a network of organs and vessels that transport blood throughout the body

Alveoli are tiny air sacs in the lungs where oxygen enters the blood and carbon dioxide leaves it.

Capillaries are the tiniest blood vessels in the body where oxygen, nutrients, and waste are exchanged between the blood and the cells.

oxygen-rich blood that is carried from the heart to the rest of the body through the arteries.

the blood that travels through the veins, carrying deoxygenated blood back to the heart.

Diffusion is the movement of particles from an area of high concentration to an area of low concentration until they are spread out evenly.

membrane bound organelles

Membrane-bound organelles are parts of a cell that are surrounded by a membrane, which helps them do specific jobs by keeping them separate from the rest of the cell. They are found in eukaryotic cells, like those of plants and animals.

what are some scenarios when anaerobic and aerobic respiration occurs

Aerobic Respiration Scenarios: Walking, Swimming Anaerobic Respiration Scenarios: Sprinting, Weightlifting

Independant, Dependant, and Control variables

the independent variable is what the person changes, the dependent variable is what is measured and observed in response to that change, and the controlled variables are kept constant to ensure that only the indep. variable affects the depen. variable

Fermentation is a process cells use to make energy when there isn’t enough oxygen. It happens in some cells, like muscle cells or yeast, and can produce things like lactic acid or alcohol.
