Test 3: Anatomy & Physiology Packet 1 Flashcards
What is anatomy/ Define it
The study of an organisms body structures and their locations
What is physiology/ define it
The study of the functions of each body part
Label each of the following examples as anatomy or physiology
What is the purpose of the tongue?
Where are phalanges located?
Where is the ear drum located?
How do eyes communicate what you see to the brain?

Briefly describe Anaphase
Chromatids are pulled apart and the one cell is starting to form 2 cells
The human body has ______ levels of structural organization
6
What are the 6 levels of structural organization
- Chemical
- Cellular
- Tissue
- Organ
- Organ system
- Organism
- Atomic
- Molecular
- Cellular
-Tissue - Organ
- Organ system
- Organism
T/F
DNA is an example of a molecule
True
How does a molecule form
When two or more atoms form chemical bonds with eachother
What are cells
The smallest structural unit of living things, which carry on all of the functions of life
The three reasons why cells reproduce are….
- Growth
- Repair
- Maintenance
What are the two methods of cell division called in reproducing cells?
Mitosis and Meiosis
What are the functions of life (4)
- Taking in food and oxygen
- Producing heat and energy
- Eliminating wastes
- Reproducing to create new cells
Briefly Describe Prophase
Chromatids coil up and the nucleus dissolves
Briefly describe Interphase
The cell is resting and gaining/ storing energy
When does Mitosis occur
When one cell reproduces by dividing into two identical cells
Briefly describe Metaphase
Chromatids line up in the middleabd the centrioles connect in the middle
What are the stages of Mitosis
I Picked My Apples Today
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
Briefly describe Cytokonesis
2 cells with 46 chromosomes Each are formed and the two cells are exact copies
Briefly describe Telophase
The chromatids begin to uncoil. There is still one cell but two nuclei within it
T/F
The process of Meiosis begins with one cell that has 46 chromosomes and ends with 4 cells with 23 chromosomes
True
What are sex cells also called
Gametes
What is Anabolism
(Something + energy = bigger)
Involves building up of complex substances from simpler ones
What is Metabolism (In cells)
The sum of all chemical reactions within a cell. It refers to when cells take in and use nutrients to produce energy and growth
What is Catabolism
(Something big + energy = small)
Involves breaking DOWN complex substances into simpler ones
