Blood, Lymph  Anesthetic Techniques Blood  Blood is the unique fluid connective tissue in our body, and it plays a significant role in transporting various substances to different body parts. The main components of blood include red blood cells, white blood cells, blood platelets and plasma. Blood is the main component of the human circulatory system,  fulfilling many functions such as:  Regulating  Involved body temperature. in transporting hormones, nutrition, enzymes, respiratory gases and other molecules to the respective parts of the body. Lymph  Lymph is a clear to white fluid tissue composed of lymphocytes and white blood cells. Lymph is part of the lymphatic system and is generally found in the body’s lymphatic vessels and various cavities. It plays a vital role:  by transporting the white blood cells within the lymph nodes and bones.  Removing interstitial fluid from tissues.   Fighting against the diseasecausing and infectious bacteria invading the blood cells Differences between the Blood and the Lymph Lymph Blood Definition It is a colourless fluid. It is a reddish – coloured fluid. Process occurs in It is part of the lymphatic system. It is part of the circulatory system. Functions It helps in body defence and is a part of the immune system. It is involved in circulating nutrients, hormones, oxygen and carbon dioxide, wastes and other toxins. Comprised of It contains plasma and a lesser number of WBCs and platelets. It has plasma, RBCs, WBCs, and platelets. Oxygen level Carries less oxygen and digested food. Carries more oxygen and digested food. Proteins and minerals Lymph plasma lacks proteins. Blood plasma consists of proteins, calcium, and phosphorus. Supply of Nutrients Nutrients are supplied from the cells, and issued to the blood through lymphatic vessels. Nutrients are supplied to different organs. Flow Very slow compared to blood. Blood flows fast in the blood vessels. Formation of Clots Clots slowly due to the presence of less fibrinogen. Clots quickly due to the presence of more fibrinogen. Movements The movement of lymph is in a single direction. The movement of blood is in a circular motion. Thank You
