Unit Overview

Introduction

This unit provides foundational knowledge of human anatomy and physiology, specifically tailored for nursing and midwifery students. It covers the biological basis of human health and the functioning of the human body, with a focus on systems integration, hormonal processes, nutrition, and fluid balance. The unit also emphasizes the application of anatomical and physiological concepts in clinical and therapeutic environments.

Main Topics

1. Integumentary System

The integumentary system consists of the skin, hair, nails, and associated glands. It serves as the body's first line of defense against environmental hazards and plays a crucial role in homeostasis.

• Key Functions: Protection, sensation, temperature regulation, vitamin D synthesis.

• Components: Epidermis, dermis, hypodermis, sweat glands, sebaceous glands.

• Example: The skin prevents pathogen entry and regulates water loss.

2. Lymphatic System and Immunology

The lymphatic system is essential for fluid balance, immune response, and the absorption of dietary fats. Immunology focuses on the body's defense mechanisms against pathogens.

• Key Functions: Transport of lymph, immune surveillance, removal of interstitial fluid.

• Components: Lymph nodes, lymph vessels, spleen, thymus, tonsils.

• Example: Lymph nodes filter harmful substances and house immune cells.

3. Endocrine System

The endocrine system regulates body functions through hormones secreted by glands. It is vital for growth, metabolism, and homeostasis.

• Key Functions: Hormone production, regulation of metabolism, stress response.

• Components: Pituitary gland, thyroid gland, adrenal glands, pancreas, gonads.

• Example: Insulin from the pancreas regulates blood glucose levels.

4. Digestive System and Nutrition

The digestive system breaks down food, absorbs nutrients, and eliminates waste. Nutrition is the study of how food affects health and body function.

• Key Functions: Digestion, absorption, excretion.

• Components: Mouth, esophagus, stomach, intestines, liver, pancreas.

• Example: The small intestine absorbs nutrients into the bloodstream.

5. Urinary System

The urinary system removes waste products from the blood and regulates fluid and electrolyte balance.

• Key Functions: Filtration of blood, urine formation, regulation of blood pressure.

• Components: Kidneys, ureters, bladder, urethra.

• Example: The kidneys filter toxins and excess ions from the blood.

6. Special Senses

Special senses include vision, hearing, taste, smell, and equilibrium. These senses allow the body to interact with and interpret the environment.

• Key Functions: Sensory perception, balance, communication.

• Components: Eyes, ears, tongue, nose, vestibular system.

• Example: The retina in the eye detects light and sends signals to the brain.

7. Neural Transmission

Neural transmission refers to the process by which nerve cells communicate via electrical and chemical signals.

• Key Functions: Signal conduction, reflexes, integration of sensory and motor information.

• Components: Neurons, synapses, neurotransmitters.

• Example: Acetylcholine is a neurotransmitter involved in muscle contraction.

8. Growth and Development

Growth and development encompass the changes that occur throughout the human lifespan, including cellular growth, differentiation, and aging.

• Key Functions: Cell division, tissue differentiation, maturation.

• Components: Stem cells, growth factors, hormones.

• Example: Growth hormone stimulates bone and muscle growth during childhood.

Key Concepts and Definitions

• Homeostasis: The maintenance of a stable internal environment despite external changes.

• Neurotransmitters: Chemical messengers that transmit signals across synapses between neurons.

• Hormones: Chemical substances produced by endocrine glands that regulate physiological processes.

• Metabolism: The sum of all chemical reactions in the body, including catabolism and anabolism.

Learning Outcomes

• K1: Describe the relationships between body systems and their roles in maintaining homeostasis.

• K2: Describe major changes during growth and development and their impact on health.

• K3: Explain the role of neurotransmitters, their receptors, and their functions.

• S1: Relate homeostasis to physiological processes.

• S2: Connect body systems using a variety of resources and identify their relevance to practice.

• A1-A3: Apply anatomical and physiological concepts to clinical scenarios and demonstrate use of health terminology.

Course Structure and Assessment

• Delivery Mode: Regular semester, with options for standard or blended study.

• Assessment Tasks: Online quizzes, laboratory reports, theory tests, and participation in laboratory sessions.

• Grade Scheme: Graded (HD, D, C, P, MF, F).
