The wonderful world of our body: Let's learn about organs in a simple way!

Have you ever thought that our body is like an amazing machine that works flawlessly? We breathe, eat, think, run, jump. You must have wondered how all this happens. Behind all this are the amazing parts of our body called organs. Not only the heart, brain, and lungs that we all know, but even our skin, which we don't think about much, is a very important organ. So today, let's talk about what these organs are, how they work, and why we can't live without them.

What is an organ, simply put?

Imagine that our body is a big company. There are employees working in this company, right? That's how the cells in our body are. Each cell has a special job.

Now, when these employees who do the same job come together to form a team, we call them tissues . Just like each department in a company.

Next, we call an organ a unit that is formed by several interconnected tissues that work together to perform a large, specialized function. For example, if we take the heart, its muscle tissue, nerve tissue, and blood vessel tissue all work together to pump blood.

So, simply put, an organ is a collection of tissues that work together to perform a specific function.

What are Organ Systems?

No single organ in our body can do everything on its own. Just as no single department in a company can run the entire company on its own, so organs that work together form organ systems . Let's look at some of the major systems and the organs that belong to them.

Heart and Blood Vessel System (Cardiovascular System)

This is the transportation system of our body. The heart is the main pump . It pumps blood throughout the body. The arteries and veins are like the main roads. The capillaries are like the small side roads leading to the villages. This system carries oxygen and nutrients throughout the body.

Digestive System

This system helps us digest the food we eat and absorb the nutrients it needs. The main organs are the stomach , small intestine, and large intestine . It also includes the esophagus , mouth, and anus .

Endocrine System

This is a system that sends messages to our body. It is what makes chemical messengers called hormones. The pancreas , thyroid gland, and adrenal glandsHere are some important organs of this system.

Immune System

This is our body's army. This system protects us by fighting germs that cause disease. The spleen and bone marrow are its main parts. The bone marrow is where the immune cells in the blood are made.

Musculoskeletal System

This is what gives our bodies shape and strength, and helps us move. It includes muscles and all the bones in the skeleton . It also includes connective tissue called ligaments that connect bones to each other and tendons that connect muscles to bones.

Nervous System

This is the control center of our body. The brain and spinal cord are the main organs. All the nerves spread throughout the body belong to this system. Even our sensory organs, such as the eyes , ears, and nose, work with this system.

Reproductive System

This system is responsible for the organs needed to reproduce, that is, to produce children. Examples include the ovaries , vagina , and uterus in women, and the penis , prostate, and testicles in men.

Respiratory System

This system helps us breathe, that is, take in oxygen from the air and expel carbon dioxide produced by the body. The nose , mouth, and lungs are the main organs of this system.

Urinary System

This system helps filter waste products from the blood and excrete them as urine. The kidneys and bladder are its main organs.

How many organs are there in our body?

When you ask this question, you may get different answers from different people. Before 2016, it was generally accepted that our bodies had 78 organs. But as science advances, researchers are discovering new things about our bodies.

Therefore, some experts today say that there are 79 or 80 senses. The reason for this is two newly discovered, still somewhat controversial, senses.

1. Mesentery: This is a membrane-like structure that surrounds our intestines. It helps our digestive system by affecting our immune and lymphatic systems. Many people now consider it a separate organ.

2. Interstitium: This is the network of small fluid-filled spaces between our cells. It's like a sponge. It's found throughout the body.

These new organs are still being researched, so this number may change in the future.

What are the vital organs that are essential for life?

There are some organs in our body, without which we cannot live at all. We call these vital organs . Without them, our body cannot function.

Are there any senses we can live without?

Yes, surprisingly, there are several organs that we can live without. Sometimes, when we get sick or have an accident, doctors surgically remove these.

• Appendix
• Gallbladder
• Spleen
• One or both testicles
• Ovaries and/or uterus
• Large parts or all of the colon

Also, we can live without one of the paired organs in our body. For example, we can live with one lung or one kidney.

But remember, you can't live without a heart, but there are artificial hearts. And you can't live without both kidneys, but there is a treatment called dialysis to do the work of the kidneys.

What is the largest organ in the body?

Now, a quick question. What do you think is the largest organ in your body? Most people think it's the liver.

But the real answer is skin . Yes, the skin, which covers our entire body, is our largest organ. It makes up about 15% of our total body weight.

But if you ask about the largest organ in the body, it is the liver .

Sense organs are not just things inside our bodies. Even the parts we see on the outside, like our eyes, ears, and nose, are sense organs. We don't really appreciate them until they're all working properly. But if one of our senses has even the slightest problem, we can't think about anything else.

So if you have any concerns about the health of your organs, or the health of your entire body, don't be afraid to talk to your doctor . He or she can give you the best advice on how to keep your body healthy.
