What else can I help you with?
Why is gaseous exchange continues in the lungs during expiration?
Because to carry out the process of diffusion of gas.
When oxygen diffuses into the bloodstream during gaseous exchange where does carbon dioxide pass to?
Carbon dioxide is released from the bloodstream into the alveoli in the lungs, to be exhaled during expiration.
What is bad about the stomata in plants?
Although not necessary, the stomata during gaseous exchange also favour transpiration and provide passage to the microorganisms.
How do plants obtain oxygen they need?
thru their leaves. Edited answer: Partly from the process of photosynthesis during day time and partly from the air through the stomata during gaseous exchange.
What is the significance of gaseous exchange in living organism?
It provides O2 and eliminates CO2 during respiration, It is essential for photosynthesis as it provides CO2 o plants .
What are the gases involved in the process in the gaseous exchange?
The primary gases involved in the process of gaseous exchange are oxygen (O₂) and carbon dioxide (CO₂). During inhalation, oxygen from the air enters the lungs and diffuses into the bloodstream, where it is transported to body tissues. Conversely, carbon dioxide, a waste product of cellular respiration, is carried from the tissues back to the lungs, where it is expelled from the body during exhalation. This exchange occurs in the alveoli of the lungs, facilitating the vital process of respiration.
What is gaseous exchange in plant?
Gaseous exchange in plants refers to the process by which plants take in carbon dioxide (CO2) from the atmosphere and release oxygen (O2) during photosynthesis. This exchange occurs primarily through small openings called stomata, located on the surfaces of leaves. During daylight, stomata open to allow CO2 to enter for photosynthesis, while oxygen, a byproduct of this process, is released back into the atmosphere. Additionally, during respiration, plants can take in oxygen and release CO2, particularly at night when photosynthesis ceases.
How lenticels are used by plants in gaseous exchange?
Lenticels are small, corky pores found on the surface of stems and roots of plants that allow for the exchange of gases like oxygen and carbon dioxide between the internal tissues and the external environment. They help in facilitating the intake of oxygen needed for respiration and the release of carbon dioxide produced during metabolic processes, aiding in overall gaseous exchange in plants.
During eupnea, which muscles contract to facilitate expiration?
During eupnea, the diaphragm and external intercostal muscles contract to facilitate expiration.
What happens to the body during expiration?
You die
Which of the what is are removed by expiration Carbon dioxide vapor Oxygen Carbon dioxide and water vapor?
During expiration, carbon dioxide is removed from the body while oxygen is still present in the exhaled air. Water vapor is also expelled during expiration.
How does the leaf gaseous exchange take place?
Leaf gaseous exchange occurs through tiny pores called stomata on the surface of leaves. During photosynthesis, carbon dioxide enters the leaf through the stomata, while oxygen and water vapor exit the leaf through the same pores. This exchange of gases is crucial for the process of photosynthesis and respiration in plants.
