Gas Exchange and Cellular Respiration

cellular respiration

process that living things do which converts food energy into ATP energy

aerobic respiration

Respiration that requires oxygen; happens in the mitochondria of the cell

anaerobic respiration

Respiration that happens when there is no oxygen. This produces lactic acid, and happens in the cytoplasm of the cell

yeast

unicellular fungi

ATP

(adenosine triphosphate) main energy source that cells use for most of their work

Mitochondria

Powerhouse of the cell, organelle that is the site of ATP (energy) production

Glucose

the form of sugar that circulates in the blood and provides the major source of energy for body tissues.

lactic acid

product of anaerobic respiration in many types of cells, including human muscle cells

Circulatory system

system that provides a flow of nutrients and Oxygen throughout the body

respiratory system

system that brings oxygen into the body, so it can get into the blood cells. It also releases carbon dioxide

nervous system

system that detects high CO2 levels in the blood, and sends signals to the other two systems to pump the heart faster, and breathe faster

Arteries

Type of blood vessel that carries blood AWAY from the heart

Veins

Type of blood vessel that carries blood TOWARD the heart
