The target heart rate zone is the range of exercise intensity that allows you to stress your cardiorespiratory system for optimal benefit without overloading the system.
The target heart rate of an individual refers to the heartbeat range during exercise and is measured as a percentage. The resting heart rate is calculated by checking the pulse beat for one minute. It normally ranges between 60-100 beats/minute. The target heart rate is 220 subtracted by the age of an individual. For example, the target heart rate for a 27-year-old would be 220-27= 193 beats/minute. Therefore, at a 50% exertion level, the target heart rate must be 50% of the maximum value, that is, 97 beats/minute.

In radiology and nuclear medicine, single - photon emission therapy (PET)/computed tomography (CT) scanning is now a standard practice.
<h3>What distinguishes a CT scan from a PET scan?</h3>
The internal organs and tissues of your body are depicted in great detail by a CT scan. A Pet / ct can be more accurate than some other imaging procedures and can detect aberrant activity. Additionally, it can cause your body to alter sooner. PET-CT scans are used by doctors to reveal more details about the cancer.
<h3>What distinguishes an MRI from a PET scan?</h3>
Radio waves and magnets are both used in magnetic resonance imaging (MRI) studies. Both generate static photos of the body's organs and skeletal system. Using a radioactive tracer, PET scans can demonstrate how an organ is working in real time. CT and MRI scans cannot identify cellular responses in tissues and organs as early as PET scan images can.

Answer:
The different functions of the nervous system are to:
- Control of body's internal environment to maintain 'homeostasis' An example of this is the regulation of body temperature. ...
- Programming of spinal cord reflexes. An example of this is the stretch reflex. ...

- Voluntary control of movement.
The exocrine pancreas and major salivary glands are compound exocrine glands—specialized secretory organs that contain a branching ductular system through which they release their secretory products. The principal function of these exocrine glands is to aid in the digestion of food.
