The Digestive Track The BIG MAC is placed in the mouth. The bread is mainly starch‚ the special sauce is mainly fat‚ lettuce‚ pickles‚ and onions are niacin. The beef patties are protein‚and cheeseis a form of calcium‚ fat‚ and protein. The piece of the BIG MAC is placed in the mouth and chewed‚ the starch is being digested by saliva. The starch becomes a kind of sugar which is used as a nourishment for the cells. Saliva changes food to a form that can be used by the body called enzymes.

The cardiovascular system is a closed organ system that is found within humans and other vertebrates. The heart consists of the right and left ventricle‚ right and left atrium‚ aorta‚ capillaries‚ pulmonary arteries and veins and the anterior and posterior vena cava. All of the following structures maintain the heart’s beating cycle and the circulation of blood throughout the body. Three main types of blood vessels: Arteries - Thick-walled tubes in which blood is brought from the heart to various

The body system that most interests me is the cardiovascular system‚ I chose this system because I’m fascinated with how the heart works and how the blood flows throughout our whole body. The heart is a muscle that contracts which allows blood to be pushed throughout the body. The heart provides many nutrients and blood to the whole body along with many vital organs. The heart is spilt into four chambers: the right atrium‚ left atrium‚ left ventricle‚ and right ventricle. The blood flow starts in

TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. The term anatomy refers to the structure and relationship of body parts such as tissues and organs. Physiology on the other hand is how these structures work as in individual and in the body as a whole. Take the circulatory system for example. The heart itself‚ blood vessels and blood is the anatomy. How these

The digestive tract is a continuous tract throughout the body that interfaces with the environment at both its origin ‚the oral cavities‚ as well as‚ at its termination‚ the anus. It is divided into different segments beginning with the oral cavity and followed by the pharynx‚ esophagus‚ stomach‚ small and large intestine‚ and the anus. There are also accessory digestive organs involved including the salivary glands‚ liver‚ pancreas‚ and gallbladder. Digestion begins in the oral cavity where

series of integrated changes in function that involve most‚ if not all‚ of its physiological systems. Movement requires activation and control of the musculoskeletal system; the cardiovascular and respiratory systems provide the ability to sustain this movement over extended periods. When the body engages in exercise training several times a week or more frequently‚ each of these physiological systems undergoes specific adaptations that increase the body’s efficiency and capacity. After a twelve

Circulatory system is an organ system where nutrients pass through. Cardiovascular and lymphatic systems make up the complete circulatory system. Arteries‚ veins‚ and the heart are the main organs in the circulatory system. Examples of nutrients that are passed through are electrolytes‚ amino acids and lymph. Also other substances passed through the specific organ system are gases‚ hormones and blood cells to and from cells. The reason the substances are passed through the circulatory system is to fight
