featal dissociation curve

absorbs oxygne from mother placenta, ity has a high effinity for oxygen and curve shifts to the left

1 of 8

lugworm dissociation curve

lives in the sea dowsnt have a lot of oxygen, curve shifts to the left as it has a high effonity for oxygen

2 of 8

llama dissociation curve

lives in high alitiutdes has a high effinity fior oxygen shifts to the left as it produces more red blood cells

3 of 8

myoglobin dissociation curve

shidts to the left as it is more stauratied i oxygen compared to haemoglobin and acts as an enrgy storage in muscles

describe chlorine shidt

co2 diffuses into the RBC and comines with water to form carbonoic acid, carbonoic acid dissociates into h+ ions and HCO- ions with catalyse of carbonoic anhydrase, HCO3- ions diffuse out of the red blod cells into the plasma

5 of 8

what does the HCO3- ions come in conatct with when diffuse out of the red blod cells into the plasma

it comes in contact with na+ ions thta have dissociated form nacl and nach, h+ ions dissociate from oygen and hamolglobin, h+ ions combine woth the haemoglob to form haemoglobonic acid, ocygen diffuses into cells and cl- diffuses in

decribe the movementt of intercellualar fluid

when blood reaches the cappileries a hydrostatic pressure pushed the fluid in the blood out if the walls into the spaces, opposing forces and reduced water potentila are caused by plasma proteins,

7 of 8

what happens after the hydrostatic pressure is larger than the osmostic pressure ih

the water leaves by osmosis, at the endo of the capillary bed the diffusion gradiesnt of the solvents favour the movemeht wiothin the capillary bed
