<h2>Answer 13:</h2>

Affect of exercise on the circulatory system:

  • Exercise improve the circulation of blood throughout our body.
  • This provides the muscles with the necessary oxygen and nutrients to provide the muscles with energy.
  • The systemic circulatory system includes blood vessels that deliver oxygen and nutrient-rich blood to tissues throughout your body.
<h2>Answer 14:</h2>

Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.

  • Ventilation is the process that moves air into and out of the alveoli, and perfusion affects the flow of blood in the capillaries.
  • External respiration refers to gas exchange that occurs in the alveoli
  • whereas internal respiration refers to gas exchange that occurs in the tissue.

Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Fantom [35]

Answer:

Correct

Explanation:

Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.

The Homoeostatic feedback mechanism has three basis components and they are independent to one another.

These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.

So, the order  in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.
