A sac filled with blood is typically referred to as a hematoma. It occurs when blood collects outside of blood vessels, often due to injury or trauma, leading to localized swelling and discoloration. Hematomas can form in various tissues, including muscles and organs, and may require medical evaluation depending on their size and location. In some cases, they can resolve on their own, while larger or symptomatic hematomas may need drainage or other medical intervention.
The fluid-filled sac surrounding the developing embryo or fetus is called the amniotic sac. It is filled with amniotic fluid that protects and cushions the fetus, helping to regulate its temperature and provide room for movement.
It's a vacuole.
The amniotic sac is the membranous fluid filled bubble in which the developing foetus is suspended in utero.
The extraembryonic membrane that forms a fluid-filled sac is the amnion. It helps protect and cushion the developing embryo by surrounding it with amniotic fluid.
A fluid-filled sac, such as a bursa or a synovial joint capsule, acts as a cushion to reduce friction between moving parts of the body. It helps to lubricate joints and facilitate smooth movement.
A blood-filled sac on a dog, known as a hematoma, can be caused by trauma, ear infections, or blood clotting disorders. Treatment options may include draining the sac, medication to reduce inflammation and pain, and addressing the underlying cause such as treating an ear infection. In severe cases, surgery may be necessary. It is important to consult a veterinarian for proper diagnosis and treatment.
An aneurysm is a medical condition that effects the arteries. An aneurysm is a blood filled sac that can form either from weakened blood vessels or by disease.
A fluid-filled sac that surrounds an embryo is called an amniotic sac. This sac contains amniotic fluid, which provides protection and cushioning for the developing embryo.

If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.
