Connective Tissue
the stroma is a bed of elastic connective tissue
The stroma
A stroma is the connective, part of a cell, organ or tissue. The function of a stroma is to hold the cell, organ, or tissue together and help it maintain form.
It is the tissue which surrounds and supports the actually functional lung tissue
Reticular connective tissue
Lungs are made of spongey elastic tissue. Muscles around the lungs help it contract.
The stroma of organs such as the liver and spleen is formed by connective tissue. This tissue provides structural support and helps maintain the shape and function of the organs. It also contains blood vessels, immune cells, and other support structures.
Blood is called specialized fluid connective tissue because of its composition of blood cells suspended in the blood plasma.
Stroma is the medical term meaning the connective tissue that provides the framework for an organ. It's counterpart is parenchyma, which means the main mass of the organ.
Areolar tissue in the lungs forms part of the lamina propria, an underlayer of the serous membranes (pleura) of the lungs.
The stroma is the fluid-filled space surrounding the grana inside chloroplasts. It plays a role in the synthesis of organic molecules through the Calvin cycle, which is a series of reactions that convert carbon dioxide into glucose using energy from sunlight. Additionally, the stroma contains enzymes, DNA, and ribosomes necessary for protein synthesis within the chloroplast.
1. Muscle 2. connective tissues expand and contract the lungs. 3. Nervous tissue sends and receives messages that help regulate gas exchange in the lungs and the rate at which a person breathes. 4. Epithelial tissue forms the inner lining of the lungs.
