Body systems&functions
What is the primary function of the circulatory system?
To transport blood, oxygen, and nutrients throughout the body.
How do the digestive and circulatory systems work together?
The digestive system breaks down food into nutrients, and the circulatory system transports those nutrients to the rest of the body.
Define "homeostasis."
The maintenance of a stable internal environment in the body.
What happens if the circulatory system stops working properly?
Cells won’t get oxygen and nutrients, leading to organ failure and death.
Which system is responsible for removing waste from the body?
The excretory system
Explain how the muscular system and the skeletal system interact.
The muscular system moves the bones of the skeletal system to create movement.
Function of Cell membrane
Lets substances in or out
Identify the major organ responsible for filtering blood in the excretory system.
The kidneys.
What does the respiratory system do when the body requires more oxygen, such as during exercise?
The respiratory rate increases to bring in more oxygen.
How does the respiratory system interact with the circulatory system?
The respiratory system provides oxygen to the blood, and the circulatory system transports it to cells.
Which two systems are involved in transporting oxygen to cells and removing carbon dioxide from the body?
The respiratory and circulatory systems.
What is the term for a group of organs working together to perform a specific function?
A system.
Label the major organs of the respiratory system.
The lungs, trachea, bronchi, and diaphram.
How does the immune system respond to a virus entering the body?
The immune system identifies and attacks the virus, often using white blood cells.
What is the main role of the digestive system?
To break down food and absorb nutrients.
What system regulates the release of hormones and how does it interact with other systems?
The endocrine system; it releases hormones that regulate activities in other systems, like growth and metabolism.
Nucleus
Contains DNA and controls the system
What might happen if the nervous system stops sending signals to the muscles?
Muscles wouldn’t move, leading to paralysis.
Which system protects the body from harmful pathogens/viruses?
The Immune system
Describe the interaction between the nervous system and the muscular system.
The nervous system sends signals to muscles, causing them to contract and produce movement.
What is the difference between voluntary and involuntary actions? Provide an example of each.
Voluntary actions are controlled by conscious thought (e.g., walking), while involuntary actions happen automatically without conscious control (e.g., heartbeat).
What is the function of the small intestine in the digestive system?
To absorb nutrients from food into the bloodstream.
If the endocrine system stops releasing insulin, what could happen to the body?
Blood sugar levels would become too high, leading to conditions like diabetes.
