Birds typically have nine air sacs: two cervical air sacs, two anterior thoracic air sacs, two posterior thoracic air sacs, two abdominal air sacs, and one interclavicular air sac. These air sacs help birds efficiently exchange gases during respiration and aid in maintaining their lightweight body structure for flight.
Blood contains more oxygen than air sacs. Oxygen from inhaled air diffuses across the walls of the air sacs into the bloodstream, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
The endoplasmic reticulum look like flattened sacs.
The small sacs are alveoli which is where oxygen and carbon dioxide are exchanged
Pollen grains have air-sacs to help them float in the air and be carried by wind or insects for pollination. The air-sacs provide buoyancy and allow the pollen grains to be dispersed more effectively to reach other flowers for fertilization.
Black widows can lay up to 400 eggs in a single egg sac, but on average they have around 250 eggs. Once the eggs hatch, the baby black widows will usually stay close to the mother until they are old enough to fend for themselves.
allows male to produce a mating call.
In worms, sperm sacs serve as the storage site for sperm produced by the male reproductive system. These sacs store the sperm until it is transferred to the female during mating, allowing for efficient fertilization of eggs.
Certain species of orb-weaving spiders, such as the wasp spider (Argiope bruennichi), are known to lay spiky or spiny egg sacs. These spiky structures help protect the eggs from potential predators.
Ink sacs can be combined with wool to make black wool. They can also be combined with 1x Bonemeal to make grey dye, and 2x Bonemeal to make light grey dye. You can also use an ink sac on a sheep to dye it black, meaning all wool shorn from it will be black.
They Love It!
They often dump the egg sacs before they hatch.
A black widow spider has eight eyes. The eyes are located in the front of the head and are arranged in two rows. Black widow spiders are very protective of their egg sacs but rarely bite humans.
As soon as she finishes excreting it from her poison sacs.

The bronchi continue to divide into smaller and smaller branches until they end in air sacs. The air sacs in the lungs are called alveoli.
