Laboratory report investigating the equine respiratory and cardiovascular systems Introduction The respiratory and cardiovascular systems of the horse work together to transport oxygen around the body and play an essential part in providing the horse with its increased need for oxygen during exercise. They allow the musculoskeletal system to use energy to facilitate motion. The cardiovascular system comprises the heart‚ blood vessels and blood. The heart pumps blood around the body

Effects of Smoking on Respiratory System Effects of Smoking on Respiratory System Every day‚ millions of people light up a cigarette and smoke. Some have just started smoking‚ while others have smoked their whole lives. Most likely‚ once you start smoking‚ you won’t be able to stop. It will be nearly impossible and if possible‚ it will not be easy. When people start smoking‚ they don’t really think about the harm that they are doing to themselves with every cigarette. Some don’t know how bad

Respiratory system: Minute ventilation is the quantity of oxygen which is taken in by your lungs per minute. When we exercise there is a higher oxygen intake per minute due to a higher breathing rate‚ we will also need more oxygenated blood cells to go round to the muscles in use to help try and prevent muscular injuries. The reason why when minute ventilation increases is positive to an athlete is because there is a higher intake of oxygen and nutrients needed. This will mean that the athlete

OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the respiratory system through

The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

So I decided to write it out. Here is my own journey in a seventh grade student that inhales that you will never experience again. It all started when a seventh grade student inhaled deeply in a Science Classroom. They were studying the Respiratory System in a human body. The teacher said to inhale and exhale deeply. So the student inhales and I decided to enter his nose with other molecules of oxygen to have a unique experience. After being smooched to enter his narrow nose‚ I saw several short

Respiratory General Questions 1. What is the function of the epiglottis? a. The main function of the epiglottis is to prevent food and other particles from gaining entry into the trachea and other airways. 2. Do you see any anatomical reason why the right lung has more lobes than the left lung - and is subsequently larger and heavier? a. The right lung may be larger and heavier because it has more room to develop as such. The heart is roughly centered in the chest cavity; however‚ it is slightly

TUTORIAL 2: RESPIRATORY SYSTEM OBJECTIVE QUESTION 1) High-flying birds are able to obtain enough oxygen even when the air is very thin because A) they have more efficient lungs than other vertebrates. B) they have reduced amounts of hemoglobin in their blood. C) their mitochondria are more efficient than those of other vertebrates. D) their heart can increase or decrease in size as altitude changes. E) they are able to store oxygen in oxygen chambers within muscle cells. 2) If you were to move from

objective of this report is to critically explain the physiological effects of exercise on the human respiratory system and cardiovascular system. To begin with‚ I will explain the two systems‚ their specific functions and how they inter-relate. I will then go on to analyse the effects of exercise on the two systems by looking at the way in which the body deals with an increased workload‚ and any health issues that may affect this. Cardiovascular system This system is responsible for pumping blood and
