1. Explain how the respiratory and circulatory systems coordinate the supply and transport of oxygen to the cells and removal of carbon dioxide from the blood. (10 Marks) Paragraph 1: What happens in the respiratory system? Respiratory System: Coordinating the Supply and transport of Oxygen * Oxygen is inhaled through the nose or mouth * Travels down through the Pharynx * Travels down the Larynx * Reaches the lungs and goes through the Bronchi * Through the Bronchioles

Reproductive System What is it? The reproductive system is a collection of organs that work together for the purpose of producing a new life The major organs of the reproductive system include the external genitalia and internal organs‚ including gonads that produce gamete‚ which is a cell that fuses with another cell during conception in organisms that reproduce sexually. Substances such as fluids‚ hormones‚ and pheromones are also important to the effective functioning of the reproductive system What

Immune System The immune system is the body’s defense against infectious organisms and other invaders. Through a series of steps called the immune response‚ the immune system attacks organisms and substances that invade body systems and cause disease The main way that your skin protects you against disease is through acting much as armor does to knight. The skin creates an impermeable layer that separates your body’s internals from the disease causing bacteria and viruses outside of you. Of course

Human Science – CHAPTER 1 1. Which Organ system maintains a relatively slow-acting degree of control over most bodily functions? Endocrine System (hormones act in minutes to hours‚ in contrast to nerve impulses‚ which act in fractions of a second). 2. The esophagus and the trachea run side-by-side through the thorax. In which systems are these organs found? The esophagus belongs to the digestive system‚ and the trachea belongs to the respiratory system. (The esophagus carries food to the stomach

The Main Body Systems 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.

Fish: Fish Niche - Fishes ecological niches that work in with their respiratory systems and gas exchange posess live in water eg. sea‚ rivers‚ streams and ponds. Fish such as cod live near the sea floor with competitors such as red cod‚ spotty and kahawai challenge them. There are predators such as dolphins‚ sharks and also people. Their gas exchange system has to be efficient for them to be able to compete with those fish and escape from predators. Fish live in an acquatic environment. Water

When the coffee is finished‚ our coffee maker’s beeping creates pressure changes‚ which move away from the machine and radiate to the individual’s location across the room. The waves reach the outer ear‚ which contains structures known as the pinnae‚ angled such that sound waves bounce off them and resonate. They enter the auditory canal after being significantly amplified before reaching the tympanic membrane. The waves strike the membrane and cause it to vibrate‚ which subsequently transmits them

It will describe the effect of COPD on patient’s lives‚ identifying the clinical presentation and discuss the significance of an acute exacerbation of COPD. This assignment will examine the guidelines and research surrounding COPD‚ particularly focusing on the use of non-invasive positive pressure ventilation (NPPV) in patients with respiratory failure precipitated by

The cardiovascular system which impacts deeply on human consciousness. The heart and the body’s blood-transporting network of arteries‚ veins‚ and smaller vessels form the circulatory or cardiovascular system. As blood is continuously pumped out from the heart and around the system in two circuits‚ it carries oxygen and vital nutrients to all parts of the body and removes harmful waste products from tissues.
