skeletal system
how many bones are in the adult human body
206
what is a joint
where two or more bones meet
what connects muscles to bones
what organ pumps blood around the body
heart
what is the body's main source of energy
ATP (adenosine triphosphate)
what is the longest bone in the body
femur
what type of joint is the knee
what is the largest muscle in the body
gluteus maximus
what are the blood vessels that carry blood away from the heart
arteries
which energy system is used for very short, explosive activities like a 100m sprint
ATP-PC system
what is the main function of the skeleton
support, protection, and movement
what type of joint is the shoulder
ball and socket joint
what muscle pumps blood around the body
heart (cardiac muscle)
what is the main function of the cardiovascular system
transport oxygen, nutrients, and waste
which energy system is mainly used during a 400m run
anaerobic glycolysis (lactic acid system)
which bone protects the brain
skull
which joint allows the greatest range of movement
what are the three types of muscle tissue
skeletal, smooth, and cardiac
what is the name of the blood cells that carry oxygen
red blood cells
which energy system is used during a marathon
Aerobic system
name three functions of the skeletal system
support, protection, movement, blood cell production, mineral storage
name three types of joints
hinge, ball and socket, pivot and gliding
what is the function of muscles
to create movement, maintain posture, and produce heat
what happens the the heart rate after exercise
it increases to deliver oxygen to muscles
put these three energy systems in ordered from shortest to longest distance
ATP-PC, Aerobic, Anaerobic Glycolysis
ATP-PC - Anaerobic Glycolysis - Aerobic
