We can elaborate by saying that anatomy is the detailed study of different body parts, their organization, and their interrelationship, but how these body parts and organs play their specific role in a coordinated manner is termed as physiology. An understanding of these terms is not only beneficial to health professionals and their career; instead, it helps us know about your own body and its wellness. Familiarity … [Read more...]
Difference Between Rods and Cones
Rods and Cones are the photoreceptors, useful in providing vision to the eyes. Rods provide vision during dim light or night also known as scotopic vision, whereas cones provide vision during day time or at bright light also known as photopic vision. Secondly, rods do not support the colour vision, but cones are capable of colour vision, with high spatial acuity — the level of the light where both the types of work, is called a mesopic vision. Eyes are one of the primary sense organs found … [Read more...]
Difference Between Oestrogen (Estrogen) and Progesterone

These are the types of steroids hormones and are categorized under two category which are corticosteroids and sex steroids. Among which the mineralocorticoids and glucocorticoids are the are the types corticosteroids, while oestrogen or estrogen, … [Read more...]
Difference Between Hibernation and Aestivation (Estivation)
The state of inactivity and a low metabolic process performed by the animals during the winters is known as Hibernation. It is also known as winter sleep. On the contrary, when animals take rest in shady and moist place during summer, it is called Aestivation or Estivation. Aestivation is also known as summer sleep. The importance of these sleep is mainly related to the conservation of energy of one's body, survival during the extremes temperature, scarcity of food and water, etc. These sleep … [Read more...]
Difference Between Oviparous and Viviparous Animals
Birds, insects, reptiles, amphibians, and fish falls under the category of oviparous, as they lay eggs and give rise to more of their kind, in order to increase their generation. While mammals like humans, cats, dogs, lions, tigers, etc are said as the viviparous, as they directly give birth to the young ones. Fertilization is the union of two nuclei, one is of paternal origin and the other is from the maternal origin which finally fuses to form an embryo. There are different patterns of … [Read more...]
Difference Between Amphibians and Reptiles
Amphibians are known to live dual lives, as they spend their half-life in water and remaining half on land, these also have porous skin which requires moisture. While Reptiles are the group of animals that live on land, breathe through lungs and lay eggs, they have scales on their body and function to retain moisture. So the essential difference lies in their life cycle and physical appearances. Despite this, these animals shared many similarities, and this is the reason that in earlier … [Read more...]
Difference Between Male and Female Reproductive System
The functional and most significant difference in the male and female reproductive system is that male reproductive system only produces sperms and delivers to the female reproductive system. On the other hand, the female reproductive system is designed to produce a baby and promote its development. Reproduction is the process of fusion of male and female gamete, to produce their species. While the organs of an individual body involved in this process, together known as the reproductive … [Read more...]
Difference Between Internal and External Fertilization
Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies. Internal fertilization is followed by mammals, birds, while external fertilization is supported by mostly aquatic animals and few amphibians. We all are aware of the word fertilization, which defines … [Read more...]
Difference Between Arteries and Veins
Arteries carry oxygenated blood away from the heart, these are the thick-walled muscular tube, while Veins carry deoxygenated blood towards the heart. Though both have the exception of the pulmonary artery and vein, as here the system get opposite and the pulmonary artery carries the deoxygenated blood, and pulmonary vein carries oxygenated blood. Among the two types of circulatory system - Open circulation and Closed circulation. In vertebrates, closed type of circulatory system is found, … [Read more...]
Difference Between Human Sperm and Ovum
Sperm is the male gamete, produced in the testis of a male, while Ovum is the female gamete, produced in the ovary of a female. Ovum, also known as egg cell and is said to be the largest cell in the female body. On the contrary Sperm cells is the smallest cell in the male body. Egg cell and sperm cells differ in many ways, which can be their origin, nature, composition, and purpose for existence. Though both play an important role at the time of human reproduction process, where the … [Read more...]
