What is the main function of the circulatory system?
to transport oxygen, nutrients, and hormones to the cells of the body while removing waste products
What is the main organ in the circulatory system that pumps blood throughout the body?
Heart
What role does the digestive system play in providing energy for the body?
breaks down the food we eat into smaller molecules(like glucose). These molecules provide energy to the body’s cells for various functions
How does the circulatory system deliver oxygen to the cells after it is absorbed by the lungs?
oxygen enters your lungs and moves into your blood. Red blood cells in your blood pick up the oxygen and carry it through your body
Which lung disease makes it difficult to breathe and is often caused by long-term exposure to cigarette smoke?
Chronic Obstructive Pulmonary Disease (COPD)
How does the respiratory system contribute to gas exchange in the body?
allows oxygen to enter the bloodstream through the lungs and removes carbon dioxide from the blood by exhaling it
Which organ in the digestive system is responsible for producing bile to aid in the digestion of fats?
Liver
How does the circulatory system support the body's overall function?
transports oxygen and nutrients to cells throughout the body and removes waste products like carbon dioxide. It also helps regulate body temperature and transports hormones
How do the immune system and lymphatic system work together to protect the body from infections?
immune system attacks harmful things like bacteria and viruses. The lymph nodes, which are small glands, act like filters that trap germs and help the immune cells destroy them.
What is the name of the degenerative joint disease that leads to pain and reduced mobility due to the breakdown of cartilage?
Osteoarthritis
What is the role of the digestive system in nutrient absorption?
breaks down food into smaller molecules so that nutrients can be absorbed into the bloodstream through the walls of the small intestine and then transported to cells for energy and growth.
What organ in the respiratory system is responsible for exchanging oxygen and carbon dioxide during breathing?
Lungs
The immune system ___ the body from diseases.
Protects
How do hormones regulate the menstrual cycle in females?

How does the nervous system coordinate body functions and respond to stimuli?
controls and coordinates body functions through electrical signals transmitted by neurons. It receives sensory input, processes information in the brain and spinal cord, and sends motor commands to muscles and glands to respond to stimuli.
In the nervous system, which part of the brain is responsible for controlling balance and coordination?
Cerebellum
The muscular system allows us to live by allowing all types of ____ in the body which lets us live because of the body system it supports.
movement
How do the nervous and endocrine systems work together to regulate stress responses in the body?
brain sends signals to the adrenal glands, telling them to release adrenaline (which makes your heart beat faster) and cortisol (a stress hormone)
Which autoimmune disease attacks the protective covering of nerve fibers, causing symptoms like muscle weakness, coordination issues, and vision problems?
Multiple Sclerosis (MS)
How do the kidneys maintain homeostasis in the body through filtration and excretion?
They filter waste products and excess substances from the blood, forming urine. This helps maintain fluid balance, regulate blood pressure, and keep electrolyte levels stable
Which gland in the endocrine system regulates metabolism and is located in the neck, producing hormones like thyroxine?
Thyroid gland
What is the role of the nervous system in regulating other body systems?
The brain processes information and sends commands to organs, muscles, and glands, helping to regulate heart rate, digestion, movement, and even emotional responses
