Science 6: Reviewer for First Quarterly Exam

A patient is experiencing difficulty digesting fats and also has yellowing of the skin. Which organ system is most likely affected, and why?

• Respiratory system, because the lungs is malfunctioninng and it affects oxygen absorption

• Nervous system, because the brain is malfunctioninng and it regulates bodily functions

• Digestive system, because the liver is malfunctioning and failing to process fats properly

• Circulatory system, because blood flow is restricted due to the heart mulfunctioning

A person complains of shortness of breath and fatigue after mild exertion. Which two systems should be evaluated first, and why?

• Respiratory and circulatory systems, because they supply oxygen and transport it to the cells

• Nervous and digestive systems, because they control energy use and nutrient absorption

• Musculoskeletal and circulatory systems, because they work together to provide movement and oxygen delivery

• Digestive and excretory systems, because they manage waste and nutrients

A doctor observes that a patient has trouble coordinating their movements and often feels dizzy. Which part of the nervous system might be compromised, and how could it affect other systems?

• Brain, causing poor balance and affecting muscular control

• Spinal cord, leading to numbness in the limbs

• Autonomic nervous system, disrupting heart rate and digestion

• Peripheral nerves, causing muscle weakness and respiratory issues

A child is born with a defect in their trachea that makes breathing difficult. How would this impact their growth and development over time, considering the role of other organ systems?

• The respiratory system would compensate by increasing lung function, supporting normal growth

• The circulatory and digestive systems would struggle to supply oxygen and nutrients, leading to delayed growth

• The nervous system would compensate by improving coordination, offsetting the respiratory issue

• The skeletal system would grow faster to provide more space for the lungs

During intense physical activity, a person’s heart rate increases, and they start breathing heavily. How do the circulatory and respiratory systems collaborate to maintain the body's energy levels?

• The circulatory system supplies extra nutrients to muscles, reducing the need for oxygen

• The circulatory system slows down to allow the respiratory system to catch up

• Both systems focus on energy storage rather than immediate energy use

• The respiratory system increases oxygen intake, and the circulatory system delivers it faster to muscles

Consider a scenario where a person's heart is unable to pump effectively. How would this impact the delivery of nutrients from the digestive system?

• The digestive system compensates by increasing nutrient absorption

• Nutrients build up in the bloodstream because they cannot be transported to cells

• The body shifts its focus to digesting food faster to supply nutrients

• Nutrient delivery slows down, leading to fatigue and weakened bodily functions

A person consumes a meal high in fats and then engages in vigorous exercise. How do the digestive and circulatory systems respond, and how might this impact performance?

• The digestive system breaks down the fats quickly to supply energy for exercise, improving performance

• The circulatory system prioritizes oxygen delivery over digestion, leading to potential digestive discomfort during exercise

• The digestive system slows down, allowing the circulatory system to focus on delivering nutrients

• Both systems work together to enhance performance by rapidly processing and delivering nutrients

Imagine a person who has difficulty walking because of muscle weakness. Which organ systems might be involved, and how do they interact?

• Immune and skeletal systems, because infections weaken bones and muscles

• Nervous and circulatory systems, because poor blood flow affects nerve signals to muscles

• Musculoskeletal and nervous systems, because nerve signals control muscle contractions for movement

• Digestive and respiratory systems, because oxygen and nutrients affect muscle strength

A person has weak bones and frequent fractures. Which other system is most likely affected, and how does it contribute to the problem?

• • Digestive system, because it may not be absorbing enough calcium

• Circulatory system, because poor blood flow weakens bones

• Nervous system, because poor coordination leads to more falls

• Respiratory system, because reduced oxygen affects bone health

After a heavy meal, a person feels sleepy and sluggish. How does the body's system prioritize energy use, and what is the impact on the nervous system?

• • The digestive system slows down to conserve energy, leading to less energy for the brain

• The nervous system redirects energy from the digestive system, causing sluggish digestion

• The digestive system requires more energy, leading to reduced brain function temporarily

• The circulatory system increases blood flow to the brain, reducing digestive efficiency
