It is the elasticity that keep alveolus in shape. However if it is deflated , surfactant avoid the alveolus from sticking to each other. Smooth muscle greatly hinder the efficiency of gas exchange as it thicken the diffusion surface.
The alveoli consist of an epithelial layer and extracellular matrix surrounded by capillaries. In some The alveoli consist of an epithelial layer and extracellular matrix surrounded by capillaries. In some alveolar walls there are pores between alveoli called pores of Kohn.
There are three major alveolar cell types in the alveolar wall (pneumocytes):
* Type I (Squamous Alveolar) cells that form the structure of an alveolar wall
* Type II (Great Alveolar) cells that secrete pulmonary surfactant to lower the surface tension of water and allows the membrane to separate, thereby increasing the capability to exchange gases. Surfactant is continuously released by exocytosis. It forms an underlying aqueous protein-containing hypophase and an overlying phospholipid film composed primarily of dipalmitoyl phosphatidylcholine.
* Macrophages that destroy foreign material, such as bacteria.
What else can I help you with?
Does the alveolar duct contain connective tissue?
The alveolar duct primarily consists of smooth muscle and elastin fibers but contains minimal connective tissue. Its structure is designed to facilitate the passage of air to the alveoli, where gas exchange occurs. While there is some connective tissue present to provide support, it is not a major component of the alveolar duct's architecture.
Why doesnt the gas exchange occur in the bronchi?
It is due to the presence of smooth muscle.
What is cardiac muscle and smooth muscle tissue?
The cardiac muscles are present in your heart. The smooth muscle are present in your intestine and other many hollow tubes in your body. Both of them are involuntary type of muscles.
What is the name of the smooth muscle present in skin?
erector pili
Are actin and myosin present in smooth muscle?
Yes, actin and myosin are present in smooth muscle. These proteins are critical for muscle contraction, similar to their role in skeletal and cardiac muscles. However, in smooth muscle, the arrangement of actin and myosin is more disorganized, which allows for a different contraction mechanism appropriate for involuntary movements. This structure enables smooth muscle to contract more slowly and sustain contractions for longer periods.
What is the muscle that is found in the small intestine?
smooth musclesmooth muscle
Is an ulcer a cardiac muscle or a smooth muscle?
Smooth muscle
What type of muscle is in the gallbladder?
Smooth muscle is present in the gallbladder. It helps the gallbladder contract and release bile into the digestive system to aid in the digestion of fats.
Which muscle tissue is involuntary and not striated?
SmoothI'm POSITIVE it's the Skeletal Muscle!
Is voluntary muscle smooth muscle?
yes it is.....
Is muscle cell is smooth when hungry?
No, "smooth" muscle is a type of muscle.
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
