Question

How are blood cell able to move through narrow vessels

Answer 1

Blood cells are able to move through narrow vessels due to their flexible and deformable nature. Red blood cells, which make up the majority of blood cells, are able to change shape and squeeze through tight spaces. They can deform into elongated shapes to pass through small capillaries and then return to their normal shape once they are through.

In addition, blood flow in narrow vessels is also facilitated by the pumping action of the heart and the rhythmic contractions of the blood vessels themselves. These mechanisms help propel the blood cells through the narrow vessels and ensure a continuous flow of blood throughout the body.
