Cardiovascular disease - Wikipedia Cardiovascular disease - Wikipedia
Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels. Cardiovascular disease includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack).

Exogenous plasminogen activators are used to dissolve clots in the coronary arteries. Evidence for protection by breast-feeding against infant deaths from infectious diseases in brazil. On the contrary, a patient with polycythaemia and a pcv of 60 has a high oxygen transport capacity, but the blood viscosity is dangerously high and he may develop thrombosis and emboli (fig.

When blood is saturated under the normal ambient oxygen partial pressure (20 kpa or 150 mmhg), the oxygen capacity of haemoglobin is 1. This pressure is much larger than the interstitial colloid osmotic pressure, so that the colloid osmotic gradient across the capillary wall is a net inward force, which draws water into the capillaries. In resting skeletal muscle capillaries, the pressure is 4.

The heart normally has a self-firing unit, located in the right atrium, called the ), elongated intermediary cells and ordinary atrial cells. Wilson rm, runciman wb, gibberd rw, harrison bt, newby l, hamilton jd. Heparin is a negatively charged mucopolysaccharide from mast cells.

It is uncertain whether capillaries may be able to alter their shape according to the needs of the tissues. Vitamin c or ascorbic acid cannot be synthesised in humans, but the vitamin is present in all fresh fruit and vegetables. When valvular diseases cause the valves to open too little ( states that the total driving energy, applied to a continuously flowing, small, ideal fluid volume (d ), which is flowing frictionless and laminar, equals the sum of 3 types of energy the kinetic energy (12 ) multiplied by the squared velocity) , the potential energy at the height (h) and the gravity (g), and the laterally directed energy (ie, the lateral pressure, the lateral pressure is highest, where the velocity is lowest (eg, aneurysm ruptures).

Newtonian fluids move streamline or with so-called ideal laminar flow. It is low in the lungs and intestine (1 kpa) and particularly high in the renal glomerular capillaries (6-8 kpa). The law of conservation of matter states that mass or energy can neither be created nor destroyed (the principle of mass balance).

Smoking, smoking cessation, and lung cancer in the uk since 1950 combination of national statistics with two case-control studies. Respiratory health effects of passive smoking lung cancer and other disorders. Failure of bile excretion leads to accumulation of bilirubin in the body. Stem cells maintain normal cell populations in a healthy bone marrow controlled by haemopoietic growth factors, and stem cells have the capacity for self-renewal. Here, they lose their rna after a couple of days and become mature red cells.

Chapter 1 Cardiovascular Disorders Case Study 8 The stem cells are stimulated to produce proerythroblasts, which speed up the production of new red cells after a few days. The conducting system consists of modified myocardial cells. Haemoglobin a comprises almost all haemoglobin in adults, supplied with only a minimum of haemoglobin a the polypeptide chains are not covalently linked but are held together by hydrophobic forces, During the systolic period 26 ml of blood 38) is streaming through the resistance vessels, leaving the arterial system, so the systolic is 44 ml of blood. The number of is not high enough to balance the decrease in vessel diameter. Haemolytic anaemia is characterised by osmotic fragility, reticulocytosis, increased serum-bilirubin, and erythroid hyperplasia of the bone marrow. Intrinsic factor is a glycoprotein, which combines with vitamin b available for absorption in the ileum. He is depressed and suffers from frequent coughs.

    Tight junctions with narrow clefts are difficult to pass for the dissolved molecules and ions. Theoretically, oedemas are caused by a colloid-osmotic pressure gradient, which is too low and caused by too low concentrations of plasma proteins (so-called with too much protein in the oedema fluid). A rise in 2,3-dpg improves the release of oxygen to the cells. Since the concentration of haemoglobin in a normal red cell is maximal, the maximal value (380 gl) is the highest occurring. Aneurysms are found as pulsatile dilatations of the abdominal or thoracic aorta (ct scanning or ultrasound examination).

    In resting skeletal muscle capillaries, the pressure is 4. The av node consists of the same cell types as the sinus node. The incision is blotted with filter paper at 30 s intervals. Each day has 1440 min, so the plasma flow is (714400. The disorder is tests the capacity of platelets to form plugs.

    Typically, the average diastolic pressure will rise with age. Mchc is calculated from the haemoglobin concentration by division with the packed cell volume (pcv). Laplace equation can be developed from the equation above (fig. The formed fibrin monomers polymerise into insoluble strands of fibrin polymers (fig. The quantification of mortality resulting from the regular use of illicit opiates. The mcv index is used to classify anaemias into microcytic (mcv96 fl), but the classification is not causal. The left and right ventricles provide most of the energy needed to transport the blood through the circulation. Blood cells consist of red cells (erythrocytes) and white cells (leukocytes). The anatomy of the four heart chambers is shown to the right. A patient with anaemia and a pcv of 30 has a low blood viscosity and a poor oxygen transport capacity ( ).

    The microcirculation is responsible for the transport of nutrients and oxygen to the tissues, and for removal of cellular waste products and co. The time is also prolonged in haemophilia and in other disorders with defective intrinsic pathway factors. Perhaps the stretch of smooth muscle cells opens ca macromolecules do penetrate the capillary wall and the content of lymph derives from plasma. These are formed by two adjacent cell membranes that have fused during removal of the lipid bilayers, so only a diaphragm of protein lattice is left allowing bulk flow without colloids ( ). Even a cardiac transplant patient (the heart is totally denervated) adapts to the altered needs for cardiac function and of course initiates new heart beats as long as the transplant is functioning Buy now Chapter 1 Cardiovascular Disorders Case Study 8

Sacramento california environmental protection agency (calepa), office of environmental health hazard assessment 1997. The principal function of the bloodflow in the cardiovascular system is to provide oxygen ) and nutrients to the tissues of the body and to remove carbon dioxide (co ) and waste products.

    The reduced viscosity can reduce the total peripheral vascular resistance (tpvr) to less than half of the resting value, which is an appropriate event, since it easens the cardiac work and improves the bloodflow. The myocardial anoxia results in cardiac failure (fig. The enzymes are all endopeptidases (proteases), and their catalytic sites include a serine moiety. The equation of continuity states that the velocity varies inversely with the cross-sectional area of the tube. Negatively charged surfaces on damaged cells generate thrombin, trigger inflammatory and immune responses and even activate fibrinolysis.

    Platelets provide substances that enhance thrombin production, such as phospholipid, the important cofactor in the clotting process. An optimal timing of atrial and ventricular pumping allows the emptying of the atria to be completed before the ventricular contraction. This amount of protein leaves the blood in the capillaries, and returns almost completely to the blood through the lymph and not the veins (fig. A patient with anaemia and a pcv of 30 has a low blood viscosity and a poor oxygen transport capacity ( ). Hence, (small molecules of nourishment and waste products) through the capillary wall.

    In the pulmonary system, blood is pumped from the right ventricle through the lung capillaries and is temporary collected in the left atrium ( ). Hepatocytes produce factors x, ix, vii, and ii only when vitamin k is present. The low oxygen capacity of haemoglobin is compensated by an increased coronary bloodflow at rest. Finally the monomers of the fibrin strands are cross-linked by the enzyme activated (a) fibrin-stabilising factor (xiiia). Its parent molecule is prothrombin (factor ii), which is present in normal plasma.
