Study Notes
Fisiología Respiratoria
- The cell's primary function is to generate energy through cellular respiration, producing ATP, CO2, and water.
- The process of cellular respiration requires oxygen, which is essential for energy production.
- There are two types of cellular respiration: anaerobic (without oxygen) and aerobic (with oxygen).
Anaerobic Respiration
- Anaerobic respiration produces only 2 ATP molecules.
- It occurs in the absence of oxygen.
Aerobic Respiration
- Aerobic respiration produces 36 ATP molecules.
- It requires oxygen and is a more efficient process than anaerobic respiration.
Glucólisis
- Glucólisis is a process in which glucose is converted into pyruvate, producing ATP.
- It occurs in the cytoplasm and is the first step in cellular respiration.
Ciclo de Krebs
- The Krebs cycle (also known as the citric acid cycle) is a series of reactions that occur in the mitochondria.
- It produces ATP, NADH, and FADH2 as byproducts.
- The Krebs cycle is the second stage of cellular respiration.
Transporte de Protones
- Proton transport is the process by which protons are pumped across the inner mitochondrial membrane.
- It generates a proton gradient, which is used to produce ATP.
Fosforilación Oxidativa
- Oxidative phosphorylation is the process by which ATP is generated using the energy from the proton gradient.
- It occurs in the inner mitochondrial membrane and is the final stage of cellular respiration.
Respiración Celular
- Cellular respiration is the process by which cells generate energy from glucose.
- It involves the breakdown of glucose into ATP, CO2, and water.
Respiración Externa
- External respiration is the process of exchanging oxygen and carbon dioxide between the lungs and the environment.
- It involves the movement of air in and out of the lungs.
Sistema Respiratorio
- The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide.
- It consists of the nose, mouth, trachea, bronchi, lungs, and diaphragm.
Sistema Circulatorio
- The circulatory system is responsible for transporting oxygen and carbon dioxide throughout the body.
- It consists of the heart, arteries, veins, and blood vessels.
Embriología
- Embryology is the study of the development of the embryo.
- The respiratory system begins to develop around the fourth week of embryonic development.
Fisiología Pulmonar
- Pulmonary physiology is the study of the functions of the lungs.
- The lungs are responsible for exchanging oxygen and carbon dioxide between the air and the bloodstream.
Maduración Pulmonar
- Pulmonary maturation is the process by which the lungs develop and mature.
- It involves the formation of alveoli, the development of the surfactant, and the growth of the bronchi.
Surfactante
- Surfactant is a substance that reduces the surface tension of water in the alveoli.
- It helps to prevent the collapse of the alveoli during expiration.
Fisiología Respiratoria en el Período Prenatal y Posnatal
- During the prenatal period, the lungs develop and mature, but are not fully functional.
- During the postnatal period, the lungs continue to develop and mature, and become fully functional.
