The Body's Circulatory System: The Cardiovascular System

Unit V- Cardiovascular system Subheading: 1. Cyanotic Congenital Heart Diseases 2. Acyanotic Congenital Heart Diseases 3. Acute Rheumatic Fever 4. Rheumatic Heart Disease 5.

The functions of the human cardiopulmonary system can be broken down into two, circulatory system and the respiratory system. The main goal of these two systems is to maintain homeostasis in our body. Homeostasis can be described as a type of condition where the internal continuity of an individual has to keep steadiness, regardless of any external changes from the outside environment. External changes from the outside environment may include factors such as excitement, stress, exercise, diet, and much more. Exercise can be carried out because the human body can endure a high level of exercise during a prolonged period of time.

Unit 5 Anatomy and Physiology for Health and Social Care P4 Explain the physiology of two named body systems in relation to energy metabolism in the body The two body systems selected in relation to energy metabolism in the body are the digestive system and cardiovascular system. The digestive system breaks down foods and the cardiovascular system enables absorption and usage of the food. The term energy metabolism in the body relates to chemical reactions that that maintain cells and organisms. It is divided into two categories: catabolism is the breakdown of molecules to obtain energy and anabolism the synthesis of all compounds needed by the cells.

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 cells include red blood cells, white blood cells and platelets. The red blood cells carry oxygen from the lungs and give blood its red color. The white blood cells fight infections. The platelets help form clots to stop bleeding in case of a cut.

Blood contains both slid and liquid form in our body and becomes a jelly like substance once it exits the body. A blood spatter deeply understands the proportion of blood and its various types. An analyst can describe how the blood came out of the body depending on the type of injury which took place. Blood can be looked like a flow, drip, spray, spurt or a gush (http://www.forensicsciencesimplified.org/blood/principles.html). Blood describes its velocity by its stains.

In addition, new red blood cells are produced by the bone marrow inside of our bones. You see, bones act as the "body 's warehouse" by storing or preserving calcium,

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.

In the case of the human circulatory system, approximately 55% of blood volume is composed of straw colored plasma while the remainder is occupied by the so called formed elements of blood: red blood cells, white blood cells, and platelets. Plasma itself is 90% water and contains many dissolved components: glucose, electrolytes (sodium, chloride, and bicarbonate ions); as well as a variety of proteins including albumin, clotting factors, and soluble antibodies. All of these plasma components contribute to the osmolality of blood, the most important ones being sodium and glucose. Physiologists have assigned a unit to blood osmolality called the

The components of blood include Plasma, Red blood cells, White blood cells (leukocytes), and Platelets. In Forensics

Heart is at the center of the circulatory system as it continuously pumps blood through various organs of the body, which in turn provides the much needed oxygen to keep them functioning well. The size of the heart is usually the same as the size as one’s fist. This mechanical organ has 4 chambers and is supplied by a complex array of blood vessels that bring blood to and from the heart. Heart failure is a term to describe the condition where the heart cannot do it’s work or does not manage its workload properly. Heart 's a muscle and heart failure leads to the weakening or deformation of that muscle, making it unable to supply enough blood.

For instance, blood serves as a replacement of blood lost during haemorrhage; platelets are used to stop postoperative bleeding; erythrocytes provide oxygen which is important for patients with severe anaemia. Through plasma transfusion, individuals with haemophilia get clotting factors while individuals at a risk of certain infections get immunoglobulins necessary passive immunity. Albumin from plasma may be used in treatments of traumatic shock or extensive burns (Armstrong,

The heart is one of the most important organs in the body, but unfortunately heart disease can weaken the cardiovascular system which could lead to fatal effects on this vital organ. The heart is the strongest organ in the body, pumping blood 70 times a minute (Avoiding Heart Attacks and Strokes), so if it becomes damaged, consequently the whole body becomes damaged (Allen 34). More than 60 million Americans suffer from some sort of cardiovascular disease (“Heart Disease”). Heart disease and heart attacks are cardiovascular problems because the effects it can leave on the heart and blood vessels are so horrific it can lead someone to their death, but fortunately there are many ways one can make changes in their life in order to avoid these

All of these organ systems need to help to make up the

Larger the ventricles, more is the internal work done to pump out blood by the muscle cells and more is the oxygen consumption. This leads to decrease in the mechanical efficiency of the heart. In various pathophysiological cases like Congestive Heart Failure, ventricular myopathies, ventricular hypertrophies etc. the efficiency of the heart decreases. And the progression of the disease is associated with the efficiency.
