How would homeostasis be affected if the cardiac muscle stopped contracting?

1 answer:

4 0

The heart is a muscle, therefore, if the cardiac muscles stopped contracting, the result would be the ceasing of heart function. That would lead to death, as blood wouldn't be pumped throughout the body. Homeostasis would therefore be interrupted.

Which seismic waves are felt first at a seismic station

vlabodo [156]

Question-
Which seismic waves are felt first at a seismic station

Answer-
Seismic waves are the waves of energy caused by the sudden breaking of rock within the earth or an explosion. They are the energy that travels through the earth and is recorded on seismographs.

There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.

BODY WAVES
Traveling through the interior of the earth, body waves arrive before the surface waves emitted by an earthquake. These waves are of a higher frequency than surface waves.

P WAVES
The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to 'arrive' at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. It pushes and pulls the rock it moves through just like sound waves push and pull the air. Have you ever heard a big clap of thunder and heard the windows rattle at the same time? The windows rattle because the sound waves were pushing and pulling on the window glass much like P waves push and pull on rock. Sometimes animals can hear the P waves of an earthquake. Dogs, for instance, commonly begin barking hysterically just before an earthquake 'hits' (or more specifically, before the surface waves arrive). Usually people can only feel the bump and rattle of these waves.

P waves are also known as compressional waves, because of the pushing and pulling they do. Subjected to a P wave, particles move in the same direction that the the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'.

Nervous system. It uses nerves to transmit messages through the body and responds to action in the outside environment. Its major organs are the brain, peripheral nerves and spinal cord. It works closely with skeletal system and muscular system.

Cardiovascular system. It regulates body temperature, fights infections, removes cell waste and it brings oxygen to cells. Its major organs are arteries, veins, heart, and blood vessels. It interacts with the digestive system to help red blood cells to carry nutrients and digested food in the body. It reacts with endocrine which helps red blood cells to carry hormones which deliver a message to the body.

Respiratory system. Its work in the body helps in breathing.Its major organs are lungs, pharynx and nose.works closely with immune, excretory system and circulatory system.

Muscular system. Helps in the circulation of foods and blood and allows it to produce voluntary movement.Its major organs are cardiac muscles, smooth and skeletal muscles.

Digestive system. It absorbs and converts food into molecules for cell use and it also helps in elimination of solid waste. Its organs are mouth, stomach, and intestines. It interacts with cardiovascular and excretory systems.

Urinary system. It helps in elimination of salt, excess water, and body waste. Its organs are bladder, urethra, urinary tract, and ureterus. It reacts with the nervous system where bladder sends sensory into the brain and then brain control urination.

Endocrine system. It maintains homeostasis and controls growth and development through hormones. Its main organs are testes, ovaries, and glands. It works closely with reproductive, digestive, nervous, and cardiovascular.
