What plant inhales most Co2?

Phytoplankton, found in oceans and freshwater bodies, are known to absorb large amounts of carbon dioxide through photosynthesis. They play a significant role in carbon sequestration and are considered one of the most efficient CO2 absorbers among plants.


Can pollen act as an antigen?

Yes, pollen can act as an antigen by triggering an immune response in the body. When someone with allergies inhales pollen, their immune system may mistakenly perceive it as a threat and produce antibodies against it, leading to symptoms such as sneezing, itching, and congestion.


What system exhales and inhales?

The respiratory system is responsible for inhaling and exhaling air. It includes structures such as the lungs, trachea, and diaphragm, which facilitate the exchange of oxygen and carbon dioxide. During inhalation, the diaphragm contracts, allowing air to enter the lungs, while exhalation occurs when the diaphragm relaxes, pushing air out. This process is essential for maintaining the body's oxygen supply and removing waste gases.


What causes a person to inhale?

A person inhales when the diaphragm and intercostal muscles contract, causing the chest cavity to expand and the lungs to fill with air. This process is controlled by the autonomic nervous system and regulated by the brainstem.


How does the cycle of respiration go?

as a person inhales oxygen it goes through the pharynx towards the trachea or windpipe and goes to the lungs. in the lungs the exchange of gases in the blood happen in the alveoli where in blood releases carbon dioxide and receives oxygen before returning to the heart. the carbon dioxide is then exhaled through the opposite direction but same passage as of the inhalation. the oxygenated blood that returned to the heart is then pumped back to the body for systemic circulation delivering oxygen to the different cells of the body and again collecting carbon dioxide.
