Nervous
An Involuntary and almost immediate movement.
What is a reflex?
Breaking, crushing and mashing of food.
What is mechanical digestion?
What do arteries, veins, and capillaries all have in common?
They are all blood vessels.
Oxygen from the atmosphere enters the body and goes into this organ.
What are the lungs?
What is the relationship between cells, tissues, organs, and organ systems?
Cells make tissues, which make organs, which make organ systems.
Why do you have a reflex response?
To protect your body from injury?
Large molecules are broken down into nutrients.
What is chemical digestion?
Which gas do your body cells produce and put into your blood stream?
Carbon Dioxide
Oxygen passes from the lungs and into here. (this part of the body carries the oxygen away from the lungs)
What is the blood stream?
What is immunity?
Being able to resist or recover from a disease.
How do the nervous, muscular, and skeletal systems work to provide movement?
Nervous system tells the muscular system to pull on the skeletal system.
Small projections inside the small intestine that absorb nutrients.
Villi.
Blood vessel responsible for exchanging substances between blood and body cells.
What are capillaries?
The blood stream carries this substance back into the lungs so it can be released into the atmosphere.
What is CARBON DIOXIDE?
What does a vaccine do?
Help your body develop immunity to a disease without getting sick from it.
Define Homeostasis and provide one example of it.
Maintaining a stable internal environment. ex. Sweating to cool your body temperature down.
Where does most chemical digestion occur and where does it pass the nutrients to after being digested?
The small intestine - it passes the nutrients into your blood stream (through the capillaries)
Two substances which your blood transports to every cell in your body.
What are oxygen and nutrients/sugar/food/glucose?
What bridges/connects your respiratory and circulatory systems together? (one part from each)
What are the alveoli (respiratory) and capillaries (circulatory)?
What are three types of pathogens? (not specific diseases)
Viruses, some bacteria, fungi, protists, and worms.
Define each of the cell parts functions: Nucleus, Cell Membrane, Mitochondria, Chloroplasts, Cell Wall
Nucleus- Stores DNA, Control Center Cell Membrane - Outer layer, controls what enters/exits Mitochondria - Provides energy to cell by breaking sugar Chloroplast - uses sunlight to make sugar (stores energy) Cell Wall- rigid outer layer that provides support (NOT protection)
These bridge/connect the digestive and circulatory systems. (one part from each)
What are the villi (digestive) and capillaries (circulatory)?
How do you respiratory and circulatory systems work together to give cells energy?
When you inhale, you take in oxygen (respiratory). This oxygen diffuses into red blood cells (circulatory) and is then carried to body cells. The body cells use the oxygen to release energy from sugar.
Why do organisms need oxygen? (7th grade answer, not Kindergarten answer)
Oxygen is needed to release energy from food/sugar/glucose. Without oxygen, the cells would have no energy and die.
What is the purpose of an antibiotic and identify two types of infections that can be effectively treated with antibiotics? (explain your reasoning)
The purpose of an antibiotic is to kill or slow the growth of a bacteria. Two infections that can be treated with an antibiotic are strept throat and ear infections because they are both caused by a bacterial infection.
