body systems Flashcards
What are the components of the Circulatory System?
Heart, blood vessels (arteries, veins, capillaries), blood
What is the primary function of the Circulatory System?
Transports oxygen, nutrients, and wastes; helps maintain homeostasis
What are the components of the Respiratory System?
Lungs, trachea, bronchi, alveoli
What is the primary function of the Respiratory System?
Facilitates gas exchange (oxygen in, carbon dioxide out)
What are the components of the Digestive System?
Mouth, esophagus, stomach, small intestine, large intestine, liver, pancreas
What is the primary function of the Digestive System?
Breaks down food, absorbs nutrients, eliminates waste
What are the components of the Musculoskeletal System?
Bones, muscles, tendons, ligaments
What is the primary function of the Musculoskeletal System?
Provides structure, movement, and protection for internal organs
What are the components of the Nervous System?
Brain, spinal cord, nerves
What is the primary function of the Nervous System?
Sends electrical signals throughout the body to control and coordinate functions
What are the components of the Excretory (Urinary) System?
Kidneys, ureters, bladder, urethra
What is the primary function of the Excretory (Urinary) System?
Removes waste products and excess substances (e.g., water, salts)
What are the components of the Endocrine System?
Glands (e.g., thyroid, adrenal, pancreas), hormones
What is the primary function of the Endocrine System?
Regulates body functions through hormones (e.g., growth, metabolism, mood)
What are the components of the Immune System?
White blood cells, lymph nodes, spleen, antibodies
What is the primary function of the Immune System?
Protects the body against infection and disease
How do the Circulatory and Respiratory Systems interact?
Oxygen from the lungs enters the blood, and carbon dioxide is removed
How do the Digestive and Circulatory Systems interact?
Nutrients from digested food are absorbed into the bloodstream
How do the Musculoskeletal and Nervous Systems interact?
The brain sends signals to muscles to produce movement
How do the Endocrine and Nervous Systems interact?
The brain controls hormone secretion, which affects various body functions (e.g., stress response)
