A membranous sac is, as it says, a sac with a membrane. What it is specifically varies. Bronchi in the lungs are membranous sacs and the amniotic sac on a baby is membranous.
The amniotic sac is the membranous fluid filled bubble in which the developing foetus is suspended in utero.
Peri 'cardial or Pericardium, is the membranous sac enclosing the heart.
Golgi apparatus is a set of membranous sac-like structures in cells that are responsible for processing, modifying, and packaging proteins and lipids for transport within or outside the cell.
The membranous sac that contains catalase is called a peroxisome. Peroxisomes are organelles found in eukaryotic cells that break down various molecules, including hydrogen peroxide, using enzymes like catalase. They also play a role in lipid metabolism and detoxification reactions.
At 12 weeks and 5 days, the presence of a live fetus alongside an empty gestational sac typically indicates a situation where the sac has not developed properly. The chance of the empty sac developing further is quite low, as it usually suggests a missed miscarriage or abnormal development. In such cases, the body often reabsorbs the empty sac over time. It's essential to consult with a healthcare provider for a more accurate assessment and to discuss potential next steps.

vesicle/ vacuole
The membranous sac formed by pinching off pieces of cell membrane is known as a vesicle. Vesicles play a crucial role in transporting molecules within the cell and to and from the cell membrane. This process is called vesicular transport.
A cyst is an abnormal sac that contains fluid, gas, or semisolid material. They can develop in different parts of the body and may or may not cause symptoms, depending on their size and location. Treatment for cysts usually involves monitoring them or draining them if they become problematic.
Abnormal accumulation of fluid in the scrotal sac is called hydrocele.
The membranous sac that contains catalase is called a peroxisome. Peroxisomes are organelles found in eukaryotic cells that break down various molecules, including hydrogen peroxide, using enzymes like catalase. They also play a role in lipid metabolism and detoxification reactions.
A lysosome is a sac of digestive enzymes, used to break down monosaccharaides and disaccharides. Lysosomes are found in animal cells and are also called suicide sacs.
