Explanation:

Each body system's function and key organs/hormones are based on core human biology concepts, focusing on core regulatory, transport, structural, and metabolic roles.

Answer:

1. Nervous System - Coordinates body's electrical/chemical signals

Major Organs - Brain and Spinal Cord

1. Reproductive System - Produce offspring and sex hormones

Major Organ in Males - Testes which produce the hormone Testosterone
Major Organ in females - Ovaries which produce the hormone Estrogen

1. Endocrine System - Regulates body via chemical hormones

Major Structures are organs called Glands and chemicals called Hormones

1. Circulatory System - Transports blood, nutrients, gases, and wastes

Major Organs - Heart to pump blood, Arteries to move blood away, Veins to move blood towards the heart, and Capillaries to exchange $\text{O}_2$ and $\text{CO}_2$

1. Respiratory System - Facilitates gas exchange ($\text{O}_2$ in, $\text{CO}_2$ out)

Major organs - Nose/Mouth take in air, Trachea (windpipe) and Alveoli (air sacks)

1. Muscular System - Enables body movement and structure support

3 major organ structures - Skeletal muscles to help the body move, Smooth muscles form hollow organs, and Cardiac muscles that make up the heart.

1. Skeletal System- Provides structure, protection, and mineral storage

The one organ is Bones

1. Digestive System - Breaks down food and absorbs nutrients

Major Organs - Stomach, Small Intestine, and Large Intestine

1. Excretory System - Removes waste products from the body

Major Organs - Kidneys and Bladder
