- the nephron uses four mechanism to convert blood into urine.
- filteration
- excreation
- secration
- reabsorption
Explanation:

When blood pressure receptors sense a loss of blood pressure, they decrease their firing rate to the medulla.
Baroreceptors or blood pressure receptors are the receptors present in the carotid sinus i.e. the bifurcation of the external and internal carotids and in the aortic arches.
They are important to maintain the blood pressure in the body. whenever there is a change in the blood pressure they send information to the brain so that the pressure can be maintained.
They are able to sense the pressure change for only short period pressure change. When the pressure change occurs over a long period of time they get adjusted to it.
