The respiratory system
The respiratory system supplies the body with oxygen and expels carbon dioxide.
Blood containing carbon dioxide flows from veins throughout the body to the heart, and then the heart pumps it to the lungs. Small air sacs (alveoli) in the lungs remove the carbon dioxide from the blood and release it into the lungs where it is exhaled.
the respiratory system
Breathing involves getting oxygen into your system and it expels carbon dioxide, which is a waste.
The respiratory system provides the mechanism for the body to obtain oxygen and excrete carbon dioxide.
The clam has two siphons. The excurrent siphon (which expels water and waste out of the clam) and the incurrent siphon (which brings oxygen and food and water into the clam).
Tt breathes or takes in CO2 through its leaves through photosynthesis during the day and takes out the carbon to make sugars for the plant to grow and expels oxygen as a by-product.
The body expels viruses by itself, using white blood cells.
When you inhale, your diaphragm and rib muscles contract, expanding your chest cavity and allowing air to be drawn into your lungs. This process brings oxygen into the body. When you exhale, your diaphragm and rib muscles relax, causing your chest cavity to decrease in size and push the air out of your lungs. This process expels carbon dioxide from the body.
Amoeba have a CONTRACTILE VACUOLE that expels water so that is won't burst.
Well one way biotechnology is involved in the brewing process is through yeast. Yeast eats the sugars in the wort and expels carbon dioxide and alcohol!
Paramecium does not have a respiratory system like humans do. It absorbs oxygen directly from its environment through its cell membrane, and expels carbon dioxide in a similar manner.
