The Body System

Posted on by

Body systems are an organized group of tissue that forms a particular function. These functions work with other systems in the body. Some of the main systems of the body are digestive, circulatory, nervous, respiratory and muscular.

These functions work with other systems in the body. Some of the main systems of the body are digestive, circulatory, nervous, respiratory and muscular. Understanding these systems helps people know how the body functions and why the health of each of them is important for overall quality of life.

Muscular system: Enables the body to move using muscles. Nervous system: Collects and processes information from the senses via nerves and the brain and tells the muscles to contract to cause physical actions. Renal system and Urinary system The system where the kidneys filter blood to produce urine.

System Of The Body

Posted on by

Definition of Body Systems We can define body systems as groups of organs and tissues that work together to perform important jobs for the body. There are some organs in our body which are part of more than one body system as they serve more than one function. Apart from these, other organs and tissues serve only one purpose in the body system.

The main systems of the human body are:
Circulatory system :
Circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away.
Keeps the body’s temperature in a safe range.
Digestive system and Excretory system :
More items…

The highest level of body organization, then, is that of the organ system. The body includes nine major organ systems, each composed of various organs and tissues that work together as a functional unit. The chief constituents and prime functions of each system are summarized below.

Vascular System Of The Human Body

Posted on by

What is the Vascular System? The human body has two circulatory systems–the cardiovascular (vascular) system and the lymphatic system. The center of our attention here will be on the vascular system. So, just what is the vascular system?

What is the vascular system? 1 Arteries. . These are blood vessels that carry oxygenated blood away from the heart to the body. 2 Veins. . These are blood vessels that carry blood from the body back into the heart. 3 Capillaries. . These are tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body. More …

Simply put, the vascular system is a system of vessels with a vessel being defined as a hollow tube for carrying something. Blood vessels, therefore, are hollow tubes for carrying blood and are located throughout your body. There are three varieties of blood vessels: Arteries that carry blood away from the heart.

Lymph very closely resembles the plasma found in the veins: it is a mixture of about 90% water and 10% solutes such as proteins, cellular waste products, dissolved gases, and hormones. Lymph may also contain bacterial cells that are picked up from diseased tissues and the white blood cells that fight these pathogens.

Lymph nodes, lymph, and lymphatic vessels comprise the lymphatic system of the body. Lymph nodes filter lymph, a clear, sticky fluid that bathes body cells and collects waste products and debris. Lymph also carries white blood cells, which are responsible for protecting the body against viruses and bacteria and may trap cancer cells.

Transport of Fatty Acids. Another major function of the lymphatic system is the transportation of fatty acids from the digestive system. The digestive system breaks large macromolecules of carbohydrates, proteins, and lipids into smaller nutrients that can be absorbed through the villi of the intestinal wall.

Anatomy of the Urinary System How does the urinary system work? The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.

[edit on Wikidata] The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra.

The urinary tract is the body’s drainage system for the eventual removal of urine. The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein.

Spinal nerves are the major nerves of the body. A total of 31 pairs of spinal nerves control motor, sensory, and other functions. These nerves are located at the cervical, thoracic, lumbar, sacral, and coccygeal levels.

Spine and Nerves. Many nerves of the peripheral nervous system, which transport signals to and from specific parts of the body, meet the spinal cord at the vertebral column. Other roles for the vertebrae include helping support the body’s weight and providing an anchor for the ribs. The typical adult has 33 total vertebrae,…

The spinal cord does not run through the lumbar spine (lower back). After the spinal cord stops in the lower thoracic spine, the nerve roots from the lumbar and sacral levels come off the bottom of the cord like a “horse’s tail” (named the cauda equina) and exit the spine.

It’s a single layer of endothelium cells and some connective tissue. This layer sometimes contains one-way valves, especially in the veins of your arms and legs. These valves prevent blood from flowing backward. Veins are often categorized based on their location and any unique features or functions.

The pancreatic veins ( vv. pancreaticæ) consist of several small vessels which drain the body and tail of the pancreas, and open into the trunk of the lienal vein. The inferior mesenteric vein ( v. mesenterica inferior) returns blood from the rectum and the sigmoid, and descending parts of the colon.

The low pressure venous system needs the contraction of muscles to return the blood to the heart. There are four major types of veins. Examples include pulmonary and systemic veins as well as superficial and deep veins. Pulmonary veins carry oxygenated blood to the heart’s left atrium from the lungs,…

The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands,…

Nervous System. The nervous system has two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS ). The central system is the primary command center for the body, and is comprised of the brain and spinal cord. The peripheral nervous system consists of a network of nerves that connects the rest of the body to the CNS.

Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 8.2).

What Is The Female Reproductive System

Posted on by

The female reproductive system is made up of the internal and external sex organs that function in reproduction of new offspring.

Both male and female reproductive systems have internal and external structures. Reproductive organs are considered to be either primary or secondary organs based on their role. The primary reproductive organs of either system are called gonads (ovaries and testes) and these are responsible for gamete (sperm and egg cell) and hormone production.

The primary function of the reproductive system is to produce male and female sex cells and to ensure the growth and development of offspring. The reproductive system is comprised of male and female reproductive organs and structures.

Spinal nerves are the major nerves of the body. A total of 31 pairs of spinal nerves control motor, sensory, and other functions. These nerves are located at the cervical, thoracic, lumbar, sacral, and coccygeal levels.

Motor messages to the spinal nerves originate in the brain. The motor strip (homunculus) in the brain initiates a command for muscle control. This command is sent to the spine through nerve impulses and then travels through the motor root to the spinal nerve.

These are muscle movement, sensation, and autonomic functions (control of internal organs). Because their function is so well understood, when a particular spinal nerve becomes impaired, the resulting deficit often pinpoints which spinal nerve or nerves are affected. Motor messages to the spinal nerves originate in the brain.
