In a part of our brain called medulla oblongata, there is a respiratory centre which consists of a inspiratory centre, expiratory centre and pneumotaxic higher controller.
The inspiratory centre generates basal ramp signal to the main respiratory muscle of our body which is our diaphragm to contract. Expiration occurs without any neuronal intervention via elastic recoil of our longs and it occurs after the Hering-Breuer Reflex(cessation of inspiratory signal upon detection by stretch receptors).
So,that's the physiology part...below is what should be covered within the domain of Biology.
INSPIRATION
Outer Intercostal Muscle contracts
Inner Intercostal Muscle relaxes
Diaphragm contracts
Thoracic Volume increases
Rib cage moves forward and upward
Intra-thoracic pressure decreases
For EXPIRATION, the opposite occurs
Note that there are other muscles involved in breathing as well and these muscles can be classified as primary, accessory and airway respiratory muscles.
Primary - Intercostal Muscles, Diaphragm
Accessory(commonly used during strenuous exercise, Asthma or other respiratory illness)- sternoceidomastoid muscle, pectoralis major, quadratus lumborum and more.
Airway(people who snores a lot have inactivity in this muscles during sleep) - Laryngeal, Pharyngeal and genioglossus.

Do human respire?
Yes, humans do respire. Respiration is one of the seven life processes, you have to respire to live, humans are living things so they do respire.
Do animals and plants respire like humans?
not like humans but they do respiration but how do they respire then ?
Why do humans sweat from armpits?
Well...humans sweat all over our skin. We respire sweat from our pores. Sweat from our armpits smell because of the bacteria wastes.
Stored form of sugar in humans?
Glycogen is the stored reserve of sugar in the body. It is converted into glucose if our muscles need to respire.
Does a virus respire?
No. It is not alive so it doesn't need to respire.
How are humans similar with a butterfly?
We all do 7 same things we all move,reproduce,sensitive,nutrition,excrete,respire and grow and butterfly s do that
Which gas is taken in when fish respire?
Fish are like humans in the way that they need oxygen. Fish breathe in dissolved oxygen and pass out carbon dioxide.
How do penguins respire?
Penguins have a respiratory system similar to other birds. They breathe air into their lungs, where oxygen is extracted and carbon dioxide is expelled. Penguins can dive underwater for extended periods of time due to adaptations such as increased oxygen storage capacity and efficient use of oxygen in their muscles.
What organ of a fish is simailar to a humans respiratory system?
The fish use gills to respire. it is located on the lateral front side just behind the eyes of the fish
When do your muscles need to respire faster?
your muscle dont respire, your heart and lungs need to respire more whilst taking part in a physical activity.
Do plant cells respire?
Yes, plant cells do respire. Cellular respiration in plants involves the breakdown of glucose to release energy, which is used for various cellular activities. While plants also undergo photosynthesis to produce their own food, they still need to respire to obtain energy from the stored sugars.
Can plants respire and photosynthesize at the same time?
Yes, the can photosynthesize and respire at the same time.
