Ever Wondered How Your Amazing Body Organs Work Together Every Single Day?

Have you ever wondered about the incredible parts hiding inside your body? These parts are known as organs. We often hear about famous organs like your heart, brain, and liver, but there are so many more working hard right now.

Today, let us explore what organs really are, how they function, and why they matter so much to your everyday health. We will chat about this just like good friends sitting down for a friendly conversation.

What Are Organs Exactly?

Simply put, an organ is a specialized structure inside your body that performs a specific job. Think about your heart, your brain, or your liver. These are the organs you hear about most often.

However, many other body parts are also true organs. For instance, did you know your skin is an organ? Many people forget that skin covers the entire body and protects us every day.

To understand this better, let us break down how your body is built. Every single cell in your body acts like a dedicated worker doing a specific task.

Next, cells with the exact same job join together in one area to form groups called tissues. An organ is simply a collection of different tissues working together to complete a much larger, complex job.

Imagine a large company with different departments. Every department works together to make sure the entire business runs smoothly and successfully.

What Are the Main Organ Systems in Our Body?

Organs never work all by themselves. They connect with each other to form large systems. Some organs even belong to more than one system at the same time.

Let us look at the primary organ systems and the specific organs that belong to each one.

• Cardiovascular System: The main organ here is your heart. It also includes large blood vessels like arteries and veins, plus tiny capillaries. This system pumps blood all through your body.
• Digestive System: This includes your stomach and intestines, meaning both your small intestine and large intestine. It also features your esophagus, mouth, and anus. This system breaks down food to give you energy.
• Endocrine System: This includes glands like your pancreas, thyroid gland, and adrenal glands. These glands produce hormones that control many activities across your body.
• Immune System: This system includes your spleen and bone marrow. Bone marrow creates various blood cells, especially special immune cells that protect you from infections.
• Musculoskeletal System: This includes all your muscles and bones in your skeleton. It also features connective tissues like ligaments and tendons that help you move.
• Nervous System: The primary organs here are your brain and spinal cord. It also includes nerves throughout your body and sensory organs like your eyes, ears, and nose.
• Reproductive System: This includes female organs like ovaries, the vagina, and uterus, plus male organs like the penis, prostate, and testicles.
• Respiratory System: This includes openings like your nose and mouth, plus internal organs like your lungs. This system allows you to breathe fresh air.
• Urinary System: This includes internal organs like your kidneys and bladder. It helps filter waste products and removes them through urine.

Some organs exist as single structures, like your heart. Other times, multiple similar structures make up an organ, such as your bones. Bone marrow inside many bones is also considered an organ.

How Many Organs Are in Our Body?

The answer to this question depends on who you ask. Before the year 2016, medical science generally accepted that the human body had 78 distinct organs.

However, modern medical research has updated this number. If you ask a medical expert today, they will likely tell you the number ranges between 78 and 80.

Two major research papers published in 2016 and 2018 caused this exciting shift in medical textbooks. Let us look at these newly recognized structures:

• The Mesentery: This is a fold of membrane that attaches your intestines to the abdominal wall. It supports digestion and connects with your immune and lymphatic systems. Famous medical books now officially classify the mesentery as an organ.
• The Interstitium: This is a fluid-filled space network found between tissues throughout the body. It surrounds major organs and acts as a shock absorber.

Scientists continue to study how these newly recognized structures function. Future medical discoveries may reveal even more fascinating details about our anatomy.

What Are Vital Organs That We Cannot Live Without?

Vital organs are the absolute essentials required for human survival. Your body simply cannot function without them operating correctly.

Here are the primary vital organs that keep you alive every single day:

• Brain: Controls thoughts, breathing, heart rate, and every movement you make.
• Heart: Pumps oxygen-rich blood continuously to every tissue in your body.
• Kidneys: Filter waste and extra fluid from your blood to produce urine (you need at least one functioning kidney).
• Lungs: Take in oxygen and release carbon dioxide with every breath (you need at least one functioning lung).
• Liver: Clefilters toxins, processes nutrients, and produces vital proteins.

If even one of these vital organs stops working properly, your entire health is right away at risk. Protecting these organs through healthy habits is essential for a long life.

Are There Organs Located on Only One Side of the Body?

Yes, some organs sit right in the middle of your body. This others clearly lean toward one specific side.

Organs Located in the Center:

• Brain: Centered inside your protective skull.
• Bladder: Located in the lower central pelvis.
• Heart: Sits mostly in the center, though it tilts slightly toward the left side.

Organs Located on the Left Side:

• Pancreas: Extends across the upper left abdomen.
• Stomach: Sits tucked under the left side of your ribcage.
• Spleen: Located high up on the upper left side of your belly.

Organs Located on the Right Side:

• Appendix: Attached to the large intestine in the lower right abdomen.
• Gallbladder: Sits snugly right beneath your liver on the right side.
• Occupies a large space under your upper right ribs.

We also have many paired organs that appear on both sides of the body, such as lungs, kidneys, eyes, ears, and reproductive organs.

What Organs Can We Live Without?

It might surprise you to learn that humans can survive without several non-essential organs. Examples include:

• Appendix: A small pouch that is not necessary for digestion.
• Gallbladder: Helps store bile, but your liver can send bile directly to your gut instead.
• Ovary or Uterus: Reproductive organs that can be surgically removed if needed.
• Spleen: Can be removed if injured, though other organs take over some immune functions.
• Testicles: Can be removed for medical reasons.
• Large Portions of the Bowel: Can be removed due to disease.

also, you can live a full life with just one paired organ, such as having a single lung or a single kidney.

However, you cannot live without your heart or brain. Modern medicine has created artificial alternatives like artificial hearts and dialysis machines to support failing organs temporarily or while waiting for a transplant.

What Are Accessory Organs?

Accessory organs are organs that help a body system function, even if they are not the primary part of that system. For example, your gallbladder is an accessory organ in the digestive system.

Another example is your breasts, which support the reproductive system by producing milk during motherhood.

Calling an organ an accessory does not mean it is unimportant. Your liver is technically an accessory digestive organ, yet you cannot survive without it.

What Is the Largest Organ in Our Body?

The largest organ in your body by far is your skin. It accounts for about 15 percent of your total body weight!

When looking strictly inside your body at internal organs, the liver takes the crown as the largest internal organ.

Organs are not just hidden inside you. External structures like your eyes and facial features are also vital organs. When everything works smoothly, you rarely notice them. But if an illness strikes one organ, it affects your entire wellbeing.
