A Journey Through the Human Body Quiz

Answer: cerebrum

It is the neural tissue covering the cerebrum that is referred to as gray matter. The cerebral cortex plays a key role in memory, thought, language and perceptual awareness.

Answer: temporal

The hippocampus is one of the first areas to become affected when a person, often the elderly, suffers from Alzheimer's disease. The word hippocampus comes from the combination of the Greek word for horse, 'hippos,' and the word for sea monster,'kampos,' since the structure looks somewhat like a sea horse.

Answer: plasma-like fluid between the lens and iris

The aqueous humor maintains both the pressure in the eye and the eye's shape. Its fluid is secreted by the ciliary body which is located behind the iris at the front of the eye. The vitreous humor is a clear liquid located at the back of the eye behind the lens and in front of the retina. Light passes through this substance in order to help process visual data.

Answer: help carry air into the lungs

The bronchi are two air tubes that branch off from the trachea and carry air to the lungs. When we breathe the air travels into the larynx, through the trachea, and then into the left and right bronchus on the way down to small sacs called alveoli which is where the exchange of oxygen and carbon dioxide takes place.

Answer: sternum

Also called the sternum angle, it's located between the manubrium and the sternal body. The sternum angle is structurally significant in that it serves as the boundary between the inferior and superior mediastinum and as the highest point of the pericardial sac. The angle of Louis was named for Antoine Louis, an 18th century French physician.

Answer: aorta

The blood leaves the heart through the aorta, is carried by the arteries and returns through the veins. The carotid artery carries blood to the head and brain. The renal artery and vein supply blood to the kidneys. The iliac artery supplies blood to the pelvis and lower limbs and the femoral artery supplies blood to the thigh and lower leg.

Answer: neutrophils

The white blood cells belong to the body's lymphatic system. The main role of these cells is to protect against infection. It's the job of the lymphocytes to create antibodies which help destroy germs. The lymph nodes, tonsils, adenoids, spleen, and lymphatic vessels all play a part in keeping a person healthy.

Answer: ileum

There are many organs involved in the digestive process and each has its own function. The esophagus sends chewed food from the mouth down to the stomach. The liver processes and stores nutrients and also produces bile. The gallbladder stores bile which is needed to absorb fat.

The small intestine absorbs nutrients, minerals and liquids while the large intestine absorbs additional minerals and liquids. The colon absorbs any additional liquids while the rectum stores the waste products of digestion until they are expelled through the anus.

Answer: nephrons

Nephrons consist of two main parts: the glomerulus and the tubule. Unfiltered blood enters the nephron at the glomerulus where filtered water and waste pass on to the tubule. Any useful substances are reabsorbed in the tubule and then the remaining urine goes to the bladder. The kidneys are located at the back of the abdomen.

Answer: smooth

Most muscles in the body are skeletal. These are the muscles we control. Some examples of this muscle are the deltoid, diaphragm, soleus, and biceps femoris. The cardiac muscle only surrounds the heart and its automatic movement keeps the heart beating. The smooth muscles control movement of inner organs such as the bladder, intestines, womb, and stomach.
