Blood And Transport Of Nutrients

Question 1

Oxygen/ oxyhemoglobin equation

Answer 1

O2 + Hb–>HbO2

Oxygen+ haemoglobin –> oxyhaemoglobin

Question 2

Oxygen in blood transport details

Answer 2

Oxyhemoglobin= loose bond to easily realise oxygen into body to the cells
Haemoglobin in red blood cells increase body’s oxygen carrying capacity 60-70 times
Oxygen combines with haemoglobin where O2 concentration gradient is high and regales when O2 concentration gradient is low

Question 3

Path of oxygen in Blood

Answer 3

Air-> alveoli-> blood: 97% as oxyhemoglobin and 3% dissolved in plasma -> capillary-> high concentration gradient cause O2 to diffuse out of blood-> tissue fluid -> cells

Question 4

Transport of carbon dioxide

Answer 4

70% as bicarbonate ion
22% as carbaminohaemoglobin
8% as dissolved substance in plasma

Question 5

Carbon dioxide/ bicarbonate ion

Answer 5

Co2 + H2O –> H2CO3 –> H + Co3

Question 6

Carbon dioxide in blood transport details

Answer 6

Blood flows in capillary and co2 diffuses into blood due to concentration gradient
Most reacts with water to create carbon acid which then dissociates to from hydrogen and bicarbonate ions, therefore carrying carbon dioxide in the blood
carbaminohaemoglobin breaks down to realise co2
Hydrogen and bicarbonate ions from to create carbonic acid which then breaks down into water and carbon dioxide to release the gas

Question 7

Path of carbon dioxide

Answer 7

Cells-> tissue fluid -> capillary-> blood: 70% bicarbonate ion, 22% as carbaminohaemoglobin and 8% dissolved in plasma -> capillary-> alveoli ->air

Question 8

Blood- colour

Answer 8

Bright red= oxygenated- rich with oxyhaemoglobin

Dark red/ purple= deoxygenated blood- rich with CO2

Question 9

Transport of nutrients and waste

Answer 9

Dissolves in plasma
Ions- Na, K, Ca
Inorganic- glucose, a.a
Organic- urea

Question 10

Transport of Oxygen

Answer 10

97% as oxyhemoglobin

3% dissolved in Plasma
