Essays on Venous Blood

The case of James a 48 year old male is a case of a patient with DVT but with little information. This man is a lawn tennis player with some issues that made him visit the emergency room and had the boot placed on him for 4 weeks duration. It was after that episode of medical management that he noticed a form of ankle to calf swelling on one of the legs. The swelling was really abnormal in terms of size hence he needs to see the doctor urgently. Despite swelling and the test such as ultrasound done, the extent of severity to him ...

VENOUS STASIS ULCER

Venous stasis ulcers commonly occur in the legs due to venous insufficiency or poor venous blood drainage. Veins of the legs have valves in then which ensures a proper unidirectional flow of blood towards heart. In venous stasis, these valves are damaged, thus the venous blood accumulates in the legs instead of being pumped upwards. A prolonged pooling of blood in the leg leads to increased pressure in the affected area thus causing a break in the skin and causing ulcers. The causes for venous stasis could be smoking, occupations requiring prolonged hours of standing, obesity or deep vein thrombosis.

Introduction

According to Huether (2012), venous insufficiency is a medical condition characterized by the inability of the veins of the lower extremities to effectively push blood back to the inferior vena cava. The venous blood evades its normal antegrade flow path and refluxes down the veins in the lower segments resulting to lower limb venous congestion. Syndromes in this condition are mostly due to valvular incompetence common in the low pressure superficial venous system, although they may also be due to incompetence of the valves in the deep venous systems.

Pathophysiology of CVI

The failure of the valves of superficial veins is attributed to ...

Introduction:

Carbon dioxide is generated through cell metabolism that takes place in the mitochondria. Carbon dioxide amount that is produced is dependent on the metabolism rate as well as on the relative carbohydrate, protein and fat amount being metabolized. The amount of carbon dioxide produced at rest is usually about 200 ml per minute eating a mixed diet (Arthurs &Sudhakar 2005). Carbon dioxide is one of the main products that are released following metabolism and the level of it in the body is highly regulated. This paper aims at discussing the production and transport of carbon dioxide from the cells through ...

Introduction:

Carbon dioxide is generated through cell metabolism that takes place in the mitochondria. Carbon dioxide amount that is produced is dependent on the metabolism rate as well as on the relative carbohydrate, protein and fat amount being metabolized. The amount of carbon dioxide produced at rest is usually about 200 ml per minute eating a mixed diet. This results in the utilization of about 80% of oxygen and gives respiratory quotient of 0.8 (Arthurs & Sudhakar 2005, p. 207). Carbon is one of the main products that are released following metabolism and the level of it in the body is highly ...

A condition affecting the system of veins in legs with venous hypertension resulting in different pathologies that involve swelling, ulcerations, pain, skin changes, and edema is called chronic venous insufficiency (Eberhardt and Raffetto, 2005). It is necessary to understand normal venous function and anatomy to analyze the venous insufficiencies pathology. The peripheral venous system serves as a conduit returns blood into the heart and as a reservoir where blood is stored. Appropriate operation of the peripheral venous system is dependent on a series of muscle pumps and valves (Eberhardt and Raffetto, 2005). Blood entering the venous system of lower extremities has ...

1.0 introduction Thermoregulation is basically temperature regulation. It is a homeostatic process where by the internal temperature of an organism is kept constant within a specific range despite fluctuations in the external temperatures. It is important to note that all homeostatic systems use negative feedback mechanism. This implies that whenever there is a change in external or surrounding temperature of an organism, consequently a corrective mechanism is initiated within or without the organism to counter the change. Not all animals can maintain a constant body temperature; this is possible only for birds and mammals. Such animals are referred to as endotherms or commonly ...
