This is not a good/valid question as the terms used in it are not compatible I.E. Surface tension has nothing to do with a cavity within the hull (filled or not with water)
Perhaps the question was meant to be: Is the displacementof the hull increased when a cavity within the hull of a vessel is filled with water?
To this, the answer is yes, as any weight added to the vessel, no matter where it is added (inside a cavity or not) will increase the displacement.
The displacement of a vessel such as a ship is a measure of the amount of water that would normally be in the area that the ship now occupies. The weight of this displaced water would be equal to the total weight of the entire ship.
Yes, the rectum is in the abdominopelvic cavity. But, the anal canal, which is inferior to the rectum is outside of the abdominopelvic cavity.
the scrotum
Since the parietal pericardium is right outside the Pericardial cavity, then I believe you can simply say the parietal pericardium itself is located in the mediastinum in the thoracic cavity.
The visceral peritoneum, a serious membrane, lines the outside of the small intestine where it meets the peritoneal cavity.
An abdominal gestation is a pregnancy outside of the uterus and within the abdominal cavity.
upper respiratory tract is outside the chest cavity, and the lower respiratory tract, which contains gas-exchanging pulmonary tissues, is inside the chest cavity
Gonorrhea
A charged sphere with a cavity has the property that the electric field inside the cavity is zero. This means that any charge placed inside the cavity will not experience any electric force. The electric field outside the sphere behaves as if all the charge is concentrated at the center of the sphere.
An organ that is outside the abdominal cavity is known as an extraperitoneal organ. These organs are located behind the peritoneum rather than within it, providing additional protection and support. Examples include the kidneys, adrenal glands, and most of the urinary bladder.
Tension pneumothorax which is where the lung cavity fills with air and crushes the remaining good lung.
No, the external male genitalia is located outside the pelvic cavity. The penis and scrotum are external structures that are visible on the lower abdomen.
Pregnancy in the abdominal cavity outside the uterus is rare, but yes, it can happen.
