2.02 Circulatory: What are the functions of blood? Transportation: Carries oxygen to tissues‚ Carbon Dioxide from tissues‚ nutrients and waste products. Regulation: circulates excess heat to body surfaces and lungs. PH is regulated through buffers and amino acids that it carries. Protection: Circulates antibodies and defensive cells to combat infection and disease‚ also produces clots to prevent excessive loss of blood. Functions of blood components Plasma: Makes up about 55% of blood volume. Plasma

The term shock is used to describe a clinical syndrome which is characterized by severe circulatory failure leading to impaired tissue perfusion‚ impaired cellular respiration and metabolism‚ consistent development of organ dysfunction‚ organ failure and death. The shock is always a life-threatening condition‚ which is why the diagnosis‚ evaluation and treatment of patients with circulatory shock should be implemented simultaneously. There are three degrees of shock: 1 Stage I (also called compensated

a) As the veins are responsible for returning deoxygenated blood to the heart‚ they are most often working against gravity. The blood is prevented from reversing direction through large venous valves. However‚ if the pressure applied downwards on these valves is great enough and applied for a significant period of time‚ such in the case of prolonged periods of standing‚ the edges of the veins can become distended and eventually prevent the edges of the valves from successfully sealing. Varicosities

CIRRHOSIS Cirrhosis of the liver refers to the scarring of liver due to poor liver function and development of various liver diseases caused by conditions such as alcohol abuse‚ buildup of fats in the liver‚ and hepatitis. In most of the cases‚ liver is able to regenerate the new liver cells when they are damaged. However‚ if the damage has occurred for a longer period of time and becomes severe‚ regeneration of the cells would be incomplete. This‚ in turn‚ leads to the formation of the scar tissues

Lab Report 3: Daphnia‚ Human and Crayfish Cardiac Activity Introduction An electrocardiogram‚ abbreviated as ECG in this report‚ is a visual representation of an organism’s atrial and ventricular depolarization and repolarization. Previous research has shown that although there is variability in the amplitude and shape of the waves of ECG‚ dependent on the subject’s health‚ it follows a universal pattern that can be used effectively for biometrics. The experiments discussed in this lab report were

BPPV is a mechanical disorder which occurs as a result of the displacement of tiny crystals of calcium carbonate‚ also called otoconia. Typically‚ otoconia reside in the otolith organs and play a crucial role in detecting head movement. When the crystals get displaced‚ often due to trauma‚ they collect in one of the semicircular canals and cause vertigo symptoms. When the head is still‚ the otoconia settle within the semicircular canals and there are no vertigo symptoms. When the head is rapidly

The Sanskirt Proverb states‚ “for breath is life‚ and if you breathe well you will live long on earth” This could not be more true. Without oxygen‚ life itself would be nonexistent. Imagine what would happen if wounds did not get better‚ incisions did not heal‚ and burns did not improve. This is where hyperbaric oxygen therapy (HBOT) comes into play. Oxygen is necessary for the replenishment of tissues‚ healing of the body and assisting with general ailments. HBOT is used for a wide variety of treatments

Cellular Respiration is part of the metabolism of organisms‚ it provides the energy for organisms’ basic life activity. The process of cellular respiration converts oxygen and water to glucose and carbon dioxide‚ and usually occurs inside of mitochondria. Thus the cellular respiration is closely related to the life of all organisms‚ especially the human. In a case study in cellular respiration‚ seven unrelated people died in five days‚ and the reason is unclear. However‚ all the victim had same

Tunneled Catheter Insertion Tunneled catheter insertion is a procedure to insert a thin‚ flexible tube (catheter) into a vein. The catheter makes it easier to draw blood‚ give blood products‚ remove waste products from the blood (hemodialysis)‚ and give medicines. This procedure is usually done when the bloodstream needs to be accessed many times over a long period of time. Tunneled catheters can be placed in different parts of the body depending on how they will be used. The most common place
