I am not so sure what are you reffering too: the respiratory system or the trachea alone. But for respiratory system there are two functional parts (1) a conducting system to bring the air in, including the nose, pharynx, larynx, trachea, bronchi and bronchioles; and (2) the respiratory portion, the site of gas exchange, including the respiratory bronchioles, alveolar ducts, alveolar saccules, and alveoli.
Trachea: The trachea connects the larynx and bronchi. It is lined with a mucus membrane with respiratory epithelium and a lamina propria, and a submucosa containing horseshoe shape hyaline cartilages and numerous mucus and mixed glands (Trachea 1). The gap between the ends of the cartilages is bridged by fibroelastic connective tissue and smooth muscle (Trachea 2). To increase expandability, the respiratory epithelium is underlaid with a lamina propria containing a distinct elastic lamina (Trachea 3). The trachea is surrounded by an adventitia which is a connective tissue layer shared with the esophagus (Trachea 4). Hope that answers your questions.
What else can I help you with?
What is the valve between the right ventricle and the pulmonary artery?
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
What valve exits the right ventricle?
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
Why does the pulmonary artery split in two and there are plumonary veins?
The pulmonary artery splits into the left pulmonary artery and right pulmonary artery. The left one goes to the left lung and the right one goes to the right lung to receive oxygen. There are also pulmonary veins. They carry oxygenated blood from the lungs to the heart.
The pulmonary arterie branches from the aorta?
No, the pulmonary artery branches from the right ventricle of the heart, not the aorta. The pulmonary artery carries deoxygenated blood from the right side of the heart to the lungs for oxygenation. The aorta, on the other hand, is the main artery that carries oxygenated blood from the left side of the heart to the rest of the body.
What vessels carry blood from the heart?
The aorta, and the carotid artery branches; the pulmonary artery.
The pulmonary artery passes through the wall of the heart and divides into what?
The main pulmonary artery branches into the left and right pulmonary artery. Actually----The division of the heart is known as SEPTA---but your sorta right>sorry ashboo
Semilunar valve are found at the beginning of what two vessels?
There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.
What body system resembles the branches of a tree?
The pulmonary system resembles the braches of a tree. It's sometimes called the pulmonary tree.
What two structures do the pulmonary arteries lead to?
the two pulmonary arteries lead to hogwarts and narnia.
Where is the pulmonary artery located?
In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wide - approximately 5 cm (2 inches) in length and 3 cm (1.2 inches) in diameter. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding lung.
What is the passageway of blood from the heart to the lungs?
You have pulmonary aorta that arises from the right ventricle. It splits into right and left branches. The branches most probably continue to divide with the bronchi. Ultimately you have the network of the capillaries to cover the alveoli.
What are the two types of circulation of blood in the body?
Pulmonary and systemic
