Circulatory Pathway 1 Arteries Capillaries Veins Thick-walled blood vessels that contain muscle tissue Muscles contract in a rhythm (pulse) Carry blood away from the heart Capillaries Microscopic blood vessels whose cell walls are only one cell thickness Place where the exchanges take place Veins Thin-walled blood vessels that lack muscular tissues Contain valves that prevent the backflow of blood Carry blood toward the heart Thursday, November 15, 2018Thursday, November 15, 2018
Circulatory Pathway II Heart Muscle located in an area between the lungs Divided into four parts 2 atriums Receive blood into the heart 2 ventricles Pump blood from the heart Valves In place to prevent the back flow of blood Thursday, November 15, 2018Thursday, November 15, 2018

Pulmonary Veins/Arteries Pulmonary Arteries Are the only arteries to transport de-oxygenated blood from the heart {going towards the lungs} Pulmonary Veins Are the only veins to transport oxygenated blood towards the heart {coming from the lungs} Thursday, November 15, 2018Thursday, November 15, 2018
Circulatory Pathway III Inferior & Superior Vena Cavas Right Atrium Right Ventricle Pulmonary Artery Carry blood towards the lungs Lungs Pulmonary Vein Carry blood from the lungs Left Atrium Left Ventricle Aorta Arteries Capillaries Veins Thursday, November 15, 2018Thursday, November 15, 2018

The Immune System III Third Line of Defense Consists of mechanisms and agents that target specific antigens Antigen A foreign macromolecule that DOES NOT belong in the host organism Antibodies Proteins that bind to antigens Found on B Cells Thursday, November 15, 2018Thursday, November 15, 2018
Respiratory System Thursday, November 15, 2018Thursday, November 15, 2018
Respiratory System I Deliver air to the lungs Breathing Inspiration Expiration External Respiration Gas exchange between lungs and blood Gas Transport Carried out by the cardiovascular system Internal Respiration Gas exchange between the blood and “body cells.” Thursday, November 15, 2018Thursday, November 15, 2018
Respiratory System Function To deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood Carbon Dioxide diffuses out of the blood and into the lungs Thursday, November 15, 2018Thursday, November 15, 2018
Respiration Four Processes Breathing Inspiration (Inhaling of air) Expiration (Exhaling of air) External Respiration Process of gas exchange between the lungs and blood Gas Transport Carried out by the cardiovascular system (Distribution of oxygen, and collection of carbon dioxide, throughout the body) Internal Respiration Process of gas exchange between blood and other body cells Thursday, November 15, 2018Thursday, November 15, 2018

Parts of the Respiratory System Nose Nostrils Hair Mucus Pharynx Throat Tonsils located in this region Larynx Contains the epiglottis Flap responsible for preventing food from entering lungs Adam’s Apple Protects the larynx Thursday, November 15, 2018Thursday, November 15, 2018
Parts Continued Trachea Bronchi Bronchioles Alveoli (Sacs) The windpipe Contains globlet cells that produce mucus Bronchi Two tubes that branch from trachea to left and right lungs Bronchioles Alveoli (Sacs) Where the gas exchange occurs in the lungs.

Other Information Lungs Pair of cone-shaped bodies that occupy the thorax Contain the alveoli Thursday, November 15, 2018Thursday, November 15, 2018
Gas Exchange The differences in pressure, outside the lungs in comparison to inside the lungs, assist with the diffusion process Thursday, November 15, 2018Thursday, November 15, 2018
Lung Volumes and Capacities Revisit V Tidal Volume About 500 ml Amount of air inspired during normal breathing Inspiratory Reserve Volume About 3100 ml Additional amount of air that can be forced inhaled after normal inspiration Thursday, November 15, 2018Thursday, November 15, 2018
Lung Volumes Expiratory Reserve Volume Residual Volume About 1200 ml Additional amount of air that can be force exhaled after expiration of normal volume Residual Volume Volume of air still remaining in the lungs after expiratory reserve volume is exhaled Thursday, November 15, 2018Thursday, November 15, 2018
