Cells, organs, and systems of kiwis
Transcript of Cells, organs, and systems of kiwis
kiwi bird The kiwi bird is quite peculiar in many ways.
It lives exclusively in New Zealand, cannot fly,
et cetera. But in this presentation we will explore
it's inner faculties, specifically it's cell orginazation, organs, and systems. This is a generic animal cell. The kiwi we know today evolved up to 80 million years
ago. They can live up to 40 years old, and they lay eggs 20% of their own body weight. Each component serves a different task. The cell membrane
protects the inner
part of the cell. The vacuoles store food,
water, waste, and minerals. The cytoplasm is the area within
the cell. The mitochondria produces
the energy currency of the cell. The nucleus is the "brain"
of the cell. It controls the
overall action of the cell. The kiwi bird's organs are about as you would expect:
kiwis have, in addition to the organs shown below, as far as we can tell, a stomach, lungs, a liver, intestines, a gizzard, a pancreas, an esophagus, and a kidney. The kiwi's nervous system works much as ours does, using a network of nervous cells to send messages throughout the body,
but their digestive system is different, involving a crop, where the food waits to be digested, a gizzard, where muscular motions grind up the food, the small intestine, where food is processed, and then it is finlly pooped out. Kiwi birds eat worms, fruit,
seeds, fungi, insects, larvae, and other assorted invertebrates. WOOOOO!!!!!!!!!!!!!!!!!!!!!! The skeletal system of a kiwi is different from most birds because the kiwi has much longer legs. The wings are constructed the same but are unused as kiwis are flightless birds.
