Structure of Gaseous Exchange Surfaces in Humans‚ Fish‚ Insects and Frogs Gaseous Exchange is a biological process where oxygen diffuses into the body or bloodstream and carbon dioxide diffuses out of the body or blood stream. This process is different for Humans‚ Fish. Frogs and Insects. Humans: In humans the gas exchange system is known as the Respiratory system. The respiratory surface is the Alveoli located on Bronchial tubes inside of the lungs. The average human adult has about 600 million

Gaseous exchange and transport Movement of chemicals in plants and animals -Chemicals that are being moved into the body‚ within the body or out of the body are gases‚ this movement is known as gaseous exchange. -The gases being moved in our out of the body need to move across the surface area of the body‚ in most cases a special surface area has been developed. -The surface that the gases cross is called the respiratory surface and the gases move across this surface by the process of diffusion

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

Gas Exchange All living organisms respire and they need energy to carry out their life processes in order for organisms to survive and produce. The gases involved in cellular respiration is oxygen and carbon dioxide. The process of cellular respiration is releasing energy from sugars using oxygen and the product is carbon dioxide and water and in the process‚ ATP is made that can then be used for cellular work. Oxygen is needed to be absorbed from the environment and into the organism’s blood so

RESPIRATORY PIGMENTS Colored‚ metal-containing proteins that combine reversibly with oxygen‚ found in the body fluids or tissues of multi-cellular invertebrate animals and microorganisms. The role of these pigments is primarily to aid in the transport of molecular oxygen. Thus they are distinguished from respiratory enzymes‚ which are concerned with the metabolic consumption of oxygen. Four distinctly colored groups of respiratory pigments exist among invertebrates: hemoglobins (purple‚ become orange-red

organisms adapted for efficient gas exchange? [25 marks] Many organisms have different features which enable them to survive and carry out gas exchange effectively. Single-celled organisms‚ such as bacteria and protozoa‚ are in constant contact with their external environment. For them‚ gas exchange occurs by diffusion across their membranes. Even in simple multicellular organisms‚ such as green algae‚ their cells may be close to the environment‚ and gas exchange can occur easily. In larger organisms

Done by: Instructor: Introduction Respiration is the number of processes which leads to the oxidation of organic compounds to produce the energy. There are several types of respiration‚ and one of them is aerobic. During the aerobic respiration‚ human uses the oxygen from atmosphere and produce carbon dioxide. A cardiorespiratory system which includes lungs‚ heart‚ blood vessels and others is responsible for all the processes linked to the respiration and controlled by the nervous system. During
