How do animals without blood get oxygen or food?
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.
Where in the lungs does oxygen and carbon dioxide diffuse across in the lungs?
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.
What are tubes inside the kidneys where urea and water diffuse from the blood?
nephrons
What substances diffuse into and what diffusen out of cells?
The substances flow from high concentration to low concentration through channels found in the cell membrane. Basically like a bridge.
Does water kills cell?
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.
What are the main substances that diffuse out of leaves?
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.
What molecules diffuse out of a leaf?
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.
What happens when blood flows through capillaries?
There is an exchange with oxygen, nutrients, and carbon dioxide and water vapor.
What determines whether oxygen and carbon dioxide diffuse into or out of the capillaries of the tissues near alveoli explain?
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.
How do animals breathe that live in water?
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.
Fish breathe in water with oxygen. What is the property of 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.
Because they trap oxygen from the atmosphere in the water for animals to breathe?
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.
