Heart Homeostasis

Inside our body there is a powerful muscular pump, which is known as the one of the main organs in the human body. This hollow, cone shaped, pump lies slightly left within the center of the chest called our heart. The heart is made up of different structures and actions in order for it to work, combined with a network of blood vessels form what we know as the cardiovascular system.

Now, let's talk how the heart works. The heart is divided into two halfs. Each side has a upper and a lower chamber. The upper right chamber revives poor-oxygen blood from the body. The lower right chamber pumps

The heart is a muscular organ that rests behind the sternum. The heart pumps blood through a network of arteries and veins that makeup the cardiovascular system. (The Heart (Human Anatomy)

Table 1. This table shows the recording of the amplitude, period, and BPMs for the ventricular contractions before and the effects of the Cold Ringer’s after.

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

heart from the body by the veins and its purpose is to keep us alive

he first part of the experiment, exercise 1, dealing with heart rate and temperature can be seen in Table 1. It was apparent that temperature decreased the heart rate and this was probably due to same principles surrounding nerves. If the temperature is too low it is harder for ions to pass through the membrane and cause an action potential thus decreasing the contraction of the heart. The visual representations of this exercise can be seen in Figure 1 (before cold ringers) and Figure 2 (after cold ringers).

The central organ of the Cardiovascular System is the Heart, the muscular organ pumps blood through an intricate network of Blood Vessels to all parts of the body. The heart sends blood around the body. The blood provides the body with the oxygen and nutrients it needs. It also carries

The heart is responsible for moving the body’s blood, and is primarily composed of cardiac muscle. Similar to skeletal muscle, the cells are

The function of the heart is to pump blood around the body. It is a hollow muscle and can

There are many factors that can affect your heart rate. Some factors that can speed up or slow down the heart rate is stress, illness, sounds, medication, exercise, etc. For example, with

As everybody knows, the function of the heart is to pump blood throughout your body. You may be wondering how it does that though. I’ll explain how the heart works.

The heart is one of the body’s most important organs and is composed of a tissue known as cardiac muscle which has developed over time to pump blood throughout the body. Over an organism’s lifetime, the heart will beat continuously and powerfully without any rest so cardiac muscle has evolved to have incredibly

Without a heart in its body, a living organism would not survive. However, not every single heart is the same. Doyle uses two different animals to explain how their heart functions; hummingbirds and blue whales. The author explains each animal’s heart in depth, and discusses what goes on inside of their bodies. By comparing these two animals and

The heart is described as the most valuable organ in the body. The function of the heart is to pump blood throughout the body. The heart works to pump and circulate all of the materials our body needs to operate properly. The right side of the heart receives de-oxygenated blood from the body. The blood rides through the Tricuspid Valve into the Right Ventricle. After that, it pumps through the Pulmonary Valve into the Pulmonary Artery. This is where the de-oxygenated blood is taken to the lungs to get oxygen.
