Human Body Systems

Respiratory System

• Allows for gas exchange, taking in oxygen and releasing carbon dioxide

• Pumps blood throughout the body

• Digests food and absorbs nutrients

• Regulates body temperature

Excretory System

• Remove waste products and excess substances from the body

• Produce hormones that regulate metabolism

• Transport oxygen to the body's tissues

• Digest food and absorb nutrients

Nervous System

• Coordinates and controls voluntary and involuntary actions in the body

• Regulates blood circulation and respiration

• Produces hormones for growth and metabolism

• Facilitates digestion and nutrient absorption

Circulatory System

• Circulates blood throughout the body, delivering oxygen and nutrients to tissues and removing carbon dioxide and waste

• Regulates body temperature and fluid balance

• Produces hormones that control metabolism

• Filters and removes toxins from the blood

Immune System

• Protect the body from harmful substances and pathogens, such as viruses, bacteria, fungi, and parasites.

• Regulate body temperature and maintain homeostasis.

• Facilitate the exchange of gases in the lungs.

• Aid in the digestion of food and absorption of nutrients.

Reproductive System

• Regulates hormones and produce offspring.

• Filters waste and regulates water balance.

• Transports oxygen and nutrients to cells.

• Protects the body from infections and diseases.

Musculoskeletal System

• Providing the body with structure and the means for movement

• Regulating body temperature and metabolism

• Transporting oxygen and nutrients throughout the body

• Protecting internal organs from injury

Digestive System

• Breaks down food, absorbs nutrients, and eliminates waste

• Produces hormones that regulate metabolism

• Filters toxins from the blood

• Stores bile for digestion
