Parasitic adaptation of Taenia

Taenia Parasitic adaptations Tapeworms live as internal parasites and they have to make several adjustments for the same. The following are few of the adaptations made by these tapeworms to make their life easy in their hosts. Presence of enzymatic resistant covering A hard covering called as tegument covers the body of these tape worms. Tegument is enzyme resistant and it protects all the internal organs from the digestive actions of the alkaline fluids of the host. On the other hand tegument is permeable to water and other nutrients. Absence of locomotory organelles This parasite lacks organs for locomotion. As there is no need for any locomotory organs both the adult and larval forms lack cilia or flagella. Osmotic pressure The osmotic pressure inside the body is higher than that of the surrounding host tissue or fluid. This helps the parasite to reside conveniently in the host body. Presence of hooks and suckers for attachment For the attachment purpose a scolex...

Animal physiology. Adaptation and Environment

GET Animal physiology. Adaptation and Environment Author(s): Knut Schmidt-Nielsen Description: This book is about animals and their problems. It is not only about how animals function, but about the problems of living and how animals solve them. It is also about aspects of physiology that I find particularly fascinating or interesting. The book is written for the student who wants to know what animals do and how they do it. The text deals with the familiar subjects of physiology: respiration, circulation, digestion, and soon. These subjects are treated in thirteen chapters, arranged according to major environmental features: oxygen, food and energy, temperature, and water. I consider this arrangement important, for there is no way to be a good physiologist, or a good biologist for that matter, without understanding how living organisms function in their environment. The book is elementary and the needed background is minimal. The first edition of Animal Physiology has been wi...
