Respiration
The process of breaking down glucose to release energy, this goes on in every living cell.
Aerobic Respiration
respiration with oxygen (glucose+oxygen=carbon dioxide+water+energy)
Diffusion
The movement of particles from an area of higher concentration to an area of lower concentration.
Diffuse
Raw materials and waste do this in and out of cells.
Circulatory system
This carries glucose, oxygen and carbon dioxide in the blood.
Anaerobic Respiration
respiration without oxygen (glucose=energy+lactic acid)
Cardiac Output
The volume of blood pumped per minute by each ventricle of the heart.
Cardiac Output Equation
Cardiac Output = Heart Rate x Stroke Volume
Stroke volume
The volume of blood pumped by a heart ventricle in a single contraction.
Heart rate
The frequency of heart contraction.
