Biological Processes
Which of the following is an example of a vital biological process: Sleeping, Reading, Respiration, or Blinking?
Respiration
What is the main function of the digestive system?
the main function of the digestive system is to break down food and absorb nutrients.
True or False: The lungs are part of the digestive system.
False
Your heart is a muscle that never stops working.
True
What is the purpose of the musculoskeletal system?
The musculoskeletal system helps your body move and stay upright.
This system works closely with the respiratory system to pick up oxygen and deliver it to cells all over the body.
The Circulatory System.
True or false and then explain.
Plants do not need transport systems because they do not move.
What are they moving?
False.
They must be able to move water and nutrients from the ground up the stem to the leaves where glucose is made.
Name three of the five vital biological processes that complex organisms need to stay alive
Movement, Nutrition, Respiration, Growth, and Reproduction
Which of these organs is part of the digestive system: Heart, Lungs, Intestines, or Ribs?
Intestines
This is the main job of our lungs.
To take in oxygen and release carbon dioxide.
What is the main function of the circulatory system?
The main function of this system is to move blood and deliver nutrients and oxygen.
This part of the musculoskeletal system supports the body and protects your organs.
These are the Bones (or the Skeleton).
If the digestive system could not absorb nutrients, what would happen to your muscles?
The muscles would stop working properly due to a lack of energy.
This is the job of the phloem in a plant.
their job is transporting sugars from the leaves to the rest of the plant.
This biological process is defined as "getting bigger and changing over time.
Growth
This long, slippery muscular tube acts like a slide, pushing food from your mouth down to your stomach.
The Esophagus
Name one specific organ or part that belongs to the respiratory system and what it does.
Trachea
Lungs
Diaphragm
Name one specific organ or part that belongs to the circulatory system and explain its job.
Heart
Blood vessles
What is the purpose of muscles and how do they work?
This part of the musculoskeletal system creates movement by pulling on bones.
When you eat a sandwich, the digestive system breaks it down into these tiny pieces of fuel that your body uses to grow and stay healthy.
Nutrients.
This is the job of the xylem in a plant.
their job is moving water and minerals from the roots to the leaves.
This biological process is defined as "taking in food and using it for energy and growth.
Nurtritian
Name one specific organ that belongs to the digestive system and what it's job is.
mouth, stomach, intestines, liver, or pancrea
Also known as the windpipe, this tube carries air from your throat down toward your lungs.
The Trachea.
What is the role of Veins?
These specific blood vessels have the job of bringing blood filled with carbon dioxide and waste back to the heart.
Explain where joints are and what they do.
These are the places where your bones meet, acting like hinges on a door to allow your bones to move in different ways.
What three systems are Nutrients and Oxygen?
The digestive, respiratory, and circulatory systems work together to deliver these two essential things to your muscles.
Which one has a "two-way flow", xylem and phloem,?
Phloem has a two way flow because..
After the stomach, food enters this long organ where tiny finger-like villi collect the nutrients.
The small intestine.
These tiny air sacs inside the lungs are where the magic happens: oxygen goes into your blood and carbon dioxide comes out.
The Alveoli.
What is Blood and what does it do?
As this red liquid travels through your body, it acts as a delivery system for oxygen, nutrients, and waste to and from every single cell.
What is the importance of bones such as the rib cage, skull, and spine, in addition to keeping you upright.
These bones are protecting vital organs, like the heart, lungs, brain, and spinal cord)?
The digestive system breaks down food, the respiratory system breathes in oxygen, and the circulatory system does this.
It carries the nutrients and oxygen through the blood to your muscles for energy.
How is the function of xylem in plants is similar to the circulatory system in animals?
They both move water and nutrients.
