Respiratory
RespiratoryOrgans of the respiratory system: nose, pharynx, larynx, trachea, bronchi, alveoli
alveoli
hormones
The reproductive cycle of a human is usually regulated by hormones.
Our lungs are part of the human respitory system. The exchange of gases from the outside of the body to the inside of the body take place in the here.
Restriction Enzymes.
through respiration
Gases takes place by nasal passage go to lungs to purifi.
Basically, the lungs exchange inwards of oxygen for outwards of waste gases.
Three (of many) are: * the muscular system and the skeletal system. All muscles move bones. * the circulatory system and the respiratory system meet in the lungs for the exchange of gases * the circulatory system and the urinary system meet in the kidneys where wastes are removed
Plants give out oxygen, take in carbon dioxide while Human give out carbon dioxide and take in oxygen
In the respiratory system, we see the exchange of gases. In this gas exchange, carbon dioxide (CO2) leaves the blood and goes into air in the lungs, and oxygen (O2) leaves the air in the lungs and goes into the blood. It is this gas exchange, which occurs in the alveoli, that permits oxygenation of the blood and keeps us alive.
