What are the functions of the skin, the organs of the nervous system, and the effects of alcohol on it, as well as the effects of stress?

Let's go through the questions from the image.

QUESTION 4: HYGIENE

4.1) Label the parts of the skin in the diagram below:

1. Epidermis
2. Dermis
3. Subcutaneous tissue (Hypodermis)

4.2) Give two importance of the skin.

1. Protection: The skin acts as a barrier against pathogens, UV radiation, and physical injury.
2. Temperature Regulation: It helps maintain body temperature through sweating and by controlling blood flow to the surface.

QUESTION 5: Nervous System

5.1) For each nervous system, identify the organ in control from the list (List of organs - Brain, Heart, Oesophagus, and -Spinal Cord).

Central Nervous System	Peripheral Nervous System
Brain	Heart
Spinal Cord	Oesophagus

5.2) Give three effects of alcohol on the nervous system.

1. Impaired Coordination: Alcohol affects the cerebellum, leading to difficulty with balance and motor control.
2. Slowed Reaction Time: It depresses the central nervous system, slowing down the processing of information and responses.
3. Impaired Judgment: Alcohol affects the frontal lobe, leading to poor decision-making and reduced inhibitions.

QUESTION 6: Stress

6.1) State two effects of stress on Mr. Paul.

1. Physical Fatigue: Prolonged stress can lead to exhaustion, headaches, and muscle tension.
2. Reduced Concentration: Stress can make it difficult to focus, leading to errors and decreased productivity.

6.2) Give three ways Mr. Paul could reduce the effect of stress at his work post.

1. Prioritize Tasks: Organize work by importance and urgency to manage workload effectively.
2. Take Short Breaks: Step away from the work area periodically to rest and clear his mind.
3. Communicate with Management: Discuss workload and deadlines with supervisors to seek support or adjustments.

QUESTION 7: SAFETY

7.1) Give two importance of a pictogram in a workshop.

1. Quick Hazard Identification: Pictograms provide a universal, visual warning of potential dangers (e.g., flammable, corrosive) that can be understood quickly, regardless of language.
2. Enhanced Safety Awareness: They serve as constant reminders of safety precautions, promoting a safer working environment and reducing the risk of accidents.
