Breathing starts at the nose and mouth. You inhale air into your nose or mouth, and it travels down the back of your throat and into your windpipe, or trachea. Your trachea then divides into air passages called bronchial tubes.
For your lungs to perform their best, these airways need to be open during inhalation and exhalation and free from inflammation or swelling and excess or abnormal amounts of mucus.
The LungsAs the bronchial tubes pass through the lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has over 300 million alveoli.
The alveoli are surrounded by a mesh of tiny blood vessels called capillaries. Here, oxygen from the inhaled air passes through the alveoli walls and into the blood.
After absorbing oxygen, the blood leaves the lungs and is carried to your heart. Your heart then pumps it through your body to provide oxygen to the cells of your tissues and organs.
As the cells use the oxygen, carbon dioxide is produced and absorbed into the blood. Your blood then carries the carbon dioxide back to your lungs, where it is removed from the body when you exhale.

Answer:
Sensorimotor stage
Explanation:
The sensorimotor stage of development, is the first stage of cognitive development of infants, children, and adolescents. A child of about 2 years of age, is in the sensorimotor stage.
Infants at the early stage of life, sense what is directly in front of them. Their learning pattern at this early stage is a trial and error pattern involving gripping, throwing etc.
As soon as the object is taken away from the direct view of an infant, it ceases to exist to him/her. This is because objects exist to infants when they can sense them and interact with them.
.A significant development during the sensorimotor stage is the understanding of an infant that objects exist and that events occur in the world independently from their actions and what they sense.The infant now has a representation of the object and realizes the object can still exist independently.This is known as object permanence
