Cardiac output is the volume of blood that your heart pumps per minute. With it being increased, it means that there is an increase in volume of blood that your heart pumps around the body.

Hope this helps with whatever you're doing - like PE BTEC...

Is cardiovascular output increased by aerobic exercise?

Yes. Cardiac output is increased by any form of aerobic exercise.

What increases blood pressure?

weight, alcohol intake, whether you smoke or not, stress increased peripheral resistance,increased force of cardiac contraction, and increased cardiac output

Would an increase in contractility cause an increase to cardiac output?

Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.

Which of the following would cause the greatest increase in cardiac output?

Increased heart rate and increased stroke volume

Which of the following would increase cardiac output to the greatest extent?

increased heart rate and increased stroke volume.

How does an increased or decreased cardiac output impact the body?

A decrease or increase of cardiac output in the body can result to several health problems depending on the body's health conditions. A stroke is prevalent if there is an increase of cardiac output that cannot be handled by the system. Lack of oxygen in the brain is an effect of a decrease cardiac output on the other hand.

Increased Cardiac Output?

the amound of blood pumped by the heart in a minute by cai vickers

Does blood volume influence blood pressure?

Increasing the blood volume will increase the return to the heart which will increase the cardiac output. Increased cardiac output increase s blood pressure.

What are the effects on the circulatory system when there is increased cardiac output?

When the cardiac output increases, the arterial and venous pressure rises as there is increased load on the circulatory system. The pulse rate will increase and the blood pressure, especially systolic, will show a rise. The person can have palpitations and sometimes dyspnoea.

Why doesn't diastolic pressure increase after exercise?

Systolic pressure increases during exercise due to increased cardiac output. Diastolic pressure does not depend on cardiac output and will either remain the same or actually decrease.

What are some factors that increase blood pressure?

Increased blood viscosity, increased cardiac output, increased pulse rate, anxiety, fear, physical exercise, Nicotine, and arteriosclerosis

What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?

Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.

Total cardiac output for average adult?

CARDIAC OUTPUT;is the amount of blood ejected from heart.cardiac output=stroke volume multiplied by heart rate.The amount of blood expelled by each contraction of the ventricles is called stroke volumeIt is actually expressed i n litres per min.In general healthy adults at rest,the stroke volume is approximately 70ml and if the heart rate is 72 per mi9n.then cardiac output is 5 l/min.This can be greatly increased to meet the demands of exercise to around 25 l/min. and in athletes up to 35 l/min.This increase during exercise is called the CARDIAC RESERVE.when increased blood supply is needed to meet increased tissue reqirements of oxygen and nutrients ,heart rate and stroke volume can be increased.

If resting cardiac output is six liters and maximum exercise cardiac output is sixteen liters what is the cardiac reserve?

10 liters

What compensations does the body have to do to defend cardiac output if you hemorrhage?

what compensations does the body have to do to defend cardiac output

How is cardiac output measured?

Cardiac output is measured by techniques such as the Fick Pickle and Dilution methods. Other methods of measuring Cardiac output include Doppler ultrasound and Echocardiography.

Why does your heart need to pump more quickly during exercise?

During exercise your body requires up to 10 times the ammount of oxygen that you need at rest. You can only extract about 3 times as much O2 from the blood as at rest, so you must increase your cardiac output by about 3 times too. increased cardiac output = increased cardiac rate. (NOT the other way around)

What is the percentage of the cardiac output delivered to the kidneys?

kidneys receive 20-25% of total cardiac output20-20%blood of course15%they receive 21% of the cardiac output

What effects cardiac output during the first few stages of exercise?

Cardiac Output is computed as your heart rate times your stroke volume (volume of blood ejected from the heart each beat). The main contributor when exercising is an acceleration in heart rate. Stroke volume can be increased, but only by prolonged aerobic training. To answer your Q, HR as has the main effect on cardiac output during the first stages of exercise.**The first few stages of cardiac exercise will 'affect' cardiac output, not 'effect' it. If you don't know the difference between the two, you should not be asking a question such as this...

What is cardiac output?

Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV.

Why do the arterioles have resistance?

Arterioles can increase and decrease their resistance in response to changes in cardiac output in order to maintain blood pressure. Increased cardiac output will cause arterioles to correspondingly decrease their resistance (thus increasing their compliance) so blood pressure remains unchanged.

Does exercise Change in cardiac output or in peripheral resistance?

Both, peripheral resistance decreases and cardiac output increases.

How would hemorrhage effect cardiac output?

It would decrease blood pressure due to a change in cardiac output.

What does cardiac output do if the heart rate decreases?

Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.

How does an increase of cardiac ouput help the athlete during exercise?

An increase in cardiac output provides increased oxygen to working muscles in an exercising athlete. It also provides more energy in the form of nutrients.
