4th Quarter Flashcards
-primary function is to facilitate the exchange of oxygen and carbon dioxide between the blood and the air
-occurs in the alveoli of the lungs, tiny air sacs surrounded by capillaries.
Other Functions:
Helps regulate blood pH.
Aids in vocalization.
Protects against inhaled pathogens
Respiratory System
-delivers oxygen, nutrients, hormones, and immune cells to tissues
•Removes carbon dioxide and metabolic wastes
•Helps regulate body temperature
•Maintains blood pressure
Circulatory System
•Breaks down food into smaller molecules that can be absorbed into the bloodstream
•Absorbs water and electrolytes
• Waste Elimination: Eliminates undigested food and other waste products
•Houses a large population of microbes that aid in digestion and immune function
Digestive System
•Acts as a barrier against pathogens, UV radiation, and physical damage.
•Prevents water loss.
•Sensory Perception
•Contains sensory receptors for touch, temperature, and pain.
•Helps regulate body temperature through sweating and blood flow.
•Vitamin D synthesis.
Integumentary System
•Provides a framework for the body.
•Protects internal organs.
•Works with the muscular system to enable movement.
•Bone marrow produces red and white blood cells
•Stores calcium and other minerals.
Skeletal System
•Enables voluntary and involuntary movements.
•Maintains body posture.
•Produces heat through muscle contraction.
Muscular System
•Transmits signals throughout the body.
•Coordinates bodily functions.
•Processes sensory information from internal and external environments.
•Enables thought, memory, and learning.
Nervous System
•Secretes hormones that regulate various bodily functions, including metabolism, growth, and reproduction.
•Plays a large role in maintaining the body’s homeostatic balance.
Endocrine System
•Filters waste products from the blood.
•Eliminates urine. Fluid and Electrolyte Balance:
•Regulates fluid and electrolyte balance.
•Blood pressure regulation
Excretory System
•Produces sperm and eggs.
•Produces sex hormones.
•Offspring Development:
•Provides a site for fertilization and fetal development (female).
Reproductive System
•Filters lymph fluid and fights infection.
•Transports immune cells.
•Returns excess fluid to the bloodstream.
•Absorbs fats from the digestive
Lymphatic System
