🏠 Homeostasis
Keeping the body's internal conditions stable.
What does homeostasis mean?
What organ pumps blood through the body?
The heart.
What gas does your body need to survive?
Oxygen.
What is the main job of the digestive system?
To break down food and absorb nutrients.
What does the endocrine system produce?
Hormones.
What is one example of something your body keeps stable?
Body temperature.
What does blood transport throughout the body? (Name at least 1 thing)
Oxygen, nutrients, hormones, and wastes.
What gas does your body get rid of when you breathe out?
Carbon dioxide.
Where does most nutrient absorption occur?
The small intestine
How do hormones travel throughout the body?
Through the bloodstream/ Circulatory
You are hot and begin to sweat. How does sweating help maintain homeostasis?
Sweating helps cool the body and bring its temperature back toward normal.
Which blood vessels carry blood Away from the heart?
Arteries.
Where does oxygen move into the blood?
At the alveoli ( grape clusters/ balloons) in the lungs.
If food is broken down into smaller molecules that the body can absorb and use. What process is happening?
What is Digestion
Which hormone helps lower blood glucose levels?
Insulin
Your blood sugar becomes too high after eating. Your body releases a hormone that helps lower it. What process is occurring?
Homeostasis.
This condition occurs when blood flow to the heart muscle is suddenly blocked, causing tissue damage and/ or fatality.
What is a heart attack
How does oxygen get from your lungs to your body cells? (What body system helps)
Oxygen moves from the alveoli into the blood, and the circulatory system transports it to body cells.
After nutrients are absorbed in the small intestine, how do they reach cells throughout the body?
They enter the bloodstream and are transported by the circulatory system.
Hormones travel through the bloodstream and generally act more
________ (slowly, faster), than the Nervous system but their effects can last longer.
Slower
You are exercising on a hot day. You begin sweating, your heart beats faster, and you breathe faster. Which body systems are working together to help maintain homeostasis?
Nervous, circulatory, respiratory, and integumentary systems (Skin)
You get a cut on your leg. Your body needs to deliver oxygen, nutrients, and other materials to the damaged area to help it heal. Which systems work together?
Integumentary (skin), Nervous System- sends the signal, The respiratory system brings oxygen into the body, and the circulatory system transports the oxygen to the damaged cells.
You hold your breath underwater for too long. Your cells begin receiving less oxygen. Which two systems normally work together to get oxygen to your cells?
The respiratory system brings oxygen into the lungs, and the circulatory system carries oxygen in the blood to cells.
You eat a sandwich before playing a soccer game. Your digestive system breaks the food into nutrients, and those nutrients are delivered to your muscle cells. Which systems are working together?
The digestive system breaks down and absorbs nutrients; the circulatory system transports those nutrients to cells.
Nervous System always at work!
You eat a meal, and your blood glucose level rises. Your body releases insulin, which helps cells take in glucose from the blood. Which systems are working together?
The endocrine system releases insulin, and the circulatory system carries the hormone and glucose through the blood. Digestive System helps you break it down!
