Heart, lungs and the Rest of You
By: Olivia Abel
1.Explain how the blood flows throughout your lungs, heart and the rest of your body.
Heart:
Your left and right side of your heart work together to pump blood to and throughout your body which is separated by muscular tissue called the septum. In the right side blood enters through two large vein which are the inferior and superior vena cava, emptying poor oxygen blood from the body to the right reticulum. When the left side enters from the pulmonary veins and empties oxygen rich blood from the lungs into the aorta going throughout the body. There are three main types of blood vessels that help blood flow through your heart. They are
Arteries -
They carry oxygen rich blood away from the heart to all of your body tissues. Which get smaller and smaller the farther they get away from the heart.
Capillaries -
Which Are small thin blood vessels that connect the arteries and the veins together. There thin walls allow oxygen, nutrients and carbon dioxide to pass through and from cells.
Veins -
They are blood vessels that take blood back into the heart.
2. After leaving the heart, blood goes to the lungs, where it collects oxygen. this , goes back into the heart from the lungs, and is pumped to organs through arteries. The blood returns to the heart through the

All or parts of the heart muscle becomes cut off from its oxygen supply. Left without oxygen.To the heart muscle is injured. Your heart becomes damaged and will most likely take awhile for recovery and for your body to go back to its normal state. Many people survive their first heart attack, this is 50 to 75% of people. After the heart attack, your heart will most likely go back to normal or it could become a region of dead heart tissue. Heart attacks could also cause weakness of the blood being flown in through the heart, making it much easier for you to have shortness in
The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.
Arteries deliver oxygenated blood to the capillaries, where the exchange of oxygen and carbon dioxide takes place. An artery's muscle helps it expand and contract in rhythm with the heart beating to keep blood moving through the system. Capillaries connect veins and arteries to exchange oxygen and carbon dioxide. Thin and weak, capillaries are only as thick as one epithelial cell. Blood passes through capillaries one cell at a time, single file.
The lung tissues may develop a pneumothorax. This causes the lungs to collapse by letting air escape into the chest cavity. This disease may affect the heart through aortic dilation. The aorta is a blood vessel that is responsible for transporting blood from the heart to the body. In aortic dilation, the aorta may overstretch or become weak.
Normally blood entering the right side of the heart stays on the right side (this is low-oxygen blood), and blood on the left side of the heart stays on the left side (this is oxygen-rich blood) which is then pumped to the rest of the body. But in this particular condition when a defect or "hole" is present between the ventricles (or lower chambers), blood from the left side of the heart is forced through the defect to the right side every time the heart beats. It then goes back to the lungs even though it is already rich in oxygen. Because of this, blood that is not yet oxygen-rich can 't get to the lungs. The most common signs and symptoms are trouble eating and gaining weight, breathlessness and easy fatigability in
The walls of veins are far thinner and the lumen passage much larger. The walls are not muscular and blood is pushed through the vessels by the action of skeletal muscles. Veins carry deoxygenated blood (dark red) to the heart, except for the pulmonary veins which carry oxygenated blood. Blood pressure is very low in the veins, so there are valves in the endothelial layer which prevent the back flow of blood (Tucker, 2015).
Systolic and Diastolic Heart Failure Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart 's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart 's pumping power, so it 's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood.
Mitral valve regurgitation is one of the few heart conditions you may unknowingly have for years and learn to live with the affects of this condition before ever being diagnosed. Mitral valve regurgitation occurs when the mitral valve is letting blood leak backward into the upper chambers of the heart. The mitral valve is located between your heart’s two left chambers . Mitral valve regurgitation, or mitral insufficiency as it is known, is a common heart valve disorder.
The heart has four valves which help the blood flow. There are 5 main types of blood vessels that enter and leave the heart. Hypothesis If the heart is pumping the blood through the body, then it is connect to the vascular system. The vascular is also called cardiovascular systems that contains blood vessels and lymph through the body.
Because of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.
Then the blood passes through the mitral valve, also known as the bicuspid valve, into the left atrium. Similar to the tricuspid valve, the mitral valve is also a one-way valve that prevents backflow of the heart. In the last chamber of the heart, the left ventricle will pump the oxygenated blood through the aortic valve into the aorta, which will then distribute the blood through our body. Congestive heart failure is divided into left and right sided heart failure. Left sided heart failure is caused by the left ventricle not being able to pump blood out effectively.
Due to the recent statistics, lung cancer has been known to be increasing twice as much in women than in men. Staying away from tobacco is the most important thing any of us can do to avoid getting lung cancer. There have been many cases of lung cancer as thousands of people are dying annually. Lung cancer would rank among the top 10 fatal cancers in Canada, since many people fail to realize the importance of maintaining a healthy body, most specifically lungs. Lungs are one of the key organs in our body.
Vesalius had observed, by dissection, that there were no pores in the septum of the heart. This meant that direct transfer of blood was not possible. Harvey’s explanation for how blood was transferred from the right ventricle to the left ventricle was that it went through the lungs via the pulmonary arteries and returned through veins to the left auricle, and subsequently to the left ventricle. Once again this description was a simplified explanation of flow in line with his observations and those of Vesalius and
Myocardial Infarction which is another word for Heart-attack. When you have an heart-attack your blood is not getting to your heart's muscle. This means your arteries are clogged. Blood is pumped through your arteries to all of the parts in your body. If you have a heart condition you shouldn't smoke, you should diet and exercise, you should watch your Blood Pressure if you have to take medication for your Blood Pressure make sure you take the prescribed medication.
The objective of this experiment is check how heart chambers, vessels and valves of the heart help the heart to achieve its function of pumping blood all over the body. In addition, this experiment would help us understand the double circulation of blood and reasons why it is vital for mammalian organisms. Due to the complexity of mammalian organisms, the exchanges of substances such as oxygen, nutrients and hormones cannot rely on diffusion itself (Kent, 2013). The transportation
The human body is made up of complicated physiological processes, one of them being the process of transporting blood around the body by a system known as the circulatory system. This system carries blood around the body from the heart to the organs, tissues and cells of the body. Blood is made up of blood cells, namely erythrocytes, thrombocytes and leucocytes – in an extracellular matrix called plasma, which makes up approximately 55% of the blood. It is essential that blood is transported to the organs and systems of the body in order for these systems to function. The fluid is transported through blood vessels known as arteries, veins and capillaries in a succession starting and ending at the heart.
