• Endocrine System

• Digestive System and Nutrition

• Urinary System

• Special Senses

• Neural Transmission

• Growth and Development

Learning Outcomes

Knowledge

• K1: Describe the relationships between the structure of the integumentary, lymphatic, endocrine, urinary, and digestive systems and their roles in bodily functions, including the maintenance of homeostasis.

• K2: Describe the major changes during growth and development across the lifespan and how they relate to health.

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

Skills

• S1: Relate the concept of homeostasis to physiological processes.

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

Application of Knowledge and Skills

• A1: Demonstrate accurate use of health terminology related to human anatomy and physiology for communication in a healthcare environment.

• A2: Make reasoned observations of anatomical and physiological structures or events under normal and abnormal conditions.

• A3: Demonstrate and apply theoretical concepts to simulated scenarios to develop a framework for critical understanding of human anatomy and physiology within practical settings.

Key System Overviews

Integumentary System

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

• Key Functions: Protection, sensation, thermoregulation, vitamin D synthesis.

• Example: The skin acts as a barrier to pathogens and helps prevent dehydration.

Lymphatic System and Immunology

The lymphatic system is a network of vessels and nodes that helps maintain fluid balance and plays a crucial role in immune defense.

• Key Functions: Fluid recovery, immune surveillance, absorption of dietary fats.

• Example: Lymph nodes filter lymph and house lymphocytes that respond to pathogens.

Endocrine System

The endocrine system consists of glands that secrete hormones, which regulate various physiological processes throughout the body.

• Key Functions: Regulation of metabolism, growth, reproduction, and homeostasis.

• Example: The pancreas secretes insulin to regulate blood glucose levels.

Digestive System and Nutrition

The digestive system breaks down food, absorbs nutrients, and eliminates waste. Nutrition refers to the intake and utilization of nutrients necessary for health.

• Key Functions: Digestion, absorption, excretion, nutrient assimilation.

• Example: The small intestine absorbs amino acids and simple sugars into the bloodstream.

Urinary System

The urinary system removes waste products from the blood and maintains water and electrolyte balance.

• Key Functions: Filtration of blood, excretion of waste, regulation of blood pressure and volume.

• Example: The kidneys filter urea from the blood to form urine.

Special Senses

Special senses include vision, hearing, taste, smell, and equilibrium, each associated with specialized organs and neural pathways.

• Key Functions: Sensory perception and processing.

• Example: The retina in the eye detects light and transmits signals to the brain for visual processing.

Neural Transmission

Neural transmission involves the communication of signals between neurons and other cells via neurotransmitters.

• Key Functions: Rapid communication, coordination of body functions, response to stimuli.

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

Growth and Development

Growth and development encompass the physical and functional changes that occur from conception through adulthood and aging.

• Key Concepts: Cell division, differentiation, hormonal regulation, aging processes.

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

Homeostasis

Homeostasis is the maintenance of a stable internal environment despite external changes. It is essential for normal physiological function and survival.

• Definition: The process by which biological systems maintain stability while adjusting to changing external conditions.

• Example: Regulation of body temperature through sweating or shivering.
