1. Breathing Cycle is a rhythmic process because contraction and relaxation of our chest takes place during breathing, But exchange of gases is a continuous process because it never stops it takes place all the time.
2. The blood clots if conducting tubes of a circulatory system develops a leak. The platelets will increase, which will minimize the leakage. ... The problem is that if the person doesn't develop with a blood clot, then the medical care is required, otherwise this can lead to death.

1. The breathing cycle involves inhalation and exhalation of air due to alternate expansion and contraction of thoracic cavity. Thus it is a rhythmic process. But exchange of gases is a continuous process as it takes place between the blood and each and every cell, by diffusion.

2. The blood clots if conducting tubes of a circulatory system develops a leak. The platelets will increase, which will minimize the leakage. ... The problem is that if the person doesn't develop with a blood clot, then the medical care is required, otherwise this can lead to death.

its the answer...
