Human Anatomy - Cardiovascular and Digestive Systems

Cardiovascular System

• Comprises blood, heart, and blood vessels
• Pumps blood throughout the body
• Responsible for carrying oxygen and nutrients to cells and removing waste products
• Blood components help defend against disease and repair damages

Digestive System

• Consists of mouth, pharynx, oesophagus, stomach, small and large intestine, anus, and accessory organs
• Accessory organs include salivary glands, liver, gallbladder, and pancreas
• Performs physical and chemical breakdown of food
• Absorbs nutrients into the bloodstream
• Eliminates solid wastes from the body

Integumentary System

• Comprises skin and its structures such as hair, nails, sweat glands, and oil glands
• Protects the body from external damage
• Regulates body temperature
• Eliminates some waste products through sweating
• Helps in the production of Vitamin D
• Detects sensations such as touch, pressure, and temperature

Lymphatic System and Immunology

• Consists of lymphatic fluid and vessels, spleen, thymus, lymph nodes, and tonsils
• Plays a crucial role in immune function and defending against disease
