Reference: Body Systems

Notes
made by Marisa

Circulatory System
The circulatory system carries oxygen (hemoglobin in red blood cells carries O2) and nutrients to the cells all over the body and carries carbon dioxide and waste away from the cells. 
Respiratory System
The respiratory system brings oxygen (O2) into the body and sends carbon dioxide (CO2) out of the body.
Digestive System
The digestive system breaks down food and adsorbs nutrients for the body. It is aided by bacteria that live in the intestines and help break down complex nutrients. 
Nervous System
The nervous system collects and stores information from inside and outside the body. It controls the body's actions and its responses to any changes. All five senses are part  of the nervous system.
Skeletal System
The skeletal system gives your body structure and protects your internal organs. It stores minerals and produces blood cells in the bone marrow. 
Muscular System
The muscular system is responsible for all of the body's movements, both voluntary (jumping, chewing, walking, etc.) and involuntary (breathing, stomach churning, etc.). 
Endocrine System
The endocrine system produces chemical messengers called hormones that help maintain homeostasis and control growth and development.
Integumentary System
The integumentary system is your skin. It serves as a protective barrier around your body preventing water loss and helping to control body temperature. 
Immune System
The immune system is made of antibodies and white blood cells that protect your body from infection. HIV attacks a special type of white blood cell known as the Helper T cell.
Reproductive System
The reproductive system produces the gamete cells required for sexual reproduction. The male cells are known as sperm and the female gamete cells are known as eggs.
Excretory System
The excretory system removes waste from the body and helps the body maintains homeostasis by preventing the buildup of excess fluid and solid material within the body. 


Even though I took HTML and Dreamweaver, this was so tedious!
Hope this helps!

Study Time 1: Garden Variety



This is to help me in the future. So enjoy, if you find this useful! ps I got a 97% on this. Number 20, I'm not sure on the answer. Also I may not do the questions with diagrams; they will have the ~~~~~ symbols.

Biology Review: Adapations in Plants


1. Which is a characteristic of members of the plant kingdom that distinguishes them from members of the animal kingdom?
Use of chlorophyll for solar-energy transformation

2. Which two kingdoms have members that are photosynthetic?
Plantae and Protista

3. Which process occurs in the chloroplasts of plant cells?
Photosynthesis

4. Which process best shows the conversion of solor energy to chemical energy?
Green plants making their own food

5.  ~~~~~

6. A primary function of a plant root is to --
absorb water and minerals

7. Plant leaves have a waxy covering called a curticle. When some plants are stressed by lack of water, their curticle incresases in thickness. What does this action demonstrate?
structural response to the environment

8. ~~~~~~~

9. Some mesquite trees have deeper roots than amy other plant in the desert. How are deep roots an adaptation for survival in the desert?
Roots can extend great distances to reach water

10. ~~~~~~~~

11. Which of these charateristics might help a plant species survive in an area of limited sunlight?
Large leaves

12. Energy used by producers in a grassland food web is provided by -
sunlight

13. Some species of kelp anchor themselves to the seafloor. These species have small air sacs, called air bladders, at the base of each leaf. The air bladders raise the top of the kelp to the water's surface. What advantage do air bladders give the kelp?
They allow kelp leaves to receive greater amounts of sunlight

14. ~~~~~~~~~~

15. Which of the following characteristics could help short plants survive in areas with limited sunlight?
Broad leaf surface

16. ~~~~~~~~~

17. ~~~~~~~~~~

18. ~~~~~~~~~

19. Which of the following is an adaptation most likely observed in plants growing along ocean's coast?
Tolerance of saltwater

20. I got this one wrong

21.
