FREE General Anatomy Questions and Answers
Which of the following tissue types performs the role of lining, protecting, and covering surfaces and bodily cavities?
Epithelial tissue serves as the lining and covering of the body's cavities and surfaces.
Organs that enable gas exchange between the blood and the outside environment make up the respiratory system. Which of the following best characterizes the organ group involved in gas exchange?
Which of the following best sums up how cells breathe?
Anabolic reactions employ energy to create the compounds that the organism needs. In a "catabolic process," complex molecules are broken down into simpler ones to provide energy the organism can use.
An element loses one or more electrons to oxygen during oxidation.
An element gains one or more electrons during reduction.
The process by which a cell takes in oxygen and uses it to break down glucose to produce energy in the form of ATP is known as cellular respiration. The electron transport chain, the last phase of cellular respiration, is where oxygen absorbs electrons and picks up protons to create water. Therefore, cellular respiration is both a "oxidative" and "catabolic" activity because oxygen causes elements to lose electrons and because it is a reaction in which energy is produced.
What is the proper ranking of structures, from the simplest to the most complex?
The fundamental cells that make up the nervous system are called neurons. The mitochondria will be the simplest structure on the list because it is an organelle that can be found inside a neuron. The brain is made up of nervous tissue, which is composed of many neurons.
Which of the following is not a part of the human body's anterior region?
Backwards is where the spinal column is situated (at the back). Anteriorly are the clavicle, sternum, and mandible (front).
HIV is a virus that damages the host's immune system by integrating itself into its DNA. What region of the infected host cell does the HIV virus reside in?
By fusing its genetic material with that of the host cell, HIV infects the host cell. The nucleus is where the genetic material is located.
Osteoblasts are specialized cells that release compounds important for the creation of bones, including the protein collagen. In osteoblasts, which of the following organelles is more likely to be dominant?
Since ribosomes are the organelles in charge of protein synthesis, it makes sense that they would predominate in cells that secrete protein, like osteoblasts.
Which of the following procedures best describes how new cells are created during injury to replace worn-out and damaged ones?
"Two distinct cell division processes are meiosis and mitosis.
A single cell divides into two identical daughter cells during the process of mitosis. Mitosis is mostly used to replace harmed and worn-out cells."
Which statement about anatomical position is accurate?
White blood cells have a large number of ______ because they must get rid of dangerous invaders like germs and viruses. Which of the following choices fully completes the preceding statement?
Because they must get rid of dangerous invaders like bacteria and viruses, white blood cells have more lysosomes than other blood types. Waste from a cell is broken down and eliminated by lysosomes. This indicates that they can destroy germs and viruses that the body attempts to defend itself against by engulfing them in white blood cells.
Which of the following organ systems matches its role correctly?
Through hormone signaling, the endocrine system is in charge of managing homeostasis.
