Comment calmer les crises d’angoisses :

Dans ta tête, il y a ce qu’on appelle le nerf sympathique et le nerf parasympathique.

Quand tu te sens submergé.e par pleins de choses, le nerf sympathique s’active : le rythme de ton cœur s’accélère, tu transpire, t’arrive plus trop à respirer…

Le nerf parasympathique, lui, fait en sorte que tes muscles se détendent et que tu ai une bonne respiration.

Ses deux nerfs ne peuvent pas s’activer en même donc quand tu te sens mal il faut essayer d’activer le nerf parasympathique.

Pour ça il faut que tu calme ta respiration, essaie de passer le même temps à inspirer qu’à expirer, et puis tu peux aussi t’entourer d’une personne que t’apprécie. Cette personne peut te rassurer.

Le but, c’est vraiment d’avoir la respiration la plus lente, même si c’est dur.

Sur ce, je te souhaite une bonne journée 😘❤️✨

The Stomata in Plants

The stomata plays a key role in the respiration of plants. The stomata are pores found on the epidermis of leaves. However stomata can also be found on the stem on some plants. Stomata are multiple stomas. The image below shows stomata under a microscope, and the one below that is an image of stoma found on the web.

The stoma is made up of guard cells (the sausage like shape in the image above) and is surrounded by the epidermal cell and the subsidiary cell.

These guard cells open when the stomata have taken in a lot of water (this is called the turgid state). They close when the opposite happens (this is called the flacid state).

Stomata open to for the uptake of carbon dioxide and release of oxygen. They close for the uptake of oxygen and release of carbon dioxide.

A problem that plants face is the loss of water. To prevent this as much as possible, the stomata open for a short amount of time before closing.

What is the Difference Between Breathing and Respiration? 

Breathing, also known as pulmonary ventilation, is how air is moved into and out of the lungs. This physical act involves two main phases: inhalation (or inspiration) and exhalation (or expiration). 

Inhalation: When you inhale, the diaphragm tightens and shifts downward, increasing the chest cavity’s size. At the same time, the intercostal muscles between the ribs contract, causing the rib cage to expand. This expansion lowers the pressure within the lungs compared to the external atmosphere, allowing air to flow into the lungs. 

Exhalation: Exhalation involves pushing air out of the lungs. This happens when the diaphragm and intercostal muscles relax, decreasing the volume of the chest cavity. The pressure inside the lungs then becomes higher than the outside atmosphere, driving air out through the respiratory passages. 

Breathing is an essential process for delivering oxygen to the body and removing carbon dioxide, a waste product of cellular metabolism. Without breathing, cells would not receive the oxygen necessary for survival, and carbon dioxide would accumulate to toxic levels. 

What is Respiration?

Respiration, on the other hand, is a biochemical process within the cells. It involves the conversion of glucose and oxygen into energy, carbon dioxide, and water. This process is vital for producing the energy required for various cellular activities. 

Cellular Respiration

Cellular respiration can be broken down into three main stages: 

Glycolysis: This occurs in the cytoplasm of the cell, where glucose is split into two molecules of pyruvate, generating a small amount of energy (ATP) and producing NADH. 

Krebs Cycle (Citric Acid Cycle): This takes place in the mitochondria. The pyruvate is further broken down, producing more NADH and FADH2, and releasing carbon dioxide as a byproduct. 

Electron Transport Chain (ETC): Also in the mitochondria, the NADH and FADH2 generated in the previous steps donate electrons to the ETC, creating a flow of protons that drives the production of a large amount of ATP. Oxygen acts as the final electron acceptor and combines with protons to form water. 

Aerobic vs Anaerobic Respiration

Respiration can be either aerobic or anaerobic. Aerobic respiration requires oxygen and produces a significant amount of ATP. Anaerobic respiration, which occurs when oxygen is scarce, produces less ATP and results in byproducts like lactic acid or ethanol. 

Difference between Breathing and Respiration

While both breathing and respiration are crucial for sustaining life, they serve different functions and occur in different locations within the body. Here’s a detailed comparison: 

Breathing

Definition: Breathing, or ventilation, is the physical process of moving air in and out of the lungs.

Involves: The respiratory muscles, particularly the diaphragm and the intercostal muscles, which help in the expansion and contraction of the chest cavity.

Purpose: To bring oxygen into the lungs and remove carbon dioxide from the body.

Phases:

Inhalation (Inspiration): The process of taking air into the lungs. The diaphragm contracts and moves downward, while the rib cage expands, creating a vacuum that pulls air into the lungs.

Exhalation (Expiration): The process of expelling air from the lungs. The diaphragm relaxes and moves upward, and the rib cage contracts, pushing air out of the lungs.

Control: Can be voluntary or involuntary. While we can control our breathing rate and depth consciously, it is primarily regulated involuntarily by the respiratory center in the brainstem in response to the body's needs.

Respiration

Definition: Respiration is a biochemical process that occurs in cells to produce energy.

Involves: Cellular organelles called mitochondria are often referred to as the cell's powerhouses.

Purpose: To convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Types:

Aerobic Respiration: Requires oxygen and produces a large amount of energy. The overall reaction can be summarized as: Glucose+Oxygen→Carbon Dioxide+Water+Energy (ATP)\text{Glucose} + \text{Oxygen} \rightarrow \text{Carbon Dioxide} + \text{Water} + \text{Energy (ATP)}Glucose+Oxygen→Carbon Dioxide+Water+Energy (ATP)

Anaerobic Respiration: Occurs without oxygen and produces less energy. This type of respiration results in byproducts such as lactic acid (in animals) or ethanol and carbon dioxide (in yeast and some plants).

Stages:

Glycolysis: Occurs in the cytoplasm, where glucose is broken down into pyruvate, producing a small amount of ATP.

Krebs Cycle (Citric Acid Cycle): Takes place in the mitochondria, where pyruvate is further broken down, producing electron carriers and a small amount of ATP.

Electron Transport Chain: Occurs in the inner mitochondrial membrane, where the electron carriers are used to produce a large amount of ATP.

Respiration vs Breathing – Overview

Breathing and respiration are interconnected processes essential for maintaining life. Breathing is the mechanical process that facilitates oxygen intake and carbon dioxide expulsion. Respiration is the cellular process that uses the oxygen delivered by breathing to produce energy, which powers all bodily functions. Together, they form a vital system ensuring that cells receive the oxygen they need and remove the carbon dioxide they produce. 

Understanding the distinction between breathing and respiration is fundamental in biology. Breathing is the external, mechanical process of moving air into and out of the lungs, while respiration is the internal, biochemical process of generating energy at the cellular level. Both processes are crucial for life, supporting each other to maintain the body’s overall function.

THE RESPIRATION SYSTEM:

part 2: aerobic & anaerobic respiration

part 1 | part 2 | part 3 coming soon

what is aerobic respiration?

aerobic respiration is a chemical reaction that happens in your body.

it requires oxygen

produces a lot of energy.

when does it happen?

happens when there is plenty of oxygen available (so when you're doing normal, everyday activities

just normally breathing

what is anaerobic respiration?

anaerobic respiration does not need/ require oxygen

produces lesser energy than aerobic respiration.

when does it happen?

happens when the body has no oxygen/ has run out (so during strenuous exercise like running or sports which make you tired)
