Hormones are produced in the endocrine glands of animals. The pituitary gland and hypothalamus are the most important in regards to the regulation of growth and development. Know the different hormones of animals in this tutorial...
The human body is capable of regulating growth and energy balance through various feedback mechanisms. Get to know the events of absorptive and post-absorptive states. This tutorial also describes the endocrine and neural control of compounds such as insulin and glucagon. It also deals with the regulation of growth, heat loss, and heat gain. ..
Humans are capable of only one mode of reproduction, i.e. sexual reproduction. Haploid sex cells (gametes) are produced so that at fertilization a diploid zygote forms. This tutorial is an in-depth study guide regarding male and female reproductive physiology...
Hormones are chemical messengers produced by specialized glands and they were produced by switching on the genes designed to produce them. This tutorial looks at how genes control the production of hormones within the endocrine system of animals...
This tutorial elaborates on the physical development of humans, particularly from puberty to adulthood. Read this tutorial to know the specific physical changes that female and male bodies undergo as they turn into adults...
For human species to obviate extinction, reproductive mature adults should be producing viable offspring in order to continue the existence of the species and pass on genetic information from generation to generation. Read this tutorial to learn more about human reproduction and fertilization...
