Where do digestion and respiration both occur?

Where do digestion and respiration both occur?

The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.

What is respiration and digestion?

NUTRITION AND DIGESTION. RESPIRATION. I. Respiration is the word we use for gas exchange. The gasses need to be exchanged because animals use oxygen to extract energy from their food molecules and because carbon dioxide is a principle waste product of those chemical reactions (think back to cellular respiration.

How are cellular respiration and photosynthesis similar and different?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

What is the difference between the respiratory system and digestive system?

Explanation: The respiratory system is primarily used to transport air, while the digestive system is used to transport fluids (such as water) and solids (such as food particulates). The respiratory and the digestive systems share the region of the mouth and upper throat, where air, fluids, and solids can be mixed.

What role does the digestive system play in cellular respiration?

The digestive system breaks down the food into molecules. The cells then convert those molecules into a form of energy they can use. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration.

Which structure is shared between the respiratory system and the digestive system?

There are three main divisions of the pharynx: the oral pharynx, the nasal pharynx, and the laryngeal pharynx. The latter two are airways, whereas the oral pharynx is shared by both the respiratory and digestive tracts.

Which structure of the respiratory system is the site of gas exchange?

During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

How are the processes of respiration and digestion related?

In general sense,respiration is the production of energy from this simpler nutrients(fatty acid or glucose). So digestion helps to obtain the substrate/source which is then used to produce energy via respiration.

How are cells used in the digestive system?

Through the process of digestion, you break large nutrient molecules into smaller ones that your intestine absorbs into the bloodstream. Cells then take up these nutrient molecules and use them to build new molecules and provide for their cellular energy needs. Cells can also store the molecules for later use.

What makes up the last two steps of cellular respiration?

However, cellular respiration is aerobic, meaning it requires oxygen and utilizes the cell’s mitochondrion, a specialized structure of the cell where most of the ATP is made, for its last two steps: the Krebs cycle and the electron transport chain.

What’s the difference between anaerobic and cellular respiration?

Anaerobic means that it does not require oxygen. Fermentation begins the same as cellular respiration – with glycolysis. The glucose molecule is split in half. However, during cellular respiration, the pyruvic acid is further processed and sent to the citric acid cycle.
