To review:
Match the term nasopharynx with the most closely related description given below:
Superior portion of the pharynx
Bridge of the nose
Nose, nasal cavity, paranasal sinuses, nasal conchae, and nasopharynx
Windpipe
Lobar bronchi
Contains and protects the glottis
Larynx, trachea, bronchi, bronchioles, and alveoli of the lungs
Provide protection for the vocal folds
Positions and stabilizes the larynx
Segmental bronchi
Introduction:
Nasopharynx is the upper region of the pharynx that connects with the posterior portion of nasal cavity present above the soft palate. The soft palate is present in between the oral cavity and nasopharynx. The human respiratory system is segregated into parts namely upper and lower respiratory system. The organs present in both the systems are different and perform a specific function that is important for the respiration of the organism.

- John, a healthy twenty-eight year old electrical engineer, was driving home from work one evening when he experienced sudden stabbing pain in his right pectoral and right lateral axillary regions. He began to feel out of breath and both his respiratory rate and heart rate increased dramatically. As luck would have it, John passed a hospital each day on his way home and was able to get himself to the hospital’s emergency room. The emergency room physician listened to John’s breathing with a stethoscope and requested blood gas analysis and a chest x-ray. John answered a few of the doctor’s questions. The doctor noted that John had no history of respiratory problems but was a heavy smoker. After viewing the chest radiograph, the doctor informed John that he had experienced a spontaneous pneumothorax, or what is commonly called a collapsed lung. The doctor explained that a hole had opened in John’s right lung and that this hole had allowed air to leak into the cavity surrounding the lung.…arrow_forwardIndicate whether the view shows inhalation or exhalation. a .................. b..................arrow_forward(a) Describe the steps of erythrocyte formation in the bone marrow.(b) What name is given to the immature type of red blood cell that is newly released into the circulation?arrow_forward
