![]() ![]() Histology Study of tissues Pathology Is the study of disease Glycogen Glycogen is a polysaccharide that is the principal storage form of glucose (Glc) in animal and human cells. Negative Ion - Occurs when an atom gains an electron (negative charge) it will have more electrons than protons. Positive Ion - Occurs when an atom loses an electron (negative charge) it has more protons than electrons. Ion an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. In turn, molecules combine to form organelles, the internal organs of a cell. The chemical level includes the tiniest building blocks of matter, atoms, which combine to form molecules, like water. Organism Chemical level is the simplest level within the structural hierarchy. ![]() Levels of Structural Hierarchy Chemical level Cytology Cytology is that branch of life science that deals with the study of cells in terms of structure, function and chemistry. In short, it is the human being (or organism) as a whole. It is the sum total of all structural levels working together. Organismal level The organismal level is the highest level of organization. Besides the cardiovascular system, the other organ systems of the body are the integumentary, skeletal, nervous, muscular, endocrine, respiratory, lymphatic, digestive, urinary, and reproductive systems. For instance, the heart and blood vessels work together and circulate blood throughout the body to provide oxygen and nutrients to cells. Organ system level One or more organs work in unison to accomplish a common purpose. Each tissue has a characteristic role within the human body which we will discuss later. The four basic tissue types in humans include epithelium, connective, muscle, and nervous tissue. A tissue must contain two different types of cells. Tissue level Tissues are groups of similar cells that have a common function. Each type of cells carries out a set of unique tasks within the human body. Individual cells may have some common functions but vary widely in size and shape. Cellular level the cellular level is made up of the smallest unit of living matter, the cell. They are often referred to as intestinal worms even though not all helminths reside in the intestines Organ an organ is a structure composed of at least two different tissue types that perform a specific function within the body. Helminths parasitic worms, are large multicellular organisms, which when mature can generally be seen with the naked eye. Autoimmune disorders A disease in which the body's immune system attacks healthy cells. Ex: Fetal alcohol syndrome Carcinogen a substance capable of causing cancer in living tissue. The classes of teratogens include radiation, maternal infections, chemicals, and drugs. Or a teratogen may halt the pregnancy outright. Teratogens may cause a birth defect in the child. Some specializations within each of these sciences follow: Gross (macroscopic) anatomy Teratogen Any agent that can disturb the development of an embryo or fetus. If you have any questions about this article or, in general, about the subatomic particles, ping us through the comments section, and we will get back to you as soon as possible.What is physiology is the study of the function of body parts and the body as a whole. We hope this detailed article on Subatomic particles is helpful to you. Learn About Fundamental Nuclear Particles Its mass is almost equal to that of a proton.Īns: Protons are the particles of an atom that have a positive charge on them. ![]() They are important because they are the building block of matter.Īns: Neutrons are the particles of an atom that has no charge on them, and it resides in the central part of the atom that is the nucleus. Why are the subatomic particles important?Īns: There are three subatomic particles-electrons, protons, and neutrons. Protons and neutrons are composite particles made of quarks. What are the subatomic particles made of?Īns: Electrons are fundamental particles, and they belong to the first generation of the lepton particle family. Electrons are negatively charged particles, protons are positively charged particles, and neutrons are neutrally charged particles. What are the three subatomic particles?Īns: There are three subatomic particles-electrons, protons and neutrons. – The subatomic particles are held within the atom by one of the four fundamental forces- gravity, electromagnetic force, strong force, and weak force. – Electrons have a negative charge, and protons have a positive charge, and neutrons have no charge. – There are three subatomic particles called electrons, protons and neutrons. – A subatomic particle is a particle smaller than an atom. What are the features of subatomic particles?Īns: Some of the features of subatomic particles are: ![]()
