Glottis in humans is …….

Differences in Respiratory Systems:

1) Lizard respiratory system: The glottis, which is the opening to the lungs, is always closed in lizards. This means that they rely on different mechanisms for respiration, such as buccal pumping (using mouth movements) or lung ventilation through expansion and contraction of the entire body cavity.

2) Human respiratory system: Humans cannot run or breathe simultaneously, which means that we have to pause our breathing momentarily when engaging in exercise that requires running. This is because running increases our oxygen demand, and our respiratory system prioritizes delivering oxygen to the muscles over maintaining normal breathing.

3) Glottis in humans: The glottis in humans is positioned in the throat and is responsible for controlling airflow during breathing and vocalization. Unlike lizards, the glottis in humans opens and closes dynamically to allow the passage of air into the lungs.

Similarities in Respiratory Systems:

1) Gas exchange: Both lizards and humans have specialized lungs or lung-like structures that facilitate the exchange of gases, specifically oxygen and carbon dioxide. This exchange occurs in respiratory surfaces, such as alveoli in humans or lung sacs in lizards.

2) Respiratory muscles: Both lizards and humans have muscles involved in the process of breathing. In both cases, the muscles of the diaphragm and intercostal muscles play a vital role in expanding and contracting the chest cavity to facilitate inhalation and exhalation.

3) Need for oxygen: Both lizards and humans require oxygen for cellular respiration, which is the process by which food molecules are converted into energy. Oxygen is necessary for the production of ATP, the molecule that fuels cellular activities. Thus, both species have evolved respiratory systems to obtain and distribute oxygen throughout the body.

Difference:

1) In lizards, the glottis is always closed, while in humans, it opens and closes dynamically to control airflow.
2) Lizards use alternative respiration methods like buccal pumping, while humans rely on lung ventilation for respiration.
3) Humans cannot run and breathe simultaneously, while lizards do not have this limitation.

Similarity:
1) Both lizards and humans have specialized respiratory structures for gas exchange.
2) Respiratory muscles are involved in the breathing process for both lizards and humans.
3) Both species require oxygen for cellular respiration to produce energy (ATP).
