The key difference between single and double circulation is that in single circulation, blood travels once through the heart during a complete cycle, while in double circulation, blood flows twice through the heart during a complete cycle. The heart and lungs play an important role in circulation. The heart is the organ that pumps blood […]
Difference Between Terminal and Respiratory Bronchioles
The key difference between terminal and respiratory bronchioles is that terminal bronchioles are the last component of conducting division of the respiratory tract while respiratory bronchioles mark the beginning of the respiratory division. The respiratory system consists of different parts such as nasal cavity, nasopharynx, larynx, trachea, bronchi and bronchioles. There are two major divisions […]
Difference Between HFpEF and HFrEF
The key difference between HFpEF and HFrEF is that HFpEF (heart failure with preserved ejection fraction) takes place when the left ventricle fails to fill properly during diastolic phase while HFrEF (heart failure with reduced ejection fraction) takes place when the heart muscles fail to squeeze properly to pump an adequate amount of oxygen-rich blood […]
Difference Between Tonofibrils and Tonofilaments
The key difference between tonofibrils and tonofilaments is that tonofibrils are cytoplasmic fibrils found in epithelial cells that converge at desmosomes and hemidesmosomes, providing a framework to the cell while tonofilaments are keratin intermediate filaments that combine as bundles to make tonofibrils. Intermediate filaments are cytoplasmic protein structures found in eukaryotic cells. These filaments are […]
Difference Between Interstitial and Appositional Growth
The key difference between interstitial and appositional growth is that interstitial growth is the longitudinal growth of bone which increases the length of the bone while appositional growth is the bone growth which increases the diameter of the bone. Bones can grow. They can increase in length as well as in diameter or thickness. Moreover, […]
Difference Between Collagen Elastin and Reticular Fibers
The key difference between collagen elastin and reticular fibers is that collagen fibers are the most abundant type of fibers in the extracellular matrix of connective tissues while elastin fibers are tiny fibers that can stretch and recoil and they are found in elastic tissues. Meanwhile, reticular fibers are highly branched fibers which form a […]
Difference Between Connective Tissue Proper and Specialized Connective Tissue
The key difference between connective tissue proper and specialized connective tissue is that connective tissue proper consists of loose connective tissue and dense connective tissue while specialized connective tissue consists of reticular connective tissue, adipose tissue, cartilage, bone, and blood. There are four basic types of tissues in the animal body. Connective tissue is one of these types and it is […]
Difference Between Keratinized and Nonkeratinized Epithelium
The key difference between keratinized and nonkeratinized epithelium is that keratinized epithelium is impervious to water while nonkeratinized epithelium is pervious to water. Based on the presence of keratin protein, there are two types of epithelia as keratinized epithelium and nonkeratinized epithelium. Keratinized epithelium forms the epidermis of land vertebrates. Nonkeratinized epithelium lines the buccal […]
Difference Between Muscularis Layer of Esophagus and Stomach
The key difference between muscularis layer of esophagus and stomach is that muscularis layer of the esophagus has two layers while muscularis layer of the stomach has three layers. Gastrointestinal tract or GI tract has four layers. They are mucosa, submucosa, muscularis and serosa. Each layer is composed of different tissues. They also fulfill different […]
Difference Between True and False Aneurysm
The key difference between true and false aneurysm is that a true aneurysm is an enlargement of all three layers of the wall of an artery while a false aneurysm or pseudoaneurysm is not an enlargement of any layers of the blood vessel wall. Aneurysm is the bulging of the wall of a blood vessel, […]
