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.

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.
not like humans but they do respiration but how do they respire then ?
Penguins breathe or respire in the same way that humans respire. They take air in through their nostrils where it travels to their lungs.
It is how animals respire, or breathe. We humans respire with lungs. Not all animals have lungs. For example, fish have gills, which they use to respire. Frogs breathe through their skin. All mammals (animals with hair) have lungs though, so they breathe like we do.
Well...humans sweat all over our skin. We respire sweat from our pores. Sweat from our armpits smell because of the bacteria wastes.
Glycogen is the stored reserve of sugar in the body. It is converted into glucose if our muscles need to respire.
When oxygen is not being delivered adequately to muscle, for example, during strenuous exercise, the cells begin to respire anaerobically to ensure muscle still derive needed energy.
Yes, for humans, we let out carbon dioxide, but when plants let out something, it's oxygen
All organisms respire. Plants do not breathe, but they respire. Animals breathe to respire.
No. It is not alive so it doesn't need to respire.
We all do 7 same things we all move,reproduce,sensitive,nutrition,excrete,respire and grow and butterfly s do that
Fish are like humans in the way that they need oxygen. Fish breathe in dissolved oxygen and pass out carbon dioxide.
