Body Tissue----Chemical composition of the blood as it moves around the body
Lung--------------Receives O2, CO2 released
General-----------Receives CO2, O2 released
Stomach----------Water diffuses in, substances e.g. alcohol pass into blood through stomach walls
Small intestine---Digested foods – amino acids and glucose – diffuse into blood and go to liver (fatty acids diffuse into the lymph)
Liver tissue-------Removes and stores: vitamins, iron, excess lipids. Glucose removed if blood sugar levels are high, added if low. Unwanted or potentially poisonous substances are removed. Excess amino acids are absorbed and converted to urea.
Large intestine---Water, salts and vitamins are absorbed and pass into the blood.
Kidney-------------Excess water and salts are removed from the blood and excreted.
Endocrine----------Hormones secreted directly into the blood stream
