Question
Name a hormone produced by the following: heart, kidney, adipose tissue and bone Chapter 17 (Blood) What happens to a given blood type (A, B, AB, or O) when mixed with anti-A, anti-B and anti-Rh? Which agglutinins and agglutinogens are presentin different blood types? Why is O-universal donor and AB+ a universal recipient? Name some regulatory, protective and distribution functions of blood Name the 7 blood cells and the description and function of each What is erythropoiesis, what triggers it? What is a reticulocyte? What information does its count provide? Physical and chemical characteristics of blood (color, viscosity, pH) Polycythemia: causes and effect on blood pressure, volume, viscosity, flow, pressure and hematocrit -57 9/10 to searchExplanation / Answer
1. Blood type A : agglutinates in presence of Anti-A serum as the serum has antibodies for antigens present on type A blood group. no other serum can results in agglutination of type A.
Blood type B: agglutinates in presence of Anti -B serum
Blood type AB: agglutinates by both Anti A and Anti-B serum, As blood type AB express both kind of antigens on their surface
Blood type O: agglutination doesnot takes place in either of the serum (anti- A, Anti - B and Anti -Rh.
2. Antigens on the surface of Red Blood Cells are called as Agglutinogens and Antibodies that react against them is called as agglutinins
blood group A : expresses A agglutinogen and anti-B agglutinins
blood group B : expresses B agglutinogen and anti -A agglutinins.
blood group AB: expresses both A and B agglutinogen but no agglutinins.
blood group O: expresses no agglutinogens but both Anti A and anti B-agglutinins.
3. Blood group O doesnot expresses any of the agglutinogens (antigen) so no agglutination when mixed with blood type A,B, or AB. therefore blood type O can be accepted by any of these blood groups and hence blood group A is called as universal donor
Blood group AB expresses both the agglutinogens but no agglutinins (antibodies) hence can accept any of the three blood groups (A, B, O) and is reffered as universal acceptor.
4. Blood functions:
Regulatory :
It controls body temperature
Maintains pH of the Body
Protection:
Maintains adequate fluid level
Prevents blood loss by initiating blood clots by platlets and blood proteins
Acts against body infections
Distribution:
Delivers Oxygen from lungs to cells
Carbon dioxide produced during metabolism is transported back to lungs by blood which is then exaled
Blood provides the cells with nutrients, transports hormones and removes waste products.
5. Type and function of blood cells:
Erthrocytes/RBCs: Haemoglobin of RBC carries oxygen
Thrombocytes: Helps in platlet genesis which helps in blood clotting
Leukocytes: Destroys foriegn substance and produce WBC
Eosinophils: Act as phagocytes, reside in intestinal and pulmonary mucosa
Basophils: Release heparin ( prevents blood clotting) and histamines (vasodilator)
Lymphocytes: Yields antibodies for cell immunity
Monocyte: Acts as phagocyte.
