This module explores the chemical building blocks that make up all living organisms. Learners study essential biomolecules such as carbohydrates, proteins, lipids, and nucleic acids, and how they support life processes. It also explains how chemical reactions inside cells drive biological functions.

• Focuses on the structure and function of the cell as the basic unit of life. This module examines organelles such as the nucleus, mitochondria, and ribosomes, explaining how each contributes to energy production, growth, and cellular maintenance.

• Introduces the process of cell division, particularly mitosis, which allows growth, repair, and replacement of cells. Learners explore the stages of division and how genetic material is accurately copied and distributed.

• This module explains how DNA replication ensures genetic continuity from one cell to another. It also covers metabolism, including how cells convert nutrients into energy required for survival and function.

• Examines how cells organize into tissues with specialised roles. The module covers epithelial, connective, muscular, and nervous tissues, highlighting how each type supports the structure and function of organs.

• Focuses on the skin as the body’s largest organ and first line of defence. It explains its layered structure, protective functions, role in temperature regulation, and sensory perception.

• Explores the structure of bones, joints, and cartilage. Learners understand how the skeletal system provides support, enables movement, produces blood cells, and protects vital organs.

• Covers the three types of muscle tissue—skeletal, smooth, and cardiac. The module explains how muscles contract and work with bones to produce movement and maintain posture.

• Examines muscle fibres at a microscopic level, focusing on how actin and myosin interact during contraction. It explains how muscle strength and movement are generated.

• Introduces the nervous system as the body’s communication network. Learners explore how neurons transmit electrical signals to control movement, sensation, and internal body functions.

• Focuses on the structure and function of the brain, including major regions such as the cerebrum, cerebellum, and brainstem. It explains how the brain controls thinking, memory, and coordination.

• Explores how the spinal cord connects the brain to the body. It explains how spinal nerves transmit sensory and motor signals, enabling reflexes and voluntary movement.

• Covers involuntary functions controlled by the autonomic nervous system, such as heart rate and digestion. It also explains cranial nerves and their roles in sensory and motor control.

• Explains how the eye captures light and converts it into electrical signals. The module describes visual processing from the retina to the brain and how vision is formed.

• Focuses on how sound waves are detected and processed by the ear. It also explains the vestibular system responsible for balance and spatial orientation.

• Explores how the brain encodes, stores, and retrieves information. It examines short-term and long-term memory and their role in learning and cognition.

• Covers how the body detects external stimuli through the five senses. The module explains sensory receptors and how the brain interprets sensory input.

• Explains the structure and function of the heart and blood vessels. It focuses on blood circulation, oxygen transport, and maintaining homeostasis in the body.

• Examines the components of blood, including red blood cells, white blood cells, platelets, and plasma. It explains their roles in oxygen transport, immunity, and clotting.

• Focuses on the lymphatic system and its role in maintaining fluid balance and immune defence. It explains how lymph nodes filter harmful substances from the body.

• Explores how the immune system protects the body from pathogens. It covers innate and adaptive immunity and how the body responds to infections.

• Explains how food is broken down into nutrients through mechanical and chemical digestion. It covers organs such as the stomach, intestines, liver, and pancreas.

• Focuses on how oxygen is taken into the body and carbon dioxide is removed. It explains gas exchange in the lungs and the role of the respiratory tract.

• Explores how the kidneys filter waste products from the blood. It explains urine formation and the body’s regulation of water and electrolyte balance.

• Covers the structure and function of male reproductive organs. It explains sperm production, hormone regulation, and reproductive processes.

• Explores the female reproductive system, including ovulation, menstrual cycle, and hormonal regulation. It also explains reproduction and pregnancy processes.
