Cells and Mitosis
What is Cell Theory?
1. All living organisms are composed of cells. 2. The cell is the basic unit of life. 3. Cells arise from pre-existing cells.
What type of blood does the right side of the heart pump?
deoxygenated
What are Alveoli?
an air-filled grape like sac in the lungs that permit diffusion into capillaries
What is a stem cell?
A cell that doesn't have a specific job yet, and can be programmed to perform a specific function
What gases are diffused in the respiratory system?

Mitochondria!
What is the Right Atrium?
The chamber of the heart receives deoxygenated blood from the rest of the body
What is the smallest blood vessel?
What is a capillary?
What happens in cytokinesis?
Cell membrane pinches inward, Two daughter cells are formed
The molecule that allows oxygen molecules to attach to red blood cells
What is Hemoglobin?

Golgi Body
What is chemical digestion?
The type of digestion that makes use of hydrochloric acid enzymes such as amylase
What is Metaphase?
When the chromosomes line up in the center of the cell and the mitotic spindle is formed
What is the function of the pancreas?
secretes enzymes and hormones
This organelle provides structural support to the cell.
The Cytoskeleton
What are the steps of inhalation?
Diaphragm flattens, lungs increase in volume, pressure decreases, air draws in
What is the function of the integumentary system?
What happens during prophase?
nuclear membrane dissolves, chromatin condenses to chromosomes
A tough yet flexible band of fibrous, connective, tissue that attaches skeletal muscles to the bones and enables you to move
What is a tendon?
This organelle transports proteins throughout the cell
What is the rough endoplasmic reticulum?
The type of blood vessel that ALWAYS carries blood away from the heart.
What are Arteries?
