Liver: The liver has many functions, but two of its main functions within the digestive system are to make and secrete bile, and to cleanse and purify the blood coming from the small intestine containing the nutrients just absorbed.

Gallbladder: The gallbladder is a pear-shaped reservoir that sits just under the liver and stores bile. Bile is made in the liver then travels to the gallbladder through a channel called the cystic duct.Large intestine: The large intestine performs the vital functions of converting food into feces, absorbing essential vitamins produced by gut bacteria, and reclaiming water from feces. Additional absorbs water and any remaining nutrients and changes the waste from liquid into stool.Stomach: is a sac-like organ with strong muscular walls. The stomach secretes acid and powerful enzymes that continue the process of breaking down the food.Small intestine: Made up of three segments, the duodenum, jejunum, and ileum, the small intestine is a long tube loosely coiled in the abdomen. The small intestine continues the process of breaking down food by using enzymes released by the pancreas and bile from the liver.

Appendix: The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria, rebooting the digestive system after diarrheal illnesses.

Heart: The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.Kidney: The kidneys function is to filter the blood. All the blood in our bodies passes through the kidneys several times a day. Each kidney contains around a million units called nephrons, each of which is a microscopic filter for blood.

Lungs: The cone-shaped lungs are sponge-like organs that fill the chest cavity and make up most of the lower respiratory tract. Their most important job is providing oxygen to capillaries so they can oxygenate blood. Each lung is divided into lobes. The right lung has three, but the left lung has only two, thus allowing room to accommodate the heart.

Vagina: The cervix is found at the end of the vagina and is the opening of the uterus.The cervix will stretch, soften and dilate at the time of birth to allow passage of the baby from the uterus into the vagina and then out of the females body.Uterus: is a female reproductive organ located between the bladder and the rectum, in the pelvic area. The main purpose of the uterus is to nourish a fetus prior to birth. In menstruating females, the ovaries release eggs that travel via the fallopian tubes to the uterusOvaries: There are two ovaries and one is located on each side of the uterus. They produce eggs and other hormones. Ligaments and blood vessels support the ovaries.Fallopian tube: These tubes connect the ovaries to uterus. The fimbria or fingers of the fallopian tube capture an egg after it is released by the ovary and guide it into a fallopian tube. The egg then travels down the fallopian tube into the uterus.

Epididymis: These coiled tubes sitting on top of each testicle and help bring sperm to maturity. The epididymis also transports and stores sperm. These structures help to push sperm into vas deferens during sexual arousal.Vas deferens: This is a muscular tube that connects each epididymis to the penis. Sperm travel from the testicles through each epididymis and then through the vas deferens to the urethra (inside penis) during ejaculation.Ejaculatory ducts: These ducts are formed by the fusion of vas deferens and seminal vesicles. They empty their contents into the urethra during ejaculation.Urethra: This tube passes from bladder through penis to outside of body. Its function is to transport sperm during sex and also urine during urination. During intercourse, blood flow blocks urine from entering the urethraSeminal vesicles: These sacs produce fluid containing sugar for the health and nutrition of sperm. The seminal vesicles produce the majority of volume comprising the ejaculate fluid.

FindingThis work was based primarily on the internal organs of the human body as we saw are very important for everyone because without them our health would present difficulties could lose critical and life

It was very important for us to have done this investigation as we nourish our knowledge rot

Introduction

This work is based mainly on the internal organs of human body, as discussed below Organs are a set of tissues that perform a specific function. It's all part of the body that consists of complex tissues, which together with other components, helps the proper functioning of the body. There are various organs such as:-Brain-The heart-Lungs-The kidneys .etc.

the organs of the human body.organs are a collection of different tissues which form a structural unit in charge of compliance with a particular function within a multicellular organism.in the human body we can find the following organs:

Brain: It is a very complex organ and performs complex and important functions. Encased in the skull; it has the same general structure as the brains of other mammals, but is over three times the brains of other mammals with an equivalent body size. Most of the cerebral cortex is a folded layer neural tissue that covers the surface of the forebrain. Especially large are the frontal lobes, which are associated with executive, such as self-control, planning, reasoning and abstract thinking functions. The part of the brain associated with vision is also greatly enlarged in humans.
