Lab Report Gaseous Exchange
Humans, performs gas exchange in order to transport gas, nutrients and waste throughout the body. Respiratory system and Circulatory are responsible to carry out the gas exchange. The Respiratory system is composed of nose, larynx, pharynx, trachea, bronchi, bronchioles, pleura, alveoli and diaphragm. The Circulatory system consists of the heart, blood vessels, arteries, arterioles, veins, venules, capillaries and blood. In this lab, we will only focus on the circulatory system.
The heart is the main component of the circulatory system because it is responsible for supplying oxygen-rich blood and nutrients to the tissues, removing wastes and carrying out the carbon dioxide outside the body. The heart has four chambers, two uppers chambers: the atria and two lower chambers: the ventricles. The atria are separated by a septum into the left atrium and the right atrium. The right atrium receives poor oxygenated blood returning to the heart from the vena calvae. The blood coming from the pulmonary circulation returned to the heart via the left atrium. The right ventricle receives blood from the right atrium and pumps into the pulmonary circulation to the lungs. The left ventricle receives blood coming from …show more content…
From the data gathered, our hypothesis came out to be that men will have a higher heart rate and blood pressure compared to women at rest and after exercising. The purpose of the report was to determine the relationship between gender and the cardiovascular activity of the individuals being texted. How exercising affects, the heart rate and blood pressure? What role does gender play in the blood pressure and heart rate? What other variables might influence the cardiovascular activity? To answer those questions, we will use the heart rate, the systolic and the diastolic pressure of students of the lab class at rest and after 15 seconds/ 30 seconds of step

    Bio 202 Exam 1: Summary

    The cardiovascular system consists of : heart (심장), and vessels (혈관), arteries (동맥), capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs, alveolar capillaries, and pulmonary veins leading from the lungs to the left atrium. 2. Carries the deoxygenated blood away from the heart to the lungs, and there by it brings the oxygen containing blood from lungs to the heart. Systemic Circuit : carrying blood from the heart to the rest of body 1. The systemic circuit includes the aorta (대동맥) and its branches leading to all body tissues as well as the system of veins returning blood to the right atrium. 2. Carries the oxygenated blood from the heart to the body, and also brings back the deoxygenated blood from the body to the heart. Structure of the Heart A. Size and Location of the Heart 1. The heart lies in the mediastinum under the sternum; its apex extends to the fifth intercostal space. 2. Approximately the size of the fist (주먹) 3. Location - Superior surface of diaphragm - Left of the midline - Anterior to the vertebral column, posterior to the sternum Coverings of the Heart 1. The pericardium(심장막) which encloses the heart. - Protects and anchors the heart - Prevents overfilling of the heart with blood - Allows for the heart to work in a relatively friction-free environment 2. It is made of two layers: I. The outer, tough connective tissue fibrous pericardium II. visceral pericardium (epicardium; 외심막) that surrounds the heart. 3. At the base of the heart, the visceral pericardium folds back to become the parietal pericardium that lines the fibrous pericardium. 4. Between the parietal and visceral pericardia is a potential space (pericardial cavity) filled…

    The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…

    p4 explain the physiology of two named body systems in relation to metabolism

    The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…

    The primary function of the respiratory system is the exchange of gases. The respiratory system allows oxygen and carbon dioxide exchange, this is necessary to sustain life. During the process of breathing air is inhaled and carbon dioxide is exhaled, this change of gases occurs in the alveoli. The inhaled oxygen passes into the alveoli and then diffuses into arterial blood. The waste rich blood from the veins releases carbon dioxide into the alveoli which is released through exhaling.…

    How the cardiovascular and respiratory systems are linked chloes work

    Gas exchange is a process done via the respiratory system to allow oxygen into the body and for carbon dioxide to leave the body through the blood cells. Gas exchange occurs in the lungs by oxygen entering via the nasal cavity, then through the trachea into the bronchus and then goes into the bronchiole which contain alveoli which is where it takes place, by diffusion (from a high concentrated area – alveoli – to a low concentrated area – capillaries) between the alveoli and the – many – capillaries surrounding it. This shows how the cardiovascular and respiratory system are inter-related because without the cardiovascular system, there would be no gas exchange occurring and without gas exchange we wouldn’t be able to breathe due to no oxygen getting into the blood and carbon dioxide wouldn’t be able to leave the body.…

    Coronary Artery Bypass Lab Report

    There are two upper chambers of the heart and they are called the atria. These chambers obtain and collect the blood. The left atrium gathers the flow of oxygenated blood that goes back to the heart. The right atrium receives deoxygenated blood through the inferior and superior vena cava. The right side of the heart pumps the deoxygenated blood in the pulmonary veins around the lungs. The two inferior chambers of the heart are called ventricles. The ventricles pump blood beyond your heart to all parts of the body. In a healthy working heart the right atrium, pumps blood into the right ventricle. From the right ventricle, blood is pumped to your lungs throughout the pulmonary…

    The heart lies in the thoratic cavity, organs associated with the heart are inferiorly, the hearts apex rested on the tendon of the diaphragm, superiorly, the great blood vessels, posteriorly the oesophagus, trachea and the left and right bronchus, laterally, the lungs and anteriorly the sternum and ribs. (Waugh& Grant 2014). The heart provides a constant blood circulation action and the blood vessels provide a network for the blood flow. The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body, ( www.le.ac.uk) the right side of the heart pumps blood to the lungs (pulmonary circulation) and the left side receives oxygenated blood and supplies it to the rest of the body (systemic circulation). There are three types of blood vessel, arteries, capilleries and veins. Blood is pumped from the heart through the arteries at high pressure which could damage the tissue so it needs to go through the capillaires which are smaller low pressure blood vessels that are responsilbe for providing oxygen to the tissues, they also absord excess carbon dioxide and then deliver the blood into the veins which then supply the blood back to the heart. The heart generates its own electrical impulses, it does not rely on any other external mechanisn to make it beat. A normal heart rate is 60-80 times per minute, factors which can decrease or…
