Have you ever thought about how the strongest muscle in your body is about the size of your fist.The heart is divided up into four chambers, two of these chambers are ventricles and the other two are called atria. Their is one ventricle and one atria on the left side of the heart and one of each on the right side of the heart as well. Each chamber is separated by a valve. On the left side the valves are called mitral valve, aortic valve. The valves on the right side of the heart are called tricuspid valve and the pulmonic valve. The middle portion of the heart is called myocardium. The outer layer is known as the epicardium. The front half of the heart includes the right atrium and the right ventricle. These two chambers are separated by the tricuspid valve and the pulmonic valve. The valves are important because they keep the blood flowing in the right direction. This portion of the heart is very essential because it takes blood from the walls of the heart that is low in oxygen and send it to the lungs so that it can be oxygenated. This is where the blood drops of the Carbon Dioxide and picks up oxygen. This is where the blood receives very important nutrients for the body. According to the world …show more content…
Just like the right side of the heart there are two valves that separate these chambers.The two valves are known as the mitral valve, aortic valve. The valves are an essential part of the heart because they ensure that the blood continues to flow in one direction. This is very important because if the blood flowed in any direction this would cause many problems. Unoxygenated blood and oxygenated blood would be mixed together. Which means that the rest of the body would not function properly because it would not have to right blood. The left side of the heart is key to successful body function because this half of the heart sends blood to your body through your
The normal Mitral Valve controls blood flow between the upper (left atrium) and lower chamber (left ventricle) of the left side of the heart. The mitral valve allows blood to flow from the left atrium into the left ventricle, but not flow the other way. With each heartbeat, the atria contract and push blood into the ventricles. The flaps of the mitral and tricuspid valves open to let blood through. Then, the ventricles contract to pump the blood out of the heart. The flaps of the mitral and tricuspid valves close and form a tight seal that prevents blood from flowing back into the atria (nhlbi.nih.gov).
This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.
of the heart: one chamber is on the top and one chamber is on the
Furthermore, Aristotle and Galen’s theories contributed to the Renaissance revival of heart anatomy. This reawakening made it possible for physicians to indicate the basic arrangement of the heart. It became commonly accepted that the heart was divided into four parts: two ventricles (lower chambers that pump blood out) and two auricles (upper chamber that r...
The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.
As learned in the class, mitral valve is between the left atrium and ventricle. At beginning of the systemic loop, oxygen-rich blood enters the left atrium and while the chamber fills up, the mitral valve is pressed to open and blood flows into the left ventricle. When the ventricle contracts, blood push the aortic valve and exits the ventricle. The left ventricle and atrium experience the similar cycle. The only difference is that instead of having the mitral valve, the valve between the right atrium and right ventricle is the tricuspid valve, which has three flaps while mitral valve only has two flaps.
The heart is one of the most unique organs in the human body. Its capabilities and functions truly are amazing. The heart 's function is to pump blood throughout the body supplying oxygen and nutrients to tissues. The heart is the size of your fist and weighs roughly 8-12 ounces depending if you’re male or female. The heart pumps through 100 kilometers of blood vessels for blood that is 3 to 4 times thicker than water at 60 to 80 times minute for a total volume of 5 million liters a year at rest. A basic diagram of the heart includes, right coronary, superior vena cava, aorta, pulmonary artery, pulmonary vein, right atrium, right ventricle, left atrium, left ventricle. There are more in
The pattern of blood flow starts in the left atrium to right atrium, then into the left ventricle and right ventricle. During its course, blood flows through the mitral and tricuspid valves. Simultaneously, the right atrium is granted blood from the veins through the superior and inferior vena cava. The job of the superior vena cava is to transport de-oxygenated blood to the right atrium. When your heart beats, the first beat represents the AV valves closing to prevent the backflow of blood into the atrium.
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...
It is about the size of a person's fist. The heart has four chambers. The upper two chambers are the right artium and left atrium, and the lower two are the right ventricle and left ventricle. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.
The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...
As humans we need the heart to pump blood all around the body in order
How to Use Squats to Get Muscular Legs By Jake Devenz May 30, 2009 For decades physical education teachers and coaches have used squats to work the lower body of their students and athletes. In fact, a squat will work the gluteus maximus, hamstring, and quadriceps at one time, while focusing on the abdomen, legs, and back. Squatting is considered to be an exercise that individuals can use to strengthen their body quickly and effectively. Some fitness experts feel that squats are not good for your knees and back, but there are others that feel if they are done properly, then they can be quite effective. When you are beginning your squatting routine, it is important that you do not begin with any weight for the first three weeks.
As an individual thinks about the heart they may not fully understand the amount of work that the heart does in order to keep the blood flowing throughout the body. The heart is made up of four chambers and two pumps. The top half of the heart is made up of a right and left atrium while the bottom portion of the heart is made up of a right and left ventricle. The right side of the heart pumps blood throughout the pulmonary circuit which supplies blood to the lungs. While the left side of the heart pumps blood through the systemic circuit which supplies blood to the tissues, muscles, and organs of the body.
The muscular system is a very important part of the human body. It has many components and functions, and is the source of the body’s movement. There are roughly 650 muscles in the human body and are different types of muscles. Muscles can either be voluntary or involuntary which means controlled or uncontrolled movement. Muscles have many reasons and in this paper you will widen your knowledge of muscles and their functions as well their diseases and how they help maintain the body.
