Human anatomy helps us understand the function and importance of complex structures within our bodies. Explore how different systems look and work.

The trachea, bronchi, and bronchioles are known as the bronchial tree because it looks like an upside-down tree. The trachea is the trunk, the bronchi are the limbs, the bronchioles are the branches, and the alveoli are the leaves. Carina The bronchi begin at the bottom of the trachea...
Various parts of the brain signal the nervous systems and organs to prepare to take action. 多个大脑部位传送出采取措施的信号给神经系统和各个器官: The pupils of the eyes dilate, the thyroid gland raises the resting metabolic rate. 瞳孔放大,甲状腺加快新陈代谢, The bronchioles in the lungs dil...
The structures of the lower respiratory system include the trachea, through the lungs and diaphragm. These structures are responsible for gas exchange and external respiration.

The lower respiratory tract is comprised of the conducting (non-respiratory) tracheobronchial regions (trachea, bronchi, and conducting bronchioles including the terminal bronchioles), and the distal respiratory airways (respiratory bronchioles, alveolar ducts, and alveolar sacs or alveoli), where gas ...
The lower respiratory system, or lower respiratory tract, consists of the trachea, the bronchi and bronchioles, and the alveoli, which make up the lungs. These structures pull in air from the upper respiratory system, absorb the oxygen, and release carbon dioxide in exchange. Other structures, ...
Air enters and leaves the lungs via a network of passageways consisting of the trachea, bronchi, bronchioles, and alveoli. Several structures enter each lung via a hilum: principal bronchus, pulmonary artery, two pulmonary veins, bronchial vessels, pulmonary autonomic plexus, lymph nodes and ...
thebronchioles. The terminal bronchioles formed in this tree-like network end in cul-de-sacs called thealveoli. These structures are surrounded by capillary networks and are the site of gas exchange in the respiratory system. Human lungs contain on the order of 400,000,000 alveoli. The outer ...
