Chapter 3: Systems Working Together Flashcards
a series of chemical reactions in which the chemical energy in molecules such as glucose is transferred into ATP molecules.
Glucose+oxygen → carbon dioxide+water
cellular respiration
tasteless and colourless gas in which molecules (02) are made up of two oxygen atoms
Oxygen
a colourless gas in which molecules (CO2) are made up of one carbon and two oxygen atoms
Carbon dioxide
To get oxygen into your body and carbon dioxide out
Respiratory system
To transport oxygen and nutrients to your body cells, and wastes such as carbon dioxide away from them
Circulatory system
remove oxygen from
Deoxygenated
to supply you body with nutrients such as lipids so that it functions effectively
Digestive system
The system which removes waste products of a variety of necessary chemical reaction
Excretory system
largest gland in the body. breaks down many substances harmful to the body and has many other essential functions.
Liver
the part of the digestive system between the stomach and large intestine, where much of the digestion of food and absorption of nutrients takes place
Small intestine
the taking in of a substance; for example, from the intestine to the surrounding capillaries.
Absorption
the part of the digestive system, where water is absorbed from the waste before it is transported out of the body
Large intestine
the process of eliminating or expelling waste matter.
Excretion
body organs that filter the blood, removing urea and other wastes
Kidney
molecule used by cells in chemical reactions that require energy. ATP is a product of cellular respiration
ATP
