What are muscles?
Skeletal muscles are either voluntary or involuntary
What is voluntary?
This is what causes varicose veins
What are weakened valves?
Name the two different types of respiration
What are aerobic (with air) and anaerobic (without air)?
This is the layer of skin affected by first degree burns
What is the epidermis?
There are two main systems that help move the human body: the skeletal system and this
What is the muscular system?
Smooth muscles are either striated or aren't striated
What is aren't striated?
These types of muscles help move blood around the body
What are cardiac muscles tissue?
This is the process where the energy for the body comes from
What is Cellular Respiration?
The 3 main roles of skin
What are protection (physical barrier against pathogens), sensation (danger through pain), and temperature regulation (shifts the diameter of blood vessels in the blood to lose or retain heat)?
This kind of synovial joint makes up the shoulder
What is ball-and-socket joint?
In order for muscles to contract, they have to receive a message from this system
What is the CNS (Central Nervous System)?
The left side of the heart is responsible for the control of this kind of circulation and the right side is responsible for the control of the other, respectively
What is 1. systemic circulation and 2. pulmonary circulation?
When the muscles can't generate enough force to perform certain tasks

What are muscle fibers?
The structures of arteries, veins, and capillaries relate to their function in the body in these ways (hint: think walls)
What are:
Arteries - Thick walls to handle high pressure as it leaves the heart
Veins - Elastic/Collapsible walls with valves to prevent backflow of blood as it moves toward the heart
Capillaries - Thin walled and microscopic in size to allow exchange materials
The body systems required to power an athlete through a race
What are the digestive, respiratory, and cardiovascular systems?
(Releases stored glucose from the liver - Brings a steady supply of oxygen needed to combust glucose - Carried O^2 glucose to the cells to be converted into energy within the mitochondria)
Where the sebaceous glands begin (hint: it's one of the layers of skin)
What is the hypodermis?
