the lungs causes oxygen from the water to diffuse into the blood
Animals without blood, such as sea sponges, obtain oxygen and nutrients through diffusion. They rely on their porous body structures to allow oxygen and food particles to diffuse in and waste products to diffuse out. This process occurs through direct contact with their environment.
since the air in lungs have more oxygen than the blood in the surrounding, the oxygen will be difused to the blood, similerly the quantity of carbon dioxide in the surrounding blood will be more compared to that in the lungs. so again difussion takes place, thus happens the exchange. no osmosis(the exchange of water from a place with a high concentration of water to a place with low concentration of water) but there is diffusion.
nephrons
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
neurons die as a result of cessation of oxygen supply and dehydration causes blood viscosity. therefore if blood is viscous there would be poor oxygen supply to the brain because the hemoglobin in the blood carries the oxygen we require for cellular respiration.
The main substances that diffuse out of leaves are oxygen, water vapor, and excess carbon dioxide. This process of diffusion occurs through small openings called stomata located on the surface of leaves.
Oxygen and water vapor are molecules that diffuse out of a leaf through tiny pores called stomata. Oxygen is produced during photosynthesis, while water vapor is a byproduct of transpiration, the process where plants lose water through their leaves.
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
its the blood which act as a transporter and the concentration of blood determines that oxygen will diffuse faster than carbon dioxide due to its small molecular weight but if diffusion occur in such manner then amount of carbon dioxide will be automatically more. carbon dioxide is a toxic gas and its presence in more amount can causes problems by increasing the PH of blood,but carbon dioxide has an affinity for water. The excess carbon dioxide gets dissolve in water or simply we can say in plasma of blood more than oxygen so its its excrete in lungs and passes from lungs to mouth in atmosphere following bronchioles and bronchi.
It depends on the animal. Some have gills that allow oxygen to diffuse from the water into the blood. Some must rise to the surface every so often to breathe air. Some have a low enough oxygen requirement relative to their surface area that oxygen diffuses into their bodies from the water.
The property of water that allows fish to breathe is its ability to dissolve oxygen. As water flows over the fish's gills, oxygen molecules from the water diffuse into their bloodstream, allowing them to extract oxygen for respiration.
The lungs are the organs that "trap" oxygen from the atmosphere for animals to breath. Lungs do not really trap oxygen, however, they present a tissue to the oxygen-rich air in which the oxygen may diffuse into, where it can be captured by the hemoglobin in the blood.
