What is the Wear and Tear theory of aging?
Idea that just like a machine, the human body and human cells break down and cease to function given enough time.

What is the difference between soft vs. hard tissues?
Hard tissues are mineralized and can barely flex.
100
What is the most common type of tissue in the human body?
Connective tissue.
200
What is the Genetic Control theory of aging?
Idea that our DNA codes for exactly how long we will live to be.
200
What is Cartilage?
The connective tissue that provides flexible support and reduces friction between bones.
200
Why do Cartilage, Ligaments, and Tendons heal slowly?
Cartilage gets no blood flow
Ligaments and Tendons get minimal flood flow.
300
What is the Free Radical theory of aging?
Things such as pollution, radiation, unhealthy diets, etc. damage our DNA over time.
300
What are Tendons?
Connective tissues that connect muscle to bone and transmit the force of contraction to move the bone.
300
What are the four main types of tissues in the human body?
Epithelial, Muscle, Nervous, and Connective
400
What is the Telomere theory of aging?
The telomeres that protect our chromosomes shorten over time with every cell division.
400
What are Ligaments?
Connective tissues that connect bone to bone and stabilize joints.
400
What is a good example of Diffusion occuring in the human body?
Oxygen and Carbon Dioxide Exchange in the lungs, Nutrient and Waste Movement in cells, Across Cell Membranes
500
What is the Mitochondrial Theory of aging?
Idea that the powerplants of cells, mitochondria, break down over time and become less efficient and produce free radicals.
500
Which is which?
Are Tendons Flexible or stretchy?
Are Ligaments Flexible or Stretchy?
