Respiratory and Excretory Review

Front

What is the main function of the respiratory system?

Back

The main function of the respiratory system is to take in oxygen and expel carbon dioxide, facilitating gas exchange in the body.

Front

What are alveoli?

Back

Alveoli are tiny sacs of lung tissue where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be removed.

Front

What is the role of the diaphragm in respiration?

Back

The diaphragm is a large muscle located below the lungs that contracts and relaxes to help move air in and out of the lungs.

Front

What organ filters blood in the excretory system?

Back

The kidney is the major organ of the excretory system that filters blood to remove waste and excess substances.

Front

What is the respiratory system responsible for?

Back

The respiratory system is responsible for taking in oxygen and removing carbon dioxide from the body.

Front

Define the term 'bronchi'.

Back

Bronchi are the large air passages that lead from the trachea to the lungs, branching into smaller bronchioles.

Front

What is the function of the pharynx?

Back

The pharynx is a muscular tube that connects the mouth and nasal passages to the esophagus and larynx, playing a role in both respiration and digestion.

Front

What is gas exchange?

Back

Gas exchange is the process by which oxygen is taken into the body and carbon dioxide is expelled, occurring primarily in the alveoli.

Front

What is the trachea?

Back

The trachea, also known as the windpipe, is a tube that connects the larynx to the bronchi, allowing air to pass to and from the lungs.

Front

What is the main waste product removed by the excretory system?

Back

The main waste product removed by the excretory system is urea, which is produced from the breakdown of proteins.
