What is the respiratory system's role in the body?
One of the least understood responsibilities of the respiratory system is to help regulate the body's pH balance. Carbon dioxide is made into carbonic acid, which the respiratory system can regulate through carbon dioxide levels. When a patient has a condition that affects the body's acidity, respiratory rate and depth can be a sign of the problem.
Why is the integumentary system unique?
The integumentary system is unique because it is the only single-organ system. Skin is both an organ and the entire organ system.

What is the human body made of?
The human body is made up of several organ systems that work together as one unit. In the pyramid of life that organizes all of the elements of life into categories, organ systems are nested between an organism and its organs. Organ systems are the groups of organs that are within an organism. Ten major organ systems of ...
What is the cardiovascular system?
The cardiovascular system is comprised of the heart , blood, and blood vessels. The beating of the heart drives the cardiac cycle which pumps blood throughout the body. The lymphatic system is a vascular network of tubules and ducts that collect, filter and return lymph to blood circulation.
What is the nervous system?
The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. The major structures of the nervous system include the brain , spinal cord, and nerves .
What is the function of the circulatory system?
The main function of the circulatory system is to transport nutrients and gasses to cells and tissues throughout the body. This is accomplished by the circulation of blood. Two components of this system are the cardiovascular and lymphatic systems.
What are the four types of tissues?
The four types of tissues are exemplified in nervous tissue, stratified squamous epithelial tissue, cardiac muscle tissue, and connective tissue in small intestine.
Why is muscle tissue important?
Muscle tissue is essential for keeping the body upright, allowing it to move, and even pumping blood and pushing food through the digestive tract.
What are the functions of the digestive system?
For example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system—is responsible for taking up oxygen and getting rid of carbon dioxide. The muscular and skeletal systems are crucial for movement; the reproductive system handles reproduction; and the excretory system gets rid of metabolic waste.
What are the organs of the human body made of?
From left to right: single muscle cell, multiple muscle cells together forming muscle tissue, organ made up of muscle tissue (bladder), and organ system made up of kidneys, ureter, bladder and urethra.
How is structure related to function?
At each level of organization—cells, tissues, organs, and organ systems—structure is closely related to function. For instance, the cells in the small intestine that absorb nutrients look very different from the muscle cells needed for body movement. The structure of the heart reflects its job of pumping blood throughout the body, while the structure of the lungs maximizes the efficiency with which they can take up oxygen and release carbon dioxide.
How do the respiratory system and circulatory system work together?
For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide. The lungs expel the carbon dioxide and bring in new oxygen-containing air. Only when both systems are working together can oxygen and carbon dioxide be successfully exchanged between cells and environment.
Which muscle cells do not have striations?
From left to right. Smooth muscle cells, skeletal muscle cells, and cardiac muscle cells. Smooth muscle cells do not have striations, while skeletal muscle cells do. Cardiac muscle cells have striations, but, unlike the multinucleate skeletal cells, they have only one nucleus. Cardiac muscle tissue also has intercalated discs, specialized regions running along the plasma membrane that join adjacent cardiac muscle cells and assist in passing an electrical impulse from cell to cell.
What are the organs of the immune system?
The organs of the immune system include skin and mucous membranes, and the organs of the lymphatic system too. The immune system of the human body is made up of entire organs and vessel systems like the lymph vessels, as well as individual cells and proteins. The organs of the immune system include skin and mucous membranes, ...
Why are tonsils important?
The tonsils are also part of the immune system. Because of their location at the throat and palate, they can stop germs entering the body through the mouth or the nose. The tonsils also contain a lot of white blood cells, which are responsible for killing germs. There are different types of tonsils: palatine tonsils, adenoids and the lingual tonsil. All of these tonsillar structures together are sometimes called Waldeyer's ring since they form a ring around the opening to the throat from the mouth and nose.
