Capillary

from 20,000 to 500,000 per cubic millimeter of blood. Platelets are useful to the body because they contain and release the substance called thromboplastin, a type of protein needed for blood clotting. Platelets also help to plug leaks in broken capillary walls. Nerve cell Nerve cell or neuron receive stimuli and transmit action potentials to other neurons or to effectors organ. They transmit nerve impulses from place to place in the body. They initiate and conduct electrical discharges.…

way to dad’s other lung, his pulmonary arteries to be precise. That caused him to have shortness of breath. Although that is not the worst part of it. The worst part is that the scar tissue was literally squeezing his pulmonary arteries until the capillaries…

Physiological Effects of Decreased Atmospheric Pressure At lower altitudes such as sea level, the main stimulation for ventilation is carbon dioxide. (7) At high altitudes, hypoxia stimulates ventilation. (7) However, hypoxia only stimulates ventilation when the partial pressure of inspired oxygen is reduced to roughly 13.3kPa, and is at an altitude of 3000m or more. (7) When the inspired partial pressure of oxygen is 13.3kPa, alveolar oxygen pressure is 8kPa. (7) As hypoxia continues to…

The ABCDE framework (Resuscitation Council 2005) is an acronym that is used for assessment and treatment for critically ill patients. It is a framework that is widely recognised and when used correctly can form the basis for a rapid, yet systematic and therefore thorough initial assessment (Jevon 2010; Page and McKinney 2012). It also assists in determining the seriousness of the condition and helps to prioritise the interventions needed (Page and McKinney 2012; Thim et al. 2012). It is…

from thick-walled muscular vessels to saclike flaccid vessels. Placental hypo-perfusion, caused by the incomplete invasion leads to the release of systemic vasoactive compounds that results in an exaggerated inflammatory response, vasoconstriction, capillary leak, hypercoagulability, platelet dysfunction and endothelial damage (Lim, 2016), all which directly correlates to the severity of maternal hypertension. Another possible cause of preeclampsia is due to an imbalance between prostacyclin and…

Introduction The human cell consists of three parts; the plasma membrane, the cytoplasm, and the nucleus. The plasma membrane is the outer boundary of the cell, it separates two major fluid compartments- the intracellular fluid and the extracellular fluid, and plays a key role in cell transport. Cell transport is the movement of materials across a selectively permeable membrane, and this process can occur in two ways; passive transport and active transport. Passive transport allows substances to…

The coronary veins are responsible for collecting the oxygen-depleted blood which is a result of the exchanging of oxygen-rich blood within the capillary beds of the myocardium. The three major coronary arteries associated with coronary circulation are the small cardiac vein, the middle cardiac vein, and the great cardiac vein. These three coronary veins ultimately join to form the coronary sinus…

Vascular anomalies are a serious medical condition that affect blood vessel formation in as many as 1 in 10 people (Richter and Suen 2015). Vascular anomalies can be divided into two broad categories: vascular tumors and vascular malformations (Richter and Suen 2015). Vascular tumors, also known as hemangiomas, are characterized by rapid growth with most undergoing involution once the patient has reached a certain age (Richter and Suen 2015). On the other hand, vascular malformations are…

Glomerulonephritis Mitchelle Hamilton Millers College of Nursing BSN 6 November 5th, 2015 Abstract Glomerulonephritis (GN) is a type of kidney disease that involves the glomeruli. These are very small, important structures in the kidneys that supply blood flow to the small units in the kidneys that filter urine called the nephrons. During glomerulonephritis, the glomeruli become inflamed and impair the kidney's ability to filter urine. This can be a routine condition in childhood.…
