Question

In the thoracic cavity of man which one is present?
a. Lungs only
b. Lungs and heart
c. Lungs, heart and stomach
d. Heart only

Answer 1

Hint: The chamber present in the chest of the human body and protected by the thoracic wall is called the thoracic cavity. The main function of the thoracic cavity is to give protection and support the vital organs of the human body. The rib cage and layers of membranes surround the thoracic cavity. This will help in protecting the organs from any dangers in the environment.

Complete answer:
In the thoracic cavity of humans, both lungs and heart are present. It is an anatomical air-tight chamber. There are two cavities present in the thoracic chamber, one for housing lungs called the pulmonary cavity and the other for housing the heart called the cardiac cavity. The vertebral column dorsally, sternum ventrally, ribs laterally formed the thoracic cavity.
The diaphragm is present on the lower side of the thoracic cavity which is dome-shaped. The lungs are set anatomically in the thorax and if there is any change in its volume of the thoracic cavity then it will directly reflect in the lung or pulmonary cavity.

> Lungs are present in the thoracic cavity but along with its heart is also present. In the thoracic chamber or cavity, only the lungs are not present that is why option A is the wrong answer.

> Lungs and heart are present in the thoracic cavity but the stomach is not present in the thoracic cavity. The stomach is situated in the upper abdomen of the human body that is why option C is the wrong answer.

> The heart is present in the thoracic cavity but along with lungs are also present. Only the heart is not present in the whole thoracic chamber or cavity that is why option D is the wrong answer.

Hence, the correct answer is option (B).

Note: Thoracic chamber consists of lungs and heart. In the thoracic cavity, the lungs are situated on either side of the mediastinum. The thoracic cavity comes on the second number as the largest hollow space in the human body. The pleural cavity surrounds the lungs in the thoracic cavity which is made up of visceral and parietal pleura.
