The diagram below shows part of the capillary bed in an organ of the human body. Some of the blood arriving at the capillaries at points labelled A, moves out into the spaces between the tissue cells. Study the diagram and answer the question that follows:

When the liquid from the blood surrounds the cells, what is it called?

The diagram below shows part of the capillary bed in an organ of the human body. Some of the blood arriving at the capillaries at points labelled A, moves out into the spaces between the tissue cells. Study the diagram and answer the question that follows:

Name any one important component of the blood that remains inside the capillaries and fails to move out into the spaces.
