Which Organ Removes Carbon Dioxide From the Body?

The lungs and respiratory system allow oxygen in the air to be taken into your body, while also letting the body get rid of carbon dioxide in the air breathed out.

In the lungs, oxygen and carbon dioxide exchange takes place in millions of tiny air sacs called alveoli and the blood capillaries that surround them. These processes are essential for respiration.

The Lungs

The lungs are two air-filled organs located on each side of the chest (thorax) of Helium gas. They take in oxygen from the air and remove carbon dioxide from the blood.

The lung's ability to perform this function depends on the number and size of the alveoli, bronchioles, and capillaries within them. It also depends on the physical properties of these organs, including elasticity and surface tension.

Each lung is made up of two main lobes. These lobes contain airways that connect to the trachea (windpipe). The windpipe is connected to the lungs through tubular tubes called bronchi.

Bronchi branch into smaller, even smaller tubes called bronchioles, which end in tiny air sacs or alveoli where oxygen and carbon dioxide exchange occurs. Each person has hundreds of millions of these tiny sacs in their lungs.

The alveoli are surrounded by a thin wall for Acetylene Gas of cells called the interstitium, which contains blood vessels and cells that help support the alveoli. In addition, the alveoli are lined with a substance that acts like a filter to catch dust and other particles in the air.

These filters work with the cilia to clean the lungs of the dust and other particles in the air, so that the lungs are able to take in more oxygen and remove more carbon dioxide. The cilia are also responsible for carrying mucus from the air to the throat where it can be coughed up or swallowed.

In a healthy adult, the lungs can inhale and exhale up to about 100 litres of air per minute. This can vary depending on the age, activity level and other factors.

You breathe in and out of your lungs around 12-20 times a minute if you're resting. This can be a lot faster if you're exercising or performing other activities.

The bronchi and bronchioles in your lungs are the main ways your body receives oxygen from the air. These airways also carry deoxygenated blood from the pulmonary circulation to your lungs and back again, where red blood cells pick up oxygen and transport it to tissues throughout the body.

The Heart

Your heart is a muscular organ that works around the clock to pump blood throughout your body. It pumps about 8 pints of blood a day, delivering oxygen-rich blood to tissues and organs and carrying away waste.

Your body is made up of a complex system of blood vessels that carry oxygenated and deoxygenated blood to and from the organs. This circulatory system is designed to deliver oxygen and nutrients to the cells, while removing metabolic waste products like carbon dioxide.

The organs that remove carbon dioxide are the lungs and the heart. Your heart is a four-chambered double pump that supplies your lungs with oxygen and then circulates the blood to every part of your body. It’s located between the lungs and slightly to the left of center, behind your breastbone; it rests on your diaphragm, the muscle partition that separates your chest from your abdominal cavity.

Inside your lungs, tiny air sacs called alveoli are only one cell thick and are surrounded by capillaries. Red blood cells in your blood travel to these capillaries and pick up oxygen.

A protein called haemoglobin in the red blood cells then carries the oxygen to other parts of your body where it’s needed. In the meantime, carbon dioxide passes from your blood into these capillaries and out into the air sacs, ready for you to breathe it out when you need to.

In the alveoli, inspired air – which contains nitrogen, oxygen, and other gases – is exchanged for a mixture of carbon dioxide and other substances by a process called pulmonary ventilation (shown in red on the right). This mixture of inspired air and blood, or blood with a small amount of inspired air, is distributed to the entire body via increasingly branched blood vessels.

During this process, the red blood cells that have been supplying your cells with oxygen change from fully oxygenated (purple) to partially deoxygenated, or yellowish, as they move through these capillaries. This process also transfers waste products into your capillary blood to be excreted from your body.

The Blood

The blood is the liquid portion of your body's circulatory system, transporting oxygen and other nutrients to and from cells, and removing waste products. The blood is a complex solution that includes more than 90 percent water, protein, salts and fats, as well as enzymes, antibodies and other substances that are essential to your health.

Blood is made up of red blood cells (erythrocytes), white blood cells, platelets and other cells in a fluid called plasma. The plasma component is about 90 percent water and makes up more than half of the total blood volume. It also contains many other ingredients that help the blood carry out its functions, including clotting factors and immune system components.

Hemoglobin, a protein in red blood cells, is the main ingredient in blood that carries oxygen from the lungs for nitric oxide gas to the tissues of your body and carbon dioxide as a waste product away from the body's cells and back to the lungs. Hemoglobin is brighter when saturated with oxygen and darker when deoxygenated.

In the lungs, blood moves across paper-thin walls of tiny blood vessels (capillaries) into your alveoli, or small air sacs that are the destination for the oxygen that you breathe in. A protein in your red blood cells, haemoglobin, then picks up oxygen from the capillaries and carries it to your bloodstream.

Your lungs also remove carbon dioxide that has been dissolved in your blood and comes out of the capillaries into your alveoli, ready for breathing out. A chemical called carbonic anhydrase helps keep your lungs' pH at a normal level and removes carbon dioxide from your bloodstream when the oxygen-carbon dioxide concentration is high.

Breathing is a voluntary activity and how often you inhale or exhale depends on signals from your brain that tell you when to do so. Your respiratory center in the brain regulates how much oxygen you take in and how much carbon dioxide you exhale.

Your lungs are designed to work in close harmony with your blood system. This relationship is called the "respiratory-circulatory balance."

The Bladder

The organs that remove carbon dioxide from the body include the lungs, the bladder, and the kidneys. The lungs exhale the gas through the airways, the bladder stores urine in the urinary tract until a person urinates (also called “wee”), and the kidneys filter blood to remove waste products from it.

The primary method for removing carbon dioxide is by exhaling it from the lungs, secreting it from the skin, or excreting it in the urine and feces. However, the body also needs to get rid of other wastes. This is done by transferring them from the blood to other organs that can convert waste into other forms of energy, such as fat and protein.

Another way that waste can be removed is by passing it through a tube, called the urethra. The urethra is part of the urinary tract and connects the bladder to other organs in the body.

When a person feels the need to urinate, nerves send signals to the bladder. As a result, the bladder wall contracts, and the urethra tightens, so that urine is prevented from leaking out of the body.

A normal bladder can hold about 400 to 600 mL of urine. It sits in the pelvis, just above and behind the pubic bone for Nitrous Oxide.

The bladder receives urine from the kidneys through two tubes called ureters, entering through openings called ureteric orifices. When the bladder is full, it sends a signal to the brain, which allows the urethra to close off, stopping the flow of urine out of the body.

The bladder is a sac-like structure, about the size of a pear, with muscular walls that can expand to hold more urine as it fills up. It can hold about 1.5 to 2 cups of urine, but a person rarely urinates more than this. The bladder is lined with a thin layer of cells called transitional cells that stretch as the bladder fills and shrink when it empties. It is made up of a mixture of fat, fibrous tissue and blood vessels.
