Are you interested in learning more about how to obtain a diploma in a Medical Assistant program? Part of what you will learn during your Medical Assistant training are different terminology for anatomy and physiology.

You have probably heard this Billy Ray Cyrus song. Heartache, heartbreak Did you ever wonder why the heart is associated with love? The heart was once thought to be the center of all thought processes, as well as the site of all emotions. This notion may have stemmed from very early anatomical dissections that found many nerves can be traced to the region of the heart.

10.4: Human Organs and Organ Systems

You have probably heard this Billy Ray Cyrus song. Heartache, heartbreak Did you ever wonder why the heart is associated with love? The heart was once thought to be the center of all thought processes, as well as the site of all emotions. This notion may have stemmed from very early anatomical dissections that found many nerves can be traced to the region of the heart.

The fact that the heart may start racing when one is excited or otherwise emotionally aroused may have contributed to this idea as well.

In fact, the heart is not the organ that controls thoughts or emotions. The organ that controls those functions is the brain. An organ is a collection of tissues joined in a structural unit to serve a common function. Organs exist in most multicellular organisms, including not only humans and other animals but also plants.

In single-celled organisms such as bacteria, the functional equivalent of an organ is an organelle. The main tissue may be unique to that specific organ. The heart also includes nervous and connective tissues that are required for it to perform its major function.

For example, nervous tissues control the beating of the heart, and connective tissues make up heart valves that keep blood flowing in just one direction through the heart. The human body contains five organs that are considered vital for survival. They are the heart, brain, kidneys, liver, and lungs. The locations of these five organs and several other internal organs are shown in the figure below.

If any of the five vital organs stops functioning, the death of the organism is imminent without medical intervention. Functionally related organs often cooperate to form whole organ systems. The 12 diagrams in the figures below show 11 human organ systems, including separate diagrams for the male and female reproductive systems. Some of the organs and functions of the organ systems are identified in the figure.

Each system is also described in more detail in the text that follows. Most of these human organ systems are also the subject of separate chapters in this Flexbook. Organs of the integumentary system include the skin, hair, and nails. The skin is the largest organ in the body. It encloses and protects the body and is the site of many sensory receptors. The skeletal system consists of bones, joints, teeth.

The bones of the skeletal system are connected by tendons, ligaments, and cartilage. Functions of the skeletal system include supporting the body and giving it shape. Along with the muscular system, the skeletal system enables the body to move. The bones of the skeletal system also protect internal organs, store calcium, and produce red and white blood cells.

The muscular system consists of three different types of muscles, including skeletal muscles, which are attached to bones by tendons and allow for voluntary movements of the body. Smooth muscle tissues control the involuntary movements of internal organs, such as the organs of the digestive system, allowing food to move through the system. Smooth muscles in blood vessels allow vasoconstriction and vasodilation and thereby help regulate body temperature.

Cardiac muscle tissues control the involuntary beating of the heart, allowing it to pump blood through the blood vessels of the cardiovascular system. The nervous system includes the brain and spinal cord, which make up the central nervous system, and nerves that run throughout the rest of the body, which make up the peripheral nervous system. The nervous system controls both voluntary and involuntary responses of the human organism and also detects and processes sensory information.

The endocrine system is made up of glands that secrete hormones into the blood, which carries the hormones throughout the body. Endocrine hormones are chemical messengers that control many body functions, including metabolism, growth, and sexual development. The master gland of the endocrine system is the pituitary gland, which produces hormones that control other endocrine glands.

Some of the other endocrine glands include the pancreas, thyroid gland, and adrenal glands. The cardiovascular system also called the circulatory system includes the heart, blood, and three types of blood vessels: arteries, veins, and capillaries.

The heart pumps blood, which travels through the blood vessels. The main function of the cardiovascular system is transport. Oxygen from the lungs and nutrients from the digestive system are transported to cells throughout the body. Carbon dioxide and other waste materials are picked up from the cells and transported to organs such as the lungs and kidneys for elimination from the body. The cardiovascular system also equalizes body temperature and transports endocrine hormones to cells in the body where they are needed.

