How is oxygen and carbon dioxide transported in human beings

• Facebook • WhatsApp Oxygen and Carbon Dioxide are two of the most essential gases for human beings. As they play a vital role in respiratory process. Oxygen is required by our body for energy production, and carbon dioxide is a waste product that needs to be removed from our body. The process of transportation of these gases is crucial to maintain the body’s equilibrium and ensure proper functioning. In this blog post, we will explore how oxygen and carbon dioxide are transpoted in human beings in more details. Transportation of Oxygen : The process of transportation of oxygen in human being starts in the lungs. The air we inhale contains around 21% oxygen, which enters our body and diffuses into the blood vessels that surround the alveoli in the lungs. The oxygen the binds with the hemoglobin in the red blood cells, forming oxyhemoglobin. The oxyhemoglobin is then transported by the circulatory system to the various parts of the body, where it dissociates to release oxygen. The oxygen diffuses into the cells, and the hemoglobin returns to the lungs, where it binds with more oxygen. The amount of oxygen that can be transported by the blood is determined by the concentration of hemoglobin in the blood. Hemoglobin is a protein found in the red blood cells that binds with oxygen. Each hemoglobin molecule can carry up to four molecule of oxygen. The amount of oxygen that can be carried by the blood also depends on the partial pressure of oxygen in the blood. When the partial...

About 7 per cent of CO 2 ​ is carried in a dissolved state through plasma. Haemoglobin is a red coloured iron containing pigment present in the RBCs. O 2 ​ can bind with haemoglobin in a reversible manner to form oxyhaemoglobin. Each haemoglobin molecule can carry a maximum of four molecules of O 2 ​ . CO 2 ​ is carried by haemoglobin as carbamino-haemoglobin (about 20-25 per cent). This binding is related to the partial pressure of CO 2 ​ .

Solution → Transport of Oxygen: The respiratory pigments (haemoglobin) present in red blood cells takes up the oxygen from the air to the lungs. They carrt the oxygen to tissues which are dificient in oxygen. → Transport of carbon dioxide: Carbon Dioxide is more soluble in water. Hence, it is mostly transported from body tissues in the dissolved from in our blood plasma to lungs where it diffuses from blood to air in the lungs and then expelled out through nostrils.

Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. This barrier between air and blood averages about 1 micron ( 1/ 10,000 of a centimeter, or 0.000039 inch) in thickness. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body (see Function of the Heart The heart and blood vessels constitute the cardiovascular (circulatory) system. The heart pumps the blood to the lungs so it can pick up oxygen and then pumps oxygen-rich blood to the body.... read mor...

When we inhale air, oxygen reaches the alveoli in lungs. Thin capillaries surround alveoli. These alveoli carry blood in them. The oxygen diffuses from the alveoli walls to the blood in capillaries. This blood travels all through the body. Haemoglobin binds with oxygen and carries along the body. The O 2 is present in the blood diffuses into the cells since the blood ccntain high concentration of oxygen while cells contain a low concentration of oxygen. CO 2 is produced as a waste product in respiration in the cells of tissues. This CO 2 diffuses into the blood as the concentration of CO 2 is low in the blood. Blood carries CO 2 back to lungs, where it diffuses into aIveoli, then trachea, nostrils and then out of the body into the air. CO 2 is transported in dissolved form in our biood.
