During exercise, a number of changes occur to maximise the body's oxygen intake. Firstly our heart rate/ pulse increases. This is due to the heart beating much faster and more forcefully to pump blood faster around the body.
Our breathing rate increases to intake more oxygen and exhale more CO2.
The smooth muscle in our trachea and bronchi relaxes to increase the lumen size thus making breathing easier. Adrenaline may also be released leading further amplifying these changes as well as reducing blood flow to the gut and thus peristalsis occurs at a much slower rate.
Also when we exercise we respire more, producing heat, which must be expelled. This may be done through sweating. Another physiological change that occurs is vasodilation of arterioles closer to the skin to allow more blood to flow closer to the skin, allowing more heat to radiate out.
Answer:
Peripheral vasodilators
Explanation:
Peripheral dilators are a form of vasodilators that are involved in the dilation of the most distal parts of the vascular system such as the venules and arterioles. It does this by relaxing the smooth muscle of the blood vessels that are wide open, therefore making it easier for the heart to pump blood through blood vessels and also the whole body.
In the treatment of hypertension, the peripheral dilators lower blood pressure by decreasing the total peripheral resistance of the arteries. In addition to the treatment of hypertension, they are also used in the treatment of heart failure and acute myocardial infarction.
An example is isoxsuprine.
DNA and RNA (Deoxyribonucleic Acid Ribonucleic Acid)
Answer:The heart isn't the only muscle to benefit from regular exercise. The other muscles in your body enjoy exercise too.

Explanation:</h3>
When you use your muscles, they become stronger. Strong muscles are also a plus because they support your joints and help prevent injuries
Minerals, unable to move up to the leaves, are accumulating in the root, which causes water to rush in due to osmosis.
