Lecture: Physiology of Blood I. BLOOD GROUPS System AB0 Agglutinogens A, B – on membrane of RBC A – acetyl-galactosamine B – D-galactose H – acetyl-glucosamine – maternal substance 6 blood types: A 1, A 2, B, A 1B, A 2B, 0(H) Agglutinins anti-A and anti-B Blood group Agglutinogen (RBC) Agglutinin (plasma) Circulatory system and the heart. Red Blood Cells Purpose: To restore oxygen carrying capacity in patients with anaemia or blood loss. The lungs and pulmonary system. • Wastes from cells: urea, CO2 (mainly as HCO3-in solution in the plasma).Temperature Regulation: by altering the blood flow through the skin. Circulatory and pulmonary systems. The Red blood cells bind to oxygen and carry oxygen from the lungs to all the cells in the body. 5. of blood, and for every 600 red blood cells, there are about 40. platelets and one white cell. • Oxygen: by red blood corpuscles (oxyhaemoglobin - 4 x O2 molecules/haemoglobin). 6. Hemoglobin. The different components that make up blood. These help fight infections and aid in the immune process. 4-Components of Blood Description: Students will explore what our blood is made of in this lab. Plasma, white blood cells, red blood cells, platelets. We will also look at how blood flows in and out of the heart. All blood components must be transfused through a filter designed to remove clots and aggregates (generally a stan-dard 150- to 260-micron filter). The components of human blood are: Plasma. The fluid medium for transport. 2007 American Red Cross, Mid-Americaversion 2007-Oct-29 #02-0050-MA. Average volume: 220 -340 mL Storage temp: 2 to 6 oC Expiry: 35 days (14 days if irradiated) Extra info: HCT 0.5 -0.7L/L Hb > 40g MUST Be Compatible with ABO of recipient Components of blood. These carry oxygen from the lungs to the rest of the body White blood cells (leukocytes). Red blood cells. Heart – pumps blood Blood vessels: arteries – carry blood to organs and tissues veins – return blood to the heart capillaries – allow for transport to and from tissues Blood - ? There are about one billion red blood cells in two to three drops. Blood and blood components should be mixed thoroughly before use. Whole blood: blood collected before separation into components Components: parts of whole blood that are separated Closed system: a sterile system of blood collection Open system: when the collection is exposed to air, decreasing expiration date In the plasma are the components of the blood that protect the body from infections and clean up garbage in the tissues. Components of the Hematologic System •Composition of blood –Cellular components (~45%) •Erythrocytes (red blood cells) –Carry O 2 and remove CO 2 –120-day life cycle Leukocytes (white blood cells) –Defend the body against infection and remove … Functions of Blood System Transport: to and from tissue cells • Nutrients to cells: amino acids, glucose, vitamins, minerals, lipids (as lipoproteins). Students will get to see a demo of what the components of our blood look like (or they can make their own ‘blood’ jar, materials will be listed if you would like that option.) Blood Components. Components, Characteristics, Functions of Blood A. Unlike the heart and the blood vessels, which are organs, blood is a complex tissue. The liquid component of the blood in which the following blood cells are suspended: Red blood cells (erythrocytes). Blood and blood components must be inspected immedi-ately before use. Major Components of Blood 1. formed elements - the actual cellular components of blood (special connective tissue) a. erythrocytes - red blood cells b. leukocytes - white blood cells c. platelets - cell fragments for clotting 2. blood plasma - complex non-cellular Google Classroom Facebook Twitter. If, upon visual inspection, the container is Components of the Cardiovascular System. Email. Blood cells are made held together in a yellowish, watery fluid called plasma. 4. The components include: Red blood cells, white blood cells and platelets.
