what is type 1 alveolar cells?
959806
The wall of alveoli consist of two types pf alveolar epithelial cells.The more numerous type 1 alveolar cells are simple squamous epithelial cells that form a nearly continous lining of the alveolar wall.Type 2 alveolar cells also called septal cells are fewer in number and found between type1 alveolar cells.The thin type1 alveolar cells are the main sites of gas exchange.Type 2 alveolar cells rounded or cuboidal epithelial cells with free surfaces containing microvilli,secrete alveolar fluid which keeps the surface between the cells  and the air moist.\n\nWell,since you didnt asked for more detail, this is the most simple answer that i can gave you.Hope this help ya.

Alveoli - Each bronchiole ends in a tiny air chamber that looks like a bunch of grapes.  Each chamber contains many cup-shaped cavities known as alveoli.  The walls of the alveoli, which are only about one cell thick, are the respiratory surface.  They are thin, moist, and are surrounded by several numbers of capillaries.  The exchange of oxygen and carbon dioxide between blood and air occurs through these walls.  The estimation is that lungs contain about 300 million alveoli. Their total surface area would be about 70 square meters.  That is 40 times the surface area of the skin.  \n\nFUNCTIONThe alveoli allow this gas exchange to occur. Each alveoli has a network of capillaries that carry oxygen-poor red blood cells. The capillaries bring the red blood cells very close to the air space in the alveoli. The air in the alveoli is oxygen rich. Oxygen moves from the alveolar space into the red blood cell by diffusion. This can happen very quickly because the surface are of the alveoli is large and the membranes separating the lungs from the red blood cells are very thin. The rate of oxygen diffusion is dependent on surface area, so gas exchange occurs more quickly with larger surface areas.

Trachea divides into bronchi, Bronchi divides into bronchioles and then inte alveoli. Alveoloi are called the air-sacs and they are involved in the air respiration process.\nSo the smallest branch of bronchi are the alveoli(plural)and alveolus(singular).

The tiniest part of our lung is called alveolus (plural is alveoli). It is like an inflated balloon . The air in side this balloon is the fresh air we have inhaled.\n Now imagine your ten fingers covering an inflated balloon from all the sides. That is how the blood capillaries cover the alveoli . these blood capillaries have extremely thin wall through the oxygen, which is at a higher concentration in the fresh air of the alveoli, diffuses in the blood capillary. It is immediately picked up by the hemoglobin in the Red blood cells forming oxyhemoglobin  . It is the source of oxygen to our body. This is then taken to different parts of the body and given to them.\nAt the same time , CO2 collected from the body parts and brought to the alveoli by those vary capillaries diffuses in to the air of the alveoli because its concentration in the capillaries is greater. \nThe air in the alveoli is now stale air rich in CO2 and poor in O2. It is exhaled out.\nThus , the gaseous exchange can occur only on the surface of the alveoli . Their walls are as thin as the walls of a soap bubble, only that they are not fragile like soap bubble.\nIn the body muscles the gaseous exchange occurs in the same fashion but between the capillaries.

the bone cells mature through the different types of bone cells before becoming osteocytes.  they form their matrix while they are either osteoblasts or osteoclasts (i think osteoblasts).  when they are stuck in the matrix that they formed, they are mature osteocytes.

A lymphocyte is a type of white blood cell.  Maybe that's what he meant?  8100 is quite high if that's what he's referring to, but you also have to look at it in relation to the other types of white blood cells.  For instance, was your absolute neutrophil count in normal range?

pulmonary fibrosis is the gradual scarring of lung tissue.  there are several theories as to what causes the injury from genetic to autoimmune to enviromental factors. Air sacs become slowly replaced by scar tissue eventually affecting air exchange. Research in this area is limited. Pt have different stages of progession of disease

as far as i can recall, cheek cells are squamous epithilial. they are flat and are often "connected" to each other in order to protect the tissue that is underneath it. they serve as some sort of cover for tissues and organs in our body

Red blood cells, for one. G1, I think. I see inter-phase above; sounds right.

The alveoli is crucial in supplying fresh oxgen which would be transported to the heart via the pulmonary vein.\n\nIs this okay?

diffusion or gaseous exchange.\non inhaling, oxygen moves through the layer of mucus lining the alveoli and diffuses thru the alveoli cell through the capillary pores and into the blood cells binding with the haemoglobin. \non exhaling, carbon dioxide moves the opposite way. out of the capillary pores, thru the alveoli wall, thru the mucus into the alveoli

Squamous epithelium provides a good cover protecting your tissues from the outside world (the inside of your mouth is still considered "outside" as far as your body is concerned).\n\nYour cheek cells are not absorbent nor secretory. they just cover. That's why they're flat. They also need to be replaced often, so the flatness helps with the flaking off and dying part of the cycle.
