How does blood reach literally every cell in the body? There can’t be capillaries between every single cell when capillaries are also made of cells…. can there?

Question

How does this work?

Answer 1

Weird vague answers here. Capillary walls have gaps that allow fluid containing glucose and electrolytes to filter from the blood, through these gaps, and wash over cells. The cells take in the glucose and electrolytes by osmosis.

The used up fluid is then drained by a system of ducts called lymphatics which collects it all and recycles it back into the blood stream through the two big boy ducts – 1) the thoracic duct and 2) the right lymphatic duct which pour it back into the jugular veins, hence the term “jug”-ular vein (that part’s not true, but it should be).
