The Respiratory System
The respiratory system is one of the bodies most important systems, the main goal of the respiratory system is to provide gas exchange so the inhaling of oxygen and the exhaling of carbon dioxide. In the health and social care setting the words “respiratory rate” or “resps” are often used, this simply means how many times a person breathes in a minute this can help to diagnose problems such as asthma and other breathing related illnesses.
Parts of the Respiratory System and what they do
Nose: the nose is a main part in the respiratory system as it is the main way in which gasses enter and exit the body. Your nose has two nostrils which lead to the nasal cavity the air passes through these …show more content…
These hormones can increase or decrease the heart rate. These chemicals are produced in response to acute stress such as fright and anger. These cause the heart to pump harder and the heart rate to increase. They also open airways into the lungs, increase blood flow to major muscle groups and enable the body to fight or run in a stressful situation. Noradrenalin is related to the sympathetic nervous system.
Islets if Langerhans in pancreas: this gland produces the hormones insulin and glucagon insulin helps to regulate the glucose level within the blood by reducing it while glucagon increases it.
Ovaries/ testes: the testes produce the hormone called testosterone which is responsible for the characteristics within males it also is needed to produce sperm. The ovaries produce hormones called oestrogen and progesterone, Oestrogen strengthens bones and has a protective effect on the heart, and progesterone causes the womb's lining to thicken ready for pregnancy. The ovaries also produce small amounts of testosterone.
The lymphatic system
Function: an alternative circulatory system it also plays a role in the immune …show more content…
These tubes have valves which prevent back flow of fluids. This fluid is moved by pressure caused by muscles squeezing other tissues and indirectly pressing on the lymph vessels. This caused fluid to move slowly compared to blood in the cardio vascular system.
Lymph nodes: areas of connective tissue located at various locations along the lymph along the lymph vessels (especially in the neck arm pits and groin). They are “holding areas” for white blood cells. During an infection, many white blood cells may gather there to form swollen glands.
Thymus: located in the upper chest below the neck. It is involved in making a type of white blood cells these are known as T lymphocyte. These will migrate through the lymph vessels to wait in the lymph nodes.
Spleen: located below the stomach it acts as a reservoir for blood.
The immune system
The function of the immune system is to fight infections and prevent diseases.
The major components of the immune system are: * Spleen * White blood cells; Lymphocytes, Granulocytes and Monocytes * Thymus gland * Lymphatic vessels and lymph nodes * Adenoids *
