- Superior: root of the neck, 2-3 cm above the level of rib one
- Inferior: The thoracic surface of the diaphragm inferiorly

Where are the lungs located in the body?
To seek answers, the Doherty Institute team worked with immunologists and biologists from the Australian Organ and Tissue Authority and the Walter and Eliza Hall Institute of Medical Research, both in Australia.
In which cavities are the lungs located quizlet?
The thoracic cavity contains the heart and the lungs. What are the cavities within the thoracic cavity? There is the superior mediastinum, the pleural cavity and the pericardial cavity within the mediastinum.
Are the lungs located in the ventral cavity?
The ventral cavity is at the anterior, or front, of the trunk. Organs contained within this body cavity include the lungs, heart, stomach, intestines, and reproductive organs.
Which of these cavities contains the lungs and heart?
The thoracic cavityThe thoracic cavity contains the lungs and the heart, which is located in the mediastinum. The diaphragm forms the floor of the thoracic cavity and separates it from the more inferior abdominopelvic cavity.
What's in the ventral cavity?
These anatomical terms can also describe different body cavities. The dorsal cavity contains the spinal cord, central nervous system, and spinal column, whereas the ventral cavity consists of the thoracic, abdominal, and pelvic cavities.
Where are the lungs located?
The lungs are located within the chest cavity on either side of the heart. Each lung reaches from the collarbone to the border between the chest and abdominal cavities. The diaphragm, the muscle that helps the lungs take in air, sits below the lungs on top of the abdominal cavity.
Why is the left lung smaller than the right?
The human lung is usually between 10 and 12 inches long. The left lung is slightly smaller than the right lung because the right lung contains three sections called lobes, whereas the left lung only has two lobes. The left lung must be smaller to accommodate the heart's position.
Which cavity is the largest in the body?
Within the axial portion of the body, there are several body cavities that function to hold and protect internal organs. The ventral cavity and the dorsal cavity are the largest body cavities and they are divided into smaller cavities.
Which cavity is located in the lower half of the trunk?
Abdominopelvic cavity : located in the lower half of the trunk, and stretches from the bottom of the diaphragm to the floor of the pelvis. It is divided into the upper abdominal cavity and the lower pelvic cavity. Abdominal cavity : holds the digestive organs and kidneys.
What are the two cavities in the middle ear?
Orbital Cavities : there are two orbital cavities, each containing the eyeball and nerves, blood vessels, and muscles related to the eye. Middle ear cavities : each cavity contains the malleus, incus, and the stapes, which are known as the middle ear bones.
What are the cavities in the head?
Apart from the cranial cavity, cavities located within the head include the nasal cavity, the oral cavity, the orbital cavities, and the middle ear cavities. Nasal cavity : located inside the nose, and divided into two nasal passages by a wall called the nasal septum.
What is the thoracic cavity?
Thoracic cavity : located in the chest (upper part of the trunk) and contains the heart and the lungs. The thoracic cavity is subdivided into smaller cavities. The right pleural cavity contains the right lung, and the left pleural cavity contains the left lung. A region in the thoracic cavity called the mediastinum separates the lungs.
What are the two parts of the human body?
Body Cavities. The human body is divided into an axial portion and an appendicular portion. The axial portion of the body includes the head, neck, and trunk. The appendicular portion of the body includes the upper and lower limbs.
Which cavity holds the digestive organs and kidneys?
Abdominal cavity : holds the digestive organs and kidneys. Pelvic cavity : holds the reproductive organs, the urinary bladder, and terminal end of the large intestine. “Body Cavities Frontal View” by OpenStax is licensed under CC BY 4.0.
