Define and describe the six levels of organization of the body and explain the eleven major organs systems in the body.Define and describe the six levels of organization of the body and explain the eleven major organ systems in the body?

Expert Solution

The human beings body is organized at different levels, starting from cell and ends to entire organism. The cells are formed to tissues, tissues formed to organs, organs organized to organ systems( muscular and skeletal systems).

The six level of organisation of the body are ,

Chemical
cellular
Tissue
organ
System
Organismal

The eleven major organ systems in the human body are,

Skeletal
Integumentary
Muscular
Nervous
Endocrine
Cardiovascular
Lymphatic
Respiratory
Digestive
Urinary
Reproductive systems.

Skeletal

The skeletal system consists of bones, joints and teeth. The bones of the skeletal system are connected by tendons, ligaments, and cartilage. The functions of the skeletal system include supporting the body and providing shape to the body.

Integumentary

The organs of the integumentary system include the skin, hair, and nails.

Muscular system

The muscular system consists of three different types of muscles. They are skeletal muscles, smooth muscles and cardiac muscles. The skeletal muscle are attached to bones by tendons and allow for voluntary movements of the body. The smooth muscle control the involuntary movements of internal organs. Cardiac muscle tissues control the involuntary beating of the heart

Nervous system

The nervous system includes the brain and spinal cord.
The nervous system controls both voluntary and involuntary responses of the human organism. And also have the capability to detect and processes sensory information.

Endocrine system

The endocrine system is made up of glands that secrete hormones into the blood, which then carries hormones throughout the body.

Cardiovascular system

The cardiovascular systemincludes the heart, blood and three types of blood vessels (arteries, veins, and capillaries).The heart pumps blood, which travels through the blood vessels and their main function is the transport of oxygen with the blood through out the body.

Lymphatic system

The lymphatic system the immune system which consists of a network of lymph vessels and ducts that collect excess fluid from extracellular spaces in tissues and transport the fluid to the bloodstream.

Digestive system

 The digestive system consists of several main organs which includes the mouth, esophagus, stomach, and small and large intestines . Food moves through gastro intestinal tract,and it is digested. Its nutrients are then absorbed, and its waste products are excreted.

Urinary system

 The urinary system is part of the excretory system, which removes wastes from the body. The urinary system includes the pair of kidneys, which filter excess water and a waste product (called urea) from the blood and form urine.

Reproductive systems

The reproductive system is the only body system that differs between males and females. Both male and female reproductive systems produce specific sex hormones (testosterone in males, estrogen in females) and gametes (sperm in males, eggs in females).
