alveoli
the respiratory system provides oxygen for them
This system is called the respiratory system. It exchanges oxygen that the cells need to make energy for carbon dioxide which is a waste product that the cells make.
Cytoplasm is the fluid inside a cell, so since the respiratory system is made of cells, the cytoplasm is inside of the respiratory systems cells.
Respiratory system
the lungs
The respiratory system is most directly involved in the transport of oxygen in humans. Oxygen enters the body through the lungs during inhalation and is then transported by the circulatory system via red blood cells to tissues and organs where it is needed for cellular respiration.
the lungs
Respiratory system provides O2 to digestive system which is essential for all cells and their working .
the red blood cells get oxygen or put out carbon dioxide through the capillaries in the alveoli of the lungs. They do this to help get oxygen for the cells in the body/ take away carbon dioxide from the cells
Excretory system gets rid of waste. Respiratory system supplies blood cells with oxygen.
