Comprehensive Human Body Systems: Functions, Organs, and Homeostasis

What are the 11 body systems?

Integumentary, Muscular, Skeletal, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive.

What is the primary function of the muscular system?

To facilitate body movements, maintain posture, stabilize joints, and produce energy.

How many bones are in the human skeletal system?

206 bones.

What are the functions of the skeletal system?

Strengthens and supports the body, protects internal organs, provides attachments for muscles, produces blood cells, and stores minerals.

What is the main function of the cardiovascular system?

To transport nutrients and oxygen to body tissues and remove metabolic wastes.

What is the main function of the respiratory system?

To provide passages for gaseous exchange and supply oxygen for energy production.

What does the integumentary system include?

Skin and hair.

What is the function of the integumentary system?

To protect organs from germs and viruses and minimize water loss.

What organs are part of the lymphatic system?

Spleen and thymus.

What is the role of the nervous system?

To receive information from body organs and direct their operation as a team.

What does the endocrine system control?

Homeostasis by releasing hormones that regulate chemical reactions in the body.

What organs are included in the urinary system?

Kidneys and bladder.

What is the function of the urinary system?

To maintain water and chemical balance in the blood and filter waste products.

What organs are part of the reproductive system?

Ovaries and testes.

What is the primary function of the reproductive system?

To ensure the survival of the species by creating new organisms.

How do the digestive and respiratory systems interact?

The digestive system processes food into glucose, while the respiratory system provides oxygen needed to metabolize that glucose.

What is homeostasis?

The maintenance of a constant internal environment in the body.

What conditions must be controlled for homeostasis?

Body temperature, water content, carbon dioxide level, and blood sugar level.

How do body systems cooperate to maintain homeostasis?

They work together to regulate internal conditions, ensuring all systems function effectively.
