Describe process of gaseous exchange
WebThe transportation of gases is a very efficient process. Oxygen molecules get carried by the haemoglobin molecules of the red blood cells since it has a great affinity for oxygen. Each haemoglobin molecule binds to four molecules of oxygen. These oxygen molecules are picked up by haemoglobin and get transported by the blood to various tissues. WebGas exchange occurs at two sites in the body: in the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane, and at the tissues, where oxygen is released and carbon dioxide is picked up. External respiration is the exchange of gases …

WebDescribe the process of internal respiration; The purpose of the respiratory system is to perform gas exchange. Pulmonary ventilation provides air to the alveoli for this gas exchange process. At the respiratory membrane, where the alveolar and capillary walls meet, gases move across the membranes, with oxygen entering the bloodstream and ... WebThe process of pulmonary gas exchange removes CO 2 from the blood and replenishes the bloods O 2 supply. Gas exchange occurs down a pressure gradient, via a process known as ‘diffusion’. When we breathe in we inspire air consisting of a mixture of gases including O 2 and CO 2. These gases each have a pressure related to their …
WebMay 14, 2024 · The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Figure 16.2.4.1 Stoma. Normally stomata open when the light strikes the leaf in the morning and close during the night.
