the diaphragm tightens (moves down) expanding the lungs. This expansion creates the pressure in the lungs to decrease. Since nature always strives for equilibrium, high pressure moves to low pressure areas --> air fills the lungs. the diaphragm relaxes, moving back up in the chest cavity, increasing the pressure on the contents in the lungs. The air escapes the lungs to reach the lower pressure area outside our body.
The movement of gases in the diagram is accomplished through the process of diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, leading to equal distribution. In the context of gases, it allows for the exchange of gases across membranes such as in the respiratory system.
The movement of gases is called diffusion. It is the process by which gases like oxygen and carbon dioxide move across a concentration gradient to reach equilibrium in a space.
The process that accomplishes the movement of gases illustrated by the arrows in the diagram is diffusion. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, resulting in the equal distribution of molecules. In this case, gases are moving down their concentration gradient through the process of diffusion.
Diffusion is the process that allows movement of gases and ions from areas of high concentration to low concentration. This process occurs passively, driven by the concentration gradient, and does not require energy input from the cell.
The passive movement of gases is called diffusion. It is the process by which gases move from an area of high concentration to an area of low concentration in order to reach equilibrium.
The process that accomplishes the movement of gases illustrated by arrows in the diagram is called diffusion. Diffusion is the spontaneous movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.
The process that accomplishes the movement of gases shown by the arrow in the illustration is called diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. It occurs due to the random motion of particles.
Simple Diffusion
The process is called diffusion, where gases move from an area of high concentration to an area of low concentration through small pores. This movement is driven by the random motion of gas molecules.
The movement of the chest that brings air into the lungs is called inhalation, and it is facilitated by the contraction of the diaphragm and intercostal muscles. Exhalation is the process of removing waste gases from the lungs, which is typically a passive process where the diaphragm and intercostal muscles relax.
Convection is the process by which energy is transferred in gases and liquids. It involves the movement of the fluid due to differences in density caused by temperature variances. Warmer, less dense fluid rises, while cooler, denser fluid sinks, creating a continuous circulation to transfer heat energy.
The process most responsible for temperature changes is the greenhouse effect, where certain gases in the Earth's atmosphere trap heat from the sun and prevent it from escaping back into space, leading to a warming of the Earth's surface.
