K.C.S.E Biology Q & A - MODEL 2005PP1QN11
The diagram below represents a part of the rib cage.
​a) Name the parts labeled W, Y and Z.
W …………………………………………………… Y ……………………………………………………. Z …………………………………………………….. b) How does the part labeled Z facilitates breathing in?
answers
​a) W – Spinal column / reutebral column
Y – Sternum Z – Intercostal muscles. b) The external intercostals muscles contract while the internal intercostals. Muscles relax. This movement pulls the ribs upwards and outwards. The diaghragm muscles contracts (flattens).The thoracic volume increase while the pressure reduces, leading to atmospheric air rushing into the lungs through the nose and trachea hence inflating the lungs.
