ENDOCRINE ORGANS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some cells in the atria of the heart secrete hormones that:
A
Increase calcium uptake by the kidney
B
Decrease digestive processes
C
Decrease blood pressure (BP)
D
Increase heart rate
Explanation: 

Detailed explanation-1: -Atrial naturetic hormone or ANP is a member of a family of peptides that have important roles in regulating blood pressure, most prominently through their activity in the kidney to promote excretion of water and sodium. A majority of ANP is synthesized and secreted from cardiac muscle cells, particularly in the atria.

Detailed explanation-2: -The atrial natriuretic hormone (ANP) is a cardiac hormone which gene and receptors are widely present in the body. Its main function is to lower blood pressure and to control electrolyte homeostasis.

Detailed explanation-3: -Atrial natriuretic peptide (ANP) or atrial natriuretic factor (ANF) is a natriuretic peptide hormone secreted from the cardiac atria that in humans is encoded by the NPPA gene.

Detailed explanation-4: -An atrial natriuretic peptide (ANP) is the hormone that is secreted by the human heart. Brain natriuretic peptide is another hormone produced by the heart which is also called a ventricular natriuretic peptide. This is secreted by the human heart when there an increase in ventricular blood volume.

Detailed explanation-5: -Hormones released by the heart The first, atrial-natriuretic peptide (ANP), is produced by atrial cardiomyocytes, and serves to reduce blood pressure through several mechanisms.
