CELLS & MITOSIS
This process creates identical copies of a cell for growth and repair.
Mitosis
This is the smallest unit considered alive.
Cell
This muscle tissue is voluntary and attaches to bones.
Skeletal Muscle Tissue
Name one organ in the digestive system that chemically digests food.
mouth - amylase
stomach - hydrochloric acid
small intestines - pancreatic enzymes
Bones meet at these locations to allow movement.
Joints
These bowl-shaped cells carry oxygen and squeeze through tiny blood vessels.
Red Blood cell
Groups of similar cells working together form this level.
Tissue
This tissue supports, connects, and protects (like bone, fat, and blood).
This system moves nutrients absorbed by the small intestine to all of our cells.
Circulatory system
These strong bands hold bones together at the joints.
Ligaments
These cells are long, stretchy, and multinucleated.
Muscle Cell
A complete living thing formed by all body systems working together.
Organism
This tissue covers the body and lines almost every organ (skin, stomach lining).
Epithelial Tissue
When you feel hungry, which two systems are mainly interacting?
Nervous System & Digestive System
Describe the length of a muscle fiber during a muscle contraction.
Shorter
This cell type is long with many branches to send signals throughout the body.
Nerve cell (neuron)
List the 4 tissue that make up the stomach organ
connective
nervous
muscular
epithelial
This muscle tissue type lacks aligned contractile filaments, causing its contractions to be slower and less forceful, but allowing it to operate continuously in multiple directions.
Smooth muscle tissue
What finger-like projections increase surface area in the small intestine to allow nutrients to enter the circulatory system?
Villi
This type of skeleton allows organisms to squeeze into tiny spaces because muscles push fluid inside the body.
Hydrostatic Skeleton
Name the correct order of mitosis:
- Metaphase
- Telophase
- Prophase
- Anaphase
PMAT
What is the correct order of organization (all 8 levels) from least complex to most complex?
atom
molecule
organelle
cell
tissue
organ
organ system
organism
What helps cardiac muscle keep a steady and strong heartbeat preventing the cells from tiring out.
branched and interconnected cells
What are the 5 functions of the skeletal system?
1. structure and support
2. protection
3. movement
4. makes new blood cells
5. stores minerals: calcium and phosphorus
Name the smooth muscle contraction that moves food throughout the digestive system.
Peristalsis
