Respiratory pigments: evolution developed means to carry oxygen more e ciently. Protein and an organic molecule and a metal atom bound together. Vertebrate rp is hemoglobin, metal atom is iron (why blood is red)
