This is the level of the operation of atoms and molecules. Atoms are the smallest units of matter. At this level atoms combine to form molecules ; in turn. Level 2: Cellular cells. Organelles like plasma membrane, nucleus, ribosome, endosplasmic reticulum, and golgi body combine to form cells. Cells are the smallest units that can carry out all the essential functions of life Level 3: Tissue s A tissue is a group of similar cells that work together to carry out special functions.
The major human tissues are epithelium, connective tissue, muscular tissue, and nervous tissue. Major functions of tissues: Epithelium covers and lines surfaces. Connective tissue supports and protects softer tissues. Muscular tissue effects movement. Nervous tissue is responsible for internal communication and environmental awareness. Level 4: Organ s. An organ is a complex structure that comprises at two or more tissues. Organs are dedicated to carrying out specific functions.
Examples are heart pumps blood around circulatory system ; kidneys remove and excrete wastes from the blood ; brain responsible for consciousness and coordination of body's activities ; small intestine absorption of digested nutrients. Level 5: Organ System : The organ system comes next in the hierarchy. An organ system is a group of organs that work together for a common physiological purpose.
The main organ systems of the human body are integumentary, muscular, nervous, skin cardiovascular, skeletal, endocrine, lymphatic, reproductive, and digestive system.
Categories of immunological system, and urinary system are sometime used in the healthcare professions to complete this listing.

The subject can be a challenge in college but the payoff is well worth it. We will also review the needs and functional processes common to all living organisms.
Anatomy — studies the structure of body parts and their relationships to one another. Physiology — studies the function of body parts how they work and carry out tasks. For example, blood flows through the heart in one direction because the heart has built in valves that prevent backflow. Bones are strong and can support the body because they contain hard mineral deposits.
