Body & Energy Systems Flashcards
What are the five functions of the heart?
— Circulates blood to all parts of the body.
— Transports water, oxygen, and nutrition to cells.
— Transports waste including carbon dioxide away from cells.
— Helps maintain correct body temperature.
— Helps fight diseases through white blood cells and antibodies.
What are three parts of the cardiovascular system?
— Pumps blood around the body
— Deoxygenated blood
— Oxygenated blood.
List of the 9 steps of the pathway of blood.
- Deoxygenated blood travels through the inferior ad superior vena cava.
- Blood is collected in the right atrium.
- Blood moves through the tricuspid valve into the right ventricle.
- Pumps through the pulmonary valve into the pulmonary artery to the lungs.
- Collects oxygen and releases carbon dioxide.
- Takes oxygenated blood back through pulmonary veins.
- Blood enters the left atrium, then pumps through the biscupid valve.
- Blood enters the left ventricle.
- Pumped into the aorta and distributed around the body.

What are the functions of the respiratory system?
Brings air into the lungs
Transfers 02 into the blood
Removes C02 from the blood
Expels heat and water from the air breathed out
List the parts of the respiratory system.
— Trachea
— Bronchus
— Bronchi
— Bronchioles
— Alveoli
— Lobes
Gas exchange that occurs in the alveoli.
Microscopic cup-shaped sacs at the end of the bronchioles.
Only one cell thick and surrounded by capillaries.
Continually exchanging 02 for C02 and H20 within the bloodstream.
What is the ATP-PC system also known as?
Phosphocreatine Energy System
What is the Anaerobic Glycolysis system also known as?
Lactic Acid System
What is the Aerobic system also known as?
— Oxidative Energy System
— Oxygen Energy System
What is the intensity of the ATP-PC system?
Very high intensity (95-100% of MHR)
What is the intensity of the glycolysis system?
High intensity (85% of MHR)
What is the intensity of the aerobic system?
Low intensity (60-70% of MHR)
What is the duration of the aerobic system?
Long in duration (60+ seconds)
What is the duration of the glycolysis system?
Short in duration (10–60 secs)
What is the duration of the ATP-PC system?
Very short in duration (0-6/10 secs)
What is the peak power of the aerobic system?
1-1.5 minutes.
What is the peak power of the ATP-PC system?
2-4 seconds
What is the peak power of the glycolysis system?
5–15 seconds
What is the amount of ATP produced for the aerobic system?
36 ATP
What is the amount of ATP produced for the glycolysis system?
2 ATP
What is the amount of ATP produced for the ATP-PC system?
1 ATP
What is the speed of ATP recovered for the ATP-PC system?
The fastest, explosive, relies on simple chemical reactions to create ATP.
What is the speed of ATP recovered for the glycolysis system?
High, longer chemical reactions in a break-down of glycogen compared to the ATP-PC system.
What is the speed of ATP recovered for the aerobic system?
Slow, the slowest rate of ATP resynthesis.
List the by products of the ATP-PC system.
— Inorganic Phosphate (Pi)
—Adenosine diphosphate (ADP)
List the by products of the glycolysis system.
— Lactic Acid
— Hydrogen ions (H+)
— Adenosine Diphosphate (ADP)
