thorax = the part of the human body between the neck and the diaphragm, partially encased by the ribs and containing the heart and lungs; the chest.
diaphragm = a body partition of muscle and connective tissue separating the chest and the abdominal cavities.
the lungs is where gas exchange take place,
the thorax is where the lungs are located
The diaphragm. The diaphragm.
Between the thorax and abdomen
In a beetle the part of the body between the head and abdomen is called the thorax. The thorax contains important body structures.
The difference between the thorax and the abdomen is the position they lie in. The thorax lies between the head and the abdomen while the abdomen lies between the thorax and the pelvic area.
Diaphragm is the the prime mover for the inhalation. It is a dome shaped partition between the thorax and the abdomen. It gets some what flat as it contracts. The volume of the thorax increases. There by the air is pulled in the thorax.
The tHorax
Your diaphragm is located below the heart. This is the partition, between the thorax and abdomen.
The head is connected to the thorax and the thorax connects to the abdomen.
In humans and other mammals the thorax and abdomen are separated by a sheet of muscle called the diaphragm. In insects like wasps and bees where there is a narrow region between the thorax and the abdomen this is called the petiole.
The intercostal muscles between the ribs control the movement of the thorax and rib cage. The diaphragm, which separates the thorax from the abdomen controls the volume of the thorax. As the intercostal muscles contract the rib cage is drawn upwards and out, the diaphragm flattens so the volume inside the thorax increases therefore, air is drawn in.
The deep thorax muscles are the deep muscles of the thorax that promotes the inspiratory phase of breathing. When breathing the diaphragm contracts, producing a negative pressure, which forces are into the lungs.
Abdominopelvic cavity lies below the diaphragm and can be subdivided into the abdominal cavity and the pelvic cavity.
