Nurse Beth correctly identifies which of the following as belonging to the dorsal cavity?
a- Mediastinum.
b- Mouth.
c- Vertebral canal.
d- Reproductive organs.
Answer C.
The dorsal cavity is divided into the cranial (skull) and vertebral canal (spinal cavity).
The mediastinum and reproductive organs are located in the ventral cavity.
The mouth is located in the oral cavity.
The abdominal cavity is a large space in the middle of the body, above which there is a chest cavity that contains the heart, lungs, trachea and esophagus.
The cavities, in mammalian and human animals, separate the diaphragm muscle that helps in breathing. In the rest of the vertebrates, the cavities are connected without a break.
The members of the thoracic cavity are surrounded by the thoracic cage that protects them, while the members of the abdominal cavity of the back hide the vertebrae and the layers of muscle and skin from all sides: front, back and sides.
The abdominal cavity contains many important organs that are the bulk of the digestive system, also the urinary system and the reproductive system and other organs.
The organs of the gastrointestinal tract are located in the abdominal cavity: the stomach, in the upper left side of the cavity, which resembles a flexible cylindrical sac that folds from the right and opens at first the esophagus and at the end of the intestine begins.
The stomach is constantly moving and the food is mixed with its digestive system and turned into a heavy liquid.
The liver is located on the right side of the abdominal cavity under the diaphragm directly, a large member red color is composed of two lobes, one large on the right and the other small on the left.
The entire urinary tract is located in the abdominal cavity. The kidneys are located in the dorsal part of the cavity, under the digestive system and protected by a cushion of dorsal tissues and muscles.
The kidneys draw harmful substances from the blood in the form of urine, which is transferred by the ureters (two tubes) to the bladder.
The bladder is a round sac located at the bottom of the abdominal cavity, and the urine is stored until it is discharged outside the body by urination.
Another member is the spleen and is located behind the stomach, and the color is light red, which stores a quantity of blood to benefit the body when needed.
The reproductive system includes ovarian females and ovarian and uterine ducts that are enlarged during pregnancy and fill a large space in the abdominal cavity. In males, the testicles are located outside the abdominal cavity, and their channels and some helper glands are located at the bottom of the cavity.
