Document Summary
Blood is a liquid connective tissue: blood is mostly water and therefore shares many properties of water. Water has a neutral ph and therefore blood can keep the body ph neutral. Water has a high specific heat therefore blood is useful in temperature regulation: blood is composed of: Water soluble proteins in the plasma: albumin 60%: osmotic pressure, transports lipids, hormones, and steroids. This protein helps keep cells balances and at a normal size. It can also carry lipid soluble substances and make them water soluble for transport: globulins 35%: help to transport immunoglobulin"s (cid:523)antibodies(cid:524, fibrinogen 4%: protein essential for clotting. Cells (red/white: leukocytes: white blood cells fight against infection (many subtypes of white blood cells, erythrocytes: red blood cells deliver o2 and remove co2. Cell fragments (platelets; a blood clotting component) Blood is useful to transport nutrients to tissues as well as picking up waste from tissues.
