What gives the human body a framework and protection? |
Skeleton |
|
What is mechanical digestion? |
Mechanical digestion is the physical breaking up of food. |
|
What is chemical digestion? |
Chemical digestion is the breaking of chemical bonds in the food so that it is broken into smaller, simpler nutrients that the body can use. |
|
The heart and blood vessels make up which system? |
Circulatory System |
|
The circulatory system works closely with which other system? |
The Respiratory System |
|
To get energy from food nutrients, all cells need a constant supply of __________________ order to complete cellular respiration. |
Oxygen |
|
Animals use the gas __________________ for cellular respiration. |
Oxygen |
|
Plants also use __________________ for cellular respiration. |
Oxygen |
|
The ______________ system in animals takes care of getting oxygen, nutrients, water, etc to the cells of the body, and carrying carbon dioxide away from the cells of the body after cellular respiration. |
Circulatory System |
|
_____________________ in plants transports water and dissolved minerals from the roots to the other parts of the plant. |
Xylem |
|
_______________ in plants transports sugar (nutrients) from the leaves to the roots. |
Phloem |
|
As water evaporates through the leaves of plants, more water is pulled up the thin tubes of ___________________. |
Xylem |
|
Sugar (glucose) moves down the plant as a result of gravity to some degree, but more importantly, by ___________________ pressure |
Water (water pressure is the way that glucose moves down the plant from its leaves to the roots) |
|
The leaves of the plant make sugar (glucose) by photosynthesis and the sugar collects in the _______________ cells. |
Phloem |
|
The sugar draws __________________ into the phloem cells from the xylem. Water pressure in the phloem cells increases, as a result. |
Water |
|
The increased water _______________ forces the sugary water down the plant. |
Pressure |
|
The ability to maintain a constant internal environment is called ____________________. |
Homeostasis |
|
___________________ is the disruption of homeostasis. |
Disease |
|
_________________ disease can be transmitted from person to person. |
Infectious |
|
Infectious diseases are caused by _____________________ like bacteria, viruses, etc. |
Pathogens (micro organisms) |
|
_______________ diseases cannot be passed from one person to another person, although they can still do great harm. |
Noninfectious |
|
Examples of noninfectious _________________ include genetic diseases, mutations, and things like cancer, diabetes, heart disease, etc. |
