glomerulus and into the efferent arteriole. The varying sizes of these arterioles help to create the hydrostatic pressure and to maintain consistency of glomerular capillary pressure and renal blood flow within the glomerulus Before returning to the renal vein, blood from the efferent arteriole enters the peritubular capillaries and the vasa recta and flows slowly through the cortex and medulla of the kidney close to the tubules. peritubular capillaries - surround the proximal and distal…

sometimes be puzzling. These are two diverse conditions. One kind of prolapse discussed below can be a result of long-lasting hemorrhoids. In rectal prolapse, the portion of the rectal wall projects via the anus. In hemorrhoids, it is the swollen veins that may project through the anus. It may also develop below the skin around the anus. Straining to pass stool over a lengthy period of time can upsurge the jeopardy of hemorrhoids and rectal…

her poem “In a Lighter Vein” to explore the idealization of women by men. Sor Juana creates these binaries in order to critique this idealization and presents them in a dichotomous nature to clearly illustrate the indecisive and misguided needs of men. Sor Juana’s use of binary language aligns with French feminist theorist, Ann Rosalind’s categorization of binary language to be more of a masculine discourse, and thus could be argued that Sor Juana writes “In a Lighter Vein” in such a discourse.…

fluid loss occur in many different ways, however because the most common cause is of severe blood loss, it is best to first discuss types of hemorrhage and the care that follows. Severe hemorrhage is most often caused by a tear in a major artery or vein that are located deep below skin and muscle tissue (Red Cross 160). A tear can be result of an external wound or from damage to internal structures, both display different symptoms and require different…

Breathing air in and out is the first step to the respiration process. Respiration is a series of metabolic reactions and processes that take place within the cells of organisms. The organisms store biochemical energy within adenosine triphosphate (ATP) molecules. For the process to being, we must first draw air into our lungs. The lungs muscles contract and expand the chest cavity, causing a negative or hypotonic pressure within the pleural cavity. The hypotonic pressure then forces the lungs…

1 Cardiopulmonary bypass (CPB) 1.1 Introduction Cardiovascular diseases are the leading cause of death globally. Different types of cardiac operations are performed every day in hospitals varying in complexity to treat several lesions such as coronary artery bypass graft, heart valve replacement and total heart replacement. Cardiopulmonary bypass (CPB) is a crucial technique employed in the majority of these operations (Punjabi and Taylor 2013). It takes over the function of the heart and…

Spider veins are small blood vessels that are close to the surface of your skin. They often appear as red or purple threads on the nose, cheeks, chin and chest and are most often caused by the natural process of aging. However, they may also be caused by exposure to the ultraviolet rays of the sun, trauma to the skin such as an injury and by genetics. Spider veins on the face are unsightly and many people use makeup to cover them, but they can be removed with laser treatments. Lasers are…

The conventional on pump CABG employed CPB to extracorporeal oxygenate the venous blood through the machine and then pump the blood back to the patient while the surgeon perform anastomosis between a graft and a coronary artery. During the surgical procedure, a cross-clamping was applied on the aortic artery to provide myocardial protection, and the heart was induced to cardioplegia with drugs, so the surgeon can perform anastomosis on a motionless field, thus guaranteeing the quality of the…

days greatly increase the risk of suffering from a very serious medical condition referred to as Deep Vein Thrombosis. Doctors are fearful that the increased number of professionals working in an office setting will lead to an increase in cases of a specific type of blood clot called Deep Vein Thrombosis. What Deep Vein Thrombosis refers to is simply the formation of a blood clot in the deep vein of the legs. When these blood clots grow they can break off and find their way to the lungs where…

(with their contained fluid, blood). The heart is a muscular organ and pumps blood to all parts of the human body by the process of contraction. Pure-.oxygenated blood is carried by the dhamani (arteries) and impure-deoxygenated blood by the sira (veins). Some common cardiac ailments and there Ayurvedic management is discussed below High blood pressure (Hypertension) Cause: Age factor is the leading cause of hypertension. With passage of time the elasticity of the blood vessels particularly…
