Earthworms are hermaphrodites since they can generate both sperm and eggs. Mating involves 2 earthworms inseminating each other where sperms are exchanged. The male and female sexual cavities are located near the clitellum. They connect the lower ends of their anteriors with heads positioned in reverse directions. Mucous secreted joins the openings with slime. Sperm is pushed into the longitudinal channels formed by the mucous. They reach the sperm receptacles of their partner, which then break apart. Laying of the eggs and fertilization follows ("Native Australian," 2006)
The circulatory system is constituted of the heart, blood and blood vessels. It is needed to distribute nutrition to different areas in the body and is of two types -- open and closed. An open circulatory system (used by earthworms) is the simpler of the two where the heart drives blood into open spaces. The organs and tissues in the body are soaked in blood which flows at a low pressure. The system lacks any major arteries or veins. A closed circulatory system is used by larger animals. It consists of two...
ANATOMY Anatomy: Special SensesPrompt 1The human body has two senses types: special and general. Special senses include various body organs to feel the surroundings, for example, balancing, seeing, tasting, and smell, whereas general senses are only related to touch (Miller, 2020). The sensory data that the brain receives is collected by the skin that touches the objects. The general senses encompass pain, pressure, vibration, and proprioception. For instance, if we
Menopause: A Short History From Human Anatomy and Physiology, Spence and Mason, 2nd Edition from 1983, comes this description of Menopause. At about age 50, the ovarian and menstrual cycles gradually become irregular. Ovulation fails to occur during many of the irregular cycles and in most women the cycles cease altogether over the next several months or at most, a few years. The cessation of the menstrual cycle is referred to as
Anatomy Major cavities of the body and their organs: Our body is made up of solid structures and many cavities. The organs are packed in these cavities and they fill these cavities. The major cavities in our body are: the ventral cavity, which is surrounded by the rib cage and the abdominal musculature and dorsal cavity, which is surrounded by the bones of the skull and vertebral column. (Introduction / Terminology) Significance and

). These complications will be discussed in the discussion section of this paper. Discussion Taking into account the physiological functioning of these bacteria on the human sensory and muscles muscle system it becomes clear that that this can be a serious threat to human health and, as discussed above, this disease can lead to death. Modern medicine has however created an antidote to the effects of this disease. Tetanus can be prevented
Human-Equipment Interface Technological transformations have brought widespread use of machines and tools to the work setting. Owing to this, such concepts as human-machine/equipment interfaces have become increasingly prominent. In its simplest form, human-machine interface (HMI) refers to the point or extent of interaction between a machine and its operator; taken literally, it is the area of the machine and that of the human that interact during the execution of a task.
