Systems of the Human Body Trivia Quiz

Answer: Digestive

The function of the digestive system is to absorb nutrition into the human body, and remove the various waste products. Strictly speaking, the mouth and oesophagus are also part of the system, in that they enable food to enter the body and transfer it to the stomach, where the process of digestion begins.

The majority of digestion takes place in the small intestine, before waste products are passed out through the anus.

Answer: Pancreas

The basic elements of the human musculoskeletal system are the bones, plus the muscles, tendons and ligaments that connect them together. As well as providing a framework and protection for the internal organs, the structure of the musculoskeletal system enables the different parts of the body to move in an incredibly controlled and precise manner.

The pancreas is an internal organ that is part of the digestive system.

Answer: Neurons

The nervous system enables the brain to receive and transmit information almost instantaneously around the body. The human nervous system consists of billions of neurons that connect to form nerves, through which this information is transmitted. The central nervous system (consisting of the brain and spinal chord) is connected to the rest of the body by the peripheral nervous system.

Answer: Respiratory

The human respiratory system has evolved to get air in and out of the lungs. When you breathe in, air is carried to the lungs, and oxygen is passed from the air into red blood cells, whence it is carried (via the heart) to the rest of the body. At the same time as oxygen leaves the lungs, carbon dioxide enters them, and this is ejected when you breathe out.

Answer: lymph

Lymph is a clear fluid that circulates through the body in lymphatic vessels. It carries plasma that has been removed from the circulatory system. It also plays an important part in the immune system, by carrying white blood cells to the parts of the body where they are needed, for example to fight an infection.

Answer: Colon

The colon is another name for the large intestine, and is part of the digestive system. All of the others are glands and produce a variety of hormones, which are secreted into the circulatory system. To give just one example, the pituitary gland (situated at the base of the brain) secretes a beta-endorphin hormone, which inhibits feelings of pain.

Answer: True

The immune system, as its name suggests, has as its main function the protection against disease. White blood cells are also known as leukocytes, and are produced in healthy bone marrow. They are carried around the body in the blood, and search for and destroy viruses and bacteria that could other wise cause illness and disease.

Answer: Arteries

The heart is the centre of the circulatory system. Veins carry deoxygenated blood to the heart, while arteries (mostly) carry oxygenated blood away from it. As you might expect in such a complex system, there are a couple of exceptions, namely the umbilical and pulmonary arteries, which contain deoxygenated blood.

Answer: Integumentary

This diagram shows a cross-section of a layer of human skin. The outer layer is known as the epidermis, underneath which are the dermis and the subcutis or hypodermis. One odd fact about your skin: while most of it is waterproof, there is one exception - the skin on the inside of the mouth.

Answer: Kidney

The kidneys, of which most people have two, carry out a vital role in producing urine, which is used to carry waste matter out of the body. During its journey round the body, blood travels through the kidneys, during which process many undesirable chemicals are filtered out. The resulting liquid is then stored in the bladder until it is expelled from the body in urine.
