During breathing, what happens when there is a decrease of pressure in the thoracic cavity?
Vaselesa [24]
This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.

Answer:

Calcitonin- reduce blood calcium level

Parathyroid hormone- Raise blood calcium level

Explanation:

The thyroid gland is an endocrine gland which secrete its hormone in the blood directly. Both calcitonin and parathyroid hormone are released by the thyroid gland. Parathyroid hormone is released when the blood calcium level is low.

Parathyroid hormone increases the blood calcium level by osteoclast stimulation which releases calcium from bones and increases blood calcium level. Calcitonin is antagonistic to parathyroid hormone and it  reduce the blood calcium level in the blood by stimulating the activity of osteoblast.

In plant cells :-

Anaerobic respiration took place in absence of oxygen and incase of plants it's more much harmful for plants as not in the case of muscles.