The urinary system includes the pair of kidneys, which filter excess water and a waste product called urea from the blood and form urine. Two tubes called ureters carry the urine from the kidneys to the urinary bladder, which stores the urine until it is excreted from the body through another tube named the urethra.

The kidneys also produce an enzyme called renin and a variety of hormones. These substances help regulate blood pressure, the production of red blood cells, and the balance of calcium and phosphorus in the body. Organs and other structures of the respiratory system include the nasal passages, lungs, and a long tube called the trachea, which carries air between the nasal passages and lungs.

The main function of the respiratory system is to deliver oxygen to the blood and remove carbon dioxide from the body. Gases are exchanged between the lungs and blood across the walls of capillaries lining tiny air sacs alveoli in the lungs. The lymphatic system is sometimes considered to be part of the immune system. It consists of a network of lymph vessels and ducts that collect excess fluid called lymph from extracellular spaces in tissues and transport the fluid to the bloodstream.

The lymphatic system also includes many small collections of tissue, called lymph nodes, and an organ called the spleen, both of which remove pathogens and cellular debris from the lymph or blood. In addition, the thymus gland in the lymphatic system produces some types of white blood cells lymphocytes that fight infections.

The digestive system consists of several main organs — including the mouth, esophagus, stomach, and small and large intestines — that form a long tube called the gastrointestinal GI tract.

Food moves through this tract where it is digested, its nutrients absorbed, and its waste products excreted. The digestive system also includes accessory organs such as the pancreas and liver that produce enzymes and other substances needed for digestion but through which food does not actually pass. The reproductive system is the only body system that differs substantially between individuals. There is a range of Biological sex, but most books divide them into male and female.

The male and female reproductive systems are shown separately because of their significant differences. However, you may have never heard of a penis transplant. The first U. The hour procedure involved a team of more than 50 physicians, surgeons, and nurses. The patient was a year-old man who had lost his penis to cancer in The surgical milestone involved grafting microscopic blood vessels and nerves of the donor organ to those of the recipient. As with most transplant patients, this patient will have to take immunosuppressing drugs for the rest of his life so his immune system will not reject the organ.

What are the three organ systems involved in regulating human body temperature? True or False. The respiratory system helps to remove wastes from the body.

Professor Anthony Atala is working to answer an important question: Can we grow new replacement organs rather than transplanting organs from other people? In his state-of-the-art lab, he and his associates are actually growing human organs, including blood vessels, bladders, and kidneys.

Watch the fascinating TED talk below to see how they are doing it. While organ transplant saves countless lives, they oftentimes fail. Learn more here:. Human Organs An organ is a collection of tissues joined in a structural unit to serve a common function. Vital Organs The human body contains five organs that are considered vital for survival. The heart is located in the center of the chest, and its function is to keep blood flowing through the body. Blood carries substances to cells that they need and also carries away wastes from cells.

It is the seat of all thoughts, memories, perceptions, and feelings. The two kidneys are located in the back of the abdomen on either side of the body. Their function is to filter blood and form urine, which is excreted from the body. The liver is located on the right side of the abdomen. It has many functions, including filtering blood, secreting bile that is needed for digestion, and producing proteins necessary for blood clotting.

The two lungs are located on either side of the upper chest. Their main function is exchanging oxygen and carbon dioxide with the blood.

List of systems of the human body

The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul. Intelligence, creativity, emotion, and memory are a few of the many things governed by the brain. Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem.

Стратмор убил Чатрукьяна. Хейл, видимо, не догадывается, что она видела его внизу. - Стратмор знает, что я это видел! - Хейл сплюнул.  - Он и меня убьет. Если бы Сьюзан не была парализована страхом, она бы расхохоталась ему в лицо. Она раскусила эту тактику разделяй и властвуй, тактику отставного морского пехотинца. Солги и столкни лбами своих врагов.

Сотрудники почтительно кланялись, когда он проходил мимо. Нуматака хорошо понимал, что эти поклоны вовсе не свидетельствует об их любви к нему, они - всего лишь знак вежливости, которую японские служащие проявляют по отношению даже к самым ненавистным начальникам. Нуматака проследовал прямо на коммутатор компании.
