Front

What is the role of the respiratory system during physical exertion?

Back

The respiratory system increases the breathing rate to supply more oxygen to the blood, which is essential for muscle function during physical activity.

Front

How does the circulatory system respond to increased physical activity?

Back

The circulatory system increases blood pressure and heart rate to deliver more oxygen and nutrients to the muscles.

Front

What is the function of white blood cells in the immune response?

Back

White blood cells help to identify and eliminate pathogens, such as bacteria and viruses, at the site of an injury.

Front

What is the relationship between the nervous system and the endocrine system during a stress response?

Back

The nervous system triggers the endocrine system to release hormones, such as adrenaline, which prepare the body for a 'fight or flight' response.

Front

Define vasodilation and its effect on body temperature regulation.

Back

Vasodilation is the widening of blood vessels, which increases blood flow to the skin and helps to lower body temperature.

Front

Define vasoconstriction and its effect on body temperature regulation.

Back

Vasoconstriction is the narrowing of blood vessels, which reduces blood flow to the skin and helps to conserve body heat.

Front

What is an internal feedback mechanism?

Back

An internal feedback mechanism is a process that helps maintain homeostasis by regulating physiological functions based on internal conditions.

Front

How do the skeletal and muscular systems work together during movement?

Back

The skeletal system provides structure and support, while the muscular system contracts to produce movement.

Front

What is the role of hormones in the body's response to injury?

Back

Hormones can regulate various physiological responses, including inflammation and healing processes, after an injury.

Front

Explain the concept of homeostasis.

Back

Homeostasis is the ability of the body to maintain a stable internal environment despite changes in external conditions.
