Human Body Features & Health Conditions: Revision Sheet

1. 📌 Essentials

• The human body is characterized by facial features, internal organs, skin marks, and body parts.
• Key facial features: cheekbone, eyebrow, eyelid, lips, nose, jaw, beard.
• Internal organs include liver, lungs, kidneys, intestines, bladder, appendix.
• Circulatory system: arteries (oxygen blood), veins (deoxygenated).
• Skin marks: spots, moles, birth marks, warts, freckles, wrinkles.
• Common diseases: flu, measles, chickenpox, mumps, hepatitis, AIDS, cancer, diabetes.
• Symptoms: fever, nausea, rash, inflammation, pain types.
• Contagiousness influences disease spread: contagious, highly contagious, epidemic.
• Medical procedures: surgery, operation.
• Pain: sharp, throbbing, steady, nagging, agonizing.

2. 🧩 Key Structures & Components

• Facial features — cheekbones, eyebrows, eyelids, eyelashes, lips, nose, jaw, beard.
• Skin marks & lesions — spots, moles, birth marks, warts, freckles, wrinkles.
• Head & skull — skull, temples, cheekbones, brow, hair.
• Internal organs — liver, lungs, kidneys, intestines, bladder, appendix.
• Circulatory system — arteries (carry oxygen-rich blood), veins (carry oxygen-poor blood).
• Body parts — navel, waist, hips, bottom, belly, breasts, back, limbs.
• Symptoms & signs — pain, rash, inflammation, fever.
• Diseases & conditions — flu, measles, hepatitis, AIDS, cancer, diabetes.

3. 🔬 Functions, Mechanisms & Relationships

• Facial features help in identification and expression.
• Skin marks can indicate age, health, or skin conditions.
• Internal organs work hierarchically: liver detoxifies, lungs oxygenate blood, kidneys filter waste.
• Circulatory system distributes oxygen and nutrients via arteries and veins.
• Pain signals indicate tissue damage or disease.
• Diseases spread through contact, contaminated objects, or vectors.
• Symptoms guide diagnosis: fever suggests infection, rash indicates skin issues.
• Medical procedures like surgery treat internal or external health issues.
• Contagious diseases spread rapidly, requiring isolation and hygiene.

4. Comparative Table: Circulatory System

Item	Key Features	Notes / Differences
Arteries	Carry oxygenated blood from heart to body	Thick walls, high pressure
Veins	Carry deoxygenated blood back to heart	Valves prevent backflow, thinner walls

6. ⚠️ High-Yield Pitfalls & Confusions

• Confusing moles with warts; moles are pigmented, warts are viral.
• Mistaking wrinkles as skin disease; they are signs of aging.
• Overlooking contagiousness in infectious diseases.
• Confusing arteries (oxygenated) with veins (deoxygenated).
• Misidentifying internal organs; e.g., liver vs. kidneys.
• Assuming all skin marks are harmful; many are benign.
• Ignoring pain types; sharp pain often indicates acute injury.
• Confusing fever with other symptoms like chills or rash.

7. ✅ Final Exam Checklist

• Recall major diseases: flu, measles, hepatitis, AIDS, cancer.
• Understand disease transmission and prevention.
• Know basic medical procedures: surgery, operation.
• Identify signs of internal and external health issues.
• Understand the hierarchy of head bones and facial structures.
• Recognize the significance of skin marks in diagnosis.
• Be aware of common health terms: contagious, epidemic, outbreak.
• Know the body parts involved in health assessment.
• Understand the relationship between symptoms and diseases.
