Thick, muscular walls to support high pressure while carrying blood away from the heart
What are arteries?
Primary Organs of Respiration
What are the Lungs?
Controls involuntary functions such as heart rate and digestion
What is the Autonomic Nervous System?
These carry oxygenated blood to the body tissues
What are Systemic Arteries?
Maintains cell shape and facilitates cell movement
What is the Cytoskeleton?
Thinner walls with valves to prevent backflow while carrying blood back to the heart.
What are Veins?
Contracts to increase lung volume during inhalation
What is the Diaphragm?
Chemical messengers that transmit signals between neurons
What are Neurotransmitters?
The airway from larynx to bronchi
What is the Trachea?
Contains genetic material and directs cell activities
What is the Nucleus?
Circulation of blood between the heart and lungs
What is Pulmonary Circulation?
What is Gas Exchange?
Transmits sensory information to the Central Nervous System
What is the Somatic Nervous System?
Composed of two or more tissues and work together to perform a specific function.
What is an Organ?
Process of breaking down glucose to release energy
Diaphragm relaxes causing the chest to contract
What is Exhalation?
Rapid, involuntary responses to stimuli
What are Reflexes?
Covers body surfaces and lines organs
