A Bowman's capsule is part of the filtration system in the kidneys. When blood reaches the kidneys for filtration, it hits this area first, with the capsule separating the blood into two components: a cleaned blood product, and a filtrate that is moved through the nephron, another structure in the kidneys.

The incubation period for wood ducks varies, but is usually between 28 and 32 days. The entire clutch hatches in less than 24 hours. The hen will leave the nest box with her new brood on the first morning after the initial egg was hatched.hen the entire clutch of eggs has been laid, the hen will begin full-time incubation. This assures that all the eggs have a good chance to hatch together on the same day. During the incubation period, the hen will leave the nest box twice daily to feed (morning and evening) for about 30 minutes.
A mother duck sits on her eggs for 20 to 23 hours a day, taking an average of three breaks, each lasting around an hour at a time. When she does leave her nest, the duck hen covers her eggs with additional down and nesting material to help keep the eggs warm in her absence. The incubation period lasts an average of 28 days, about a month. With the mother duck spending so little time away from the nest, she relies on stored fat to survive. A couple of days before the eggs are ready to hatch, small cracks begin to appear, and the ducklings will begin peeping from inside their eggs. Then, in a span of 24 hours, all the ducklings will hatch from their eggs, using a small sharp bump on their bills called an egg tooth..
