(i) Transport of oxygen. The haemoglobin present in the red blood calls takes the oxygen from alveoli of the lungs. The oxygen is carried by blood to all parts of the body. As the blood passes through the tissues of the body, the oxygen from the blo
1. Transport of oxygen . It is transported from respiratory organs to body cells . (i) Haemoglobin helps in the transport of oxygen. In the alveoli of the lungs , the haemoglobin oxygen. In the alveoli of the lungs , the haemoglobin (Hb) present in red
1)Across cell membranes, oxygen and carbon dioxide move or transport via simple diffusion, and no...
It does this by damaging the cilia, tiny hairlike structures whose job it is to keep the airways clean.它是通过破坏纤毛来实现的，微小的毛发状结构，其作用是保持气道清洁。It then fills the alveoli, tiny air sacs that enable the exchange of oxygen and carbon dioxide between the lungs and bloo...
Carbon dioxide is a molecule with the molecular formula CO2. The linear molecule consists of a carbon atom that is doubly bonded to two oxygen atoms, 0=C=0. Although carbon dioxide mainly consists in the gaseous form, it also has a solid and a liquid form. It can only be solid when ...
There are two ways that oxygen is transported in the blood: Dissolved in the blood plasma (1.5%); and Bound to hemoglobin (98.5%). Most oxygen is transported by hemoglobin inside the red blood cell. Oxygen is poorly soluble in water, thus very lit...
Now, we have special bins for different types of garbage, and the environment in our community has been much improved. Secondly, planting more trees is also a great way to protect the environment. Trees can absorb carbon dioxide and release oxygen, which can improve air quality. They can ...
During a run, your body needs to replenish oxygen and release carbon dioxide, which accumulates faster as you work harder. With a few simple breathing techniques for running, you can breathe more efficiently, increasing your oxygen intake and letting go of more CO2 with each breath. Proper brea...
the laying of drainage system and detergent used to grow, consume the oxygen in the water, fish died, deterioration of ecosystem. Human activities can make a lot of industrial and agricultural pollutants into the water, the water is polluted. The world each year about 4200 sewage into the riv...
