BIOL 141 Lecture Notes - Lecture 10: Capillary, Respiratory System, Cellular Respiration
Document Summary
Respiratory system notes: what are the main functions of neuronal circuits involved with the heart, altering blood pressure a. i. Cardiac output alters the amount of blood in the arterial system a. ii. This volume impacts the blood pressure: altering how fast blood moves to the lungs b. i. Blood in lungs picks up oxygen needed by cells b. ii. Blood in lungs releases carbon dioxide, a waste that alters the ph of our body: providing sufficient blood moves to the kidneys c. i. Filtration of blood at kidneys depends on blood pressure c. ii. Filtration removes wastes, reabsorb important molecules and maintain blood volume. Respiratory system: respiration has 3 meanings: a. i. The use of oxygen for metabolism: lung structure b. i. Trachea bronchi bronchiole alveolus (once cell thick, site of gas exchange) b. i. 1. Tube-like structures made up of cartilage and smooth muscle. Cells of alveoli: an alveolus is a balloon-like structure at the end of bronchi, contain 3 cell types: b. i.
