What is external respiration and internal respiration?
External respiration is to breathe and facilitate gas exchange in the lungs or an analogous body cavity, depending on the organisms anatomy. Cellular respiration is the process of oxidative phosphorylation, where ATP energy is generated from biomolecules by the cell. In aerobes, the process involves a series of electron steps and oxygen is the terminal electron acceptor
Why must complex muticellular organisms have transport systems?
Large organisms need transport systems to supply all their cells with food, oxygen and other materials.Multi-cellular organisms are too big and not all of their cells have contact with the external environment. All organisms need to exchange substances with their environment - take in needed molecules and get rid of waste. A uni-cellular organism can use the processes of osmosis, diffusion and active transport to transport substances in and out of the organism, which is in this case just one cell. But as organisms increase in size, they need a specialized transport system to exchange substances between the internal environment and the external environment. Interestingly enough, osmosis and diffusion are still the important mechanisms at the cellular level.
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.
How lenticels are used by plants in gaseous exchange?
Lenticels are small, corky pores found on the surface of stems and roots of plants that allow for the exchange of gases like oxygen and carbon dioxide between the internal tissues and the external environment. They help in facilitating the intake of oxygen needed for respiration and the release of carbon dioxide produced during metabolic processes, aiding in overall gaseous exchange in plants.
What provides a boundary between the internal and external environment of all cells?
The cell membrane, also known as the plasma membrane, provides a boundary between the internal and external environment of all cells. It is a semi-permeable barrier that regulates the passage of substances in and out of the cell, allowing for the maintenance of cellular homeostasis.
What is the fluid link between the external and internal environment?
The fluid link between the external and internal environment is the plasma membrane of cells. It acts as a selectively permeable barrier that regulates the passage of substances in and out of the cell, maintaining the cell's internal environment while interacting with the external environment.
What is the balance between the internal and external environment?
walls
This body system is responsible for the exchange of gases between the blood and the external environment?
This body system that is responsible for the exchange of gases between the blood and the external environment.
Allows communication between the internal and external cell environment?
The cell membrane allows communication between the internal and external cell environment. This is due to is selective permeable nature of the membrane.
What are the differences between internal and external environment?
The differences between internal and external environment is: Internal environment involve within the organization, which are the employee attitudes,new equipment,strategy,work forces. The organization has the control of these matters because it happen within the organization unless like external environment. AND for the external environment,is clearly stated with the word external itself which means outside of the organizations which effect the changes in the organization which the organization does not have the control of it. External environment are involved by the PESTLE- Politic, Economy, Social, Technology, Legal and Environment.
What Keeps the bodys internal environment distinct from the external environment?
The body's internal environment is distinct from the external environment due to physiological processes such as homeostasis, which regulates factors like temperature, pH, and nutrient levels. Specialized structures like cell membranes, the blood-brain barrier, and the skin also help maintain this distinction by controlling the exchange of substances between the two environments. The body's ability to selectively absorb, excrete, and regulate the concentration of substances further reinforces the boundaries between internal and external environments.
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)
What allows communication between the internal and external cell environment?
cell(plasma) membrane
What is function of a protein in a cell?
It sends signals between the cells external and internal environment.
What cell structure that allows cummunication between internal and external cell environment?
The cell membrane is the structure that allows communication between the internal and external cell environment. It controls the movement of molecules in and out of the cell, helping to maintain homeostasis and respond to changes in the cell's surroundings.
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 external and internal stimuli?
internal is in and external is out
