How the nervous and endocrine system involve in the human cardiac function?

Explanation

The type of heart in human is myogenic because the heart beat originates form the muscles of the heart.
2. The nervous th nedocrine systems work together with paracrine signals (metabolic activity ) to influence the diameter of the artirioles and alter the blood flow.
The neuronal control is achieved through autonomic nervous system ( sympathetic and parasympathetic). Sympathetic neurons relese nor - epinephrine and adrenal medulla releases epinephrine.
4. The two hormones bind to `beta-` adrenergic receptors and increases the heart rate.
5. The parasympathetic neurons secrete acetylcholine that bnds to muscarinic receptors and decreses the heart beat.
6. Vasopressin and angiotensin II, involved in the regulation of the kidneys, results in vasoconstriction while natriuretc peptide promotes vasodilation.
7. Vagus nerve is a parasympathtic nerve that supplies the atrium especially the SA and the AV nodes.
