How Much Do You Know About Your Organs?

While each of these systems can vary between males and females, the reproductive system stands out among the rest. The systems are basically opposites in every way, but bringing them together creates life.

Your circulatory system consists of all of the parts of your body that transport blood. The heart pumps blood to the rest of your body. The brain is considered a part of the nervous system, and the stomach and small intestine are both parts of the digestive system.

While your skin is important to you (it basically saves the rest of your body from the elements), it is not considered a vital organ, as you can lose large pieces of it and still have proper body function.

Not only is it impossible to see through heart vessels, but the blood inside of them is opaque, which makes it extra difficult to see the heart in motion. This makes it hard to study the heart to get a greater understanding of how it works.

In case you were wondering, bile is the fluid that helps break down fatty foods in your small intestine. It has a yellowish-green color, and it's pretty gross, but it's a great way to ensure your digestive system is running properly.

Anyone who has ever been to a Dermatologist knows that there are three layers to your skin (which is actually known as the integumentary system). Each of these levels has a different function to protect your other organs from harm.

While organs are made up of a lot of cells, each of these cells has a specific function that is different from other cells in the body. They also reproduce at different rates, making each organ uniquely delicate.

The lungs are spongy. You can remember this by considering the fact that they absorb oxygen, and when they expel carbon dioxide, they constrict (kind of like a sponge getting wrung out).

Your lungs take in oxygen and release carbon dioxide (it's pretty much the opposite of trees). Though few of us pay attention to our breathing until we can't, this is something that happens naturally and doesn't normally take conscious behavior.

Lipase is a substance created by the pancreas. The other answers to this question are all parts of the very intricate organ that is known as your heart. Every part of the heart works to send blood to various parts of your body.

Alveolus sacks are little sacks in your lungs that collect air when you breathe in. This oxygen is transported to your bloodstream through hemoglobin and then circulates through your bloodstream by the heart.

Your heart has two atriums (left and right) and two ventricles (left and right). These chambers receive and pump blood through the body in order to carry oxygen to areas that are far from the lungs.

Anyone who has ever had to pee really, really bad knows that your bladder can only hold so much. On average, it can hold around 2 cups in the day time and twice that at night, which is a lot when you really think about it.

The endocrine system helps release hormones into the circulatory system. The most well-known glands in this system include the thyroid and adrenal glands, which have effects on every part of your body.

Remember that your gall bladder stores bile. Your kidneys are meant to filter the blood (taking out metabolic wastes) and transfer what is left over (urine) to your bladder. Kidney health is incredibly important.

A woman's eggs are actually stored in the ovaries. They then pass through the Fallopian tubes. Though they are essential elements to the female reproductive system, they are not considered organs.

Chemicals and electricity are sent through the body by a complex system made up of neurons, axons, synapses, glia and more.

Though much of your anxiety comes from an overworked or misfiring nervous system, there is no such thing as your anxious system. Other organ systems in your body include the reproductive system and the immune system.

While the liver has many functions, one of its main functions is to filter your blood. This is why your liver is so affected when you drink alcohol. Your blood-alcohol level can completely change the way your liver functions.

The largest part of your brain is the cerebrum. It has two hemispheres that help you control much of your body, including speech, voluntary movement and sensory processing. It also helps you store memory.

Your stomach does a lot for you, but the lining can become weak over time, so it's important to make sure you eat healthily and focus on gut and digestive health to ensure that your stomach stays strong and healthy.

The location of the pancreas is behind the stomach. It is an important part of your digestive system as it regulates blood sugar and creates enzymes to help you digest your food properly.

Managase is not a real thing. However, the pancreas creates lipase, which breaks down fat; protease, which splits up proteins; and amylase, which divides carbs and creates sugars. This gives your body nutrients it needs to function.

Remember that the skin (which is the largest organ you have) is outside of your body. However, the largest internal organ is your liver. It never stops functioning, and it takes care of a lot of things for you, including storing vitamins and filtering your blood.

The large intestine is actually shorter than the small intestine, but it is wider. This intestine extracts water from food that isn't easy to digest, then it helps your body get rid of it completely.

The uterus is where a fetus grows and develops before birth. It can grow roughly to the size of a watermelon, but it generally is around the size of an apple when it begins. It's the body's balloon, and it serves a major purpose in the reproductive system.

Your kidneys do quite a bit of work in a day, so take it easy on them. Make sure you drink plenty of fluids and eat fruits like cranberries to help keep your kidneys strong and functioning properly.

The appendix isn't a necessary organ anymore, and most scientists can't even figure out what it there for. One theory suggests it was meant to store good bacteria that helped your digestive system after an illness.

Contrary to popular belief, the small and large intestines aren't long enough to wrap around the world several times. As a matter of fact, the large intestine is only about 5 feet, whereas the small intestine is approximately 20 feet long.

That's right, much like the Earth, your brain is mostly made up of water. This is why it's so important to stay hydrated. You can actually lose cognitive function and memory if your hydration levels drop by 2%.

If you can believe it, the human brain is made up of approximately 100 billion nerve cells that fire rapidly to help us function throughout the day. These cells cover everything from unconscious acts like breathing to interpreting written words.

Yes, the eye is an organ, and it is considered a part of the nervous system. Remember that the nervous system is how your brain communicates with the rest of your body, and your sight is a major part of that communication.

The spleen does have a purpose for humans. It filters your blood and is a great tool for maintaining your immune system. However, the organ is not considered a vital one and can be removed if it is ruptured or infected.

Three pounds is the average weight of an adult human's brain, while a newborn's brain only weighs three-quarters of a pound.

No one likes to talk about it, but it is one of the most important systems of our body. After we digest our food and all of the nutrients are extracted, we need to expel all of the bad stuff from our body, and that is what you leave in the toilet.

Organs such as the stomach, intestine and heart all have tubes or pouches that help them conduct the work that they were meant for. They fill and extract various substances with the help of muscles.

No, there isn't 50 gallons of blood in your body, but this is a clear example of just how frequently your blood flows to each of your body parts and how fast it moves. The kidneys can go through up to 50 gallons and take out around a half a gallon of waste.

Your heart is in the middle of your chest. Your sternum is one of your strongest bones and it protects your heart from outside forces. This is a great defense mechanism to keep your body safe. Thanks skeletal system!

Of all the blood pumped through your system in a given day, your brain receives 20% of it. That's because your brain requires regeneration quickly and efficiently in order to talk to the rest of your body.
