Endocrine System
What is the Endocrine System?
The Endocrine System is your body's chemical messenger system. (Made of glands and organs that produce and release hormones into the bloodstream).
What is the main function of the respiratory system?
To supply the blood with oxygen and remove carbon dioxide from the body.
What are arteries and veins?
Arteries carry oxygen-rich blood away from the heart to the rest of the body, while veins carry deoxygenated blood back to the heart from the body's tissues
What is the Digestive System?
The Digestive System breaks down the food you eat into tiny nutrients that your body uses for energy, growth, and repair, and then removes the waste.
What are the three main functions of the nervous system?
Sensory input (gathering information), integration (processing that information), and motor output (sending commands to muscles and glands to create a response).
What are hormones?
Your body's chemical messengers travel through the bloodstream to tell different organs and tissues what to do.
What are the main organs of the respiratory system?
The lungs are the primary organs, but the system also includes the nasal cavity, pharynx, larynx, trachea, bronchi, and alveoli.
What does the circulatory system do?
The circulatory system is the body's transportation system. It is made up of your heart, blood, and all the blood vessels that act like roadways to move things around.
What is the role of the GI tract?
The GI tract is a long tube that takes food from your mouth, breaks it down into nutrients your body can use, and then eliminates the leftover waste.
What are the two main divisions of the nervous system?
The Central Nervous System (CNS), which includes the brain and spinal cord, and the Peripheral Nervous System (PNS).
How does the Endocrine System work?
The endocrine system utilizes hormones to regulate and coordinate the body's various functions.
What is the role of the epiglottis?
It's a flap of cartilage that prevents food and water from entering the airway and lungs.
Explain pulmonary circulation.
Pulmonary circulation is the short, continuous loop that carries blood from your heart to your lungs to pick up oxygen, and then back to your heart. It's like a car taking a quick detour to the gas station to refuel before hitting the highway.
How does food move through the Digestive System?
Food moves through your digestive system via muscular contractions and fluid dynamics.
How do neurons communicate?
Neurons communicate through a combination of electrical signals. (Within the neuron and chemical signals between neurons at specialized junctions called synapses).
What are the signs of an endocrine problem?
(You can list any). Unexplained weight changes, extreme fatigue, changes in heart rate or blood pressure, mood swings, excessive thirst or urination, and changes in skin, hair, or vision.
Why is nasal breathing preferred?
It filters, warms, and moistens incoming air more effectively than mouth breathing.
What are the different parts of the blood?
Plasma (the liquid carrying everything else), red blood cells (which carry oxygen), white blood cells (which fight infection), and platelets (which help stop bleeding by forming clots).
What do the liver, pancreas, and gallbladder do?
The liver acts as a processing plant, the pancreas as a digestive aid and blood sugar regulator, and the gallbladder as a storage tank for the liver's special juice. All three work together to help digest food and keep your body healthy.
What is the function of the cerebrum?
The cerebrum is the "thinking part" of your brain. (It is the largest part of your brain and handles all of your conscious thoughts and voluntary actions, as well as intelligence, memory, and personality).
How does the endocrine system compare to the nervous system?
The nervous system is like sending a text message, while the endocrine system is like sending a letter through the mail.
What triggers the urge to breathe?
An increase in carbon dioxide levels in the blood primarily triggers the urge to breathe in a healthy individual.
What are the main parts of the circulatory system?
The heart and blood vessels make up the circulatory system.
Where does most absorption happen?
Most absorption of nutrients happens in the small intestine. This is where food, now broken down into smaller particles, is absorbed into the bloodstream so the body can use it for energy, growth, and repair.
What is the autonomic nervous system (ANS)?
(Involuntary actions). The autonomic nervous system is your body's "autopilot," handling all the functions you don't have to consciously think about. It keeps things like your heart rate, breathing, and digestion working smoothly in the background to keep your body balanced.
