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

Classification The crayfish falls within the kingdom - anamalia‚ phylum - Arthropoda‚ Class - Crustacea‚ Order -Decapoda ‚ and family - Cambaridae. Habitat Crayfish like to be where it’s dark and cool‚ and during much of the daylight they will be found by them selves‚ under a rock or vegetation‚ waiting for dark‚ when they come out to forage for food. This is highly variable‚ ranging from deep holes to sluggish streams. A suitable habitat is medium-sized streams containing riffles and rocky pools

Acids and Bases can cause pH changes---denature proteins • Normal pH of body fluids is 7.40 • Alkalosis (alkalemia) – arterial blood pH rises above 7.45 • Acidosis (acidemia) – arterial pH drops below 7.35 • Acidosis: – too much acid – Too little base • Alkalosis – Too much base – Too little acid Compensation for deviation • Lungs (only if not a respiratory problem) – If too much acid (low pH)—respiratory system will ventilate more (remove CO2) and this will raise pH back toward set point – If too

Differentiate Between Acidosis and Alkalosis Instructions 1. * 1 First differentiate between the respiratory and metabolic. The respiratory one has to do with breathing in and out (that is ventilation) while the metabolic has to do with processes inside the body. * 2 Know what each one is: Respiratory Respiratory acidosis happens when a person is hypoventilating. In this case their respiration is depressed and so they are retaining carbon dioxide leading to acidosis. This could be

Premium PH Carbon dioxide
Assignment Anatomy & Physiology II Respiratory acidosis is a condition that occurs when the lungs cannot remove all the carbon dioxide the body produces. This causes body fluids‚ especially the blood‚ to become too acidic. Chronic respiratory acidosis occurs over a long period of time‚ this leads to a stable situation‚ because the kidneys increase body chemicals‚ such as bicarbonate‚ that help restore the body’s acid-base balance. Acute respiratory acidosis is a condition in which carbon dioxide

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise‚ exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these‚ also the participants’ strengths and areas where they can improve on. - Effect of exercise on the musculoskeletal system As Andre began to exercise‚ this had an effect
