Function Of Oxygen In The Human Body – One of the main functions is transportation. such as networks of roads for delivery of vessels and disposal of waste. Oxygen, nutrients and hormones are distributed around the body and carbon dioxide and other waste products are removed.
When we breathe, the millions of air sacs in the lungs are filled with fresh oxygenated air. Oxygen moves first through the very thin walls of the air sacs and then into the lungs through a network of tiny vessels called capillaries.

Function Of Oxygen In The Human Body
Red cells squeeze through narrow capillaries in single file. Hemoglobin molecules in red blood cells carry oxygen. These oxygen-rich cells travel from the lungs in vessels that lead to the left side of the heart. Then the entire body is pumped.
Blood Flow Through The Heart And Lungs
Red cells are good for transporting oxygen. Because they are small and flexible, they fit through narrow vessels, they have a bi-concave shape that increases their surface area to absorb oxygen, they have a thin membrane that allows gases to diffuse easily, and they contain hemoglobin that binds to oxygen.
Millions of iron-containing hemoglobin proteins form the red color. Molecules with more oxygen are bright red in color.
When red blood cells reach tissues that need oxygen, the oxygen is released from hemoglobin and diffuses into the cells where it is used to generate energy.
All the systems in our body rely on oxygen to generate energy. If the oxygen we breathe doesn’t move to our organs and tissues, we can’t perform normal functions like moving our muscles, digesting food, or thinking. It keeps us alive.

At the same time, red blood cells take up waste carbon dioxide that has entered the bloodstream from the cells. Red cells that carry less oxygen are dull red, which is why deoxygenated ones in our veins are darker red than deoxygenated ones.
The red cells travel through the veins back to the right side of the heart. Recirculated from the heart to the lungs, where carbon dioxide is expelled from the air sacs. Air is breathed in, oxygen is taken in and the journey begins again.
Digested nutrients are absorbed through the capillaries in the small intestine. They are then transported to cells around the body where they are needed.
Because vessels near cells are smaller in diameter, they flow more slowly, allowing cells to take in nutrients and exchange waste products.
Circulatory System: Anatomy And Function
The waste products are transported to the organs, which remove them and then remove them from the body. For example, excess water is filtered by the kidneys and toxins are removed by the liver.
The movement of hormones in the body allows communication between organs. Hormones help control many processes in our body, including growth, development, mood, metabolism, reproduction, and how our organs work.
Hormones are secreted from glands and then transported to their target organs where they exert their effects. They carry instructions to cells throughout the body. Once hormones reach the target cell they bind to receptors inside or outside the cell.
By traveling in, hormones can affect tissues and organs far away from where they are produced, or have effects throughout the body.
Lungs Information And Facts
There are 60,000 miles of vessels in the body. That’s enough to go around the Earth more than twice.
It takes less than a minute for a red cell to travel from the heart, through the body, and back to the heart.

How Your Body Systems Are Connected
The trachea transports air from the mouth and nose to the lungs, where oxygen and carbon dioxide are exchanged between the alveoli and capillaries.
The human gas exchange organ, the lungs, is located in the chest, where its soft tissues are protected by the bony and muscular thoracic cage. The lungs provide a continuous flow of oxygen to the tissues of the human body and clean the blood of carbon dioxide, a gaseous waste product. Atmospheric air is constantly pumped in and out through a system of tubes that conduct the airways, which connect the gas exchange area with the outside of the body. The airways can be divided into the upper and lower airway systems. The transition between the two systems is located at the top of the larynx, where the trachea and digestive systems cross.
The upper respiratory system includes the nose and paranasal cavities (or sinuses), the larynx (or throat), and partially the oral cavity because it can be used for breathing. The lower respiratory system consists of the larynx, trachea, trunk bronchus, and all airways that extend actively into the lungs, namely the intrapulmonary bronchi, bronchioles, and alveolar ducts. For respiration, the cooperation of other organ systems is clearly necessary. The diaphragm, as the main respiratory muscle, and the intercostal muscles of the chest wall, under the control of the central nervous system, play an important role by creating a pumping action in the lungs. The muscles expand and contract the inner space of the chest, the bony structure of which is formed by the ribs and thoracic vertebrae. The contribution of the lungs and chest wall (ribs and muscles) to respiration is described below in the mechanics of respiration. Blood acts as a carrier for gases and the circulatory system (i.e. heart and blood vessels) is an essential component of the respiratory system (
The nose is the external protrusion of an internal space, the nasal cavity. It is separated into left and right nasal passages by a thin medial cartilage and bony wall, the nasal septum. Each canal opens into the face by a nostril and into the larynx by a sinus. The floor of the nasal cavity is formed by the palate, which also forms the roof of the oral cavity. The complex shape of the nasal cavity is caused by projections of the bony ridges, upper, middle and lower turbinate bones (or conchae) from the lateral wall. Thus the passages that form below each ridge are called the superior, middle and inferior nasal meatus.
Circulatory System: Pulmonary And Systemic Circuits
On each side, the intranasal space continues with the neighboring air-filled cavities in the skull (paranasal sinuses), and through the nasolacrimal duct, communicates with the lacrimal apparatus at the corner of the eye. The duct drains the lacrimal fluid into the nasal cavity. This fact explains why nasal breathing can be quickly affected or obstructed during crying: tear fluid not only overflows with tears, but also floods the nasal cavity.
The paranasal sinuses are single or multiple pairs of sinuses of varying size. Most of their growth takes place after birth, and they reach their final size by age 20. The sinuses are located in four different skull bones—the maxilla, frontal, ethmoid, and sphenoid bones. Accordingly, they are called the maxillary sinus, which is the largest cavity; frontal sinus; ethmoid sinuses; and the sphenoid sinus, which is located on the upper posterior wall of the nasal cavity. The sinuses have two main functions: because they are filled with air, they help keep the weight of the skull within reasonable limits, and they act as resonance chambers for the human voice.
The nasal cavity is lined with respiratory mucosa along with its adjacent spaces. Normally, the nasal mucosa contains mucus-secreting glands and venous plexuses; Its top cell layer, the epithelium, consists mainly of two cell types, ciliated and secretory cells. This structural design reflects the specific auxiliary functions of the nose and upper part
