Physiology 2019-2020 Summary Quiz

Physiology

• The study of physiology is concerned with the functions and processes that occur within living organisms, including the structure, function, and behavior of cells, tissues, organs, and systems.

Cell Structure

• The structural unit of the body is the cell.

Cellular Organelles

• The mitochondria is the organelle responsible for energy production inside the cell, generating energy for the cell through a process called cellular respiration.

Cell Transport

• Cells achieve transport of essential substances across the cell membrane through various mechanisms, including passive transport (diffusion, osmosis) and active transport, which requires energy to move molecules against their concentration gradient.

Cell Nucleus

• The nucleus of a cell contains the majority of the cell's genetic material, organized into structures called chromosomes, which carry the genetic instructions necessary for the development and function of an organism.
