Practise MYP Biology questions on 2.4 Systems and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
Which scenario best describes the digestive system's reliance on the circulatory system?
Which of these scenarios best illustrates the concept of 'functional coordination' between the respiratory and circulatory systems?
Which statement best explains the role of the diaphragm within the respiratory system's hierarchy?
What is the primary biological advantage of organs linking their functions to form an organ system?
Which tissue type forms the extremely thin walls of the alveoli to facilitate efficient gas exchange between the lungs and blood?
The blood transporting absorbed nutrients from the small intestine to the rest of the body
The blood producing digestive enzymes to break down proteins in the stomach
The blood providing the physical pressure needed to swallow food
The blood filtering out water from the large intestine to create waste
The lungs expanding while the heart stops beating.
The heart increasing its pump rate when the lungs detect low oxygen levels.
The large intestine absorbing water while the trachea closes.
The stomach releasing acid when the diaphragm contracts.
It is an organ made of muscle tissue that controls the mechanical process of breathing
