Themuscular systemenables movement through the contraction ofmuscles. Humans have three types of muscles: heart muscle, smooth muscle, and skeletal muscles. Skeletal muscle is made up of thousands of cylindrical muscle fibers. The fibers are bound together by connective tissue that is made up of b...
Although the details may vary, all mammals, including humans, have the same ten organ systems in terms of function: the digestive, respiratory, circulatory, urinary, nervous, muscular, skeletal, reproductive, endocrine and integumentary. Digestive The purpose of this organ system is to convert the...

What is the largest organ in a frog? Where is most of the muscle weight found in humans? What is the main organ of the circulatory system? What body system is the heart in? What is the most common mineral in the human body?
In amphibians, the skin plays a special role in gas exchange to some extent. Although the intricacy of the reproductive organs varies depending on the species, all animals have them. The uterus and ovaries are among the female reproductive organs in humans or the human body and other mammals;...
133 An analogous situation occurs in humans.134 The whole surface glycocalyx has been shown to have important functions in protection, information exchange, docking and delivery of sperm contents.135 The transformation of mature spermatids into spermatozoa (termed spermiogenesis) takes place mainly during...
