HESI Anatomy and Physiology Practice Test
The HESI anatomy and physiology will include 25 interrogations in anatomical plane and orientation, histology; mitosis and meiosis; and body systems. Each section will cover other relevant points related to these areas. Additional data and test queries for each section are as follows.
Welcome to the free HESI anatomy and physiology.
The attached sample test contains 10 HESI anatomy and physiology problems, so you can accurately understand the preparation of the A&P position of the upcoming HESI test.
Each question will be accompanied by the correct answer and a clear explanation of the solution (actually like using the bank query in our HESI practice test package).
At the end of the training test, you will get a score report that separates the sub-points that you should return to zero for quick improvement.
If it is not too troublesome, please let us know how you comment and make sure to share this article with your peers, who may also think it is helpful to you.
Which of the following is NOT a digestive system function?
Correct answer: Performing gas exchange
Except for gas exchange, which is performed by the respiratory system, the digestive tract conducts all of the aforementioned activities. The digestive tract uses chemical digestion to break down food enzymatically. In the small intestine, nutrients are absorbed into the bloodstream. Unabsorbed waste is then evacuated from the large intestine via the anus.
What is the best way to define homeostasis?
Correct answer: a mechanism through which the body maintains a steady internal environment in the face of changes in internal and external circumstances
Homeostasis is the process through which the organism maintains a steady internal environment in the face of internal and external disturbances. The terms ‘homeo' and ‘stasis' relate to sameness and balance, respectively. Cellular respiration is the mechanism by which the body breaks down glucose to provide energy to power other cellular activities. Immunity is the mechanism through which the body reduces and responds to microbial infection. Phenotypic variation is the idea that describes how the organism maintains its genetic composition despite the fact that distinct cells perform various activities.
Which anatomical directional phrase refers to a bodily component that is positioned in front of the body?
Correct answer: anterior
The term anterior refers to a bodily portion that is positioned in front of the body.
What is the body's biggest organ?
Correct answer: skin
Despite its low thickness, the skin is considered an organ and hence the biggest in the body due to its enormous surface area. The skin is an essential component of the integumentary system. The small intestine and stomach are both important digestive organs, although neither is the biggest organ in the body. The small intestine, which is responsible for digestion and nutrient absorption, is the longest portion of the digestive system, while the large intestine is the biggest. The femur is the body's biggest bone, yet it is not the largest organ.
What's the connection between sarcomeres, myofibrils, and muscle cells?
Correct answer: Muscle cells include myofibrils, which are composed of sarcomeres.
Muscle fibers are another name for muscle cells. Myofibrils, which are made up of sarcomeres, are found in abundance in each muscle cell. A sarcomere is a myofibril segment that includes actin and myosin that glide across each other, causing muscle contraction.
Which of the following is the most abundant component of whole blood?
Correct answer: Plasma
Plasma, the liquid part of blood, accounts for about 55% of total blood volume, with the remaining 45% mostly made up of red blood cells, or erythrocytes. White blood cells and platelets account for a very tiny proportion of total blood volume.
What type of tissue supports and structures the organs?
Correct answer: Connective
Connective tissue acts as the body's scaffolding, providing support and structure to the organs. Connective tissue is the most common, widespread, and diverse form of tissue. Ligaments, tendons, fat, cartilage, bone, bone marrow, and blood are all part of it. Connective tissues, as the name indicates, frequently link organs together, hold organs in place, cushion them, and fill space.
What is the name of the tube that links the larynx to the bronchi?
Correct answer: Trachea
The trachea links the larynx to the bronchi.
What is the purpose of the extensor muscles?
Correct answer: Increase the joint angle
Extensors make the joint angle larger. Extensor muscles are those that, when contracted, extend or straighten a limb or portion of the body.
What is the hormone that assists estrogen in stimulating the formation of the endometrium?
Correct answer: progesterone
Progesterone is a hormone generated by the ovaries that is responsible for the maintenance of the uterine lining, also known as the endometrium.
How many types of basic tissues does a human have?
Correct answer: 4
Humans have four fundamental tissue types: epithelial, connective, nervous, and muscular.
Which of the following organ systems is responsible for creating movement via contraction?
Correct answer: Muscular
Muscles exist solely to create movement through contraction.
Which of the following is the most accurate definition of the term circulation?
Correct answer: The cardiovascular system transports oxygen and other nutrients to the tissues
The cardiovascular system transports oxygen and other nutrients to the tissues via circulation.
Which of the following words refers to being near to the body's trunk?
Correct answer: Proximal
Proximal refers to being close to the body's trunk.
What is meant by the word optic?
Correct answer: The eye or vision
Optics relates to the eye or how light is perceived.
What is called by the release of prolactin during breastfeeding?
Correct answer: Positive feedback
Prolactin activating the mammary glands in the breast is an example of positive feedback. The more a mother breastfeeds, the more prolactin is released and milk is produced. When the stimulus is removed/satisfied, negative feedback implies that a process is "turned off." Gene regulation, protein synthesis, and cell permeability are not suitable answers to the issue.
What would happen if the phrenic nerve was injured?
Correct answer: Inability to control one's breathing
The phrenic nerve regulates breathing and diaphragm movement. If this region is damaged, the diaphragm will not get the required signals to contract and/or relax, making breathing on one's own exceedingly difficult or impossible.
Which valve is in charge of stopping blood from flowing backward from the right ventricle to the right atrium?
Correct answer: Tricuspid valve
The pulmonary valve and the semilunar valve are the same mechanism that prevents blood from flowing backwards between the right ventricle and the pulmonary artery. The mitral valve is situated between the left ventricle and the left atrium of the heart. The aortic valve is a structure that connects the left ventricle to the aorta. The tricuspid valve is the only valve found on the right side between the right atrium and right ventricle.
Which kind of circulation is connected with the right side of the heart?
Correct answer: Pulmonary circulation
The right side of the heart collects deoxygenated blood from the upper and lower bodies. The right side of the heart's major function is to collect blood and transmit it to the lungs to absorb oxygen. This procedure refers to the pulmonary circulation. The movement of oxygenated blood from the left side of the heart to the upper and lower parts of the body is referred to as systemic circulation. The circulatory system does not include aortic, ventricular, or myocardial circulation.
Which of the following does the diaphragm perform during exhalation?
Correct answer: Relaxes and lifts
To drive the air out, the air pressure in the lungs must rise above atmospheric pressure during exhalation. The diaphragm must relax and raise in order for this to happen. During inhalation, the diaphragm contracts and lowers to enable more space in the lungs for air to enter.
