1. Cardiovascular System is a complex network of the heart, blood vessels and blood. Its job is to deliver nutrients to the human body and remove excretory products from the body parts, it’s also protects the human body against infections, distribution of heat. At the centre of the cardiovascular system is the heart, a four chambered pump that dispenses blood to the arteries. The arteries carry nutrients and oxygenated blood to the body’s tissues.
The lymph vessels collect fluid, called lymph from the body tissues and return it to the blood, maintaining the fluid balance within the body. Lymph filters through the lymph nodes, which are packed with white blood cells known as lymphocytes. These are produced in the bone marrow, spleen and thymus, and they help to protect the body against infections. Spleen: This is the largest lymphatic organ. It is located on the left side of the body just above the kidney.
The blood from these arteries feeds the organs and systems (cells & tissues). Once the blood has given up all its oxygen it makes its way back through the heart, through the veins. Blood from the lower part of the body enters the heart through the inferior vena cava. Blood from the top of the body enters the heart through the superior vena cava. Blood only flows in one direction through the heart; the two values (bicuspid & tricuspid) ensure that this happens.
The abdominal aorta supplies the abdominal walls, viscera, and ends at T4 level where it branches into right and left common iliac arteries to supply the pelvis and lower limbs. The superior vena cava vein receives systemic blood draining from all areas superior to the diaphragm except the heart wall. It unites with the right and left brachiocephalic veins and empties into the right atrium. Both brachiocephalic veins are formed by the joining of the internal jugular and subclavian veins. The inferior
The blood supply to the brain is very important. Brain cells must have a continuous supply of oxygen and other nutrients from the blood in order to function. To meet this demand, blood is pumped continuously from the heart to the brain via several artery groups. Within the brain, these arteries (known as cerebral arteries) branch into smaller and smaller arteries, and eventually into tiny vessels called capillaries.
Hemorrhagic stroke (~17%)- A blood vessel breaks open, causing blood to leak into the brain 3. Define the term collateral blood flow, and describe how this and other factors affect the development of stroke. The brain has s circular vascular structure called the circle of Willis and two pairs of arteries that feed the circle. So most areas of the brain receive blood from more than one collateral blood vessel. The type, and severity of stroke symptoms depends on the location of the and severity of brain ischemia 4.
Right now I am located in the right femoral vein, which is located in the upper thigh and pelvic region of the body. It is also one of the largest veins in the venous system. The femoral vein’s purpose is to take all the blood in the lower region of the body and deliver it to the heart via the iliac vein. Today’s
Hypertension is High blood pressure, which is caused by the higher pressure of blood exerted on the artery walls Arteriosclerosis is a thickening, hardening, narrowing or loss of elasticity in arteries or blood vessels, which results in interference in the circulation of blood.

Diagnosis Difficulties Unit Fourteen Merit One In this essay I shall discuss the difficulties which can arise when the diagnosis of stroke and diabetes is undertaken and how the signs and symptoms to which they could be showing can help to diagnose their illnesses more effectively and efficiently. There are various signs and symptoms to which individuals experiencing strokes would demonstrate, however they may vary from person to person which is one of the reasons to which a difficulty to the noticing the stroke may arise. One of the most common signs is that the stoke will happen and begin suddenly and as the stroke develops it will affect different parts of your brain that control different parts of your body and therefore the symptoms
