Nitric oxide and epinephrine ________. A. both regulate blood flow B. both function as steroid hormones C. bind the same recepto

charle [14.2K]

Nitric oxide and epinephrine both regulate the blood flow.

<h3>Neurotransmitters : </h3>

it is known as body's chemical messenger. it transmit signals from neuron to muscle and neuron to neuron.

Types of neurotransmitters are excitatory neurotransmitters, inhibitory and modulatory neurotransmitters.

Common neurotransmitters disease are Parkinson's disease, Alzheimer's disease, and depression.

there are other type of neurotransmitters found in the cell. they are Amino acid , peptides, monoamines, purines, gaso-transmitters and acetylcholine.

these are only created in the neuron cells.

neurotransmitters level can only increase when we take vitamines like vitamin B6 and minerals like Iron, niacin, folate.

The level also increases when we eat more protein, get enough sleep,meditate and exercise regularly.

<h3>Epinephrine:</h3>

it is a type of neurotransmitters.

it is used for emergency treatment of severe allergic reactions due to insect bites or medicines, foods, etc.

it increases both systolic and diastolic blood pressure.

epinephrine also known as adrenaline. it is called as emergency hormone.

it increases the quantity of blood pumped through heart.

in situation like fatigue, shock,fear , excitement,and danger the secretion of adrenaline increases.

What is the correct flow of depolarization in the heart?

natita [175]

Answer: The correct answer is option c.

Explanation:

Cardiac conduction system is formed by specialized cardiac muscle cells which enable the heart to contract in coordinated fashion.

The main component of this system are:

Sinoatrial node
Atrioventricular node
Bundle of His
Branched bundle
Punkinje fibers

SA node consists of cells known as pacemaker cells. These cells spontaneously generate action potentials which lead to the contraction of atria.

These potentials are then passed to AV node which relay them to bundle of His. These bundles are branched into right and left bundle which ultimately transfer these potentials to Purkinje fibers.

The potentials from these fibers lead to the contraction of ventricles.

High blood pressure occurs when there is too much blood flowing through the blood vessels at one time. By changing the amount of

san4es73 [151]

Answer: More water will be transferred from the nephron

The excretory system is the system in the organisms body which allows the excretion of unwanted waste metabolites from the body like nitrogenous wastes like ammonia, salts and excess of water. Water is the chief ingredient of blood it decreases the viscosity of blood and prevents it's clotting.

In the case of hypertension or high blood pressure the excretory system plays an important role by expelling more amount of water out of the body. Therefore, more amount of water will be transferred from the nephron to the urinary bladder. It is an internal control of the body. It increases the urge to urinate to expel the water and preventing the ill effects of high blood pressure.
