Tigers Cardiovascular System
Tigers and humans seem very different. However there is one system within the body that are similar between the two. The cardiovascular system of a tiger and a human are similar when it comes to the heart. Oxygenated blood makes its way to the heart in the same way as it does for a human. Although these two beings seem very different, looking at the cardiovascular system will say otherwise.
A tiger heart is like a human 's heart. Veins carry blood from the body to the right atrium then blood is stored in the right atrium until being pumped into the right ventricle. The right ventricle pumps the blood into the lungs and then it is fused with fresh oxygen. The largest muscle in the heart that is located in the left ventricle, pumps the freshly oxygenated blood to all other organs and body parts. Then blood is circulated and exhausted, veins carry it back toward the heart and the right atrium to begin the process again. A human 's heart has two atria and two ventricles. The atria distributes oxygenated blood. The right atrium takes in oxygen and poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen and poor blood to the lungs. The left atrium receives oxygen and rich blood from the lungs and pumps it to the left ventricle. That is how a tigers and human heart pumps blood.

In a human blood that is lacking oxygen is deoxygenated blood. This is called Pulmonary circulation. This blood has exchanged oxygen for carbon dioxide across cell membranes and it contains mostly carbon dioxide. Deoxygenated blood enters the right atrium through the superior vena cava and the inferior vena cava. In a tiger 's heart it pumps oxygenated blood to the body and then it pumps deoxygenated blood to the lungs to become oxygenated. Ventricles pass deoxygenated blood to the pulmonary artery and then on the lungs left ventricle. The aortas bring deoxygenated blood to the lower body, right atrium, head, and
Unit V Cardiovascular System
760 Words | 4 PagesPathophysiology The present of a patent foramen ovale is required to permit blood flow across the septum into the left atrium, the patent duct arteriosus allows blood to flow to the pulmonary artery into the lungs. VSD allows a modest amount of blood to enter the right ventricle &pulmonary artery. Thus pulmonary blood flow is diminished.
Northern Pintail: Skeletal System
1436 Words | 6 PagesThe 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.
Abraham Lincoln Marfan Syndrome
981 Words | 4 PagesThe 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.
Atrial Septal Defect Essay
1039 Words | 5 PagesNormally 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
Tiger Sharks Research Paper
1182 Words | 5 PagesSharks are enormous mammals that live within the deep ocean waters all over the world. There are several different sharks in many parts of the world depending on temperature, seasons, food and more. Every shark is unique in their own way and every species is unique as well. Although humans view them as vicious creatures that are out to harm us while we are at the beach on a sunny Sunday, these creatures are just trying to live like any other animal in this planet. They each have different defense mechanisms, and physical features that all them to live and continue reproducing.
Explain How The Blood Flows Between The Lungs And The Rest Of The Body
911 Words | 4 PagesHeart, 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.
Diastolic Heart Failure
1517 Words | 7 PagesSystolic 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.

1383 Words | 6 PagesIf a person does not have a cardiovascular system that is in good working order, it can be a fatal situation. Along with pumping blood to the body, the cardiovascular system also brings oxygen and nutrients to all of the different organs and tissues within the body. As our blood makes its circuit journey from the heart to the extremities and then back to the heart, waste is removed from the cells as well. For the cardiovascular system to function at an optimal level, it needs to be healthy and fit.
Heart Failure Research Paper
952 Words | 4 PagesThe left ventricle is the primary pumping chamber, and heart failure normally begins on the left side. At the point when the left ventricle can't contract enough, it is called systolic heart failure. At the point when the left ventricle can't load with enough blood, it is called diastolic heart failure. You can have a blend of both sorts of heart
Case Study Cardiogenic Shock
1075 Words | 5 PagesBecause 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.
Summary: Skeletal Muscles
1789 Words | 8 PagesThe cardiac cycle is the coordination of the filling and exhausting of blood by electrical signals that cause the heart muscles to contract and unwind. The contraction of the heart is directed by a nerve drive that goes from the SA node to AV node to AV group to Purkinje fibers to the myocardium. Amid the cardiac cycle, the heart contracts by means of systole, pushing blood out of the heart, and unwinds through diastole, filling the heart with blood. Cardiomyocytes, or cardiac cells, are striated and are in charge of the pumping of the heart; they are the main muscle cells with intercalated plates. The heart's inner pacemaker controls and times the thumping of the heart by means of electrical signals.

William Harvey's On The Motion On The Heart And Blood In Animals
713 Words | 3 PagesVesalius 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
Llamas Homeostasis
731 Words | 3 PagesLlamas maintain their homeostasis in similar ways as the rest of the mammals. Llamas have thick fur made up of coarse guard hair on the top layer, and short wavy fiber hair in the bottom layer. This prevents them from being cold in harsh weathers. Llamas have more red blood cells that most mammals so that they can adapt to higher altitudes. They also have bigger lungs which means more space and capacity in their lungs which gives them a bigger intake of breath.

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
