Your body systems work together to keep you alive. An important function of your body systems is to supply your cells What's the difference between your.

New discoveries about how the body's systems function and work together continue understanding of the body's integrated working parts and organ systems has been in place for centuries. Relationship Between Lymphocytes & Nutrition.
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.
Because of their specialization, these different systems are dependent on each other. The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system—as well as all the other systems—need nutrients and must get rid of metabolic wastes.
All the systems of the body work together to keep an organism up and running. Overview of body organization All living organisms are made up of one or more cells. Unicellular organisms, like amoebas, consist of only a single cell.
Tissues, organs, & organ systems (article) | Khan Academy
Multicellular organisms, like people, are made up of many cells. Cells are considered the fundamental units of life. The cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task. Organs are structures made up of two or more tissues organized to carry out a particular function, and groups of organs with related functions make up the different organ systems.
From left to right: 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. Types of tissues As we saw above, every organ is made up of two or more tissues, groups of similar cells that work together to perform a specific task.
Humans—and other large multicellular animals—are made up of four basic tissue types: The four types of tissues are exemplified in nervous tissue, stratified squamous epithelial tissue, cardiac muscle tissue, and connective tissue in small intestine. For instance, the outer layer of your skin is an epithelial tissue, and so is the lining of your small intestine. Epithelial cells are polarized, meaning that they have a top and a bottom side.

The apical, top, side of an epithelial cell faces the inside of a cavity or the outside of a structure and is usually exposed to fluid or air. The basal, bottom, side faces the underlying cells.
For instance, the apical sides of intestinal cells have finger-like structures that increase surface area for absorbing nutrients. Image showing three cells lining the small intestine.
Each cell contains a nucleus and is surrounded by a plasma membrane.
The tops of the cells have microvilli that face the cavity from which substances will be absorbed. Often, the cells are joined by specialized junctions that hold them tightly together to reduce leaks. Connective tissue Connective tissue consists of cells suspended in an extracellular matrix. In most cases, the matrix is made up of protein fibers like collagen and fibrin in a solid, liquid, or jellylike ground substance. Connective tissue supports and, as the name suggests, connects other tissues.
Loose connective tissue, show below, is the most common type of connective tissue. It's found throughout your body, and it supports organs and blood vessels and links epithelial tissues to the muscles underneath.
Body Systems & How They Work Together
Dense, or fibrous, connective tissue is found in tendons and ligaments, which connect muscles to bones and bones to each other, respectively. Loose connective tissue is composed of loosely woven collagen and elastic fibers.
The fibers and other components of the connective tissue matrix are secreted by fibroblasts. Specialized forms of connective tissue include adipose tissue—body fat—bone, cartilage, and bloodin which the extracellular matrix is a liquid called plasma. Muscle tissue Muscle tissue is essential for keeping the body upright, allowing it to move, and even pumping blood and pushing food through the digestive tract. Muscle cells, often called muscle fibers, contain the proteins actin and myosin, which allow them to contract.
There are three main types of muscle: 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.
Skeletal muscle is attached to bones by tendons, and it allows you to consciously control your movements. For instance, the quads in your legs or biceps in your arms are skeletal muscle.

Cardiac muscle is found only in the walls of the heart. Like skeletal muscle, cardiac muscle is striated, or striped. But it's not under voluntary control, so—thankfully! The individual fibers are connected by structures called intercalated disks, which allow them to contract in sync. The pituitary is is considered a master gland, since it governs the release of hormones by other glands.
Unlike the nervous system, there is no physical "wiring" with neurons, however, and the hormones reach their target via the blood stream, where they exert their effect.
The endocrine and nervous system may work together on the same organ, and each may influence the actions of the other system. The endocrine system largely governs many processes related to reproduction and sexual maturity, as well.
The immune system is a network of cells, tissues and organs that work together to attack pathogens that try to invade your body. Bacteria, parasites and fungi that may cause infection meet a system of immune soldiers, including T-lymphocytes, macrophages and neutrophils. With time, the immune system's B-lymphocytes can produce antibodies against a new unknown invader.
The immune system also plays a role in detecting non-self markers on cells that may arise in cancer cells and due to organ transplants.
Stress, as perceived by the nervous system, can have a remarkable impact on the immune system and also the digestive system, which happens to be another major site of immune cell activity.
Integumentary and Nervous Systems The integumentary system, or skin, is the body's first line of defense. It regulates body temperature, protects underlying layers of tissue from sun damage and prevents pathogens from freely entering your body. The integumentary system is also home to millions of nerves that respond to touch, pressure and pain.
There are two interconnected nervous systems: The central nervous system includes the spinal cord and the brain, which gets the information from the body and sends out instructions. The peripheral nervous system includes all of the nerves and sends messages from the brain to the rest of the body.
The nervous system controls both voluntary and involuntary, automatic activities and bodily functions. Both the nervous system and endocrine system serve to integrate the body's various other systems, keeping things in synch. When the cardiovascular system is low on fluid, such as in severe dehydration, the skin loses its normal resiliency and can actually form a "tent" when pinched, instead of springing back into shape. Skeletal and Muscular Systems The system that provides your body's shape is the skeletal system, and it is made up of cartilage and bone.
There are bones in the human skeleton that provide a hard framework able to support the body and protect the organs that they surround.
