![]() ![]() The nasal and oral cavities are continued by the pharynx, commonly called the throat. The neck serves as a passageway between the head and thorax. ![]() These are involved in a variety of functions, like vision, smell, hearing, eating and speaking, to name a few. The head comprises several associated structures, such as eyes, a nose, ears, and a mouth. It consists of several bones joined together that form the bony skull, or cranium, parts of which enclose the brain, and some which form the facial skeleton. Now that we’ve covered some basics, let’s focus on the head. Vital nerves and blood vessels pass through the neck while traveling between the head and the rest of the body, so understanding these regions is important. Knowing these structures by heart will help you to easily access and describe vital functions.Ī strong and mobile neck supports a five-kilogram head, which in turn contains the brain. More details are provided below:įor a lot of students, the head and neck will be the next topic on your anatomy curriculum. They form entire systems that work in unison to ensure that you eliminate wastes, react to stressful or scary situations, and reproduce. It's easy to think that the abdomen and pelvis are already overfilled with the structures of the gastrointestinal tract, but there is in fact more! Organs like the kidneys, ureters, urinary bladder, and several reproductive structures are also located here. They help especially with the digestion of proteins and fats, as well as metabolic processing. The intestines, which are mainly responsible for absorption, snail through these regions for a total of 7.5 meters, the equivalent of four human beings stacked upright on top of each other.įour important accessory organs that help the gastrointestinal tract to perform its functions are the liver, gallbladder, pancreas, and spleen. The largest organ system located here is the gastrointestinal tract. These two regions are often taught separately for didactic purposes, but their contents blend together into one large abdominopelvic cavity. Read on to find out more!Ĭontinuing inferiorly to the thorax, we find the abdomen and pelvis. ![]() This vital organ pumps 5 liters of blood every minute of your waking day through the entire body. ![]() Sandwiched between the lungs is the mediastinum, a space that contains blood vessels, nerves, lymphatics, and most importantly, the heart. Altogether, the lungs occupy a surface area equivalent to the size of a tennis court. Internally it consists of the thoracic cavity that, first and foremost, houses the lungs. The thorax is as complex on the inside as it is on the outside. This region can be considered the epicentre of the circulatory system and the primary player in breathing, the latter function being mainly controlled by the diaphragm. In the world of anatomy, the chest is called the thorax and it is located between the neck and the abdomen. Learning these will help you to be prepared in cases of emergency and also in caring for patients with chronic disorders. Impairments of the heart and the lungs can easily lead to life-threatening conditions. Let’s begin with those found in the thorax. You’re now ready to learn about one of the most interesting topics in anatomy - internal organs. ![]()
