Transportation has many roles in the cardiovascular system. First, our blood carries oxygen from our lungs to all of our tissues. While taking oxygen to our tissues, it also picks up carbon dioxide from them and takes it to our lungs to be removed from our body. Second, it delivers nutrients from our digestive tract to all of our body’s tissues. Third, it takes waste to our kidney’s to be removed from our body. Fourth, it
I am going to explain the physiology of the respiratory and cardiovascular system in relation to the energy metabolism in the body.
The cardiovascular system The heart is a major organ in the body, this organ pumps blood around the body, through veins, capillaries and arteries. The blood carries oxygen to our cells and also carries waste products which include water and carbon dioxide, which are products of respiration. Blood also helps

The S-A node signal is delayed by the atrioventricular node to allow the full contraction of the atria that allows the ventricles to reach their maximum volume. A sweeping right to left wave of ventricular contraction then pumps blood into the pulmonary and systemic circulatory systems. The semilunar valves that separate the right ventricle from the pulmonary artery and the left ventricle from the aorta open shortly after the ventricles begin to contract. The opening of the semilunar valves ends a brief period of isometric (constant volume) ventricular contraction and initiates a period of rapid ventricular ejection.
Age Related Changes that Occur in the Cardiovascular System Age Related Changes that Occur in the Cardiovascular System In the normal conduction of the heart the electrical impulse starts in the SA node, also called the pacemaker of the heart. The electrical impulse travels through the right atrium and through the Bachmann’s bundle into the left atrium. This stimulates the atria to contract. Next the signal travel to the AV node. The AV node slightly delays the signal. This delay is needed for the heart to beat properly. Without this delay the atria and ventricles would beat at the same time. The electrical signal then travels to the Bundle of His where it is split into the signals going to the right and left ventricle. The signal
The blood flow both the pulmonary and systemic circuits in humans The cardiovascular system is made up of two circulatory routes, the pulmonary circuit and the systematic circuit. The blood is oxygenated in the lungs during the pulmonary circuit and then the oxygenated blood is circulated through the rest of
P5 describe the structure and function of the cardiovascular system Function of the cardiovascular system The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.
Arteries They are blood vessels that carry blood away from the heart which is a lot of the oxygen.
There are three main types of blood vessels: arteries, veins, and capillaries. Arteries are vessels that usually carry highly oxygenated blood away from the heart and to the rest of the body. (The pulmonary trunk and related arteries are exceptions, as they actually carry blood from the lungs toward the heart.) Because arteries must transport high volumes of blood being forcefully pumped out by the heart and must therefore withstand greater pressure, most have thick, muscular walls and are more flexible as well. Arterioles, smaller types of arteries with thinner walls, branch off of the arteries to carry blood to another type of vessel, called the capillary. Capillaries are the most abundant blood vessels in the body. Thinner and smaller than the other blood vessels, the role of capillaries is to exchange substances like water, gases, chemicals, nutrients, wastes, etc. with the tissues of the body. The third type of blood vessel is the vein. Although they are generally larger than the other blood vessels, veins tend to have thinner, less flexible walls, as they are not forced to deal with such high blood pressures. Venules (veins’ versions of arteries’ arterioles) connect the capillaries to the veins, which then transport blood back
On the right side the flow of blood enters the heart through the inferior and superior vena cava that throws out the poor oxygen blood to the right atrium. On the left side of the heart the pulmonary veins takes action that dumps the rich oxygen blood that is coming from the lungs to the left atrium. This has both sides of the heart working together. When it comes to the atrial contraction, the right side makes the blood flow to the right atrium to the right ventricle to the tricuspid valve. Once the ventricles fill up completely, that is when the tricuspid valves shut closed. This is to prevent the blood from going backwards to the atria, making the ventricles squeeze together. The left side of the atrial contraction makes the blood flow from
To reach the body, the oxygen filled blood has to travel through the arteries. The arteries are
Tricuspid valve: The valve between the right atrium and the right ventricle is called the tricuspid valve. This valve opens to allow blood to be pumped from the right atrium in to the right ventricle. Once the blood has passed through the valve closes so the blood cannot pass back. The name tricuspid comes from the fact that it has three
When blood with a small amount of oxygen arrives into the lungs, it gets rid of carbon dioxide and replaces it with oxygen. When blood enriched with oxygen it goes back to the heart through the pulmonary veins. After it leaves the lungs, it arrives to the left atrium. When the left atrium shrinks, the rest of the blood in it is pushed through the bicuspid valve into the left ventricle.
The vessels main purpose is to transport blood from the heart too the various tissues throughout the body.
