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.

- You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forwardUse the following tree diagram to answer Questions #8-10. 8) Which of the following two animals are the most closely related based on the tree to the left? a) Pig and camel b) Hippo and pig c) Deer and cow 9) CIRCLE on the tree diagram where the common ancestor between a hippo and a cow is. 10) Put a SQUARE on the tree diagram where the common ancestor between a pig and a peccary is.arrow_forwardExplain: Healthy Cell Function Overview→ Briefly describe how a healthy cell usually works: metabolism (ATP production), pH balance, glycogen storage, ion transport, enzymes, etc. Gene Mutation and Genetics Part→ Focus on the autosomal recessive mutation and explain: How gene mutation affects the cell.
