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 search

Explanation / 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.
