The red blood cells (hemoglobin) give up respiratory gasses to other cell tissue through the thin capillary walls. Like you said this happens by diffusion. The gas molecules are small and can pass through the thin cell membranes and capillary walls into the tissue, and diffusion means they move from an area of higher concentration (the hemoglobin) to an area of lower concentration (the cells which have lower concentration because they have used some of the oxygen they had).
To bring oxygen into the body, transfer gases into the tissues, and remove carbon dioxide from the body.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
In the alveoli, oxygen (O2) and carbon dioxide (CO2) are the two gases that diffuse. Oxygen diffuses from the alveoli into the blood, where it is transported to tissues for cellular respiration. Conversely, carbon dioxide diffuses from the blood into the alveoli to be exhaled from the body. This gas exchange is essential for maintaining proper respiratory function and metabolic processes.
The three functions of the blood when the circulatory system is working with the respiratory system are to take in needed gases from the lungs, expel waste gases from the tissues, and carry hormonal messages that communicate the body's needs to the respiratory adn circulatory systems.
Flatworms, such as planarians, lack specialized respiratory organs and instead rely on their body surface for gas exchange. Their flat, thin bodies provide a large surface area relative to volume, allowing oxygen to diffuse directly into their cells and carbon dioxide to diffuse out. This process is effective due to the flatworms' moist environment, which facilitates the diffusion of gases. Overall, their entire body surface functions as the respiratory surface.
Respiratory system
to exchange gases in the body.
The lungs are part of the respiratory system, which is responsible for the exchange of gases between the body and the environment. This system includes structures such as the trachea, bronchi, and alveoli, facilitating the intake of oxygen and the expulsion of carbon dioxide. The respiratory system works closely with the circulatory system to deliver oxygen to the body's tissues and remove waste gases.
The four respiratory events in the human body are ventilation, external respiration, transport of gases, and internal respiration. Ventilation refers to the movement of air in and out of the lungs. External respiration involves the exchange of oxygen and carbon dioxide between the alveoli and the blood. Transport of gases occurs as oxygen and carbon dioxide are carried in the bloodstream, while internal respiration is the exchange of gases between the blood and body tissues.
