what is the difference between internal and external gas exchange?
475747
External respiration refers to gas exchange that occurs in the alveoli, whereas internal respiration refers to gas exchange that occurs in the tissue. Both are driven by partial pressure differences.

The main difference between enthalpy and internal energy is that enthalpy is the heat absorbed or evolved during chemical reactions that occur in a system where as internal energy is the sum of potential and kinetic energy in a system.

The lungs bring oxygen into the body when breathing in and send carbon dioxide out of the body when breathing out. Carbon dioxide is a waste gas produced by the cells of the body. The process of breathing in is called inhalation. The process of breathing out is called exhalation.

explain difference between ventilation and respiration? ventilation is the movement of air in and out of the lungs, respiration is the exchange of oxygen and carbon dioxide.

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. The oxygen-rich blood returns to the heart.

A gas, on the other hand, has a vol- ume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.

Gas exchange is the intake of oxygen and the excretion of carbon dioxide at the lung surface. Oxygen moves into the blood and carbon dioxide moves out of the blood. Cell respiration is the process that releases energy from the food. ... They must be kept out of the delicate lung tissue.

Breathing involves inhale of oxygen from the atmosphere into the lungs and exhale of carbon dioxide from the lungs into the atmosphere ; whereas cellular respiration involves breakdown of glucose into carbon dioxide and water in living cells, releasing energy.

metabolizing tissues. External Respiration: External respiration refers to the gas exchange across the respiratory membrane of lungs. Internal Respiration: Oxygen diffuses out from the blood into tissue during internal respiration.

What is the difference between internal and external commands? Internal commands are commands that are already loaded in the system. They can be executed any time and are independent. On the other hand, external commands are loaded when the user requests for them.

Difference Between Internal and External Business Environment. The key difference between internal and external business environment is that internal environment is specific and has a direct impact on the business, whereas external environment has an impact on all business groups, not just one particular business.

The difference between external and internal combustion engines is quite straightforward and is made obvious by the difference in their names. In an external combustion engine, the fuel isn't burned inside the engine. With an internal combustion engine, the combustion chamber lies right in the middle of the engine.

Gas exchange is the intake of oxygen and the excretion of carbon dioxide at the lung surface. Oxygen moves into the blood and carbon dioxide moves out of the blood. Cell respiration is the process that releases energy from the food. It happens in all cells.

Gas exchange: The primary function of the lungs involving the transfer of oxygen from inhaled air into the blood and the transfer of carbon dioxide from the blood into the exhaled air.

Oxygen enters the lungs, then passes through the alveoli and into the blood. The oxygen is carried around the body in blood vessels. Carbon dioxide moves into the blood capillaries and is brought to the lungs to be released into the air during exhalation.
499773
External respiration also involves gas exchange, the exchange of oxygen and carbon dioxide between body cells and blood cells. ... Internal respiration is known as cellular respiration and is the chemical process by which glucose is broken down and energy (ATP) produced.

The external location of the lungs will not allow the pressure to be created between the atmosphere and the lungs. So, lungs are located inside the body. However, the gills are located outside of the body as they prevent the entry of the water inside the body of the organism.
