Anatomy and Physiology Cell Organelles There are 50 trillion (50 million million) cells in the human body; they carry out chemical reactions essential to life, for example Blood cells. Nucleus The nucleus is the largest structure in any human cell, it contains gasps or pores, which allow protein and nucleic acid, pass through. It is the central part of the cell and it’s usually a lot darker than the rest of the cell because it absorbs stain quickly and stores the entire DNA (Deoxyribonucleic

variety of purposes, both functional and structural. The cardiovascular system consists of the heart, blood vessels and blood. It's a relatively simple -- though critically important -- body system, in that it operates much like a pump and series of pipes through which water might move. The purpose of the system is to circulate oxygen to your body cells, but also to circulate nutrients. Your blood then returns the waste products -- including carbon dioxide -- of various metabolic reactions to the

are pancreas, kidneys and skin. The respiratory and cardiovascular systems work in conjunction to maintain the body’s internal balance. The cardiovascular system relates to the circulatory system, which consists of the blood, the heart and blood vessels. (Tortora, p.546). The blood carries oxygen and nutrients from the lungs to the cells and tissues of the body and removes carbon dioxide and other waste from the cells to the lungs (www.medicinenet.com). The respiratory system includes the organs involved

The Atrium is part of the circulatory system. The atrium is a portion of the blood collection chamber of the heart. It is also sometimes called the auricle, although in the technical sense, the auricle is a separate part of the main atrium the right atrium receives deoxygenated blood from the superior vena cava, inferior vena cava and coronary sinus. The left atrium receives oxygenated blood from the left and right pulmonary veins. The atrium is also connected to the repertory system. The brain

help regulate the volume and composition of blood by the production and excretion of urine. This drainage system is carried out by nephrons, the functional unit of the kidney, in three subsequent steps: filtration, reabsorption and secretion. When blood enters the renal artery of the kidneys, the blood plasma is filtered by blood pressure forcing fluid across the glomerulus capillary membranes. Glomerular filtration creates a plasma-like filtrate of the blood. Filtrate moves through the proximal convoluted

(Dzugan, 2005). Heart disease can take many forms. Different arteries supply different areas of the heart with oxygenated blood. If one or more of these arteries became narrowed or clogged as a result of coronary artery disease, or atherosclerosis the artery cannot fully supply the part of the heart it is responsible for. The heart is an effective pump only when good blood supply is maintained to all heart muscles. Most women are not aware that heart disease is a greater risk for them than breast
