external respiratory is the name given to the way organisms take in oxygen for respiratory and get rid of carbon dioxide and water vapour, which are the wastes from respiratory.

gaseous exchange
oxygen- (inhaled air) 21%- (exhaled air) 16%. carbon dioxide- (inhaled air) 0.4%-exhaled air 4%. nitrogen- (inhaled air) 78%-(exhaled air) 78%. water vapour- (inhaled air) varies- (exhaled air) increased

the carbon dioxide in the blood of the capillaries moves through their walls of the alveoli into the inside of the alveoli.

breathing.
to inhale:1) the intercostal muscle contract. this cause the ribs to move up and out. 2) the diaphragm contracts. this causes it to move up and down.3) thus the volume of the thorax (ribcage) increases. 4) this causes the pressure on the lungs to decrease. 5) air is sucked in
to exhale: 1) the intercostal muscles relax. this causes the ribs to move down and in. 2) the diaphragm relaxes. this causes it to arch up. 3) thus the volume of the thorax decreases.4) this causes the pressure on the lungs to increase. 5) air is forced out.
breathing
when a person exercises, the respiratory rate increases in the muscles of the body.

how the organs of the respiratory system interact with the organs of the circulatory system: the heart pumps through the pulmonary artery to the lungs. this artery divides up into the capillaries that surround the alveoli in the lungs
how the organs of the respiratory system interact with the organs of the circulatory system: the capillaries that surround the alveoli in the lungs join up to form the pulmonary vein, which carries blood from the lungs back to the heart.
how the organs of the respirator system interact with the organs of the digestive system: the trachea and the oesophagus are very close together going through the chest. both tubes meet in the throat area called the pharynx. Acid produced by the stomach will help kill bacteria that may be in the phlegm. There is a flap of tissue called the epiglottis that covers the entrance to the trachea when a person swallows. this prevents food from going 'down the wrong way'.
