Why and how does blood pressure change during steady state exercise?
When you exercise, you need more energy, in order for our muscles cells to function. So more aerobic respiration occurs to provide our cells with oxygen. Oxygen is transferred through blood. So if our heart rate and breathing rate both increase in order to provide our muscles with oxygenated blood, blood pressure increases as well because it transfers oxygen quicker. However this happens during the steady state exercise. After this exercise blood pressure returns to the normal levels of each person.
Asked in Urinary System
How many filters in the kidney what is there function?
There are millions of filters in the kidney, called 'nephrons'. Their job is to filter what will become urine, and is a part of the body's water regulation system. If you are sweating lots from exercise, and your body needs water, your nephrons will reduce the amount of water leaving the body in your urine. When this happens, your urine should be more concentrated, and will be a yellow colour. When you have had lots of water, you urinate more to get rid of the water, as your kidney is regulation the water to keep it at a steady level.

Stroke volume during steady state exercise?
Stroke volume: Stroke volume is the amount of blood ejected per beat from left ventricle and measured in ml/beat. Stroke volume to its highest during sub maximal exercise and doesn't increase during maximal exercise. The greatest increase of stroke volume increases in the transition from rest to moderate exercise, during maximal exercise stroke volume doesn't go over its peak of 120 - 140 per minute Starling's law states that the stroke volume is limited towards the venous return, of which is the amount of the blood that is available to enter the left atrium and pass to the left ventricle

What happens to blood pressure during steady state exercise?
Before you read what happens to blood pressure (BP) you should understand what steady state (also called steady rate) exercise is. Steady state during exercise is the balance between the energy that the working muscles need and the amount of ATP (energy) supplied by aerobic metabolism (aerobic = with oxygen). So, energy needed is matched with energy supplied. At this point there is no accumulation of lactate in the blood (lactate is the product of anaerobic glycolysis, which is the partial breakdown of glucose without oxygen present). You can achieve many levels of steady state exercise. At the onset of exercise or when you increase the intensity your BP rises for a few reasons. First, heart rate and stroke volume (amount of blood ejected from the heart per beat) increase because hormones epinephrine (adrenaline) and norepinephrine (noradrenaline) get released. These cause the heart to beat faster and harder. This pumps more blood out of the heart and into your vasculature system (arteries and veins). *Ex. When you turn the hose on higher, more water comes out and faster, and the hose swells, which is the increase in BP. Second, as your muscles contract they squeeze against the veins (arteries take blood away from the heart, veins bring it back) and this causes momentary but significant increases in blood pressure. Typically it is mainly your systolic blood pressure (pressure in the arteries as your heart is pumping blood out) that rises and not so much diastolic pressure (pressure during the relaxation of the heart as it fills for the next contraction or beat). So basically to answer your question quicker, it rises to maintain the Mean Arterial Pressure set point.

Asked in Health, Exercise, Cardiovascular Health
Cardiovascular drift during steady state exercise?
Cardiocascular drift refers to the upward drift in heart rate and consequential downward drift in stroke volume (amount of blood pumped by the heart with each beat). This phenomenon occurs during prolonged steady-state exercise, particularly in the heat, and is due to the influence of increasing core temperature on dehydration and reduced plasma volume. Because HR increases and SV decreases, total cardiac output (amount of blood pumped per min- HR X SV) remains the same. However, one must still exercise at a lesser intesnity to avoid fatigue- near maximal heart rates are often observed during such occasions.

How much exercise should you get daily to keep a steady weight?
Asked in Biology
What is the type of fermentation that occurs in muscles during rapid exercise?
Lactic Acid Fermentation occurs upon vigorous exercise. This happens because the body is unable to supply sufficient oxygen to the tissues. In lactic acid fermentation first glycolysis takes place and one molecule of glucose is broken to two molecules of pyruvic acid. Then pyruvic acid is turned into lactic acid and a steady amount of ATP is supplied. This process can only supply energy for a short time.

What happens to thermoregulation during steady state exercise?
As we begin to take part in exercise multiple muscle groups begin contracting in order for the running action to take place, these are more contractions than you experience when not exercising, this can cause excess heat to be generated, this heat then travels from the muscle fibers to the skin, this also then generates sweating to take place this is a process called vasodilation. capillaries near the surface of the skin will increase in size to increase blood flow and assist the removal of heat from the body, Because of this when taking part exercise the face may turn red Tasha Webster

Energy system response to steady state exercise?
As your body enters 'steady state' exercise it responds by recruiting the aerobic enery system. This system operates at a low intensity for long time durations and uses O2 as well as fats and CH02 to produce ATP. As the intensity is low, this energy system is able to keep up with the demands of 02 consumption.
