The heart forces the ‘oxygenated’ blood through a range of connecting blood vessels specifically speaking arteries which travel around your body providing your cells with the necessary materials that the blood contains. As the blood reaches your cells the oxygen is released in order for the cells to function. The cells then give out waste materials which can include co2 and water. In order for your blood to receive these waste products they absorb it.
The loose blood clots can block the artery in the heart and become pulmonary embolism (PE). A pulmonary embolism is dangerous conditions that can lead to fatal because of blood supplies from the heart to the other parts of the body are failed. DISEASE CLASSIFICATION Deep vein thrombosis can be classified to three categories which is idiopathic, acute and chronic.
These small veins are called venules. Venules collect blood from capillaries and drain into veins. 5 - Veins are the blood vessels that carry blood back to the heart. They may contain valves which stop blood flowing away from the heart. Describe the 3 main types of blood circulation? - https://www.reference.com/science/three-types-circulation-28f4fb9363b09f33
Then blood moves down into the left ventricle. It is then pumped into the ascending aorta. From the aorta, the oxygen-rich blood is sent to the brain, to the heart muscle, and to the lower body. Blood returning to the heart from the fetal body contains carbon dioxide and waste products as it enters the right atrium. It flows down into the right ventricle.
Failure in one organ can cause other organs in the body to come under stress and restrict body functions. In the long run organ failures can endanger a patient’s life. Multiple organ failure occurs when two or more organs in the body fail. There are many reasons for organ failure and each organ has its own reasons as related to its function. Some common reasons for organ failure
Usually when somebody has a heart attack, people sometimes wait a while before seeking the much needed medical attention. It is extremely important that the patients gets medical treatment as soon as possible after the occurrence of the myocardial infarction as this increases the chances of their survival. CAUSES Myocardial infarction is usually caused by a blockade in the blood supply of the heart muscles. This can occur when there is the hardening of the arterial walls, or if there is an thrombus or embolism in the blood vessels and this reduces the amount of blood that can go through. If there is a complete block, then this can cause the area where the blood vessel supplies the blood to undergo necrosis which is also known as heart attack.
(ii) The septum- this divides the right and left sides of the heart. (iii) Pacemaker- this sends out regular nervous impulses which travel along the axons of the pf the nerve cells out through the walls of the atria. It is located at the top right of the atrium.
Blood provides the body with oxygen and nutrients and also assists in the removal of waste. The heart is a pump that drives the whole circulatory system. It receives and propels blood, rhythmically contracting, forcing the blood through a system of vessels. The hearts action is controlled by the autonomic nervous system. STRUTURE OF THE VEINS, CAPILLARIES AND
Lymph flow through the node is one-way, entering through several afferent vessels on the convex side of the node’s ‘bean shape’ which contain valves opening toward the node’s centre, directing lymph into the node. Lymph then flows through three sinuses, irregular channels containing branching reticular fibres, lymphocytes, and macrophages, first the subcapsular sinus, immediately beneath the capsule, then the trabecular sinuses extending through the cortex parallel to the trabeculae, and then into the medullary sinuses. All sinuses filter the
This concept is taken from Block 4, Module 7 which is entitled as ‘Assessment of cardiovascular system’. The cardiovascular system can also be referred to as the circulatory system. It comprises of the heart and the blood vessels. The major function of the cardiovascular system is to transport nutrients and oxygen to all parts of the body and to remove waste products from the body like carbondioxide.
Bile is handled improperly and thus begins to circulate in the bloodstream, causing the skin color to change to yellow. • Cirrhosis: A progressive chronic inflammation of the liver that typically results from severe chronic hepatitis or chronic alcoholism. • Ascites: Abnormal accumulation of fluid within the peritoneal cavity; is excessive, causes visible
•Then travels to the bachmann’s bundle and the internodal pathways... •The internodal pathways then join together at the atrioventricular node... •As the bundle of his goes down the septum (the wall that divides the two sides of the heart) • it splits into the left and right bundle branch... •Which then produces the terminal purkinje fibres which travel up to the left and right ventricles (lower chamber of the heart) Structure of the heart
Takayasu Arteritis Takayasu arteritis is a rare condition that may also be called pulseless disease. Takayasu arteritis is caused by inflammation in your large blood vessels (vasculitis). It mainly affects your aorta, which is a large blood vessel that carries blood away from the heart, and the large blood vessels that branch off from it. Areas of the aorta or other affected blood vessels can become narrowed, blocked, or weakened because of the inflammation.
So what exactly is rhabdomyolysis? It is an imbalance in the muscle that happens when the muscle tissue of an affected area breaks down quickly, which can release its toxins into your blood stream. This can be caused by a hard hit to a muscle, causing muscle injury, as well as from the use of certain narcotics and even severe dehydration (Cervellin 2010). As learned in the course muscles are composed of sarcolemma which is the membrane that is composed of many Na+, K+ and Na+, CA+ channels that when a muscle is injured , stop functioning
Elliott Cole Mr. Jason Long, Instructor EMS Academy 20 January 2016 Anaphylactic Shock Anaphylactic shock and Anaphylaxis are serious medical conditions that are a result of insufficient blood flow throughout the body. Anaphylactic shock refers to severe hypersensitivity or an allergic reaction. Causes of Anaphylaxis often include allergic reaction to foods, medications, or insect stings. Anaphylactic shock on the other hand, is a medical emergency which can lead to other conditions such as a lack of oxygen in the body 's tissues (hypoxia), heart attack, cardiac arrest and even severe organ damage.
