Introduction The primary function of the heart is to transport blood throughout the body‚ which delivers oxygen‚ nutrients and chemicals to the cells of the body to ensure their survival and proper function and to remove the cellular wastes. For the body to achieve this‚ it must maintain a certain blood pressure within the body to overcome gravity and orthostatic changes. If the body did not keep a certain pressure‚ distal cells and organs would not be able to receive a constant blood supply and

When the heart is no longer able to pump enough blood to meet the demands of the body‚ it is referred to as heart failure or cardiac insufficiency. Congestive heart failure (CHF) is an abnormal condition characterized by circulatory congestion as a result of the heart’s inability to act as effective pump. Circulatory congestion and compensatory mechanisms occur. CHF may develop after MI‚ in response to prolonged hypertension‚ diabetes mellitus or in relation to valvular heart disease or inflammatory

Anatomy and Physiology 1. Bone – Bones are made up of different types of tissues and join together to form the skeleton of the body. Their primary purpose is to provide structure for the body and to protect organs. It also serves as a storage site for minerals as well as producing and storing blood cells. The three different tissues that bones are composed of are: a. Compact Tissue – The dense outer tissue in a bone. b. Cancellous Tissue – The sponge like tissue inside the

side of head‚ Right side of neck‚ Right Thoracic cavity In a typical capillary bed‚ the balance of hydrostatic and colloid osmotic pressures results in FILTRATION occurring at the arterial end of the capillaries and REABSORPTION occurring at the venous end. Overall‚ FILTRATION from the plasma normally exceeds REABSORPTION resulting in the net formation of tissue fluid. Lymph drainage is important for the – absorption of dietary fats‚ return of small proteins from tissue fluid to blood‚ transport
