If You Get 29/35 on This Quiz, You Can Fake Your Way Through the MCAT

The MCAT is the Medical College Admission Test used by institutions in the United States. If you want to be a medical student, you have to pass this critical exam.

Most vertebrates have a spleen, and one of its primary functions is in support of the immune system. It creates antibodies that ward off infections.

In a lot of living cells, scientists find protein tubules and filaments that make up the cytoskeleton. The cytoskeleton gives the cell shape and structure.

You don’t need to wash your hands, ever. You're already teeming with other lifeforms. Some scientists estimate that 90% of the cells in a human body are bacteria.

As vertebrate embryos develop, the nervous system grows and evolves. Neural plates turn into neural tubes, and the central nervous system begins to take shape.

The lymphatic system is an often unsung hero of the human body. With its nodes and ducts, it transfers toxins and wastes​ out of the body before it can do serious harm.

Mitochondria are often called the powerhouses of the cell. They use oxidative metabolism to turn food into energy that organisms need to survive.

When the body loses some (or all) of its ability to fight of critters like harmful bacteria or viruses, it's in a state of immunodeficiency. Severe immunodeficiency often causes death.

Cells are basic blocks of life, and all cells are motile objects thanks to their ability to divide into new cells. They are organisms that can move independently.

Angiotensin II can be used to help with hypotension in the circulatory system. Hypotension can often happen due to septic shock.

In the right conditions, certain types of bacteria can move across surfaces using what's called swarming motility. Plentiful food and moderate temperates make many bacteria thrive.

Biosignals are any measureable signal in organisms. EEGs and MMGs are methods used to measure brain activity and muscle contraction, respectively.

In the U.S., Medicare is a vital tool for many older Americans who would otherwise go without health care. Medicaid, on the other hand, is often meant for anyone who doesn't have the resources to get regular health care out of pocket or perhaps through an employer.

In adults, bone marrow is the hub of hematopoiesis​, the creation of blood. One person might create 100 billion new red blood cells each day.

In 1665, Robert Hooke became the the first person to observe cells. His use of a primitive microscope altered the course of science, making it possible for humans to see very tiny cells.

Cacteria and archaeans are two type of prokaryotic organisms. They have a cell nucleus that isn't contained within a well-defined membrane.

Ribonucleic acid or RNA, is a lot like DNA. Both carry the genetic coding that's critical for instructing the activities of various body cells.

Extremophiles are microorganisms that can survive in harsh conditions, from very high or low temperatures, alkalinity, or wild chemical concentrations. They are typically archaeans.

Eukaryotic cells have a nucleus and multiple types of organelles. Organelles ha​ve specific jobs, from creating energy to generating new hormones.

Electrodermal activity is a term used to describe the varying electrical traits of skin. It's is also commonly called galvanic skin response or skin conductance response, among other terms.

Eukaryotes are cells that have a well-defined nucleus tucked away behind a membrane. These kinds of cells can reproduce either sexually or asexually.

Stroma is the structural tissue that helps organs maintain their shape and function. Parenchyma, on the other hand, describes the functional parts of the organ.

A conversion disorder is manifested by a sensory or motor problem … but it's one that has a psychological cause, not one that's rooted in issues with the body.

Germinal centers are found within the lymphatic system and the spleen. They're incredibly important as part of the body's immune system.

Cultural capital is a bit like monetary capital -- it's an advantage bestowed on the elite due to their standing in society.

When nonhomologous chromosomes have parts that are rearranged, you wind up with chromosomal translocation. It's an abnormality that can cause a variety of issues with extra or missing genes.

Social norms are established rules of behavior that vary from culture to culture. In the U.S., no one tells their doctor or dentist they love them during a routine exam … unless they're family. Or, you know, nuts.

Feeling mortal yet? Each and every second, about 2 million of your blood cells die. If you listen closely, you may hear some of them screaming, "banazi!"

Proteins do all sorts of fantastic things in the human body. But they don't self-replicate like DNA.

In generalization, a specific stimulus creates a conditioned response. In this example, you've learned to associate all cooked beef with the burger that made you violently ill.
