The Organ Systems of the Human Body The human body is made up of 11 organ systems. The Integumentary System‚ Skeletal System‚ Muscular System‚ Nervous System‚ Endocrine System‚ Circulatory System‚ Lymphatic System‚ Respiratory System‚ Urinary System‚ Digestive System‚ and Reproductive System for the male and female. Also‚ we have the Immune System which is an accumulation of cells rather than an organ system. Protection‚ support and movement are the main functions of the Integumentary system

a positive feedback loop moves a system further away from the target of equilibrium. It does this by amplifying the effects of a product or event and occurs when something needs to happen quickly. An example of this type of feedback loop in the endocrine system is occurs during childbirth. When labor begins. The baby’s head is pushed downwards‚ resulting in an increased pressure on the cervix. This stimulates receptor cells to send a chemical signal to the brain‚ allowing the release of oxytocin

1) What is the role of calcium ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting

Homeostatic mechanisms are controlled by two systems‚ the nervous system and endocrine system. The nervous system regulates homeostatic mechanisms by releasing nerve impulses in order to neutralize whatever change occurred. The endocrine system regulates homeostatic mechanisms by releasing hormones into the blood. When bodily changes take place‚ the nervous system tends to react and correct change more rapidly than endocrine system. Feedback systems are what maintain homeostasis. Feedback systems are

body to work accordingly and appropriately at the specific times required. The system within the body which assists to control and coordinate the functioning of all the systems is called the nervous system. The nervous system works alongside the endocrine system allowing communication and coordination between the many organs and systems within the human body. This allows them to function correctly‚ and have the ability to respond to stimuli when needed. The nervous system has two main systems within

The major part of the pancreas‚ called the exocrine pancreas‚ functions as an exocrine gland‚ secreting digestive enzymes into the gastrointestinal tract. Distributed through the pancreas are clusters of endocrine cells that secrete insulin‚ glucagon‚ and somastatin. These hormones all participate in regulating

ends in the pituitary stalk‚ a part of the pituitary gland. It forms the major portion of the ventral region of diencephalons‚ and oversees autonomic and metabolic processes. The hypothalamus is the connection between the nervous system and the endocrine system‚ creating this link by producing and secreting neurohormones that in turn stimulate the anterior pituitary gland to secrete hormones. The hypothalamus is central in the regulation of body temperature‚ hunger‚ thirst‚ and in the management

The chosen model of care is Essentials of Care (EOC). The EOC model is a framework that focuses on the essential components of patient centred care and seeks to support the development and ongoing evaluation of nursing and midwifery practice. The main purpose of the EOC model is to improve patient safety and outcomes by enabling nurses and midwives to emphasis on developing clinical environments that enhance patient care‚ teamwork and individual work satisfaction (NSW department of health 2009).

Given your symptoms‚ you suffered from severe hypothermia. You are suffering from this condition as you were exposed to cold temperatures for a sustained amount of time. The human body works to maintain homeostasis‚ which is where the internal temperature of the body is kept in narrow limits. The human body must be kept within a certain range of temperatures. If the temperature of the body goes outside of this range‚ there is a system in body called the negative feedback system‚ which is where the
