Function of the Endocrine System

  • The endocrine system produces hormones and chemical substances that regulate activity of cells & organs. The hormones help regulate growth, sexual development, & your metabolism.


Is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. For an organism to function normally and effectively, it is necessary that the biochemical processes of its tissues operate smoothly and conjointly in a stable setting. The endocrine system provides an essential mechanism called homeostasis that integrates body activities and at the same time ensures that the composition of the body fluids bathing the constituent cells remains constant.

Negative feedback

The control of blood sugar by insulin is another good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change . In turn, the pancreas secretes insulin into the blood effectively lowering blood sugar levels. Once blood sugar levels reach homeostasis, the pancreas stops releasing insulin.

Type 1 Diabetes

chronic condition in which the pancreas produces little or no insulin, a hormone needed to allow sugar to enter cells to produce energy.

Type 2 Diabetes

chronic condition that affects the way your body metabolizes sugar, your body's important source of fuel.

Skeletal System

Function of the Skeletal System

  • The function of the skeletal system is for support, movement, protection,calcium storage and endocrine regulation


  • Bones enable body movements by acting as levers and points of attachment for muscles.
  • Ligaments connect the bones
  • Muscle creates movement by contracting and pulling on our bones
  • Tendons connect muscle to bone
  • Nerves motor neurons provides the stimulus for muscle movement and co-ordinates sets of antagonistic muscles


  • Bone cancer that is most common in teens and young adults. Treatment involves surgery, chemotherapy or radiation.


  • a progressive disease in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leukocytes. These suppress the production of normal blood cells, leading to anemia and other symptoms.

Muscular System

Function of the Muscular System

  • The function of the muscular system is movement, and maintain posture and body position

muscular dystrophy

  • a hereditary disease characterized by progressive wasting of the muscles.

Nervous System

Functions of the nervous system

  • The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body's internal and external conditions.


  • A disorder in which nerve cell activity in the brain is disturbed, causing seizure

Alzheimer's disease

  • A progressive disease that destroys memory and other important mental functions

Reproductive System

Function of the Reproductive System

  • The purpose of the organs of the male reproductive system is to perform the following functions: To produce, maintain, and transport sperm and semen to discharge sperm within the female reproductive tract during sex.


  • the process in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.


  • is the creation of an ovum. It is the female form of gametogenesis; the male equivalent is spermatogenesis. It involves the development of the various stages of the immature ovum.


  • A disorder in which tissue that normally lines the uterus grows outside the uterus

Benign prostatic hyperplasia

  • Age-associated prostate gland enlargement that can cause urination difficulty
