The mammalian trachea and esophagus both connect to the
- A. large intestine.
- B. stomach.
- C. pharynx.
- D. rectum.
Introduction:
The human respiratory system consists of several parts starting from the nose to the lungs. All organs have different functions; for example, nostrils are involved in the inhalation and exhalation of air. The pharynx passes air to the lungs. In this way, all organs have different functions in the body.
Answer to Problem 1TYU
Correct answer:
The structure that is connected to the mammalian trachea and the esophagus is pharynx. Therefore, option (C) is correct.
Explanation of Solution
Reason for the correct statement:
The trachea is also known as the windpipe. It is a cartilaginous structure. The pharynx is located behind the nasal cavity and the mouth, and above the esophagus. It is divided into three sections, namely nasopharynx, oropharynx, and laryngopharynx. It is connected to the trachea and the esophagus.
Option (C) is given as “pharynx”.
“In mammals, both trachea and esophagus are connected to the pharynx. The pharynx is found in both vertebrates and the invertebrates, but its anatomy varies from one organism to another. Thus, it is the right answer.
Hence, option (C) is correct.
Reason for the incorrect statements:
Option (A) is given as “large intestine”.
The large intestine is not connected to the trachea and the esophagus. Therefore, it is a wrong answer.
Option (B) is given as “stomach”.
The function of the stomach is food digestion, and it is not connected to the esophagus and the trachea. Therefore, it is a wrong answer.
Option (D) is given as “rectum”.
It is the last part of the human digestive tract and the function of the rectum is to excrete waste from the body. It is not connected to the esophagus and the trachea. Therefore, it is a wrong answer.
Hence, options (A), (B) and (D) are incorrect.
The pharynx is connected to the trachea and the esophagus. In mammals, it is an important part of the respiratory system.
