A level WJEC How exercise effects the heart

The cardiac control centre is located in which part of the brain

• Medulla Oblongata

• Cerebrum

• Temporal lobe

• Hypothalamus

The nervous system responsible for increasing heart rate is called the ...

These receptors detect changes in the PH in the blood as a result of increases in carbon dioxide and lactic acid

These receptors detect changes in body temperature as a result if heat produced by working muscles

• Barorecptors

• Chemoreceptors

• Proprioceptors

• Thermoreceptors

The contraction of the heart is stimulated by the..

• Sino atrial node

• Atrio ventricular node

• Hypothalamus

• Cerebelum

When exercising you have an increase of blood flow back to the heart. What is the flow of blood back to the heart called?

When exercising there is an increase in venous return, this leads to the cardiac muscle being stretched which increases the force of contraction (like a rubber band being stretched) What is this called?

The nervous system responsible for reducing heart rate is called the ..

The receptors that detect changes in blood pressure are called

The receptors in the muscles that detect movement are called...

• Proprioceptors

• Baroreceptors

• Thermoreceptors

• Chemoreceptors
