Order the levels of organization in the human body from smallest to largest.
organism --> organ system --> organ --> tissue --> cell
cell --> tissue --> organism --> organ system --> organ
cell --> tissue --> organ --> organ system --> organism
(This is 7th grade science)
Answer:
cell, tissue, organ, organ system, organism
Explanation:
Alright! This will be a snap! All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules. Molecules can be small (for example, O2, oxygen gas, which has 2 atoms of the element O; CO2, carbon dioxide, which has 1 atom of C and 2 of O), medium (for example, C6H12O6, glucose, which has 6 atoms of C, 12 of H, and 6 of O); or large (for example molecules called proteins are made of hundreds of atoms of C, H, and O with other elements such as nitrogen (N). Molecules are the building blocks to all structures in the human body.
All living structures are made of cells, which are made of many different molecules. Cells are the smallest independent living thing in the human body. The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). All human cells are made of a cell membrane (thin outer layer) that encloses a jelly-like cellular fluid containing tiny organ-like
structures called organelles. There are many types of organelles, each with a particular function (for example, organelles called mitochondrion provides energy to a cell). Different types of cells contain different amounts and types of organelles, depending on their function, (for example muscle cells use a lot of energy and therefore have many mitochondria while skin cells do not and have few mitochondria).
As in other multicellular organisms, cells in the human body are organized into tissues. A tissue is a group of similar cells that work together to perform a specific function. There are four main tissue types in humans (muscular, epithelial, nervous and connective). An organ is an identifiable structure of the body composed of two or more tissues types (for example, the stomach contains muscular tissue made of muscle cells, which allows it to change its shape, epithelial tissue which lines both the inner and outer surface of the
stomach, nervous tissue which sends and receives signals to and from the stomach and the central nervous system, and connective tissue which binds everything together). Organs often perform a specific physiological function (for example, the stomach helps digest food). An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste). The most complex level of organization, the human organism is composed of many organ systems that work together to perform the functions of an
independent individual.

Which system allows for the continuation of the species?
Answer:
the reproductive system
There are various organ systems that perform various activities and functions in an organism. The reproductive system allows for the continuation of the species.
What is the reproductive system?The reproductive system is one of the organ systems that undergo a process of fertilization to produce offspring. It has been the biological system that has various anatomical organs that produce the gametes of the fertilization process.
They are involved in the production of sperm and eggs that gets transported and fertilized to form an embryo that is nurtured by the females and develops into offspring. This is the process that is involved in continuity of the life by producing species of the same type.
Therefore, the reproductive system allows for the continuation of living beings.

In full and complete sentences answer what are the different types of muscles?
What are their functions?
Give an example of where each is located.
Answer:
3. Cardiac muscle cells - are used to help the heart beat and pump blood.
2. Smooth muscle cells- are used in the digestion of food.
1. Skeletal muscle cells- are involved in movements of the skeleton (bones).
Explanation:
There are three types of muscle cells - skeletal, cardiac and smooth.
The skeletal muscle cells are the ones that form the muscle and help to contract and relax. The muscles for movement to take place. these are voluntary muscles and appears striated when viewed under a microscope.
The cardiac muscles are the ones that are found in the heart and are involved in the contraction of the heart for pumping the blood and making the heartbeat. These are involuntary muscles and appear striated under the microscope.
The smooth muscles are the ones that are used to control the involuntary movements in the body except for the heart. Since digestion involves involuntary muscles these are located in the walls of the digestive organs such as stomach and intestine. These muscle cells are non-striated.

Answer: Smooth Muscles, Cardiac Muscle, and Cardiac muscle.
Explanation:
Smooth Muscles
Visceral muscle is found inside organs like the stomach, intestines, and blood vessels. Visceral muscles are the weakest of all the muscles. Their main function is to move substances through the organ. This type of muscle is also called plain, unstriped, non-striated, visceral, or involuntary muscles. Visceral muscles are also called involuntary muscles as they are controlled by the part of the brain which cannot be directly controlled by the conscious mind. Smooth muscles do not exhibit cross-striations under a microscope, being plain and smooth in form and their uniform appearance, when viewed under a microscope, has led to the term smooth muscle. The smooth muscle fiber is an elongated, spindle-shaped cell, with a single nucleus placed centrally; the myofibrils show longitudinal striations. They are supplied by autonomic nerves and are capable of sustained contraction, and, therefore, do not fatigue easily. They provide motor power for regulating the internal environment related to digestion, circulation, secretion, and excretion. These are less dependent on nervous control, being capable of contracting automatically, spontaneously, and often rhythmically. Muscles of the blood vessels, and the arrector pili or erector pili muscles of the skin are examples of smooth muscles.
Cardiac Muscle
This type of muscle, as the name suggests is found in the heart. It is intermediate in structure, being striated and at the same time involuntary. It is meant for automatic and rhythmic-contractions. These fibers have a single nucleus placed centrally which branches and anastomoses with the neighboring fibers at intercalated discs (apposed cell membranes). The cross-striations are less prominent than those in the skeletal muscle. It is responsible for pumping blood. It is unique as it stimulates itself to contract [autorhythmic or intrinsically controlled] by a pacemaker which is also made of cardiac muscle tissue. The cells of cardiac muscle tissue are striated—that is, they appear to have light and dark stripes when viewed under a light microscope. The arrangement of protein fibers inside the cells causes these light and dark bands. Striations indicate that a muscle cell is very strong, unlike visceral muscles. The cells of cardiac muscle are branched X or Y-shaped cells tightly connected by finger-like projections from two neighboring cells [called intercalated discs] that interlock and provide a strong bond between the cells. The branched structure and intercalated discs allow the cells to resist high blood pressures and the strain of continuous working. These features also help to spread electrochemical signals quickly from cell to cell so that the heart can beat as a unit.
Skeletal Muscles
Skeletal muscles are types of muscles that are most abundant and are found attached to the skeleton. They are also called striped, striated, somatic, or voluntary muscles. They exhibit cross-striations under the microscope and are considered to be the best-differentiated form of muscle. They are supplied by somatic (cerebrospinal) nerves, and, therefore, are under voluntary control, with certain exceptions. They respond quickly to stimuli, being capable of rapid contractions, and help in adjusting the individual to an external environment. They also get fatigued very easily. Each muscle fiber of skeletal muscle is a multinucleated cylindrical cell, containing groups of myofibrils. Myofibrils are made up of myofilaments of three types (myosin, actin, and tropomyosin). These are the actual contractile elements of the muscle. These are under the highest nervous control of the cerebral cortex. Examples of these types of muscles are muscles of limbs and body wall, and bronchial muscles are examples of skeletal muscles.
