Bronchi vs Bronchioles The human respiratory system is basically made up two lungs, located inside the upper part of the body cavity. Lungs increase the gas exchange surface area while minimizing the evaporation. However, the gas exchange takes place deep in the lungs, in alveoli, which are found at the end of a long […]

Difference Between Afforestation and Reforestation
Afforestation vs Reforestation Afforestation and reforestation are the converse of avoiding deforestation. According to the United Nations Framework Convention on Climate Change (UNFCCC), these terms are defined as direct human induced conservation of non- forested lands back to forested lands with the help of activities such as planting, seeding, and human- induced promotions of […]
Difference Between Adenine and Guanine
Adenine vs Guanine Nuclear acids are nucleotide polymers, which contain four different nucleotide bases; adenine, guanine, cytosine, and thymine (uracil in RNA). These four bases can be put into two major categories namely purines and pyrimidines. Adenine and guanine are the purines while cytosine, thymine, and uracil are the pyrimidines. To keep the same […]
Difference Between Sphagnum and Peat Moss
Sphagnum vs Peat Moss Mosses are a botanical division which is commonly referred to as Division Bryophyta. Bryophytes include most primitive plant species that typically grows up to 10 cm tall. These tiny plants do not have flowers and seeds. Their stem is covered with simple leaves. There are about 14,500 species of bryophytes […]
Difference Between Sensory and Motor Neurons
The key difference between sensory and motor neurons is that the sensory neurons are the neurons that carry information from sense organs to the central nervous system while motor neurons are the neurons that carry information from the central nervous system to the muscle cells. Neurons are the functional and structural units of the vertebrate […]
Difference Between Sensory and Motor Nerves
Sensory vs Motor Nerves The nervous system controls all activities of the body, both voluntary and involuntary. The somatic nervous system regulates all the voluntary controlled activities such as walking, talking etc. while the autonomic nervous system controls the activities under involuntary control, such as digestion, dilation etc. (Read more: Difference Between Somatic and […]
Difference Between Atria and Ventricles
The key difference between atria and ventricles is their function. Atria receive blood from body parts and lungs and pass the blood to ventricles, which then pump the blood received from atria to the body parts, including the lungs. The human circulatory system has a four-chambered heart with two separate atria and two separate ventricles. The main […]
Difference Between Cervix and Uterus
Cervix vs Uterus Uterus and cervix are important muscular structures of the reproduction system in females. These structures facilitate the development of embryo and fetus during pregnancy. In nonpregnant periods, uterus and cervix help to maintain the menstruation cycle and provide protection for the reproduction system of females. The physiologies of uterus and cervix […]
Difference Between Stem Cells and Embryonic Stem Cells
Stem Cells vs Embryonic Stem Cells Stem cells are a unique type of cells that are capable of giving rise to specialized cell types in the body. In addition, they are unspecialized and have the ability to divide and renew themselves for long periods. Several types of stem cells have been found from germ […]
Difference Between Ovary and Uterus
Ovary vs Uterus The female reproductive system of human is basically composed of internal structures including ovaries, fallopian tubes, uterus, cervix, and vagina and external structures including vulva, labia majora, labia minora, clitoris, vestibule, hymen, vaginal orifice, and vestibular glands. The main functions of this system include generation of eggs (oogenesis), the transportation of […]
