salivary amylase (ptyalin)

FALSE

TRUE
Composition of saliva
Water 99.24% and solids 0.5%
Imporatant constituents of saliva
- Ptyalin and mucin
Hydrolyzes starch and glycogen or their derivatives like glycogen into maltose
Ptyalin
Ptyalin requires presence of what anions?
Required presence of anion like chlorides and phosphates
responsible for the viscidness and viscosity of saliva
Mucin
connective tissues with a lipid matrix
Blood
Extracellular liquid matrix of blood is called
Plasma
Three major types in vertebrates
RBC, WBC, PLATELETS
– contain the respiratory pigment, hemoglobin
RBC
conjugated protein composed of four independent polypeptide chains
Hemoglobin
formation of this can make the color of blood more intensely
Oxyhemoglobin
Compound formed by the union of one molecule hemoglobin with four molecules of oxygen is called
Oxyhemoglobin
hemoglobin when it is not bound to oxygen.
Reduced hemoglobin, also known as deoxyhemoglobin or venous hemoglobin
most physiologically active tissue in the body
blood plasma
has the lowest molecular weight
serum albumin
Maintain osmotic pressure of the blood, which controls the water balance of the body
serum albumin
contain immunologically active antibodies that defend the body against diseases such as diphtheria, mumps and measles
Globulin
refers to blood that has its fibrinogen removed, which is a protein involved in blood clotting.
Defribinated blood
blood that has been treated with anti-coagulant heparin, a substance that inhibits blood clotting by preventing the formation of fibrin.
Heparinized blood
natural response to injury or damage to blood vessels which involves a complex series of events that help to prevent excessive bleeding and promote wound healing.
