Heart rate is the measure of the hearts electrical system. Electrical impulses automatically are generated by special cells in a node at the top of the heart called the SA (Sinoatrial) node. These electrical pulses stimulate the heart muscle and cause it to contract. In turn, the heart contracts and moves the blood throughout the heart. There are 9 pulse points throughout the body. The most common is the one your feel on your wrist.

Normal heart rate is between 60-100 beats per minute (bpm)

For heart rates above or below these values, your health may be adversely affected depending on your health or physical condition.

If your heart rate falls out of this range. Its best to check with your doctor immediately if you suspect a problem with your heart.

What is homeostasis and how does stress affect homeostasis?

Homeostasis is the body's ability to maintain stable internal conditions despite external changes. Stress can disrupt homeostasis by triggering the release of stress hormones like cortisol, which can lead to imbalances in physiological processes such as heart rate, blood pressure, and immune response. Prolonged stress can negatively impact overall health by taxing the body's ability to maintain homeostasis.

What subdivision of the PNS regulates the activity of the heart?

The subdivision of the peripheral nervous system (PNS) that regulates the activity of the heart is the autonomic nervous system (ANS). Specifically, the sympathetic division increases heart rate and contractility, while the parasympathetic division, primarily through the vagus nerve, decreases heart rate. Together, these divisions help maintain homeostasis in cardiac function.


What does the autonomic reflex involved?

The autonomic reflex is involved in controlling involuntary bodily functions such as heart rate, digestion, and respiratory rate. It helps maintain homeostasis by responding to changes in the internal and external environment without conscious effort.

How does thyroxine contribute to homeostasis?

Thyroxine is a hormone produced by the thyroid gland that regulates metabolism, heart rate, and body temperature. By controlling these key physiological processes, thyroxine helps maintain overall homeostasis in the body by ensuring that the internal environment remains stable and balanced.


Why do you have a heart rate?
