Vocabulary
What term describes the group of organs that work together to perform a specific function in the body?
Organ System
How do the respiratory and circulatory systems work together?
The respiratory system brings in oxygen, which the circulatory system transports to cells, while the circulatory system carries carbon dioxide back to the lungs for exhalation.
What is homeostasis?
The ability of the body to maintain a stable internal environment.
What organ is primarily responsible for filtering blood in the excretory system?
Kidneys
What are the four main types of infectious agents that can infect the human body?
Viruses, Bacteria, Fungi, and Parasites
Name the system responsible for transporting oxygen and nutrients throughout the body.
Circulatory System
Give an example of how the digestive system interacts with another body system.
The digestive system provides nutrients to the circulatory system for distribution throughout the body.
Name one way the body responds to maintain homeostasis when it is too hot.
Sweating
Name the organ that is part of the respiratory system and allows for gas exchange.
Lungs
What type of infectious agent is made up of living cells and can reproduce on its own?
Bacteria
What is the term for tiny infectious agents that can cause disease, often requiring a host to reproduce?
Viruses
What system helps protect the body from infectious agents?
Immune System
How does the immune system contribute to homeostasis?
It protects the body from pathogens that may disrupt internal balance.
Which organ is part of the digestive system and helps in the absorption of nutrients?
Small Intestine
Which type of infectious agent typically requires a host cell to replicate?
Virus
Organ Systems working together to perform a specific function is known as?
Organism
Describe how the nervous system interacts with the muscular system during physical activity.
The nervous system sends signals to muscles to contract, allowing for movement.
How does the immune system contribute to homeostasis?
The body may experience illness or disease as systems become unbalanced.
Identify a function of the heart within the circulatory system.
Pumping blood throughout the body.
What is a common disease caused by a fungus usually found on people?
Athlete's Foot
Define homeostasis in your own words.
The process by which the body maintains a stable internal environment despite external changes.
Explain how the excretory system helps maintain homeostasis.
The excretory system removes waste products and regulates water and electrolyte balance in the body.
Explain the importance of maintaining homeostasis for overall health.
Maintaining homeostasis is crucial for proper functioning of bodily systems, overall health, and survival.
What is the role of the brain in the nervous system?
It processes information and coordinates responses to stimuli.
How do parasites disrupt homeostasis in their hosts?
By taking nutrients from the host or causing damage to tissues, which can lead to illness.
