1. There are six levels of organization in the body.
What are they?
1) Chemical
2) Cellular
3) Tissue
4) Organ structure
5) Organ system
6) Organism
2. The necessary life function that protects our internal environment
from our external environment is provided by what system? The
integumentary system
3. The function of movement is provided by what system? The
muscular system
4. The function of responsiveness is provided by what system? The
nervous system
5. The function of digestion is provided by what system? The digestive
system
6. What is anabolism? when more complex structure are broken down
into simpler ones.
7. Excretion involves what systems?
The respiratory system
The digestive system
The urinary system
8. The reproductive system is controled by what other system? The
endocrine system
9. Which tissue covers the body surface and lines the cavities of the
body? The epithelial tissue.
10. Name the three steps in cellular respiration.
Glycolysis
Citric acid cycle
electron transport chain
11. What is the purpose of ATP? ATPprovides cells whith the energy
necessary to carry out cellular activitiesand function
12. Epithelial cells perform what types of function? Secreation and
absorption
, 13. What are the four basic types of tissues?
Epithelial
Muscle
Connetive
Nervous
14. What is homeostasis? The process of maintaining a stable internal
environment despite changes in external conditions.
15. Which organ system is primarily responsible for regulating
homeostasis? The nervous system and the endocrine system work
together to maintain homeostasis.
16. What is the role of the skeletal system? The skeletal system
provides structure, support, and protection for vital organs, as well
as enabling movement in conjunction with the muscular system.
17. What are the components of blood? Red blood cells, white blood
cells, platelets, and plasma.
18. What is the main function of the respiratory system? The respiratory
system is responsible for the exchange of gases; it brings oxygen
into the body and expels carbon dioxide.
19. What are the major organs of the digestive system? The mouth,
esophagus, stomach, intestines, liver, gallbladder, and pancreas.
20. What is the purpose of the urinary system? The urinary system
removes waste products from the body and regulates electrolyte
balance and blood pressure.
21. What are the three main types of muscle tissue? Skeletal muscle,
smooth muscle, and cardiac muscle.
22. How do neurons communicate with each other? Neurons
communicate through chemical signals called neurotransmitters
across synapses. What is the basic unit of nervous tissue? The
neuron is the basic unit of nervous tissue, responsible for
transmitting signals throughout the body.
23. What are the functions of connective tissue? Connective tissue
supports, binds together, and protects tissues and organs of the
body. It also stores energy and helps in immune responses.
24. Name the different types of epithelial tissue. Simple squamous,
simple cuboidal, simple columnar, stratified squamous,
pseudostratified columnar, and transitional epithelium.
25. What is the role of adipose tissue? Adipose tissue stores energy in
the form of fat, provides insulation, and serves as a cushion for
organs.
