|
need to eliminate oxygen
|
|
|
respiratory system
|
takes in O2 and lets out CO2
|
|
|
Cardiovascular system
|
circulates O2 and picks up CO2, which is brought back to the respiratory system
|
|
|
Ventilation
|
a method of increasing contact between the respiratory medium and the respiratory surface. It maintains a high concentration of oxygen in the alveoli and low carbon dioxide as we breathe in and out.
|
|
|
Gas exchange
|
occurs between the aveoli and the capillaries by diffusion, oxygen passes from the alveoli to the capillaries and carbon dioxide passes from the capillaries to the alveoli.
|
|
|
Cell respiration
|
the chemical reaction that occurs inside the cell and that results in the controlled production of energy in the form of ATP.
|
|
|
Bronchi:
|
The two main air passages into the lungs.
|
|
|
Diaphragm:
|
The main muscle used for breathing; separates the chest cavity from the abdominal cavity.
|
|
|
Epiglottis:
|
A flap of cartilage that prevents food from entering the trachea (or windpipe).
|
|
|
Esophagus:
|
The tube through which food passes from the mouth down into the stomach.
|
|
|
Heart:
|
The muscular organ that pumps blood throughout the body.
|
|
|
Intercostal muscles:
|
Thin sheets of muscle between each rib that expand (when air is inhaled) and contract (when air is exhaled).
|
|
|
Larynx:
|
Voice box.
|
|
|
Lungs:
|
The two organs that extract oxygen from inhaled air and expel carbon dioxide in exhaled air.
|
|
|
Lungs:
|
The two organs that extract oxygen from inhaled air and expel carbon dioxide in exhaled air.
|
|
|
Muscles attached to the diaphragm:
|
These muscles help move the diaphragm up and down for breathing.
|
|
|
Nasal cavity:
|
Interior area of the nose; lined with a sticky mucous membrane and contains tiny, surface hairs called cilia.
|
|
|
Nose hairs:
|
Located at the entrance of the nose, these hairs trap large particles that are inhaled.
|
|
|
Paranasal sinuses:
|
Air spaces within the skull.
|
|
|
Pharynx:
|
The throat.
|
|
|
Pleural membrane:
|
Covering the lung and lining the chest cavity, this membrane has 2 thin layers.
|
|
|
Pulmonary vessels:
|
Pulmonary arteries carry deoxygenated blood from the heart and lungs; pulmonary veins carry oxygenated blood back to the heart.
|
|
|
Respiratory center:
|
Area of the brain that controls breathing.
|
|
|
Ribs:
|
Bones attached to the spine and central portion of the breastbone, which support the chest wall and protect the heart, lungs, and other organs in the chest.
|
|
|
Trachea:
|
Tube through which air passes from the nose to the lungs (also known as the windpipe).
|
|
|
pharynx
|
throat
|
|
|
Larynx
|
voice box
|
|
|
Pulmonary artery:
|
an artery conveying venous blood from the right ventricle of the heart to the lungs.
|
|
|
Pulmonary vein:
|
• a vein conveying oxygenated blood from the lungs to the left atrium of the heart.
|
|
|
Carbon monoxide:
|
a chemical compound, CO, a colorless, odorless, tasteless, extremely poisonous gas that is less dense than air under ordinary conditions.
|
|
|
Kidney
(Part of the uninary tract) |
removes waste from the blood, waste is what makes up urine

|
|
Ureter
(Part of the uninary tract) |

|
Bladder
(Part of the uninary tract) |
what stores the urine until you “go to the bathroom”
(Part of the uninary tract) |
|
|
glomerulus
|
a group of capillaries that form a tight ball
• (Also called Malpighian tuft. a tuft of convoluted capillaries in the nephron of a kidney, functioning to remove certain substances from the blood before it flows into the convoluted tubule.) |
|
|
Osmoregulation
|
the control of the water balance of the blood, tissue or cytoplasm of a living organism.
