transportation problems

The food is digested into the simplest of the forms in t he digestive system. Blood carries the digested food or the nutrients absorbed from the intestine to the liver and then to other parts of the body. The food transported includes glucose, fatty acids, amino acids, glycerol, et..

Food is manufactured in the form of carbohydrates (sucrose) in the leaves. Thus, food is transported as sucrose along phloem. From the leaves the prepared food has to be transported to the roots, the younger top regions of the plant, the flowers and fruits. Thus, the food has..

Oxygen Transport - Oxygen is transported in a combined state. The haemoglobin pigment (Hb) has an affinity for oxygen. In the lungs, it combines with oxygen and forms HbO 2 , oxyhaemoglobi..

Most of the oxygen is transported in a combined state. Some of the oxygen is present in solution in the blood. For each decilitre of blood, 4.6ml oxygen enters the blood in the lungs. Of this only 0.17ml remains in the plasma in the solution form. Remaining enters the red blood cells and..

Ascent of Sap - Transport of Water - Plants absorb water from the soil through the roots. Thus, water has to be transported upwards to the other parts of the plant. This upward movement of water is called ascent of sap . It is called the sap as it contains many dissolved mineral..
