Digestive system, excretory system, reproductive system, and ?
space between mantle and visceral mass. Digestive, reproductive, and excretory systems all empty into mantle cavity, so basically all of its poop pours into it.
the exocrine gland.
The cloaca is a chamber that receives products from the digestive, urinary and reproductive systems. The cloaca serves as the sole posterior opening and is found in amphibians, birds and reptiles.
False. Endocrine glands are ductless glands
They are all in the Abdominal Cavity.
The Oropharynx
It is called a mold.
The cavity is an empty space which is then occupied by tissue, in this case bone marrow. i.e. your thorax is a cavity which houses your Lungs, Heart etc.....
Empty spaces within the body are commonly referred to as cavities. These include the cranial cavity (housing the brain), thoracic cavity (housing the heart and lungs), and abdominal cavity (housing the digestive organs). These cavities help protect and support the internal organs.
The cranial cavity is the empty space inside the skull. It is where the brain is kept. That makes the cranial cavity especially important, since the brain is what controls most of the processes and functions of the body.
an empty cavity or cavern due to drilling or possibly earthquake activity or volcanic activity
To my knowledge, there is not known to be an empty space in the mantle. Earthquake seismic waves travel through the Earth in different ways as they change from crust to mantle. Such a void would have probably been detected by now, as the waves would NOT travel through a void - they travel through solids and liquids (but not the solid of the Earth's core).
