Why hydrostatic pressure is high at arterial end of blood capillary?

Hydrostatic pressure is high at the arterial end of a blood capillary because this is where blood enters the capillary under high pressure from the heart.

This process is essential for delivering oxygen and nutrients to cells and removing waste products.

Do dogs and humans have a similar bone structure?

The simple answer is 'yes' because back in time we all share a common evolutionary ancestor. However since this common ancestor evolution has changed the shapes and structure of bones. For instance we can see which bones are the same as ours in a bird wing but they look very different to ours. Similarly a horse's leg is actually a finger/toe bone when compared to our hands/feet. Further the bones in our ears can be traced back via fossils to jaw bones. Thus while we all have the same basic skeletal blueprint, bones look very different in different animals today.
