If the heart becomes damaged or weakened, how will this affect the body’s systems?
jek_recluse [69]
Think of blood as a gas/ fuel for the car ( your body). If there is no fuel, there's no movement (dead) so when the fuel tank is damaged the car won't function properly. 
 So if the heart becomes damaged, or weakened it would start making blood clots and damage the organs that need blood to function properly. The circulatory system wouldn't function properly and because other organs depend on the circulatory system it would cause a chain reaction, affecting other body systems. <span />

cluponka [151]

The mammalian tail and the human coccyx, the leaves of pitcher plants and cacti, are homologous organs while, the flippers of penguins and dolphins, as well as the shells of turtles and crabs are analogous structures.

<h3>What are homologous organs?</h3>

Homologous organs are those that are similar in structure but operate differently. They resulted from divergent evolution.

Divergent evolution occurs when species are closely connected to the same ancestors but develop similar structures that perform different tasks in different environments.

Analogous Organs are organs from various creatures that, despite their appearance, perform the same function.

In the given case, the mammalian tail and coccyx, as well as the leaves of pitcher plants and cacti, are homologous organs, whereas penguin and dolphin flippers, as well as turtle and crab shells, are analogous structures.

Thus, these are the different instances of homologous and analogous organs.
