Let's simply learn about the 'tissues' that make up our bodies? (Body Tissue)

Have you ever wondered what our bodies are really made of? We are not made of one big thing. Just like a big building is made of small bricks, our bodies are made of small parts. We call these parts 'cells'. So, when many of these cells that work the same way come together, we call them 'tissues'. This is what we are talking about today.

What is this 'organization' inside the body?

The easiest way to understand this is to think of our body as a big company. Look at how beautifully organized this organization is, from top to bottom:

• Your entire body: This is the entire company. For it to work properly, every department and every employee has to work together.
• Organ systems: These are like the big departments in a company. For example, things like the digestive system, the respiratory system, etc. All of these departments work together to do a big, complex job.
• Organs: These are like separate factories within those departments. Think of things like the heart, lungs, liver, and kidneys. Each of these organs is made up of at least two types of tissue.
• Tissues: These are like 'groups' of specialized work inside a factory. These tissues are formed by the joining together of many cells that do the same job. This is what we're talking about today.
• Cells: These are the individual employees of the company. There are over 200 different types of cells in our bodies. Each cell has a specific job.

Do you understand how organized our bodies are now? Only when all these levels are working properly can we stay healthy.

What are the main types of body tissues?

The tissues in our bodies can be divided into four main types. Each type has a specific function. These are like teams of specialists in different departments.

Now let's talk about each of these types in a little more detail.

1. Epithelial Tissue - Our Protector

This type of tissue is present in our bodies as a covering . Think of the outermost layer of your skin (epidermis) or the membrane that covers the cornea of ​​your eye . These protect the delicate parts inside from the outside world.

Also, the walls of the organs inside our body are covered with this epithelial tissue. For example, the inner wall of the stomach. These act like gates, that is, they control what things can be taken in and what can be taken out. The cells of this tissue are very neat, very close to each other.

2. Connective Tissue - The 'Gum' That Holds Everything Together

As the name suggests, the main function of this type of tissue is to connect and hold different parts of the body together . Some connective tissues actually help hold our bodies together.

Unlike epithelial tissue, this tissue has large spaces between the cells. This space is filled with a substance called 'matrix'. The proteins and other components in this determine the thickness and strength of the tissue.

3. Muscle Tissue - The engine responsible for our movement

When we talk about muscle tissue, the first thing that comes to mind is movement . This tissue is made up of fibers that are intertwined and joined together. Movement occurs when these fibers join together and contract and stretch. When they join together in this way, they provide greater strength than if they were a single fiber.

There are two types of these movements:

• Internal movements: For example, your heart beats. It pumps blood. Also, when we eat, muscles contract to move food through the digestive tract. We can't control these.
• External movements: Things like moving our arms and legs, walking, and running as we want. We can control these.

Another unique feature of muscle tissue is that it responds to electrical signals . That is, a muscle contracts when it receives an electrical signal. This is essential for every muscle in our body to function.

4. Nervous Tissue - Our Communication Network

Nerve tissue is also made up of fibers. But these don't move like muscle fibers. Instead, they carry electrical and chemical signals throughout the body at very high speeds .

This is like a telephone wire system in our body. Its main function is to carry messages from one place in the body to another. Like muscle tissue, nervous tissue also responds to electrical signals. But the main difference is that nervous tissue carries the signals it receives to their destination in the same way.

When talking about the brain, you may have heard of `(gray matter)` and `(white matter)`. Both of these are nervous tissue. The areas where nerve cells called `(neurons)` are bundled together are seen as `(gray matter)`, and the areas where long fibers called `(axons)` that extend from those neurons are bundled together are seen as `(white matter)`.

What type of tissue is most abundant in our body?

Connective tissue is the most abundant and ubiquitous tissue in our body. The reason for this is that most things belong to this type. Think about it, except for the outermost layer of the skin, all other parts, bones, blood, all of these are connective tissue. Therefore, this is the most abundant type of tissue in our body.

What if a doctor talks about 'tissues'?

Even though we don't usually use the word 'tissue' in our daily lives, it's what we're made of. But imagine, your doctor tells you, "Let's take a tissue sample." Or, "Your disease only affects this type of tissue." At that time, even a common word can feel like a big deal to us, and we can feel scared.

It is very important for you to know about your body and how it works. It will help you make the right decisions about your health .
