Autonomic nervous system The autonomic nervous system (ANS or visceral nervous system) is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness‚ and controls visceral functions. The ANS affects heart rate‚ digestion‚ respiration rate‚ salivation‚ perspiration‚ diameter of the pupils‚ micturition (urination)‚ and sexual arousal. Whereas most of its actions are involuntary‚ some‚ such as breathing‚ work in tandem with the conscious

The Lymphatic System And Immunity The cells‚ tissues‚ and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens‚ or disease-causing organisms. Acts against environment hazards‚ various pathogens‚ and internal threats. Lymphocytes (primary cell) are vital to or overcoming infection and disease. Lymphocytes respond to invading pathogens‚ abnormal body cells‚ and foreign proteins. They act to eliminate these threats or render them harmless

RESPIRATORY SYSTEM Respiration (processes) 1. Ventilation and breathing‚ which is the movement of air into and out of the lungs 2. Exchange of oxygen and carbon dioxide between the air in the lungs and the blood 3. Transport of oxygen and carbon dioxide between the blood and tissues 4.

LYMPHATIC SYSTEM * Carries fluid in one direction‚ from the tissues to the circulatory system. Functions of the Lymphatic System 1. Fluid Balance * Collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream. 2. Fat Absorption * Absorbs fats and other substance from the digestive tract through lymphatic vessels called lacteals located in the lining of the small intestine. * Fat enters the lacteals and pass through the lymphatic vessels

The endocrine system is one of our body systems that plays an important role in living. It comprises of many glands exerting hormones in maintaining the body’s internal environment also known as homeostasis. The endocrine system plays an important role in homeostasis because it maintains growth and development‚ maturation‚ reproduction‚ human behavior‚ metabolism‚ sexual function and controls functions of the tissues. It is partnered with the nervous system since the hypothalamus along with the pineal

The body systems The Musculoskeletal system consists of the bones‚ muscles‚ ligaments and tendons. It provides structural support for the entire body. The musculoskeletal system allows and controls movement. The Cardiovascular system is responsible for transporting and removing gaseous waste from the body. The cardiovascular system is made up of your heart‚ blood vessels (arteries‚ veins‚ capillaries) and blood. The four major functions of the cardiovascular system are: To transport nutrients‚

The digestive‚ respiratory and the cardiovascular system are all interrelated in order to make the human body work effectively and efficiently by working as an orchestra. The cardiovascular system and the respiratory will work together in order to perform the gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. This means oxygen (in) CO2 (out).

Roscoe’s Journey Through the Respiratory System By: Carmen Ventura Hi‚ my name is Roscoe. Let me tell you about my journey. Carmen Ventura KINE-1306 Professor Bustamante Roscoe’s Journey through the Respiratory System Hi my name is Roscoe and I am an oxygen cell. I was told by my grandfather Gene that I was a very important cell. He told me that when someone takes a breath they take in all types of molecules in the air including myself. My grandfather was a very wise man and whenever
