Croup
...  the doctor requests for tests to be done such as complete blood count, X-rays and culture of the suspected pathogen as needed. Croup, also known as laryngotracheobronchitis, leads to swelling of the Larynx, trachea and large bronchi. Infection causes the swelling (due to the infiltration of white blood cells). The swelling interferes with normal breathing and causes the characteristic  ...

Mouth
...  not the least is the articulation of the speech, which involves numerous parts of the mouth to work together, namely the tongue, lips, and jaw. These parts of the mouth work with the lungs, Larynx, glottis, and other vocal chords and apparatus that the body has. These three processes, when put together, are what we then call the miracle of our human speech. The most fascinating part is  ...

Lungs
...  chest cavity, air from the lungs then travels out of the airways. This cycle is repeated every time you breathe. The air you breathe goes into the trachea and travels down to the vocal cords in the Larynx up to the bronchi. From the bronchi, the air then passes through each lung until it reaches the alveoli. The oxygen concentration in each air sac is high; this causes the oxygen to pass across  ...

Testes
...  growth during male maturation that is responsible for the onset of secondary sex organs such as the prostate and seminal vesicles. Androgens are responsible for stimulating other organs such as the Larynx, which causes a deep voice range in men. It also stimulates the growth of bone which results in thicker bone mass than females as well as higher hemoglobin levels. Androgens stimulate the  ...

Thyroid Gland
...  side of the trachea. A lobe measures 2 inches in length, connected by a stub of tissue known as the isthmus. The thyroid is the biggest of all the endocrine glands, specifically found beneath the Larynx. This organ’s high denmand for vascular support is satisfied by the two branches of the external carotid arteries, and the inferior thyroid branches of the subclavian arteries. Superior  ...
