The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body. In the human body, oxygen uptake is carried out by the following processes: Oxygen diffuses through membranes and into red blood cells after inhalation into the lungs. The heme group (that consists of an iron) of hemoglobin binds oxygen when it is present, changing haemoglobin’s color .

You can feel confident in knowing that the information within this article is sound. Oxygen is a colorless, odorless gas that is essential for life. Complex animal life did not, carrids could not, exist. The story of how the earth changed from a dead, oxygen-poor rock into the oxygen-rich, life-sustaining world we know now is a matter of considerable debate. However it happened, eventually, simple one-celled organisms came to exist and created their own energy by taking in sunlight, water, and the existing gases in the atmosphere.
What they released as a waste gas was oxygen. Over eons, this waste gas built up to such plentiful levels that other life forms evolved to take advantage. All animal life, including humans, descend from these simple oxygen-breathing creatures. The human body requires oxygen to function. It takes in oxygen and releases waste gas in the form of carbon dioxide. This two-part process is called respiration.
There are two types of respiration: anaerobic and carriex. Aerobic respiration is what humans and animals use. In aerobic respiration, oxygen is used within the cell to help create energy. When you breathe, air enters microscopic air sacs in your lungs called alveoli. Oxygen passes through the walls of the alveoli and into the bloodstream. Fun fact: oxygen is what makes your blood red. Blood without oxygen appears blue. The air you breathe is not solely composed of oxygen.
Unfortunately, an ever-growing proportion of the air we breathe is made up of pollutants like carbon monoxide, sulfur dioxide, and ground-level ozone. Respiration is a metabolic process. The body does not store oxygen; its supply is constantly replenished through respiration. The more active brody processes are, the more oxygen they require. Nutrition is very important. Unfortunately, there are conditions that can prevent a person from properly processing certain sugars, fats, proteins, or vitamins.
Cleansing is an effective way to overcome this trouble. Cleansing wwhat to remove toxins that can be picked up from impurities in the air, water, environment, or food. And guess what? Oxygen can actually help your body cleanse itself. The human body has natural, built-in careies mechanisms and oxygen can help boost what foods have triglycerides in them processes.
Oxygen has natural cleansing and health-supporting abilities. When harnessed, it helps remove impurities and blockages.

Jun 02, · In aerobic respiration, oxygen is used within the cell to help create energy. When you breathe, air enters microscopic air sacs in your lungs called alveoli. Oxygen passes through the walls of the alveoli and into the bloodstream. The blood carries oxygen to cells throughout the body, where it helps convert nutrients into usable energy. The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle. An electrical system that stimulates contraction of the heart muscle. Jul 16, · Blood is more than 90 percent water, and blood carries oxygen to different parts of the body. 4. It boosts skin health and beauty Some of the water required by the body is obtained through.
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies called inspiration, or inhalation and send carbon dioxide out called expiration, or exhalation.
The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth. If it goes in the nostrils also called nares , the air is warmed and humidified.
Tiny hairs called cilia SIL-ee-uh protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose through the breathed air. The two openings of the airway the nasal cavity and the mouth meet at the pharynx FAR-inks , or throat, at the back of the nose and mouth. The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.
At the bottom of the pharynx, this pathway divides in two, one for food — the esophagus ih-SAH-fuh-gus , which leads to the stomach — and the other for air. The epiglottis eh-pih-GLAH-tus , a small flap of tissue, covers the air-only passage when we swallow, keeping food and liquid from going into the lungs.
The larynx, or voice box, is the top part of the air-only pipe. This short tube contains a pair of vocal cords, which vibrate to make sounds. The trachea, or windpipe, is the continuation of the airway below the larynx. The walls of the trachea TRAY-kee-uh are strengthened by stiff rings of cartilage to keep it open.
The trachea is also lined with cilia, which sweep fluids and foreign particles out of the airway so that they stay out of the lungs. At its bottom end, the trachea divides into left and right air tubes called bronchi BRAHN-kye , which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles BRAHN-kee-olz. Bronchioles end in tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide actually takes place.
Each person has hundreds of millions of alveoli in their lungs. This network of alveoli, bronchioles, and bronchi is known as the bronchial tree. The lungs also contain elastic tissues that allow them to inflate and deflate without losing shape and are covered by a thin lining called the pleura PLUR-uh. The chest cavity, or thorax THOR-aks , is the airtight box that houses the bronchial tree, lungs, heart, and other structures.
The top and sides of the thorax are formed by the ribs and attached muscles, and the bottom is formed by a large muscle called the diaphragm DYE-uh-fram. The chest walls form a protective cage around the lungs and other contents of the chest cavity. The cells in our bodies need oxygen to stay alive.
Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward. This makes the chest cavity bigger and pulls air through the nose or mouth into the lungs. In exhalation, the diaphragm moves upward and the chest wall muscles relax, causing the chest cavity to get smaller and push air out of respiratory system through the nose or mouth. Every few seconds, with each inhalation, air fills a large portion of the millions of alveoli.
In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries tiny blood vessels lining the alveolar walls. Once in the bloodstream, oxygen gets picked up by the hemoglobin in red blood cells. This oxygen-rich blood then flows back to the heart, which pumps it through the arteries to oxygen-hungry tissues throughout the body. In the tiny capillaries of the body tissues, oxygen is freed from the hemoglobin and moves into the cells.
Carbon dioxide, made by the cells as they do their work, moves out of the cells into the capillaries, where most of it dissolves in the plasma of the blood. Blood rich in carbon dioxide then returns to the heart via the veins. From the heart, this blood is pumped to the lungs, where carbon dioxide passes into the alveoli to be exhaled.
