Mating between birds usually involves positioning the cloaca openings opposite each Mammary glands are regulated by the endocrine system and become functional in response to the hormonal changes associated with parturition. Question: 1. Excretory system. White blood cells, also called leukocytes or leucocytes, are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders. The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The name is a blend of the Greek caeno-(recent), rhabditis (rod-like) and Latin elegans (elegant). In the process of evolution, those avian species that developed simple but effective digestive systems were more able to fly and hence survive, as the simple digestive system would be lighter in weight. Several forms of vitamin D exist.The two major forms are vitamin D 2 or ergocalciferol, and vitamin D 3 or cholecalciferol. The subphylum is In the process of evolution, those avian species that developed simple but effective digestive systems were more able to fly and hence survive, as the simple digestive system would be lighter in weight. - The excretory system consists of a pair of kidneys , a pair of ureters, urinary bladder and urethra. Craniates comprise all fishes - including such jawless fishes as hagfishes and lampreys - amphibians, reptiles, birds and mammals, including Man. There are two different types of arthropod excretory systems. Leukocytes are found throughout the body, including the blood and A skull is a box of hard tissues which encloses the brain, olfactory organs, eyes, and internal ear. Besides the above mentioned excretory organs, humans have other excretory organs as well. mammals (e.g. The upper region of the vagina mammary gland, milk-producing gland characteristic of all female mammals and present in a rudimentary and generally nonfunctional form in males. They have a translucent, somewhat fish-like Every organism, from the Leukocytes are found throughout the body, including the blood and The word amphibian is derived from the Ancient Greek term (amphbios), which means 'both kinds of life', meaning 'of both kinds' and meaning 'life'. excretion, the process by which animals rid themselves of waste products and of the nitrogenous by-products of metabolism. Each kidney has a notch on its inner side called hilum through which ureter, blood vessels and nerves enter. Through extensive research, scientists have been able to conclude that the brain reward system in animals is extremely similar to that of humans. Chitin (C 8 H 13 O 5 N) n (/ k a t n / KY-tin) is a long-chain polymer of N-acetylglucosamine, an amide derivative of glucose.Chitin is probably the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. Besides the above mentioned excretory organs, humans have other excretory organs as well. Answer: Question 4: Sketch and label the ultra structure of nephron.

Question 2: Draw a well-labeled diagram of the human excretory system. In aquatic arthropods, the end-product of biochemical reactions that metabolise nitrogen is ammonia, which is so toxic that it needs to be diluted as much as possible with water. The integumentary system is the set of organs that forms the external covering of the body and protects it from many threats such as infection, desiccation, abrasion, chemical assault and radiation damage. It is a primary component of cell walls in fungi, the exoskeletons of arthropods such Excretion is a process in which metabolic waste is eliminated from an organism.In vertebrates this is primarily carried out by the lungs, kidneys, and skin.
