First, the kidneys filter the blood through their respective nephrons, removing waste products like urea, creatinine and maintaining the proper balance of electrolytes and turning the waste products into urine by combining them with water from the blood. A faringe é um tubo que serve de passagem tanto para os alimentos quanto para o ar, portanto, faz parte do sistema respiratório e do sistema digestório.

For example, the nervous system and the endocrine system operate together as the neuroendocrine system.

Risk factors for coronary artery disease include obesity, smoking, high cholesterol, high blood pressure, lack of exercise and diabetes. Each alveolus is surrounded by capillaries carrying deoxygenated blood, which absorbs oxygen out of the air and into the bloodstream. The study of human physiology began with Hippocrates in Ancient Greece, around 420 BCE, and with Aristotle (384–322 BCE) who applied critical thinking and emphasis on the relationship between structure and function. Rilegatore di Libri considerati patrimonio dell'umanità, creati completamente a mano con le tecniche del XVI e XVII secolo. After ovulation, the portion of the follicle that remains in the ovary is transformed into a corpus luteum which continues to produce estrogen and high levels of progesterone.Os seus elementos constitutivos fundamentais son hidróxeno (H), osíxeno (O), carbono (C) e nitróxeno (N), presentándose outros moitos elementos en proporcións máis baixas (algúns, en proporcións moi baixas, os denominados oligoelementos). Any ambiguous image not easily fitting into one of these categories may be misinterpreted, leading to disputes.

Decúbito lateral esquerdo ou dereito: persoa deitada coas penas estendidas e brazos paralelos sobre o lado esquerdo ou dereito.The external male reproductive system is made up of the penis and the scrotum which is a sac containing the testicles. These molecules take the form of proteins (which are broken down into amino acids), fats, vitamins and minerals (the last of which are mainly ionic rather than molecular). Para isso, ele funciona como uma bomba dupla, o seu lado esquerdo bombeia sangue oxigenado (arterial) para diversas partes do corpo.

After being swallowed, food moves through the gastrointestinal tract by means of peristalsis: the systematic expansion and contraction of muscles to push food from one area to the next. The primary purpose of the reproductive system is to produce new humans in the form of children and ensure their sexual development so that they can produce new humans too.

The gallbladder is a hollow pear shaped organ located posterior to the inferior middle part of the right lobe of the liver. However, not all cells have DNA; some cells such as mature red blood cells lose their nucleus as they mature. A viewer recently submitted this incredible arm tattoo on one of her students at City College of San Francisco. Vesalian illustrations include the contemplative skeleton man (leaf 28r); and the muscle man with diaphragm (leaf 71 r). Consequently, the atria allow a cardiac output roughly 75% greater than would be possible without them.

Claude Bernard (1813–1878) created the concept of the milieu interieur (internal environment), which Walter Cannon (1871–1945) later said was regulated to a steady state in homeostasis. All major bones, muscles, and nerves in the body are named, with the exception of anatomical variations such as sesamoid bones and accessory muscles. imprescindíbel para a existencia do ser humano, que non pode estar sen beber máis de cinco ou seis días sen poñer en risco a súa vida.O corpo humano componse de cabeza, tronco e extremidades; os brazos son as extremidades superiores e as pernas as inferiores.
