Dear Human Body Corporation: Circulatory System

The cardiovascular system is the process of the heart pumping the blood around the body through blood vessels, arteries, veins and capillaries. The main functions of the system are to transport materials to and from the cells around the body, to assist in temperature, to keep the levels of fluid in the body at the correct level, to distribute heat around the body and to defend the body. This system is the heart, which is a muscle that pumps blood around the body through arteries, veins and capillaries. Blood transports oxygen to the body cells which helps them to metabolise energy in the body. During this process the blood is also getting rid of any waste products of respiration, carbon dioxide and water. Blood also helps to supply heat, hormones, nutrients, salts and urea around the body. The heart is placed in between the lungs which is protected by the rib cage and is the size of a fist.

The system works because in blood there are antigens and agglutinogens. In type A, only type A antigens on the red blood cells. Similar to this type B only has type B antigens. Type AB has both A and B antigens, which is why it is the universal recipient. Type O has neither A or B antigens making it the universal donor.

Chapter twenty is the last one of the circulatory system and it discussed about the blood vessels and circulation. Blood vessels is the distribution network or the network of tubes. There are three main blood vessels in the heart there are artery, veins and lymphatic. The arteries are all the blood vessels that take blood out from the heart. It tends to be thick, strong and tough because all the blood is rushing through the arteries. The arterioles are like the mini arteries that branch off of the arteries. Capillaries are the smallest blood vessels that comes off from the arteries and physically takes blood, oxygen and nutrients inside the blood to the cells that need it. It connects the arteries and vein and the it main function is to exchange

The second body framework is the cardiovascular system which contains the blood, heart, and vessels. The cardiovascular system heart pumps blood through veins, blood conveys oxygen and supplements to cells and carbon dioxide and waste far from cells. It manages body temperatures and water substance of body fluids and blood. This system contains of the heart, veins, and arteries. The heart is somewhat little and lays on the diaphragm which rests on the mediastinum and is located in the thoracic cavity. The mediastinum reaches out from the sternum to the vertebral column. From the first rib to the diaphragm and sits between the lungs. The heart has an apex which is the pointed end of a cone shaped structure, and a base which is the posterior

Circulatory overload: occur when the IV roller clamp is loosened and the infusate is allowed to run into the vein quickly. The patient may be anxious, experience respiratory distress, crackles in the lung bases, increased blood pressure and neck engorgement. Treatment includes raising the head of the bed, administering oxygen and IV furosimide as ordered, and prompt notification of the physician

The circulatory system, also called the cardiovascular system, distributes vital nutrients throughout the body. The main organs are the heart and the blood vessels that run throughout the entire human body. Blood runs through the entire body, in the blood vessels, and contains cells and plasma.

The cardiovascular system, the workhorse of the body, has long been an object of fascination by civilizations. How does such a tiny muscle support the life of a human for such a long period of time? The answer lies within the physiology of the cardiovascular system itself. Simple one-celled organisms had one major problem when it came to the diffusion of oxygen, the oxygen required by a mammal for instance, would be much greater than the rate at which these cells could diffuse oxygen. Thus the need for a more efficient process was integral in the creation of cardiovascular system as we know it today. The ability of the heart to pump blood fast enough (and in continuous loops) allows for this absorption of vital nutrients in a prompt manner. However the common knowledge we have currently about the way this system works is a relatively new understanding. In the 17th century, an Italian anatomist named Marcello Malpighi observed the capillary exchange between interstitial fluid and blood. This idea was a radical one (p.463-464). Common belief at the time was that the cardiovascular system distributed both blood and air. Many had thought that blood was produced in the liver and was distributed through the veins and also believed that it was the arteries that distributed oxygen to the body. William Harvey disproved this belief when he discovered that that weight of blood pumped by the heart in one hour exceeds the weight of the entire body. He soon discovered the one-way loop in

Unit D: Human Systems in Biology 20 is one of the main sections that becomes relatable to the Program of Studies (POS) for the Heart Rate and Exercise LabQuest activity. General Outcome #2 focuses on how students will explain the role of the circulatory systems and defense systems in maintaining an internal equilibrium. This further goes into measuring the students level of understanding the concepts of heart rate and the factors that affect it (Alberta Education, p. 41). Heart rate can then branch out into concepts of maximum heart rate, resting heart rate and recovery time. Through the LabQuest experiment, the main affecting factor was exercise and how that relates back to the fitness level of an individual [20-D2.3s]. Other key concepts found in the lab’s analysis questions then dealt with disorders of the heart [20–D2. 2sts]. Students are additionally "conducting investigations into relationships between and among observable variables" through the use of tools to gather information in regards to their heart rates [20–D2.2s]. Through group work activities, they are achieving collaborative work in measuring heart rate and other factors relating to the circulatory system [20-D2.4s]. To analyze and interpret, the POS explicitly states that students have the option in determining, from available data, the relationship between blood pressure and exercise [20–D2.3s a]. For the simulation, predominantly at the high school level, the

The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.

Explain the relationship between the structure and function of the following parts of the circulatory system?

The capacity of the circulatory framework is that it moves supplements to the cells, and offers the blood some assistance with flowing through our body. The heart is pumping so as to control the supplements and the warmth the blood to the veins, to pass every one of the supplements to the cells.The motivation behind this test is to figure out what happens to individuals circulatory framework in the event that they go into cool water. What's more, what will be doing keeping in mind the end goal to figure out what happens, we need to make a man put his/or her face in water with ice 3D squares for 25 seconds-30 seconds to see what happened with his/or her circulatory framework.

The human body needs oxygen to sustain itself. The human respiratory system is a group of organs that take in oxygen and let out carbon dioxide. The main organ of the respiratory system is the lungs. Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed.
