What does internal and external respiration mean?
External respiration refers to the act of mechanically pulling air into the lungs via breathing. Internal respiration is the exchange of gasses from blood to tissue and vice versa.
What is the difference from respiration and breathing?
Internal Respiration: Is changing food (glucose) into energy. External Respiration: Is breathing in and out.
Why is the continual exchange of gases in both external and internal respiration essential for survival?
The continual exchange of gases in external respiration allows oxygen to enter the bloodstream and carbon dioxide to be removed. This oxygen is then transported to cells throughout the body for energy production, while carbon dioxide is expelled from the body during internal respiration. This gas exchange process is essential for cells to function properly and for overall survival.
What is the difference between external ventilation and internal ventilation?
External respiration, the process by which gases are exchanged between the atmosphere and the pulmonary loop of circulationWhereas,Internal respiration: the is the gaseous exchange between the blood and tissue ( and also cells)
Is the exchange of gases within the cells of the body known as internal respiration?
No. The exchange of gases between the blood and tissue cells is called internal respiration. External respiration refers to the exchange of gases between the blood and the air inside of the alveoli of the lungs.
What is the difference between the two types of respiration?
External respiration refers to the exchange of gases between the lungs and the blood, while internal respiration is the exchange of gases between the blood and the tissues. External respiration involves the intake of oxygen and release of carbon dioxide in the lungs, while internal respiration occurs in the body's tissues.
What are the cellular respiratory processes that lungs perform?
The lungs perform the following cellular respiratory processes - pulminory ventilation external respiration internal respiration
What does internal and external cells mean?
Internal cells refer to cells that are located inside an organism, such as human cells within the body. External cells refer to cells that are found outside an organism, such as bacterial cells in the environment. The distinction between internal and external cells is based on their location relative to the organism.
Do mammals undergo respiration?
Yes, mammals undergo respiration, which is the process of exchanging gases between their bodies and the environment. They primarily use lungs to take in oxygen and expel carbon dioxide. This process is essential for cellular metabolism and energy production. Mammalian respiration can be categorized into two types: external respiration (gas exchange in the lungs) and internal respiration (gas exchange at the cellular level).
What are the 2 main types of muscles in respiration and how do they work?
muscle of respiration: diaphragm, external intercostrals and internal intercostrals - internal intercostral- pull ribs up and out - external intercostrals- pull ribs down and in - diaphragm-contracts in preparation for sneezing,coughing,crying,laughing and weight lifting.
When air enters the alveoli of human lungs is the oxygen it contains truly in the internal environment of the human?
No. This is an common misconceptiion. Respiration is considered external if it occurs in the lungs. When it occurs in body tissues it is considered internal respiration.
What is the difference between internal and external respiration?
External Respiration is the exchange of O2 and CO2 between the body and the environment. It involves moving air in and out of the lungs and the exchange of gases between the alveoli and the blood capillaries. The gases must also be exchanged between the blood capillaries and the cells of the body. This is called internal respiration. Some sources say this is the same as tissue respiration, but to me that means the chemical reactions which take place in our cells to release energy, the most usual of which is glucose + oxygen --> carbon dioxide and water.
