Random
100
A place where the elements of skeleton come together.
Joints
100
This is the functional unit of a muscle fiber.
Sarcomeres, made of myosin (thick filaments) and actin (thin filaments)
100
The amount of blood ejected from the left side of the heart in one minute.
Cardiac Output
100
Define muscle fatigue.
The inability of muscle to maintain its strength of contraction of tension; may be related to insufficient oxygen, depletion of glycogen, and/or lactic acid buildup.
100
This feature in veins helps move blood back to the heart.
Valves. Arteries don't have valves.
200
An instrument for measuring angles (as of joint or skull)
Goniometer
200
Interaction between these two filaments are responsible for muscle contraction.
Myosin and Actin
200
The volume of blood pumped by a ventricle in one heart beat.
Stroke volume
200
An organic acid present in blood and muscle tissue as a product of the anaerobic metabolism of glucose and glycogen.
Lactic Acid
200
Peripheral artery disease can be diagnosed using this.

Ankle-brachial index (ABI). It compares the blood pressure in your ankle with the blood pressure in your arm. Uses Ultrasound machine.

300
 A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos, except for a small number of structures.
Cartilage
300
This type of muscle is dense, contains intercalated discs, and is striated.
Cardiac muscle
300
A condition in which veins become weak, and twisty. Valve do not seem to work and causes fluid accumulation.
Varicose Veins
300
A highly branched polymer of glucose containing thousands of subunits; functions as a compact store of glucose molecules in liver and muscle fibers.
Glycogen
300
Permitting the exchange of nutrients and gases between the blood and tissue cells is the primary function of these.
Capillaries
400
An unbending movement around a joint in a limb (as the knee or elbow) that increases the angle between the bones of the limb at the joint.
Extension
400
The attachment of a muscle tendon to a movable bone or the end opposite the origin.
Insertion
400
List the arteries that branch off of the aorta.
Brachiocephalic, left subclavian, and carotid arteries
400
A technique for temporarily improving athletic performance in which oxygen-carrying red blood cells previously withdrawn from an athlete are injected back just before an event.
Blood Pooling
400
1) Arteries carry oxygenated blood, and veins carry deoxygenated blood, with these two exceptions. 2) What is a better characterization of arteries and veins than whether they are oxygenated?
1) Except for the Pulmonary Vein and Pulmonary Artery. 2) Arteries carry blood away from the heart. Veins carry blood to the heart.
500
Ball-and-Socket, Pivot, Hinge are all example of this category of joint
Synovial Joints
500
The hardening of the muscle and stiffening of the body that begins 3 to 4 hours after death. Explain why this occurs.
Ca++ moves into the sarcomere with passive transport. To leave, they need ATP for active transport. When you die, ATP is no longer available, so Calcium stays attached to the troponin: Rigor Mortis.
500
List the layers of a blood vessel
Tunica adventitia, tunica media, and tunica intima
500
This hormone stimulates red blood cell production.
Erythropoietin (produced by the kidney)
500
These are the three main system that maintain a supply of ATP during exercise, depending on the duration and intensity of the activity.
Phosphagen System, Glycogen-Lactic Acid System, and Aerobic Respiration. Phosphagen System uses creatine phosphate to make energy; for maximum effort and short duration (sprint). Glycogen-Lactic Acid System uses anaerobic espiration to turn glycogen into glucose and ATP; for slower but longer lasting (swimming). Aerobic Respiration uses all remaining glucose, then burns fat reserves, then breaks down proteins; slow but extremely long lasting (marathon).
