Testing paper 1- GCSE PE Revision Live

The video tutorial covers key topics for an upcoming AQA exam, focusing on the musculoskeletal system, types of muscular contractions, blood vessels, and the mechanics of breathing. It explains how muscles work in antagonistic pairs, the differences between isotonic and isometric contractions, and the structure and function of arteries, veins, and capillaries. The tutorial also details the process of breathing, including the roles of the diaphragm and intercostal muscles.

What is the primary focus of the exam topics discussed in the introduction?

• The musculoskeletal system

• The digestive system

• The cardiovascular system

• The nervous system

In an antagonistic muscle pair, what is the role of the agonist muscle?

• It stabilizes the joint

• It is responsible for the primary movement

• It opposes the movement

• It relaxes during movement

Which type of muscle contraction involves the muscle lengthening under tension?

• Concentric contraction

• Isometric contraction

• Static contraction

• Eccentric contraction

What is the main function of arteries in the circulatory system?

• To carry blood towards the heart

• To exchange gases with tissues

• To carry blood away from the heart

• To store blood

Which blood vessel type is primarily involved in gaseous exchange?

• Lymphatic vessels

• Capillaries

• Veins

• Arteries

What happens to blood vessels during vasodilation?

• They constrict and reduce blood flow

• They dilate and increase blood flow

• They become rigid and immobile

• They collapse and stop blood flow

During exercise, how is blood flow adjusted to meet the demands of active muscles?

• By decreasing blood pressure

• Through vasodilation of blood vessels

• Through vasoconstriction of blood vessels

• By increasing heart rate only

What is the role of the diaphragm during inspiration?

• It contracts and moves upwards

• It relaxes and moves downwards

• It contracts and flattens

• It relaxes and curves

Which muscles are involved in moving the rib cage during breathing?

• Intercostal muscles

• Deltoid muscles

• Abdominal muscles

• Pectoral muscles

What is the term for the normal volume of air displaced between inhalation and exhalation?

• Inspiratory reserve volume

• Tidal volume

• Expiratory reserve volume

• Residual volume
