The function of the respiratory system is to deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs.Respiration includes the following processes: Pulmonary ventilation is the process of breathingâinspiration (inhaling air) and expiration (exhaling air).xternal respiration is the exchange if oxygen and carbon dioxide between the blood and air in the lungs, and internal resparation is the exchange of gases between blood cells of the body.

For this reason quail egg producers usually prefer to house their birds in cages. A cage 13 Ã 20 cm is large enough for two birds. The cage should have a solid metal or plywood roof to minimise head injuries if the birds take fright. Adult quail need 1.25â2.5 cm of feeder space per bird.Ample feed should be present, but if the trough is too full, excessive wastage will occur. Clean, fresh water should be provided at all times with a minimum of 0.6 cm of trough space per quail. Nipple drinkers and cups are suitable for adult quail.apanese quail are hardy birds that thrive in small cages and are inexpensive to keep. They are affected by common poultry diseases but are fairly disease resistant. Japanese quail mature in about 6 weeks and are usually in full egg production by 50 days of age.
