What is the interstitial fluid?

The interstitial fluid is the fluid that surrounds cells, separate from the blood vessel. It contains water, proteins, electrolytes, salts, acids, hormones, and cell waste materials.

What makes up the extracellular matrix?

The extracellular matrix often contains collagen fibers, elastin fibers, glycoproteins, and proteoglycans.

How do cells within tissues communicate?

Cells communicate through connections between the extracellular matrix components, proteins in the plasma membrane, and the cytoskeleton inside the cells.

What is the function of interstitial fluid?

The interstitial fluid allows for the delivery of nutrients to the cells by receiving nutrients from blood vessels and delivering them to tissue cells.

What is the role of the extracellular matrix?

The extracellular matrix provides structural support and holds tissues together, connecting cells to one another.

Summary

TLDRThe video explains the space between cells, which includes interstitial fluid and the extracellular matrix. Interstitial fluid is a liquid that surrounds cells, containing nutrients, proteins, and waste products. The extracellular matrix is composed of various fibers and molecules providing structural support and enabling communication among cells. This setup allows nutrient delivery and supports tissue integrity.

Takeaways

🧬 Interstitial fluid surrounds cells with water, proteins, and waste.
🔗 The extracellular matrix contains collagen and elastin fibers.
🧫 Tissues are supported by connections between cells and the matrix.
📡 Extracellular components enable cell communication.
💧 Interstitial fluid delivers nutrients from blood to cells.

Timeline

00:00:00 - 00:01:47
The spaces between cells are known as the extracellular matrix and contain interstitial fluid. This matrix is crucial for tissue structure and cell communication. It includes collagen, elastin fibers, and various glycoproteins and proteoglycans. Interstitial fluid, comprised of water, proteins, and other compounds, provides nutrients to cells from blood vessels, playing a key role in maintaining cellular functions.

What is in the spaces between cells?
00:00:02
Well, if we look at a group of cells, we have intracellular, which means
00:00:06
inside of a cell, and extracellular, being the space outside of a cell.
00:00:10
These groups of cells make up a tissue, as they are performing common functions.
00:00:15
Many tissues differ in the types and amount of fluid material between cells.
00:00:19
So, again, here we have a group of cells, along with
00:00:22
a blood vessel. This fluid that surrounds
00:00:24
the cells and is separate from the blood vessel is called interstitial fluid.
00:00:28
This interstitial fluid contains water, proteins, electrolytes,
00:00:33
salts, acids, hormones, and cell waste materials.
00:00:36
There are also other components in this extracellular
00:00:39
space, which together are called the extacellular matrix.
00:00:43
The extracellular matrix often contains
00:00:46
collagen fibers, elastin fibers, glycoproteins,
00:00:49
which are proteins with carbohydrate subunits attached and proteoglycans,
00:00:54
which are made up of complex carbohydrates, proteins and smaller carbohydrates.
00:00:59
The interstitial fluid and extracellular matrix have some important functions.
00:01:04
In some tissues, the components of the extracellular matrix are
00:01:07
connected to proteins embedded in the plasma membrane of cells,
00:01:11
which are connected to components of the cytoskeleton inside of the cell,
00:01:15
holding the tissue together, and providing structural support of the tissue.
00:01:19
These connections also allow the cells to communicate with one another.
00:01:22
Another important function is that the interstitial fluid
00:01:26
allows for the delivery of nutrients to the cells,
00:01:28
as it receives nutrients from blood vessels and delivers them to tissue cells,
00:01:33
so the cells can continue to thrive and do their jobs.
00:01:37
And that be the basics on the extracellular matrix and interstitial fluid.
