Large Ocean vessels are designed to have a flat bottom and high sides so they can maximize buoyancy. You're Welcome
Submarines are designed to maintain positive surface buoyancy only so long as their Main Ballast Tanks (essentially large compartmented air tanks along the length of the boat, on both port and starboard sides). When the air is released and water is allowed to fill the tanks, the boat submerges. To surface again, compressed air is released into the MBT's, and the boat again regains positive buoyancy. Surface vessels are designed to maintain positive buoyancy only, though they of course sink lower in the water or rise depending on the amount of weight they carry.
to help keep buoyancy
Histamine causes the dilation of the small blood vessels while constrict the large blood vessels.
The buoyancy of Titanic, and other large vessels, is a carefully calculated amalgam of air, solid materials (wood or metal) and ballast. Thomas Andrews, who took courses in naval engineering understood this and correctly predicted Titanic's sinking.
The extreme salinity - saltiness - means the water there has a higher density than regular sea water. and the higher the density the greater the buoyancy.
vitilline vein
large vessels on top of the heart are the veins.
a tube in you body that Carry's blood
The lungs have a large number of blood vessels because blood vessels carry oxygen to the lungs and the lungs need a lot of oxygen.Because it makes the transfer of oxygen from the lungs to the bloodstream quicker.
Blood vessels are structures that carry the blood from the heart to all the tissues of the body and then back to the heart.arteries: large blood vessels running away from the heartveins: large blood vessels running toward the heart
These are basic amphibious assault vessels. They are designed to carry large numbers of troops and the supplies and equipment needed. The LST and LSD are two of the main vessels that do this, having the ability to run up close to the beach and drop them almost right on the sand.
The blood vessels that are involved for supplying and draining blood from the small intestine are called the superior mesenteric. The blood vessels that supply and drain the large intestines are called the inferior mesenteric.
