The cardiovascular system 2 essay

The left and right sides of the heart are divided by a muscular wall of tissue known as the septum of the heart. The various dissolved substances like oxygen, food, etc. The terms superior and inferior does not mean that one vein is better than the other vein, but that they are located above and below the heart.

The bicuspid, or mitral, valve prevents the blood from flowing back into the atrium, and the semilunar The cardiovascular system 2 essay at the beginning of the aorta stop it from flowing back into the ventricle. This can be explained as follows: Veins have valves in them which allow the The cardiovascular system 2 essay in them to flow in only one direction towards the heart.

If necessary, the bacteria collected through this direct methodology will be cultured in an appropriate lab setting using standard equipment, with twenty-four hours being sufficient time for the culture to grow to be identifiable in most instances.

The valves prevent the backflow of blood in veins. Such contractions may result in the movement of the whole body or a portion of it, which is if the muscles are attached to a movable part of the skeleton. The animals such as mammals including human beingsand birds have four-chambered heart which consists of two atria and two ventricles.

The lifespan of the cells is about three or four months, once they have aged or become damaged they are subsequently removed from the bloodstream by the spleen. The second point to remember is that when blood circulates in the body, then it supplies oxygen, digested food and other chemicals like hormones to all the cells of the body.

Please note that the two atria left atrium and right atrium contract together and relax together. There are four chambers that enclose the heart with thick muscular walls.

Red blood cells also contain a substance called hemoglobin. Examination of bacteria types, growth patterns in the mouth, and correlation with cardiovascular disease will be identifiable with the data collected via these methods, enabling appropriate analysis and a determination of correlation.

Veins are also found in the whole of our body. Carbon dioxide from the organs and tissues diffuses into the red blood cells just as oxygen diffuses out of the red blood cells. Arteries, veins and capillaries are called blood vessels.

The blood also gives the digested food and other dissolved materials to the body cells. In this way, the blood keeps on circulating in our body without stopping due to which all the body parts keep on getting oxygen, digested food and other materials all the time.

The chambers of the heart are separated by a partition called septum. Over 60 million cases have been diagnosed in the US Ninety percent of these cases are primary-essential, idiopathic, that is there is no known cause.

However, problems do arise and there are many conditions and disorders of the cardiovascular system.

This whole process is repeated continuously. This tissue can be found in the walls of arteries, veins, and capillaries, and, of course, in the makeup of the heart.

Short essay on Human Circulatory System

We will now describe all the parts of the circulatory system in detail. Hemoglobin are small molecules found within red blood cells that give the blood its rich red color. Arteries are found in the whole of our body. Without the cardiovascular system our body would not be supplied with the necessary substance to stay alive.

The pulmonary artery divides into left and right branches from the right ventricle, en route to the lungs where blood gains oxygen. Vasoconstriction decreases the diameter of an artery by contracting the smooth muscle in the arterial wall.

Vasodilation is the expansion of an artery as the smooth muscle in the arterial wall relaxes after the fight-or-flight response wears off or under the effect of certain hormones or chemicals in the blood. Platelets normally remain inactive in the blood, that is until they reach damaged tissue or leak out of the blood vessels through a wound.

The flow of blood in a fish is called single circulation because the blood passes through the heart of fish only once in one complete cycle of the body.The cardiovascular system is made up of the heart, blood vessels and blood.

The heart is a myogenic muscle, meaning that it can contract without any nervous supply. It is composed of cardiac muscle which is built up of cells that are connected by cytoplasmic bridges, allowing electrical impulses to cross.
