Brain of cell DNA gives the cell it's function
Nucleus
Energy production (powerhouse)
Mitochondria
This organelle is responsible for sorting, packaging and transporting proteins
Golgi apparatus
Endoplasmic Reticulum (ER)
A cell structure that forms a maze of passageways in which proteins and other materials are carried
from one part of the cell to another.

Lysosome
What is Ribosomes main function?
protein synthesis
what develops spindle fibers during cell division?
centrioles
Smooth ER function
Synthesis of lipids
Synthesis of proteins & it has ribosomes attached to it
Rough ER
Where is the pharynx located?
Located behind the mouth also part of the GI tract
Voice box
larynx
the windpipe; connects the larynx to the lungs; a passage through which air moves in the respiratory
system
Trachea
, What is the bronchi?
Main passageways, attached to the lungs
Bronchioles
progressively smaller tubular branches of the airways and connect to alveoli.
Alveoli
Tiny air sacs, site of O2 & CO2 exchange Occurs by diffusion (passive transport)
respiratory system
system responsible for taking in oxygen and releasing carbon dioxide using the lungs
Lungs
helps oxygen enter red blood cells
Diaphragm
The _______________ is a dome shaped sheet of muscle and tendon that serves as the main muscle of
respiration and plays a vital role in the breathing process.
Surfactant helps to prevent the alveoli from collapsing by ________.
interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar
fluid
Membrane around lungs, inside chest cavity
pleura
The passage of fluid to an organ or a tissue
perfusion
The amount of air breathed in normal inhalation or exhalation
Tidal volume
TLC (total lung capacity)
maximum volume of air that lungs can contain (6.0L)
Vital Capacity (VC)
amount of air exhaled after a maximal inspiration (TV+IRV+ERV)
