Thoracic Cavity's Main Occupant
Thoracic Cavity's Main Occupant
The lungs are the largest organ in the thoracic cavity, responsible for gas exchange.
Heart's Role
Heart's Role
The heart pumps blood throughout the body, circulating oxygen and nutrients.
Air and Blood Pathway
Air and Blood Pathway
Bronchial tubes connect the trachea (windpipe) to the lungs, carrying air and blood vessels transport blood to and from the lungs.

Study Notes
Thoracic Cavity
- The heart occupies the majority of the thoracic cavity.
- The main function of the heart in the thoracic cavity is to pump blood throughout the body.
Respiratory System
- The trachea is responsible for conducting air to and from the lungs in the thoracic cavity.
Circulatory System
- The esophagus is responsible for the passage of nutrients from the head to the abdomen in the thoracic cavity.
Thoracic Cage
- The main purpose of the domed shape of the thoracic cage is to provide protection for the heart and lungs.
- The main function of the joints and thinness of the ribs in the thoracic cage is to allow for flexibility and expansion during breathing.
Ribs
- True ribs are connected to the sternum through their own costal cartilages.
- False ribs have cartilages that are connected to the cartilage of the rib above them.
- Floating ribs do not connect, even indirectly, with the sternum.
- Ribs 7-10 are considered as false ribs.
- The head of the rib articulates with the corresponding transverse process of the vertebra.
- The neck of the rib functions as a pivot point, allowing the rib to move up and down during breathing.
- The costal groove is located on the underside of the rib.
- The 7th rib is the broadest and most sharply curved.
- The 5th rib has a rough area on its upper surface called the tuberosity for serratus anterior.
- Ribs 3-6 have only one facet on the heads and articulate with a single vertebra.
- Ribs 3-6 are classified as typical ribs.
- Ribs 7-10 form a continuous, articulated, cartilaginous costal margin with the costal cartilages just superior to them.
Intercostal Spaces
- There are 11 intercostal spaces in total.
- The true ribs anchor the anterior end of the rib to the sternum, limiting its overall movement.
- The 4th intercostal space lies between ribs 4 and 5.
- The subcostal space below the 12th rib is associated with the 12th thoracic nerve.
