Essay on Cardiovascular Disease

1. The autonomic nervous system (ANS) is composed of two parts called the parasympathetic nervous system and the sympathetic nervous system. The parasympathetic nervous system (PNS) is involved with sleeping, digesting meals, and making new blood cells and antibodies. The sympathetic nervous system (SNS) is involved with the “fight or flight” response and is associated with stress. 2. The cardiac output is the amount of blood that is pumped by the heart into circulatory system in the time frame of

The Cardiovascular system, also known as the circulatory system, includes the heart and its vessels. Its purpose is to circulate blood throughout the body and its cells, delivering needed substances and removing waste. The different organs of the cardiovascular system include the heart and its blood vessels, which are capillaries, arteries and veins. There are two parts to the cardiovascular system, pulmonary circulation and systemic circulation. Pulmonary circulation is between the heart and

1. The two main coronary arteries that supply blood to the hart are the left main coronary artery and the right coronary artery. The left main coronary artery provides blood to the left part of the heart (e.g. left atrium and left ventricle). In particular, the left main coronary branches off into the circumflex artery and the left anterior descending artery. If there is occlusion in the circumflex coronary, then there is infarction in the left atrium and the side and back of the left ventricle

Tricuspid Valve The tricuspid is found in the right side of the heart. It rests between the atrium and the ventricle. The function of this valve is to make sure that blood flows in the correct direction, forward, from the atrium to the ventricle. This is important to make sure that blood doesn't move backwards through the heart. When blood flows backwards through the heart it is referred to as regression or tricuspid regurgitation. Pulmonary Valve The pulmonary valve is found to the right side

There are two primary circulation loops in the human body known as pulmonary circulation loops and systemic circulation loops. o Pulmonary circulation loops: is responsible for transporting oxygenate-poor blood from right atrium, to the right ventricle and then to the lung. The blood then picks oxygen in the lung and then returns to the left atrium. o Systemic circulation loops: then systemic circulation loops transport the oxygenate-rich blood from the left atrium to then left ventricle. From

Single celled organisms are small meaning that their surface area is big compared to their volume. These organisms have a large surface area to volume ratio which means that they can obtain different substances by diffusion through their relatively large plasma membrane. The substances have to diffuse only short distances so they can diffuse at a faster rate and meet the organism’s needs. Multi-cellular organisms have a much smaller surface area to volume ratio. Many of their cells are not in direct

The different between the different routes is that the fatal circulation is a circulation of blood that passes through the body of the fetus and to and from the placenta through the umbilical cord. The Portal circulation is a general term of denoting the circulation of blood through a larger vessel from the capillaries of one organ to those of another that also applied especially to the passage of blood from the gastrointestinal tract, pancreas, and the spleen through the portal vein to the liver

Every system is connected to each other, in different many ways. In our project microbe an us blood is the number one survival in the circulatory system,. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems.In our heart we have a pulmonary circulation is a short loop that goes from the heart to the loops and goes back again. The muscular system connects to the circulatory system. The muscular

Intro: The heart has a clear function, which is to constantly pump blood through the body into every organ that consists of cells. Blood is transported through the body with veins and arteries that are set up through the body, one having oxygenated blood flowing into the body while the other is poor on oxygen heading into the lungs for gas exchanges. These pumps the hearts emulates are caused by electrical stimulation, which produce muscle contraction. The cardiac cycle has a regular pattern that

The capillary exchange is where necessary gases and molecules move between the plasma and the interstitial fluid. Both hydrostatic pressure and osmotic pressure contribute to this, as they help fluids move in and out of capillaries and through diffusion. Arteries carry blood to the body organs and tissues, and once they reach an organ, branch into small branches called arterioles. These arterioles then branch into capillaries, thin-walled blood vessels, that due to their thin walls are best suited
