<u>Excretes waste:</u> The excretion process, is done mainly by lungs (release of carbon dioxide), kidneys (elimination of excess compounds such as nitrogen) and the skin (sweat regulates temperature but also regulates the concentration of salts within the body)

<u>Nails:</u> It protects the soft tissues surrounding the distal phalanx, but it also exerts pressure over on the digits which allows more precission in the movements.

<u>Kidneys:</u> Eliminate waste from the blood and regulate body fluids, by generating urine.

<u>Bladder:</u> In charge of storing the urine produced by the kidneys, for the urination process to be controlled and not so frecuent.

Hich physiologic change increases cardiac work but does not enhance cardiac output?
Ugo [173]

Increased afterload physiologic change increases cardiac work but does not enhance cardiac output.

<h3>What about cardiovascular system?</h3>
  • Heart and blood vessels, which make up your cardiovascular system, deliver oxygen and nutrition to your body's organs so they can function.
  • Blood vessels also transport waste such as carbon dioxide to be disposed.
  • Conditions affecting the heart or blood vessels are collectively referred to as cardiovascular disease.
  • It is frequently associated with atherosclerosis, an accumulation of fatty deposits in the arteries that increases the risk of blood clots.
  • The heart, blood arteries, and blood make up the cardiovascular system.
  • Its main job is to carry deoxygenated blood back to the lungs and to carry nutrients and oxygen-rich blood to all regions of the body.
  • The most typical cause of coronary artery disease is atherosclerosis, which is a buildup of fatty plaques in your arteries.
  • Atherosclerosis can be brought on by unhealthy lifestyle choices such smoking, being overweight, not exercising, and eating poorly.

The smooth but steady increase in muscular tension that is produced by increasing the number of active motor units is called ___
Troyanec [42]

The smooth, but steady, increase in muscular tension produced by increasing the number of active motor units is called a recruitment.

Muscle tension is the force produced when a muscle contracts (or when sarcomeres shorten). The two primary forms of skeletal muscle contractions, isotonic contractions and isometric contractions, are produced when a muscle contracts against a load that is not moving.

  1. A load is transported as the length of the muscle varies during isotonic contractions, in which the tension in the muscle remains constant (shortens). Concentric and eccentric contractions are the two varieties of isotonic contractions.
  2. When a muscle contracts isometrically, the angle of a skeletal joint remains the same while tension is produced in the muscle. Sarcomeres shorten and muscles tense up during isometric contractions, but the load is not moved since the force generated is insufficient to overcome the resistance provided by the load.
