2025年2月11日 · In the thorax, the trachea ends where it splits into the left and right bronchi, which continue onward toward the lungs. Viewed in cross section, the trachea is about one inch (2.6 cm) in diameter. It has a thin, membranous wall …

2024年3月27日 · The trachea, known colloquially as the windpipe, connects the upper respiratory tract to the lungs via the tracheobronchial tree, enabling gas exchange. The trachea is a tube-shaped structure consisting of 15-20 D-shaped cartilage rings anterolaterally bridged by …

2017年3月15日 · Trachea is the medical name for the windpipe, the largest airway in the respiratory system, about 4-5 inches in length and 1 inch in diameter that extends from the lower end of the larynx or voice box [1]. An integral part of the human airway, the trachea, bronchi, bronchioles, and alveoli together make up the lower respiratory tract [2, 3].

(c) Cross section of the trachea showing the C-shaped tracheal cartilage. The larynx (Figure 2 and 4) and the trachea are anterior to the digestive tract (esophagus) in the neck and can be accessed directly when upper parts of the airway system are blocked.

2023年9月19日 · The trachea, or windpipe, is a 9-15 cm long fibrocartilaginous tube of the lower respiratory tract. It forms the trunk of the tracheobronchial tree, or pulmonary conducting zone. The trachea extends between the larynx and thorax, consisting of two parts; cervical and thoracic.

The trachea is a tube that connects the larynx to the lungs allowing the passage of air. It is a fibromuscular tube supported by 15 to 20 "C"-shaped hyaline cartilages. Cross-Section - partial cross-section of a single, hyaline cartilage ring.

To design a large-volume, low-pressure cuff it is essential to take into consideration cross-sectional shape and circumference of human trachea. Two hundred adult tracheas were dissected and autopsy specimens examined. Cross-sectional tracheal shapes were studied and their circumference measured.

2024年10月15日 · Cross-section of the trachea showing the following layers of tracheal wall beginning from the tracheal lumen: lamina propria (lp), submucosa (sm), salivary glands (sl), cartilage of tracheal ring (trc), and investing adventitia (ta), muscle (∗).

How does the tracheal epithelium protect against pathogens and debris? What types of glands are present in the tracheal submucosa and their function? How does the histology of the trachea change during coughing or forced expiration?

Tracheal Cartilage - cross-section of a single, "C"-shaped hyaline cartilage that is open in its posterior aspect. Trachealis Muscle - smooth muscle that spans the ends of tracheal cartilages. They control the diameter of the trachea.
