Answer:

a) Increased heart rate, increased blood pressure, increased respiration rate.

Explanation:

When a person do any physical activity like running, jogging, cycling, swimming and stair climbing, the heart rate, blood pressure and respiration rate of a person are increased because due to physical activity, the body needs more and quick oxygen and energy. This oxygen is provided by heart through pumping of blood and energy is released due to the breakdown of glucose molecules that occurs in mitochondria of the cell in the process of respiration. For providing oxygen and energy quickly, blood pressure of the body is increased.

Katarina [22]
<h2>Answer 1 with Explanation </h2>

The nervous system help the body to respond to different stimuli because its function is to coordinate with all the body parts. It has four primary functions that relate to the areas of the body in every human being for which the system handles information. The sensory function allows the body to collect information from outside or within the body.

<h2>Answer 2 with Explanation </h2>

Tom steps into the haunted house- the brain receives information from different parts of the brain and interprets it to generate the emotion of fear and then sends impulses to different parts of the body to trigger a flight response. Organisms that fear and make a flight response are more likely to survive. Later then the nervous system interprets the information to the brain through the spinal cord.

<h2>Answer 3 with Explanation </h2>

Tom feels his heart pumping and his breathing speed up because of the sympathetic nervous system stimulates adrenal glands that trigger and releases adrenaline which results in an increase in heart rate, blood pressure, and breathing rate. The integrative function is about how the collected information is being interpreted in Tom.

<h2>Answer 4 with Explanation </h2>

Tom jumps when he sees the costumed character. This is due to flight response in an individual, unleashes powerful hormones are released that affect the whole body from which signals are transferred to the brain and then it causes an involuntary jump in the muscles of the individual. The reasoning of this is that Tom's brain responses in a shock when he sees the character.

<h2>Answer 5 with Explanation </h2>

Tom runs out of the haunted house The reason of this is that Tom runs when the brain makes his muscles move by sending electrical signals to them through the nerves and this kind of involuntary actions happen really quickly so that the action takes place faster. At last, the nervous system helps to determine the motor function in which the effectors are able to respond.
