Introduction to Anatomy and Physiology

Anatomy means the structure of the human body. Ana (making) Tomy (cutting.) Physiology means the study of normal human body’s functions. Physio (physical) Logy (study.) There are two different types of anatomy, which are Gross Anatomy and Microscopic Anatomic. Gross Anatomy refers to the structures that can be seen with the eyes. For example: the heart, the liver, and the kidneys. There are several subdivisions of Gross Anatomy such as; surface anatomy, regional anatomy, and systemic anatomy. Surface anatomy focuses on the external parts of the body. For example: legs and head. Regional anatomy focuses on all the structures in a specific region of the body. For example: examining the buccal region of

Chemical level is the smallest unit of matter. For example: atoms. Cellular level is the smallest living units in the body. For example: lung cell, kidney cell. Tissue level is the group of similar cells that work together to do a similar function. For example: the bladder and kidneys. Organ level is based on two or more tissues working together to perform a specific function. For example: the liver is made up of different tissues working together. The organ system consists of organs interacting together. For example: heart, blood, and blood vessels. Lastly, the organism level is the all the organ systems of the body working together to maintain life. For example: the human …show more content…
The integumentary system provides protection and regulates body temperature. Some major organs are: hair, skin and toenails. The skeletal system provides support and protection. Some major bones are; skull, rib, sternum, and cartilage. The muscular system produces body movement. Some major muscles are the tendons and pectoralis. The nervous system is the central control of our body. It responds to sensory stimuli. Its major organs are the brain, the spinal cord, and the sense organ. The endocrine system controls different organs in the right direction. Some major organs of the endocrine system are thymus, hypothalamus, pancreas and kidneys. The cardiovascular system consists of the heart and blood vessels. The heart moves blood through blood vessels to distribute hormones and nutrients. The lymphatic system defends against infection and disease. The respiratory system is responsible for exchange oxygen and carbon dioxide between and the air in the lungs. The urinary system filters the blood to remove waste products in the form of urine. The digestive system digests food materials, absorbs nutrients and expels waste products. The reproductive system produces sex

    This circuit carries blood to all the nooks and crannies of the body excluding the lungs. In the systemic circuit, the newly oxygenated blood, from the pulmonary circuit, leaves the body through the left ventricle to the aorta, and enters the arteries and capillaries where it supplies the body 's tissues with oxygen. The now oxygen-depleted blood returns back to the heart, completing the circuit. The pulmonary and systemic circulations are on a continuous loop, pumping blood to and from the heart. The heart is critical to the body for survival because it pumps the blood and nutrients that the…

    The duodenum has a unique feature of the Brunner’s gland, this specifically neutralises the acid chyme produced by the stomach. The chyme is blended with pancreatic enzymes, and molecules are absorbed into the enterocytes, proteins are broken up by pepsin from gastric glands and then further broken down by trypsin, chymotrypsin, elastase and carboxypeptidases. Carbohydrates are hydrolysed by amylases and membrane bound enzymes convert sugars to monosaccharides. Lipids are emulsified in the stomach and then further emulsified in the duodenum by pancreatic lipases, small lipid molecules are absorbed by…

    They attach to tissues or organs, which are known as targets (Herlihy, 2014). These targets are receptor cells, which are either external and located on cell membranes or internal, within the cell (Herlihy, 2014). There are many glands throughout the body, with the main glands being the, hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid gland, thymus gland, adrenal gland, pancreas and the gonads (Herlihy, 2014). The endocrine system is a vital system needed to function optimally to secrete hormones into the blood to be carried around the body to particular sites to then control tissues and organs (Herlihy,…
