Body Systems in Action
Which body system is responsible for taking in food and breaking large food molecules down into smaller ones?
What is the digestive system?
What two types of molecules must enter a cell for cellular respiration to take place and release energy?
What are glucose and oxygen?
If a person's respiratory system is impaired by asthma, which specific molecule will be delivered in smaller amounts to their cells?
What is oxygen?
What is the basic microscopic unit of structure and function in all living things?
What is a cell?
What are the two main ways human bodies physically take in required molecules from their environment?
What is by eating (ingestion) and breathing (inhalation)?
Which body system brings oxygen into the body and releases waste carbon dioxide back into the air?
What is the respiratory system?
Why are large molecules like starch and protein unable to be used by cells directly after eating?
What is because they are too large to pass through the cell membrane and must be broken down first?
Why does a person with a pancreas injury or diabetes struggle to maintain high energy levels during exercise?
What is because fewer glucose molecules make it into cells to release energy?
What is formed when a group of similar cells work together to perform a specific function?
What is a tissue?
True or False: Breathing air into your lungs and cellular respiration inside your cells are the exact same process.
What is False? (Breathing takes in air; cellular respiration is a chemical reaction in cells that releases energy).
Which body system acts as a highway to transport glucose, oxygen, and amino acids to cells all over the body?
What is the circulatory system?
What tiny organelle inside cells is known as the "powerhouse" where cellular respiration occurs?
What is the mitochondrion (mitochondria)?
A medical condition that causes low red blood cells and leads to reduced oxygen delivery throughout the body is known as what?
What is anemia?
Put these four levels of biological organization in order from smallest to largest: Organ, Cell, System, Tissue.
What is Cell, Tissue, Organ, System?
Why is fiber unable to provide our body's cells with energy, even though it is present in the food we eat?
What is because human digestive systems cannot break fiber down into small usable molecules like glucose?
How do the digestive system and circulatory system work together after you eat a meal?
What is the digestive system breaks food into small molecules, and the circulatory system delivers them to cells?
Which small molecules serve as the building blocks that cells use to build proteins for growth and repair?
What are amino acids?
If a patient is chewing and swallowing food properly, but their digestive system fails to break it down, why will their cells lack energy?
What is because food molecules remain too large to enter the cells?
Is the stomach considered a tissue, an organ, or an organ system?
What is an organ?
In a Claim-Evidence-Reasoning (CER) model, what part connects your scientific evidence back to your main claim?
What is the reasoning?
Besides bringing oxygen into the body, what crucial waste removal job does the respiratory system perform?
What is removing carbon dioxide from the body/bloodstream?
What happens to the total number of atoms when glucose and oxygen undergo a chemical reaction inside a cell?
What is the total number of atoms stays the same (they are rearranged to form new products)?
How can a problem in one body system (like the digestive system) cause problems for cellular function across the whole body?
What is because cells in every system rely on the molecules that body systems collect and transport?
What is the term for a set of interacting parts or organs that work together as a complex whole?
What is a system?
If a person gets plenty of sleep and breathes normally, why might a lack of eating still prevent them from exercising effectively?
What is because cellular respiration requires both oxygen AND glucose from food to release energy?
