Body Systems
The three body systems that we've been studying in our metabolism unit
Digestive, respiratory, and circulatory
Which body system includes the mouth/nose, lungs, windpipe, bronchi, and alveoli?
Respiratory system
Which three molecules do our cells need to function?
Oxygen, glucose, and amino acids
In a functioning human body, body systems work together to deliver what to the cells in the body?
molecules (glucose, oxygen, amino acids)
What is an example of a protein rich food?
Eggs, meat, beans, nuts
This system takes in food and breaks it down
Which body system includes the heart, blood, arteries, and veins?
Circulatory system
Where does our body get oxygen?
the air around us
The respiratory system brings in _________ molecules from the air. These molecules are already small enough to fit into cells.
oxygen
What is an example of starchy foods?
bread, fruits, vegetables, pasta
This system transports molecules to and from every cell in the body
The circulatory system
Which body system includes the mouth, esophagus, stomach, small intestine, and large intestine?
Digestive system
Where does our body get glucose and amino acids?
The food we eat (starch and protein)
The digestive system brings in food and breaks it down into smaller molecules, such as __________ and ___________, that can fit into cells.
glucose and amino acids
What acidic liquid in our stomachs help break down food?
Digestive enzymes
This system takes in oxygen and release carbon dioxide
Respiratory system
Once oxygen enters the lungs, they go to the alveoli, which is where what happens?
Which molecule is the building block of protein?
Amino acids
The circulatory system transports glucose, oxygen, and amino acid molecules to _________________.
every cell in the body
Arteries carry blood _______________ the heart and veins carry blood _________________ the heart.
away from, to
Name another body system (one we haven't learned about)
Skeletal, muscular, nervous, reproductive, urinary
What do the villi in our small intestine do?
Absorb/soak up the nutrients from our food (glucose and amino acids)
Which molecule, known as simple sugar, is broken down from starchy foods?
Glucose
Systems can work together to form a ________________________.
larger, more complex system
The body's use of molecules for energy and growth
