Semen is a thick, yellowish white, glairy, opalescent, secretion having a characteristic odour known as seminal odor.It is also called seminal fluid, fluid that is ejaculated from the male reproductive tract and that contains sperm cells, which are capable of fertilizing the female eggs. Semen also contains other liquids, known as seminal plasma, which help […]

Chemical Control and Coordination
In the previous post, we read about Neural Control and Coordination.Let us now talk about chemical control and coordination. Since, the cellular functions need to be continuously regulated. This cellular regulation is carried out by another coordinating system. They use chemical messengers called hormones, which are released by endocrine glands. The endocrine glands release their […]
Neural Control and Coordination
We have studied that a number of physiological processes take place in the body of animals. Digestion, respiration, transportation, excretion, movement and locomotion are major physiological processes occurring in the body. Now, you all must be curious to know that how these complex processes work in a controlled and regulated manner i.e about neural control […]
Human Skeletal System
Previous post was all about locomotion and movement. In this post we will study at length about the Human Skeletal System. Skeletal system is a system of external and internal, living or dead, hardened structures which forms the supportive, protective and jointed framework of the body. Hard or flexible, internal and external structures of the […]
Locomotion and movement
In our last post we gave you an insight about Human Respiratory System. In this post, I’d like to take you through the process of locomotion and movement. Movement is change in posture or position. It is an essential and significant feature of living organisms. In many organisms’ different structures such as cilia, flagella, limbs […]
Human Respiratory System
In our last post, we studied about human circulatory system. Hope you have understood it well, if you have any doubts fee free to post your query in the comment section below. In this post we will study about human respiratory system. The process of exchange of O2 from the atmosphere with CO2 produced by […]
