Digestive System
What organ stores bile before it is released into the small intestine?
What is the gallbladder?
What organ pumps blood throughout the body?
What is the heart?
What organ filters waste from the blood to produce urine?
What are the kidneys?
What organ is primarily responsible for gas exchange?
What are the lungs?
What hormone helps regulate blood sugar levels?
What is insulin?
What are the main functions of the small intestine?
What is digestion and nutrient absorption?
Which blood vessels carry blood away from the heart?
What are arteries?
What tube carries urine from the kidney to the bladder?
What is the ureter?
What structure prevents food from entering the trachea?
What is the epiglottis?
Why are hormones important for maintaining homeostasis in the body?
What is because hormones regulate body processes like growth, metabolism, and blood sugar balance?
If digestive enzymes were no longer produced, which organ would most likely be malfunctioning?
What is the pancreas?
A person loses a large amount of blood. Which blood component drop would most directly reduce oxygen delivery?
What are red blood cells?
A person’s kidneys stop working properly. What medical treatment would they need to filter waste from their blood?
What is dialysis?
If the alveoli in the lungs were damaged, how would oxygen levels in the blood be affected?
What is oxygen levels would decrease because gas exchange would not occur effectively?
If the body releases adrenaline during a dangerous situation, what immediate effect would most likely occur?
What is increased heart rate and energy?
A scientist notices nutrients are not entering the bloodstream after digestion. Which digestive organ is most responsible for this problem and why?
What is the small intestine because it absorbs nutrients into the bloodstream?
Why would damage to the left ventricle be more dangerous than damage to the right ventricle?
What is because the left ventricle pumps oxygenated blood to the entire body?
If the kidneys fail to remove excess water from the blood, what would happen to blood volume and pressure?
What is both would increase, leading to higher blood pressure and swelling?
A person has damaged intercostal muscles. How would this affect breathing?
What is chest expansion would decrease, making breathing harder?
A tumor causes the pancreas to overproduce insulin. What would likely happen to blood glucose levels and body function?
What is blood glucose would drop too low, causing weakness, confusion, and possible loss of consciousness?
A disease damages the villi lining the small intestine. Explain how this would affect nutrient absorption.
What is absorption would greatly decrease because reduced villi surface area limits nutrients entering the bloodstream?
A person has damaged heart valves that cause blood to flow backward in the heart. How would this affect circulation efficiency and oxygen delivery to the body?
What is because backflow reduces the amount of blood pumped forward each heartbeat, lowering overall circulation efficiency and decreasing oxygen delivery to tissues?
A person has severely low blood pressure due to dehydration. Explain how the RAAS responds and how it helps restore blood pressure.
What is the kidneys release renin, which activates a hormone pathway that leads to vasoconstriction and increased sodium and water reabsorption, raising blood pressure and restoring blood volume?
During free diving, a person holds their breath for a long time while descending underwater. How does this affect oxygen and carbon dioxide levels in the body, and why can this become dangerous?
What is oxygen levels decrease while carbon dioxide builds up, which can lead to loss of consciousness because the brain is no longer receiving enough oxygen?
After a person eats a fatty meal, the hormone CCK is released. Explain how CCK helps digestion.
What is CCK stimulates the release of digestive enzymes from the pancreas and bile release to help break down fats?
