What cell organelle is compared to the respiratory system?

What cell organelle is compared to the respiratory system?

Encyclopædia Britannica, Inc. The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).

What cell makes the lungs?

alveolar epithelial cells
To stay healthy, our lungs have to maintain two key populations of cells: the alveolar epithelial cells, which make up the little sacs where gas exchange takes place, and bronchiolar epithelial cells, also known as airway cells, which are lined with smooth muscle.

What body process takes place in the ability of the lungs?

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

What is the cell line of human embryonic lung?

Name the cell line of the human embryonic lung? Explanation: MRC-5 is the cell line of the human embryonic lung while HeLa is the cell line of human cervical carcinoma.

What is a group of cells with similar structure and function?

Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues.

What is the function of the mitochondria in the lung tissue?

Mitochondria as regulators of cellular homeostasis in the lung. Mitochondria are important for the correct functioning of a number of well characterised and specialised lung cells. Mitochondria regulate mucociliary function, mucus secretion and senescence in airway epithelial cells.

What are the lungs like?

The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.

How do cells in the lungs communicate?

Cells communicate with each other by sending messages through a range of signaling pathways. Together these cells work as a barrier to protect the lung from environmental particles that may be breathed in. Additionally, the lung also has multipotent progenitor cells, which can become any of the other types.

What is cell confluency?

Confluency is the percentage area covered by adherent cells. This measurement is routinely used to monitor cell growth and expansion during cell culture experiments. It is key in determining the optimal timings for cell harvest, passage and process interventions such as drug treatment or cell differentiation.

What is epithelial like cells?

Epithelial-like cells are polygonal in shape with more regular dimensions, and grow attached to a substrate in discrete patches. Lymphoblast-like cells are spherical in shape and usually grown in suspension without attaching to a surface.
