What human body systems means

You learn how the main organs work together to keep the body alive and healthy. This helps you answer questions on how blood moves, how oxygen enters the body, and how waste is removed.

What you will practise

  • Name the organ that pumps blood through the body.
  • Identify where gas exchange takes place in the lungs.
  • Match each organ to its main job in the body.
  • Choose the correct organ for removing waste from blood.

Before you start

You should already know the names of basic body parts and simple cell ideas. It also helps if you can read short science questions and match words to functions.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Which organ pumps blood around the body?

  • Lungs
  • Heart
  • Liver
  • Kidneys
Answer: Heart

Working: The heart is a muscular pump that circulates blood.

Common mistakes to avoid

  • Confusing the heart with the lungs. Remember the heart pumps blood, while the lungs help with breathing.
  • Picking the whole lung instead of the alveoli for gas exchange. Gas exchange happens in the tiny air sacs.
  • Mixing up the kidneys with the liver. The kidneys filter blood and make urine.
  • Answering with a body system name when the question asks for one organ. Read carefully for the exact part needed.

Curriculum and exam alignment

Ghana GES Basic 7 to 9 syllabusBECE

In Junior High School, this usually comes in the human biology section as part of the study of organs and body systems. It supports BECE revision by building clear knowledge of organ functions and common science terms.

Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
