HUMAN NUTRITION

Detailed explanation-1: -Here’s how the respiratory and digestive systems interact: Your digestive system (and the resulting absorption of nutrients from your food) provides your respiratory organs and tissue with the nutrients they need to work properly, per Texas A&M University.

Detailed explanation-2: -Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

Detailed explanation-3: -False, the digestive system doesn’t work to meet the need for oxygen. All living things have a digestive system, which is one of their most important organs. Our digestive system is the only organ that converts the food we eat into the energy we require.

Detailed explanation-4: -The respiratory system takes up oxygen from the air we breathe and expels the unwanted carbon dioxide. The main organ of the respiratory system is the lungs. Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).
