What is the thorax and what does it do?
The vertebrate thorax contains the chief organs of respiration and circulation—namely, the lungs, some air passages, the heart, and the largest blood vessels (see thoracic cavity). Below, it is bounded by the diaphragm. The bony framework is encased with muscles, fat, and cutaneous tissues (skin).
Why is the thorax important?
Your thorax is an important structure, the bones and ligaments protecting vital internal organs underneath. But it’s also where we get most of the rotation of our trunk. … The nerves from our thorax supply the abdominal muscles; these muscles protect our lower back and abdominal organs.

Article first time published onWhat is the lung and thorax?
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
Which bones protect the lungs?
The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs. Bones are made up of a framework of a protein called collagen, with a mineral called calcium phosphate that makes the framework hard and strong.
Is chest CT scan harmful?
It can damage the DNA in your cells and raise the chance that they’ll turn cancerous. These scans expose you to more radiation than other imaging tests, like X-rays and mammograms. For example, one chest CT scan delivers the amount in 100 to 200 X-rays.
Why would a doctor order a chest CT scan?
CT scans of your chest can help your doctor diagnose, or rule out, various lung impairments. Some of these include blood clots, lung tumors or masses, excess fluid around the lungs (pleural effusion), emphysema, COPD, pneumonia, scarring of the lungs, tuberculosis or a pulmonary embolism.
How is CT thorax done?
In a CT scan, an X-ray beam moves in a circle around your body. It takes many images, called slices, of the lungs and inside the chest. A computer processes these images and displays it on a monitor. During the test, you may receive a contrast dye.
What are the three sections of the thorax?
The insect thorax consists of three segments (called the prothorax, mesothorax, and metathorax), which may be fused but are usually recognizable.
Is the thorax a bone?
Thorax —The bones that surround and form the chest cavity. The thorax includes the sternum and the ribs. True ribs —The first seven ribs, 1-7, directly attached to the sternum. Vertebra —Flat bones that make up the vertebral column.

This large fan-shaped muscle stretches from the armpit up to the collarbone and down across the lower chest region on both sides of the chest. The two sides connect at the sternum, or breastbone.
Is the thorax the rib cage?
rib cage, in vertebrate anatomy, basketlike skeletal structure that forms the chest, or thorax, and is made up of the ribs and their corresponding attachments to the sternum (breastbone) and the vertebral column.
What is the shape of the thorax?
The skeleton of the thorax or chest (Figs. 112, 113, 114) is an osseo-cartilaginous cage, containing and protecting the principal organs of respiration and circulation. It is conical in shape, being narrow above and broad below, flattened from before backward, and longer behind than in front.
What is the other name for trachea?
The trachea, commonly called the windpipe, is the main airway to the lungs.
What type of bone is thorax?

Which is longest bone in our body?
Background. The femur is one of the most researched bones in the human anatomy and forensic medicine. As the longest bone in the human body, it is well preserved in skeletal remains.
Are there 206 or 213 bones in the human body?
There are typically around 270 bones in human infants, which fuse to become 206 to 213 bones in the human adult. The reason for the variability in the number of bones is because some humans may have a varying number of ribs, vertebrae, and digits.

Eupnea is normal breathing at rest.
What is dyspnea caused by?
According to Dr. Steven Wahls, the most common causes of dyspnea are asthma, heart failure, chronic obstructive pulmonary disease (COPD), interstitial lung disease, pneumonia, and psychogenic problems that are usually linked to anxiety. If shortness of breath starts suddenly, it is called an acute case of dyspnea.
How is breathing controlled?
Breathing is usually automatic, controlled subconsciously by the respiratory center at the base of the brain. Breathing continues during sleep and usually even when a person is unconscious. People can also control their breathing when they wish, for example during speech, singing, or voluntary breath holding.
What ribs protect the heart?
Together with the anterior ribs, the sternum helps to protect the heart and lungs from damage, as well as facilitates the expansion and contraction of the thoracic cavity during respiration.
Why thoracic organs are separated?
The thoracic wall actually encloses a cavity, or space, that is filled with various anatomical structures. Since there are so many of them, the thoracic cavity is divided into several compartments to aid their localization.
What is inside the chest cavity?
The chest cavity is the area surrounded by the thoracic vertebrae, the ribs, the sternum, and the diaphragm. … The mediastinum is in the center of the chest and contains the heart, thymus, and lymph nodes, along with portions of the aorta, vena cava, trachea, esophagus, and various nerves.
What is HRCT chest?
