Blood Connective tissue
Blood : Plasma (straw coloured transparent fulid) + Cells
55% + 45%
Specific density : 1.050-1.060
Gases Nutrients Wastes Hormones
Transport
Transportation
pH balance
Regulation Blood
Temp. Control
Protection
Coagulation Immunity (WBC)
Reduce loss of blood protect against bacteria
Composition of blood :
Plasma watery liquid extracellular fluid
Cells
Plasma : Plasma = blood – Cells (formed elements )
Composition :
Water:91 %
Plasma proteins (7%) : albumin , globulin fibrinogen
Other (2%)
, electrolyte : Inorganic salt
Nutrients : amino acids glucose , faaty acids , minerals
Gases : O2 ,CO2 and N2
Regulatory substances : enzyme, hormones ,vitamin
Waste products : urea ,uric acids. Ammonia , creatine , creatinine ,bilirubin etc
1) Plasma proteins :
a. Albumin most abundant 54%
Formed in liver
Acts as carrier molecule for lipids and steroids hormone
b. Globulins 38% of plasma protein
Mostly Formed in liver
Some extent in lymphoid tissue
Immunoglobulins (antibodies )
c. Fibrinogen 7%
Formed in liver
Helps in coagulation
Functions :
Maintaining viscosity, osmotic pressure and total volume (albuminn & fibrinogen)
Transport hormone, ion and drugs.
Fibrinogen blood clotting
Antibodies (b lymphocyte) imp role in immunity
2) Others :
a)Inorganic ion : Na+, K+, Ca+2 Mg+2 & Cl- (Osmotic pressure & muscle contraction ),
generation & transmission of impulse formation of secretions & maintenance of acid base
balance )
b) Nutrients: glucose, AA, FA
Provide energy, heat reapirs and replacement
c) Hormones: secretions from endocrine glands
Waste products: formed in liver (by metabolism)
Connved to kidney by blood for elimination
Gases : O2 and CO2 carrry by blood by forming a complex with haemoglobin
