What else can I help you with?
Alveoli have neither smooth muscle or mucous secreting cells?
That is correct. Alveoli only contain only two types of cells: Type I cells that are like thin sheets and make up the actually wall of the alveoli, and Type II cells that secrete a substance called surfactant that helps to hold the alveoli open. There can also be some macrophages present in the alveoli to destroy invading bacteria.
When oxygen is being carried back to blood cells?
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
What is the function of type 2 alveoli walls?
Type 2 alveoli cells secrete surfactant, which helps to reduce surface tension in the alveoli. This allows for easier expansion of the alveoli during inhalation and prevents them from collapsing during exhalation, promoting efficient gas exchange.
How do human cells get rid of waste?
By the lungs and alveoli.
Is the alveoli comprised of millions of cells?
No, alveoli consist of flattened epithelial cells which make the diffusion rate faster (by the reducing the distance the path that oxygen has to diffuse through).
How does oxygen from the alveoli reaches the heart?
From the Alveoli, it transfers to red blood cells, which travels through the circulation and reaches the heart.
Where does the air meet the red blood cells at?
Its in alveoli of lungs
What cells make your Respiratory system healthy for humans?
alveoli
Do cells of alveoli or lungs also require oxygen to carry cellular respiration?
Yes, the cells of the alveoli and lungs require oxygen to carry out cellular respiration. Although the primary function of alveoli is gas exchange, the cells that make up the alveoli and surrounding lung tissue rely on oxygen to produce energy through aerobic respiration. This process is essential for maintaining cellular functions and overall lung health.
What do the alveoli and blood capillaries have in common and why?
thay are both thick cells :)
What cells secrete surfactant that reduces the tendency for pulmonary alveoli to collapse?
Type II alveolar cells in the lungs secrete surfactant, which is a specialized fluid that lowers surface tension in the alveoli. This reduces the tendency for the alveoli to collapse during exhalation and helps maintain the elasticity of the lungs for efficient gas exchange.
Is a alveoli cell a plant or animal cell?
Neither, alveoli are the air sacs within the lungs in mammals (singular alveolus).
